Pass the Isaca Isaca Certification CISA Questions and answers with CertsForce

According to the CISA - Certified Information Systems Auditor Study Guide1, the correct answer to your question is A. Encrypt the disk drive. This is because encryption is a logical security measure that can protect data even if the physical device is stolen or lost. Encryption makes thedata unreadable and inaccessible without the proper key or password. The other options are not as effective as encryption in this scenario. Two-factor authentication is a user authentication method that requires two pieces of evidence to verify the user’s identity, such as a password and a code sent to a phone. However, this does not prevent unauthorized access to the data if the laptop is already logged in or if the attacker can bypass the authentication. Enhancing physical security is a preventive measure that can reduce the risk of theft, but it does not guarantee that theft will not occur or that the data will be safe if it does. Requiring the use of cable locks is another preventive measure that can deter thieves, but it can also be easily cut or removed by a determined attacker.

 A heuristic intrusion detection system (IDS) provides the most protection against emerging threats, as it uses behavioral analysis and anomaly detection to identify unknown or zero-day attacks. A heuristic IDS can adapt to changing patterns and learn from previous incidents, making it more effective than a signature-based IDS, which relies on predefined rules and signatures to detect known attacks. A demilitarized zone (DMZ) is a network segment that separates the internal network from the external network, and it can provide some protection against external threats, but not against internal or emerging threats. Real-time updating of antivirus software is important to protect against malware, but it may not be sufficient to prevent new or sophisticated attacks that exploit unknown vulnerabilities. References: CISA Review Manual (Digital Version) 1, page 452-453.

The most important consideration for patching mission critical business application servers against known vulnerabilities is A. Patches are implemented in a test environment prior to rollout into production. This is because patching mission critical business application servers involves a high level of risk and complexity, and requires careful planning and testing before applying the patches to the live environment. Patches may introduce new bugs, errors, or conflicts that could affect the functionality, performance, or security of the application servers, and cause system downtime, data loss, or business disruption1. Therefore, it is essential to implement patches in atest environment first, where the patches can be verified and validated for their effectiveness and compatibility, and any issues or defects can be identified and resolved before they impact the production environment2.

Data caching is the most likely cause of poor performance, data inconsistency and integrity issues in an IT application, because it involves storing frequently accessed data in a temporary memory location (cache) to reduce the latency and bandwidth consumption of retrieving data from the original source. However, data caching can also introduce problems such as stale data (when the cache is not updated with changes made to the original source), cache coherence (when multiple caches store copies of the same data and need to be synchronized), and cache corruption (when the cache is damaged or tampered with).

Database clustering is not a likely cause of poor performance, data inconsistency and integrity issues, because it involves distributing data across multiple servers or nodes to improve availability, scalability and load balancing of database operations. Database clustering can also enhance data consistency and integrity by using replication and synchronization mechanisms to ensure that all nodes have the same view of the data.

Reindexing of the database table is not a likely cause of poor performance, data inconsistency and integrity issues, because it involves rebuilding or reorganizing indexes on tables or views to improve query performance and reduce fragmentation of index pages. Reindexing can also improve data consistency and integrity by ensuring that indexes reflect the current state of the data in the tables or views.

Load balancing is not a likely cause of poor performance, data inconsistency and integrity issues, because it involves distributing workloads across multiple servers or resources to optimize resource utilization, throughput and response time of applications. Load balancing can also enhance data consistency and integrity by using algorithms and protocols to route requests to the most appropriate server or resource based on availability, capacity and performance.

End-user computing (EUC) is a system in which users are able to create working applications besides the divided development process of design, build, test and release that is typically followed by software engineers1. Examples of EUC tools include spreadsheets, databases, low-code/no-code platforms, and generative AI applications2. EUC tools can provide flexibility, efficiency, and innovation for the users, but they also pose significant risks if not properly managed and controlled3.

The greatest risk when relying on reports generated by EUC is that the data may be inaccurate. Data accuracy refers to the extent to which the data in the reports reflect the true values of the underlying information4. Inaccurate data can lead to erroneous decisions, misleading analysis, unreliable reporting, and compliance violations. Some of the factors that can cause data inaccuracy in EUC reports are:

Lack of rigorous testing: EUC tools may not undergo the same level of testing and validation as IT-developed applications, which can result in errors, bugs, or inconsistencies in the data processing and output3.

Lack of version and change control: EUC tools may not have a clear record of the changes made to them over time, which can create confusion, duplication, or loss of data. Users may also modify or overwrite the data without proper authorization or documentation3.

Lack of documentation and reliance on end-user who developed it: EUC tools may not have sufficient documentation to explain their purpose, functionality, assumptions, limitations, and dependencies. Users may also rely on the knowledge and expertise of the original developer, who may not be available or may not have followed best practices3.

Lack of maintenance processes: EUC tools may not have regular updates, backups, or reviews to ensure their functionality and security. Users may also neglect to delete or archive obsolete or redundant data3.

Lack of security: EUC tools may not have adequate access controls, encryption, or authentication mechanisms to protect the data from unauthorized access, modification, or disclosure. Users may also store or share the data in insecure locations or devices3.

Lack of audit trail: EUC tools may not have a traceable history of the data sources, inputs, outputs, calculations, and transformations. Users may also manipulate or falsify the data without detection or accountability3.

Overreliance on manual controls: EUC tools may depend on human intervention to input, verify, or correct the data, which can introduce errors, delays, or biases. Users may also lack the skills or training to use the EUC tools effectively and efficiently3.

The other options are not as great as data inaccuracy when relying on EUC reports. Reports may not work efficiently, reports may not be timely, and historical data may not be available are all potential risks associated with EUC tools, but they are less severe and less frequent than data inaccuracy. Moreover, these risks can be mitigated by improving the performance, scheduling, and storage of the EUC tools. However, data inaccuracy can have a pervasive and lasting impact on the quality and credibility of the reports and the decisions based on them. Therefore, option A is the correct answer.

Stress testing is designed to evaluate a system’s performance under extreme conditions1. It is typically carried out in a test environment that closely mirrors the production environment, using production workloads1. This approach ensures that the test results accurately reflect how the system would perform under similar conditions in the production environment1. Using a test environment also prevents any disruptions or damage to the production environment during testing1.

The most effective control to maintain segregation of duties in a DevOps environment is A. Enforce approval prior to deployment by a member of the team who has not taken part in the development. Segregation of duties (SoD) is a principle that requires multiple actors to complete a task to reduce the risk of fraud, error, or abuse1. In a DevOps environment, where developers and operators work together to deliver software faster and more reliably, SoD may seem to be incompatible or impractical. However, SoD can still be achieved by implementing controls that ensure that no single person can develop, test, and deploy code without oversight or review2.

Enforcing approval prior to deployment by a member of the team who has not taken part in the development is an effective control that ensures that code changes are verified and validated by a peer before they are released to production. This control can help prevent or detect any unauthorized or malicious modifications, errors, or vulnerabilities in the code, and ensure that the code meets the quality and security standards3. This control can also promote collaboration and feedback among the team members, and improve the transparency and accountability of the software delivery process3.

Data analytics is the process of collecting, transforming, analyzing, and visualizing data to gain insights and support decision making1. Data analytics can be used to facilitate the testing of a new account creation process by applying various techniques and methods to evaluate the quality, functionality, performance, and security of the process. One of the approaches that would utilize data analytics to test the new account creation process is to review new account applications submitted in the past month for invalid dates of birth. This approach would involve the following steps:

Extract the data of new account applications from the source system, such as a database or a web service, using appropriate tools and methods.

Transform and clean the data to ensure its accuracy, completeness, consistency, and validity, using techniques such as data profiling, data cleansing, data mapping, and data validation2.

Analyze the data to identify any anomalies, errors, or outliers in the date of birth field, using methods such as descriptive statistics, exploratory data analysis, hypothesis testing, or anomaly detection3.

Visualize the data to present the findings and insights in a clear and understandable way, using tools and techniques such as charts, graphs, dashboards, or reports.

By reviewing new account applications submitted in the past month for invalid dates of birth, the tester can use data analytics to:

Verify if the new account creation process is working as expected and meets the business requirements and specifications for the date of birth field.

Detect any defects or issues in the new account creation process that may cause invalid dates of birth to be accepted or rejected incorrectly.

Measure and monitor the performance and reliability of the new account creation process in terms of data quality, accuracy, and completeness.

Evaluate and improve the test coverage and effectiveness of the new account creation process by identifying any gaps or risks in the test cases or scenarios.

Therefore, option C is the correct answer.

Option A is not correct because attempting to submit new account applications with invalid dates of birth is not a data analytics approach, but a functional testing approach that involves executing test cases or scenarios manually or automatically to validate the behavior and functionality of the new account creation process. Option B is not correct because reviewing the business requirements document for date of birth field requirements is not a data analytics approach, but a requirements analysis approach that involves examining and understanding the needs and expectations of the stakeholders for the new account creation process. Option D is not correct because evaluating configuration settings for date of birth field requirements is not a data analytics approach, but a configuration testing approach that involves verifying if the settings and parameters of the new account creation process are correct and consistent with the requirements.

Beta testing is the process of releasing a near-final version of a software product to a group of external users, known as beta testers, who provide feedback and report bugs based on their real-world experiences. Beta testingoffers various benefits for both the developers and the users of the software product. Some of these benefits are:

It reduces product failure risk via customer validation12.

It helps to test post-launch infrastructure1.

It helps to improve product quality via customer feedback12.

It allows for thorough bug detection and issue resolution3.

It enhances usability and user experience3.

It increases customer satisfaction and loyalty3.

Based on these benefits, the most important advantage of participating in beta testing of software products is D. It enables an organization to gain familiarity with new products and their functionality. By being involved in beta testing, an organization can learn how to use the new product effectively, discover its features and benefits, and provide suggestions for improvement. This can help the organization to adopt the new product faster, easier, and more efficiently when it is officially released. It can also give the organization a competitive edge over other users who are not familiar with the new product.

Tabletop exercises are a type of simulation used to test an organization’s incident response plan12. They involve key stakeholders in a hypothetical scenario to see how they would respond12. This allows management to assess the effectiveness of the incident response process and identify areas for improvement12. Regularly conducting these exercises ensures that the organization is prepared for a real incident and that the incident response process remains effective over time12.

The first step when developing a DLP solution for a large organization is to conduct a data inventory and classification exercise. This step involves identifying and locating all the data assets that the organization owns, generates, or handles, and assigning them to different categories based on their sensitivity, value, and regulatory requirements1. Data inventory and classification is essential for DLP because it helps to determine the scope and objectives of the DLP solution, as well as the appropriate level of protection and monitoring for each data category2. Data inventory and classification also enables the organization to prioritize its DLP efforts based on the risk and impact of data loss or leakage3.

Option B is not correct because identifying approved data workflows across the enterprise is a subsequent step after conducting data inventory and classification. Data workflows are the processes and channels through which data are created, stored, accessed, shared, or transmitted within or outside the organization4. Identifying approved data workflows helps to define the normal and legitimate use of data, as well as to detect and prevent unauthorized or anomalous data activities5. However, before identifying approved data workflows, the organization needs to know what data it has and how it should be classified.

Option C is not correct because conducting a threat analysis against sensitive data usage is another subsequent step after conducting data inventory and classification. Threat analysis is the process of identifying and assessing the potential sources, methods, and impacts of data loss or leakage incidents. Threat analysis helps to design and implement effective DLP controls and countermeasures based on the risk profile of each data category. However, before conducting threat analysis, the organization needs to know what data it has and how it should be classified.

Option D is not correct because creating the DLP policies and templates is the final step after conducting data inventory and classification, identifying approved data workflows, and conducting threat analysis. DLP policies and templates are the rules and configurations that specify how the DLP solution should monitor, detect, report, and respond to data loss or leakage events. DLP policies and templates should be aligned with the organization’s business needs, regulatory obligations, and risk appetite. However, before creating the DLP policies and templates, the organization needs to know what data it has, how it should be classified, how it should be used, and what threats it faces.

 Access to the data center is controlled by a mantrap provides the greatest assurance that only authorized individuals can access a data center. A mantrap is a physical security device that consists of a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens1. A mantrap prevents unauthorized entry by requiring authentication at both doors, such as biometric scanners, card readers, or PIN codes. A mantrap also prevents tailgating, which is the act of following an authorized person into a restricted area without proper authorization2. A mantrap can also detect and trap intruders who attempt to force their way through the doors.

The other options are less effective physical controls for data center access. The data center is patrolled by a security guard is a deterrent measure, but it does not prevent unauthorized access by itself. A security guard may not be able to monitor all entry points, or may be distracted, bribed, or overpowered by intruders. Access to the data center is monitored by video cameras is a detective measure, but it does not prevent unauthorized access either. Video cameras can record the activities of intruders, but they cannot stop them from entering or alert the security personnel in real time. ID badges must be displayed before access is granted is a preventive measure, but it relies on human verification, which can be prone to errors or manipulation. ID badges can also be lost, stolen, or forged by intruders.

A comprehensive asset inventory is the most important factor for the successful establishment of a security vulnerability management program. A security vulnerability management program is a systematic process of identifying, assessing, prioritizing, and remediating vulnerabilities in the organization’s IT environment1. A comprehensive asset inventory is a complete and accurate record of all the hardware, software, and network components that the organization owns or uses2. A comprehensive asset inventory helps the organization to:

Know what assets are in scope for vulnerability scanning and assessment3.

Identify the vulnerabilities that affect each asset and their severity level4.

Prioritize the remediation of vulnerabilities based on the criticality and value of each asset.

Track the status and progress of vulnerability remediation for each asset.

Measure the effectiveness and maturity of the vulnerability management program.

A robust tabletop exercise plan is a simulated scenario that tests the organization’s preparedness and response capabilities for a potential cyberattack or incident. A tabletop exercise plan is useful for validating and improving the organization’s incident response plan, but it is not essential for establishing a security vulnerability management program.

A tested incident response plan is a documented process that defines the roles, responsibilities, and actions of the organization’s personnel in the event of a cyberattack or incident. A tested incident response plan is important for minimizing the impact and restoring normal operations after a security breach, but it is not critical for establishing a security vulnerability management program.

An approved patching policy is a set of rules and guidelines that governs how the organization applies patches and updates to its IT systems and applications. An approved patching policy is a key component of the remediation phase of the vulnerability management program, but it is not sufficient for establishing a security vulnerability management program.

Post-implementation testing is the process of verifying and validating the functionality, performance, and security of a system after it has been deployed to the production environment1. Post-implementation testing is important for ensuring that the system meets the user requirements and expectations, as well as the operational and business objectives. Post-implementation testing also helps to identify and resolve any defects, errors, or issues that may have occurred during the deployment process or that may have been missed during the previous testing stages2.

Therefore, the observation that post-implementation testing is not conducted for all system releases should be of greatest concern to an IS auditor performing an audit of change and release management controls for a new complex system developed by a small in-house IT team. This observation indicates that the system may have quality, reliability, or security problems that could affect the user satisfaction, system performance, or data integrity. This observation also suggests that the change and release management controls are not adequate or effective, as they do not ensure that all system releases are properly tested and validated before and after deployment.

Option A is not correct because access to change testing strategy and results is not restricted to staff outside the IT team is not a major concern for an IS auditor. While it is good practice to limit access to sensitive or confidential information, such as test data or test cases, to authorized personnel only, access to change testing strategy and results may not pose a significant risk to the system or the organization. Moreover, access to change testing strategy and results may be beneficial for some stakeholders outside the IT team, such as business users, project managers, or auditors, who may need to review or evaluate the testing process or outcomes.

Option B is not correct because some user acceptance testing (UAT) was completed by members of the IT team is not a major concern for an IS auditor. User acceptance testing is the process of verifying and validating that the system meets the user requirements and expectations by involving actual or representative users in the testing process3. While it is preferable to have independent and unbiased users perform UAT, it may not be feasible or practical for some organizations, especially those with small or limited resources. Therefore, some UAT may be completed by members of the IT team, as long as they have sufficient knowledge and experience of the user needs and expectations, and as long as they follow the UAT plan and criteria.

Option C is not correct because IT administrators have access to the production and development environment is not a major concern for an IS auditor. IT administrators are responsible for managing and maintaining the IT infrastructure, including the production and development environments4. Therefore, it is reasonable and necessary for them to have access to both environments, as long as they follow the appropriate policies and procedures for accessing, using, and securing them. Moreover, IT administrators may need to perform tasks such as backup, restore, patching, or troubleshooting in both environments.

The most concerning thing for an IS auditor reviewing an IT strategy document is that the strategic IT goals are derived solely from the latest market trends. An IT strategy document is a blueprint that defines how an organization will use technology to achieve its goals. It should be based on a thorough analysis of the organization’s internal and external factors, such as its vision, mission, values, objectives, strengths, weaknesses, opportunities, threats, customers, competitors, regulations, and industry standards. An IT strategy document should also align with the organization’s business strategy and reflect its unique needs and capabilities. If an IT strategy document is derived solely from the latest market trends, it may not be relevant or appropriate for the organization’s specific situation. It may also lack coherence, consistency, feasibility, or sustainability.

The other options are not as concerning as option C. Target architecture is defined at a technical level is not a concern for an IS auditor reviewing an IT strategy document. Target architecture is the desired state of an organization’s IT systems in terms of their structure, functionality, performance, security, interoperability, and integration. Defining target architecture at a technical level can help an IS auditor to understand how the organization plans to achieve its strategic IT goals and what technical requirements and standards it needs to follow. The previous year’s IT strategic goals were not achieved is not a concern for an IS auditor reviewing an IT strategy document. The previous year’s IT strategic goals are the outcomes that the organization intended to accomplish with its IT initiatives in the past year. Not achieving these goals may indicate some challenges or gaps in the organization’s IT performance or execution. However, this does not necessarily affect the quality or validity of the current IT strategy document. An IS auditor should focus on evaluating whether the current IT strategy document is realistic, measurable, achievable, relevant, and time-bound. Financial estimates of new initiatives are disclosed within the document is not a concern for an IS auditor reviewing an IT strategy document. Financial estimates are projections of the costs and benefits of new initiatives that are part of the IT strategy document. Disclosing financial estimates within the document can help an IS auditor to assess whether the new initiatives are aligned with the organization’s budget and resources and whether they provide value for money. References: IT Strategy Template for a Successful Strategic Plan | Gartner, Definitive Guide to Developing anIT Strategy and Roadmap - CioPages, An Example of a Well-Developed IT Strategy Plan - Resolute

The most significant benefit of implementing a control self-assessment (CSA) program and leveraging the internal audit function to test its internal controls annually is that risks are detected earlier. A CSA program is a process that enables business owners and managers to assess and improve their own internal controls on a regular basis, without relying on external auditors or consultants. A CSA program can help identify and mitigate risks, enhance performance, increase accountability, and foster a culture of control within the organization. By leveraging the internal audit function to test its internal controls annually, a small business unit can also obtain independent assurance and validation of its CSA results, as well as recommendations for improvement. This approach can help reduce compliance costs, as external audits may be less frequent or extensive. However, this is not the most significant benefit, as compliance costs are only one aspect of the total cost of risk. Business owners can also focus more on their core roles, as they can delegate some of their control responsibilities to their staff or teams through CSA. However, this is not the most significant benefit, as business owners still need to oversee and monitor their CSA activities and results, and ensure that they align with their strategic objectives and priorities. Line management may also be more motivated to avoid control exceptions, as they are directly involved in assessing and improving their own controls through CSA. However, this is not the most significant benefit, as motivation alone may not be sufficient to ensure effective control design and operation. References: Info Technology & Systems Resources | COBIT, Risk, Governance … - ISACA, IT Governance and Process Maturity

The best recommendation to address the problem of missing IT deadlines on important projects because IT resources are not prioritized properly is to implement project portfolio management (PPM). PPM is the process of analyzing and optimizing the costs, resources, technologies, and processes for all the projects and programs within a portfolio. A portfolio is a collection of projects, programs, and processes that are managed together and aligned with the strategic goals and objectives of the organization. PPM can help the organization to:

Prioritize the most valuable and relevant projects and programs based on their alignment with the organizational strategy, vision, and mission.

Balance the portfolio to ensure that the projects and programs are diversified, feasible, and sustainable, and that they meet the needs and expectations of the stakeholders.

Optimize the allocation, utilization, and coordination of IT resources across the portfolio, such as staff, budget, time, equipment, and software.

Monitor and control the performance and progress of the projects and programs within the portfolio, and evaluate their outcomes and benefits.

By implementing PPM, the organization can improve its IT project delivery and avoid missing deadlines. PPM can also help the organization to increase its efficiency, effectiveness, quality, and value. For more information about PPM, you can refer to the following web search results:

PPM 101: What Is Project Portfolio Management?3

Effective governance over IT infrastructure is indicated by the ability to deliver continuous, reliable performance12. This is because good governance ensures that IT investments support business objectives and produce measurable results towards achieving their strategies2. It involves implementing management and internal controls, strengthening security, financial controls, risk mitigation, and inspection and compliance obligations3. While security awareness programs, the number of servers, and the number of security incidents can be aspects of IT governance, they are not the best indicators of its effectiveness.

A full interruption test is the most realistic and reliable way to ensure that recovery time objectives (RTOs) are met for an organization’s disaster recovery plan (DRP). RTOs are the maximum amount of time that a business can tolerate being offline after a disaster. A full interruption test involves shutting down the primary site and switching over to the backup site, simulating a real disaster scenario. This test can measure the actual time it takes to restore the systems, applications, and functions that are critical for the business continuity. A full interruption test can also reveal any issues or gaps in the DRP that might affect the recovery process.

The other options are not as effective as a full interruption test for ensuring RTOs are met. A cyber resilience test is a type of DR test that focuses on the ability to withstand and recover from cyberattacks. It does not necessarily cover other types of disasters or test the entire DRP. A tabletop test is a low-impact DR test that involves a walkthrough of the DRP with the key stakeholders and staff. It does not involve any actual switching over or testing of the backup systems. A parallel test is a type of DR test that involves running the backup systems alongside the primary systems, without disrupting the normal operations. It does not measure the time it takes to switch over or resume operations at the backup site.

A quality assurance (QA) team is a group of professionals who are responsible for ensuring that the products or services of an organization meet the quality standards and expectations of customers and stakeholders1. A QA team performs various activities, such as:

Planning, designing, and executing quality tests and audits to verify the quality of the products or services1

Identifying, analyzing, and reporting quality issues, defects, or non-conformities1

Recommending and implementing corrective and preventive actions to resolve quality problems and prevent recurrence1

Monitoring and measuring the effectiveness and efficiency of the quality processes and improvements1

Establishing and maintaining quality documentation, records, and reports1

Providing quality training, guidance, and support to the staff and management1

One of the primary responsibilities of a QA team is to implement procedures to facilitate adoption of quality management best practices. Quality management best practices are the methods, techniques, or tools that have been proven to be effective in achieving and maintaining high-quality standards in an organization2. Some examples of quality management best practices are:

Adopting a customer-focused approach that aims to meet or exceed customer requirements and satisfaction2

Implementing a process approach that manages the interrelated activities as a coherent system2

Applying continuous improvement methods that seek to enhance the performance and value of the products or services2

Using evidence-based decision making that relies on factual data and information2

Developing a culture of engagement and empowerment that involves and motivates the people in the organization2

By implementing procedures to facilitate adoption of quality management best practices, a QA team can help the organization achieve the following benefits:

Improve the quality and reliability of the products or services2

Reduce the costs and risks associated with poor quality or non-compliance2

Increase the customer loyalty and retention2

Enhance the reputation and competitiveness of the organization2

Foster a culture of excellence and innovation in the organization2

The other options are not primary responsibilities of a QA team. Creating test data to facilitate the user acceptance testing (UAT) process is a task that can be performed by a QA team, but it is not their main duty. UAT is a process in which the end users test the product or service to ensure that it meets their needs and expectations before it is released or deployed3. A QA team can create test data to simulate real-world scenarios and conditions for UAT, but they are not directly involved in conducting UAT. Managing employee onboarding processes and background checks is not a responsibility of a QA team. Employee onboarding is a process in which new hires are integrated into the organization, while background checks are screenings that verify the identity, credentials, and history of potential employees4. These processes are usually handled by the human resources department or an external agency, not by a QA team. Advising the steering committee on quality management issues and remediation efforts is not a primary responsibility of a QA team. A steering committee is a group of senior executives or managers who provide strategic direction, oversight, and support for a project or program5. A QA team can advise the steering committee on quality management issues and remediation efforts, but they are not accountable for making decisions or implementing actions. Therefore, option D is the correct answer.

 Implementing solutions to correct defects is a responsibility of the development function, not the quality assurance (QA) function. The QA function should ensure that the development process follows the established standards and methodologies, and that the defects are identified and reported. The QA function should not be involved in fixing the defects, as this would compromise its independence and objectivity. The other options are valid responsibilities of the QA function, and they should not raise concern for an IS auditor. References: CISA Review Manual (Digital Version) 1, page 300.

The role of a document owner when implementing a data classification policy in an organization is to classify documents to correctly reflect the level of sensitivity of information they contain. A document owner is the person who is ultimately responsible for the creation, maintenance, and protection of a document, usually a member of senior management or a business unit1. A data classification policy is a plan that defines how the organization categorizesits data based on its value, risk, and regulatory requirements, and how it handles and secures each data category2.

According to the data classification policy template by Netwrix3, one of the roles and responsibilities of the document owner is to assign data classification labels based on the data’s potential impact level. Data classification labels are tags or markings that indicate the sensitivity level of the data, such as public, internal, confidential, or restricted. The document owner should apply the data classification labels to the documents that contain the data, either manually or automatically, using tools and methods such as metadata, watermarks, headers, footers, or encryption. The document owner should also review and update the data classification labels periodically or whenever there is a change in the data’s sensitivity level.

By classifying documents to correctly reflect the level of sensitivity of information they contain, the document owner can help to ensure that the documents are handled in accordance with the data classification policy. This means that the documents are stored, accessed, shared, transmitted, and disposed of in a secure and appropriate manner, based on the rules and controls defined for each data category. This can also help to prevent data loss, leakage, or breach incidents that may cause harm or damage to the organization or its stakeholders.

Therefore, option A is the correct answer.

A CO2 system could be a concern for an IS auditor when used to protect an asset storage closet. While CO2 systems are effective at suppressing fires, they can pose a significant safety risk to personnel. In the event of a fire,the CO2 system would fill the room with carbon dioxide, displacing the oxygen. This could be hazardous to anyone who might be in the room at the time12.

Outsourcing the development of an e-banking solution when in-house technical expertise is not available can significantly reduce start-up costs. This is because the organization can avoid the expenses associated with hiring and training a full-time development team, purchasing necessary hardware and software, and maintaining the system1. While outsourcing can also potentially reduce the risk of system downtime, increase the ability to adapt the system, and provide direct oversight of risks, these benefits are not as immediate or guaranteed as the cost savings123.

The best option for the question is C, information owner. This is because:

The information owner is the person or entity that has the authority and responsibility for the business processes and functions that collect, use, store, and dispose of data1.

The information owner is accountable for ensuring that the data is handled in compliance with the applicable laws, regulations, policies, and standards, such as the GDPR and the PIPEDA1234.

The information owner is in the best position to determine the purpose and necessity of collecting and retaining data, as well as the risks and benefits associated with it1.

The information owner should consult with other stakeholders, such as the risk manager, the database administrator (DBA), and the privacy manager, to establish and implement appropriate data classification policies and procedures2.

Data classification is the process of organizing data in groups based on their attributes and characteristics, and then assigning class labels that describe a set of attributes that hold true for the corresponding data sets345.

Data classification helps organizations to identify, manage, protect, and understand their data, as well as to comply with modern data privacy regulations345.

Data classification also helps to determine appropriate user access levels, which means defining who can access, modify, share, or delete data based on their roles, responsibilities, and needs345.

Therefore, the information owner should be responsible for the data classification in an ERP migration project from local systems to the cloud (option C), as they have the authority and accountability for the data and its protection.

The other options are not correct because:

The information security officer (option A) is responsible for overseeing and coordinating the security policies and practices of the organization that involve data6. The information security officer should advise and assist the information owner on the best practices and standards for data security, but not determine the data classification.

The database administrator (DBA) (option B) is responsible for installing, configuring, monitoring, maintaining, and improving the performance of databases and data stores that contain data5. The DBA should support the information owner in implementing and enforcing the data classification policies and procedures, but not determine them.

The data architect (option D) is responsible for designing, modeling, and documenting the logical and physical structures of databases and data stores that contain data7. The data architect should collaborate with the information owner in creating and maintaining the data classification schema and metadata, but not determine them.

The best recommendation to help prevent the situation where IT support staff were put in a position to make decisions beyond their level of authority during the review of a system disruption incident is to introduce escalation protocols. Escalation protocols are policies and procedures that define who should be notified, involved, or consulted when an incident occurs, how the communication and handover should take place, and what criteria or triggers should be used to escalate the incident to a higher level of authority or expertise2. Escalation protocols help to ensure that:

Incidents are handled by the appropriate staff with the required skills, knowledge, and experience

Incidents are resolved in a timely and effective manner

Incidents are escalated to senior management or specialized teams when necessary

Incidents are documented and reported accurately and transparently

Incidents are analyzed and learned from to prevent recurrence or mitigate impact

Therefore, by introducing escalation protocols, an organization can improve its incident management process and avoid putting IT support staff in a position to make decisions beyond their level of authority.

 A contingency facility is a backup site that can be used to resume business operations in the event of a disaster or disruption at the primary site. The most important consideration for a contingency facility is that it is located a sufficient distance away from the primary site, so that it is not affected by the same event that caused the disruption. For example, if the primary site is damaged by a fire, flood, earthquake, or terrorist attack, the contingency facility should be in a different geographic area that is unlikely to experience the same hazard. This way, the organization can continue to provide its services and products to its customers and stakeholders without interruption.

The other options are not as important as the location of the contingency facility. The badge access controls, the number of business assets, and the identifiability of the sites are secondary factors that may affect the security and efficiency of the contingency facility, but they are not essential for its functionality. Therefore, option C is the correct answer.

 Scope creep is the uncontrolled expansion of a project’s scope, which can result in delays, cost overruns, and quality issues. To mitigate the risk of scope creep, an IS auditor should look for projectchange management controls, which are processes and procedures for managing changes to the project’s scope, schedule, budget, and quality. Project change management controls ensure that changes are properly requested, approved, documented, communicated, and implemented. Source code version control, existence of an architecture review board, and configuration management are also important for software development, but they do not directly address the risk of scope creep. References: ISACA Frameworks: Blueprints for Success, Project Management Institute: A Guide to the Project Management Body of Knowledge

The auditor should verify whether a right-to-audit clause exists (B) next, because it is a contractual provision that grants the auditor the right to access and examine the records, systems, and processes of the SaaS provider. A right-to-audit clause is important for ensuring transparency, accountability, and compliance of the SaaS provider with the customer’s requirements and expectations. A right-to-audit clause can also help the auditor to identify and mitigate any risks or issues related to the SaaS agreement12.

Verifying whether IT management monitors the effectiveness of the environment (A) is not the next step, because it is a part of the ongoing monitoring andevaluation process, not the initial walk-through procedures. The auditor should first establish the scope, objectives, and criteria of the audit before assessing the performance and controls of the SaaS provider.

Verifying whether a third-party security attestation exists © is not the next step, because it is not a mandatory requirement for a SaaS agreement. A third-party security attestation is a report or certificate issued by an independent auditor that evaluates and validates the security controls and practices of the SaaS provider. A third-party security attestation can provide assurance and confidence to the customer, but it does not replace or eliminate the need for a right-to-audit clause3.

Verifying whether service level agreements (SLAs) are defined and monitored (D) is not the next step, because it is not directly related to the audit process. SLAs are contractual agreements that specify the quality, availability, and performance standards of the SaaS provider. SLAs are important for measuring and managing the service delivery and customer satisfaction, but they do not grant or guarantee the right to audit4.

The greatest concern with the IT department and internal IS audit function both reporting to the CIO is the potential compromise of IS audit independence. Auditor independence refers to the impartiality and objectivity of an auditor in conducting an audit, free from conflicts of interest and bias1. It is crucial for ensuring the quality and reliability of financial reporting1. If the IS audit function reports to the CIO, who also oversees the IT department, it could create a conflict of interest that might compromise the impartiality and objectivity of the IS audit function.

The best evidence to determine whether transactions have been executed by authorized employees is audit trails. Audit trails are secure records that catalog events or procedures to provide support documentation. They are used to authenticate security and operational actions, mitigate challenges, or provide proof of compliance and operational integrity2. Audit trails can track and trace the following information related to transactions:

Who initiated, approved, modified, or deleted a transaction

When a transaction occurred (date and time)

Where a transaction took place (location or device)

What type of transaction was performed (action or operation)

Why a transaction was executed (purpose or reason)

By analyzing audit trails, an IS auditor can verify whether transactions have been executed by authorized employees or not. Audit trails can also identify any unauthorized, fraudulent, or erroneous transactions that may have occurred. Audit trails can also help to resolve any disputes or discrepancies that may arise from transactions.

To detect unauthorized disclosure of confidential documents sent over corporate email, monitoring all emails based on pre-defined criteria is the best approach. This involves setting up automated monitoring systems that analyze email content, attachments, and metadata to identify any potential unauthorized disclosures. By defining specific criteria (such as keywords related to confidential information), organizations can proactively detect and prevent leaks. Requiring encryption before sending documents (option A) is important but does not address monitoring for unauthorized disclosures. Firewalls (option B) protect the network but do not specifically focus on email content. Reporting outgoing emails marked as confidential (option C) relies onuser self-reporting and may not catch all incidents12. References: 1(https://www.isaca.org/resources/isaca-journal/past-issues/2010/data-governance-for-privacy-confidentiality-and-compliance-a-holistic-approach) 2(https://www.isaca.org/resources/news-and-trends/newsletters/atisaca/2020/volume-6/best-practices-for-privacy-audits)

The most helpful thing for an IS auditor to review when evaluating an organization’s business processes that are supported by applications and IT systems is the enterprise architecture (EA). EA is the practice of designing a business with a holistic view, considering all of its parts and how they interact. EA defines the overall goals, the strategies that support those goals, and the tactics that are needed to execute those strategies. EA also outlines the ways various components of IT projects interact with one another and with the business processes. By reviewing the EA, an IS auditor can gain a comprehensive understanding of how the organization aligns its IT efforts with its overall mission, business strategy, and priorities. An IS auditor can also assess the effectiveness, efficiency, agility, and continuity of complex business operations.

The other options are not as helpful as option B. A configuration management database (CMDB) is a database that stores and manages information about the components that make up an IT system. A CMDB tracks individual configuration items (CIs), such as hardware, software, or data assets, and their attributes, dependencies, and changes over time. A CMDB can help an IS auditor to monitor the performance, availability, and configuration of IT assets, but it does not provide a holistic view of how they support the business processes. IT portfolio management is the practice of managing IT investments, projects, and activities as a portfolio. IT portfolio management aims to optimize the value, risk, and cost of IT initiatives and align them with the business objectives. IT portfolio management can help an IS auditor to evaluate the return on IT investments and the alignment of IT projects with the business strategy, but it does not provide a detailed view of how they support the business processes. IT service management (ITSM) is the practice of planning, implementing, managing, and optimizing IT services to meet the needs of end users and customers. ITSM focuses on delivering IT as a service using standardized processes and best practices. ITSM can help an IS auditor to review the quality, efficiency, and effectiveness of IT service delivery and support, but it does not provide a comprehensive view of how they support the business processes. References: What is enterprise architecture (EA)? - RingCentral, What is a configuration management database (CMDB)? - Red Hat, IT Portfolio Management Strategies | Smartsheet, What is IT service management (ITSM)? | IBM

Hashing is a technique that transforms data into a fixed-length value, called a hash or a digest, that uniquely represents the original data. Hashing can be used to validate the integrity of data communicated between production databases and a big data analytics system by comparing the hash values of the data before and after the communication. If the hash values match, the data has not been altered; if they differ, the data has been tampered with or corrupted. Hashing is a better security control than encrypting, running and comparing the count function, or hosting a digital certificate for this purpose because:

Encrypting in-scope data sets can protect the confidentiality of the data, but not necessarily the integrity. Encryption algorithms can be broken or bypassed by malicious actors, or encryption keys can be compromised or lost. Moreover, encryption adds overhead to the communication process and may affect the performance of the big data analytics system.

Running and comparing the count function within the in-scope data sets can only verify the number of records or elements in the data sets, but not the content or quality of the data. The count function cannot detect any changes or errors in the data values, such as missing, duplicated, corrupted, or manipulated data.

Hosting a digital certificate for in-scope data sets can provide authentication and non-repudiation for the data sources, but not integrity for the data itself. A digital certificate is a document that contains information about the identity and public key of an entity, such as a person, organization, or device. A digital certificate does not contain or verify the actual data that is communicated between production databases and a big data analytics system.

A virtual tape library (VTL) is a disk-based backup system that emulates a tape library. It provides faster backup and recovery than traditional tape systems, and it can be integrated with data deduplication and replication technologies to enhance disaster recovery. A VTL can also be replicated to an offsite location for additional protection. A VTL is the best disaster recovery solution for an environment where data virtualization is used, because it can handle large volumes of data, support multiple backup applications, and provide consistent performance.

Onsite disk-based backup systems (A) are not the best disaster recovery solution, because they are vulnerable to the same risks as the primary data center, such as fire, flood, power outage, or sabotage. Tape-based backup systems (B) are not the best disaster recovery solution, because they are slow, prone to errors, and require manual intervention. Redundant array of independent disks (RAID) (D) is not a backup system, but a storage technology that improves performance and fault tolerance by distributing data across multiple disks. RAID does not protect against data corruption, human error, or malicious attacks.

A post-implementation change review is the best compensating control against segregation of duties conflicts in new code development. This process involves a thorough review of the changes after they have been implemented to ensure that they meet their objectives and that the stakeholders are satisfied with the results1. It provides an opportunity to identify and correct any issues or conflicts that may have arisen during the development and implementation process. While other options like adding developers to the change approval board, limiting code deployment access to a small number of people, and creating staging environments can also serve as compensating controls, a post-implementation change review provides a more comprehensive and effective control mechanism21.

The IS auditor’s greatest concern when reviewing a business case for a proposed implementation of a third-party system should be A. Lack of ongoing maintenance costs. This is because ongoing maintenance costs are an essential part of the total cost of ownership (TCO) of a third-party system, and they can have a significant impact on the return on investment (ROI) and the feasibility of the project. If the business case does not include ongoing maintenance costs, it may underestimate the true cost of the project and overestimate the benefits. This could lead to poor decision making and unrealistic expectations.

Lack of training materials (B), lack of plan for pilot implementation ©, and lack of detailed work breakdown structure (D) are also potential issues that could affect the quality and success of the project, but they are not as critical as lack of ongoing maintenance costs. Training materials can be developed or acquired later, pilot implementation can be planned during the project initiation or planning phase, and work breakdown structure can be refined as the project progresses. However, ongoing maintenance costs are difficult to change or estimate once the project is approved and implemented, and they can have long-term implications for the organization. Therefore, they should be included and analyzed in the business case.

Among the options provided, fingerprint scanning has the highest rate of false negatives. False negatives occur when a biometric system fails to recognize an authentic individual. Factors such as skin conditions (wet, dry, greasy), finger injuries, and inadequate scanning can contribute to false negatives in fingerprint scanning1. In comparison, iris recognition23, face recognition45, and retina scanning67 generally have lower rates of false negatives.

The primary purpose of an incident response plan is to reduce the impact of an adverse event on information assets. An incident response plan is a set of instructions and procedures that guide the organization’s actions in the event of a security breach, cyberattack, or other disruption that affects its information systems and data. An incident response plan aims to:

Detect and identify the incident as soon as possible.

Contain and isolate the incident to prevent further damage or spread.

Analyze and investigate the incident to determine its cause, scope, and impact.

Eradicate and eliminate the incident and its root causes from the affected systems and data.

Recover and restore the normal operations and functionality of the systems and data.

Learn and improve from the incident by documenting the lessons learned, best practices, and recommendations for future prevention and mitigation.

By following an incident response plan, the organization can minimize the negative consequences of an adverse event on its information assets, such as:

Loss or corruption of data or information.

Disclosure or theft of confidential or sensitive data or information.

Interruption or degradation of system or service availability or performance.

Legal or regulatory noncompliance or liability.

Financial or reputational loss or damage.

An incident response plan also helps the organization to demonstrate its due diligence and accountability in protecting its information assets and complying with its legal and contractual obligations.

The other options are not the primary purpose of an incident response plan, although they may be secondary benefits or outcomes of having one.

Increasing the effectiveness of preventive controls is not the primary purpose of an incident response plan. Preventive controls are controls that aim to prevent or deter incidents from occurring in the first place, such as firewalls, antivirus software, encryption, authentication, etc. An incident response plan is a reactive control that deals with incidents after they have occurred. However, an incident response plan may help to improve the effectiveness of preventive controls by identifying and addressing their weaknesses or gaps.

Reducing the maximum tolerable downtime (MTD) of impacted systems is not the primary purpose of an incident response plan. MTD is a measure of how long an organization can tolerate a system or service outage before it causes unacceptable harm or loss to its business operations or objectives. An incident response plan may help to reduce the MTD of impacted systems by facilitating a faster and smoother recovery process. However, reducing the MTD is not the main goal of an incident response plan, but rather a desired outcome.

Increasing awareness of impacts from adverse events to IT systems is not the primary purpose of an incident response plan. Awareness is a state of being informed or conscious of something. An incident response plan may help to increase awareness of impacts from adverse events to IT systems by providing information and communication channels for stakeholders, such as management, employees, customers, regulators, etc. However, increasing awareness is not the main objective of an incident response plan, but rather a means to achieve other objectives, such as reducing impact, ensuring compliance, or maintaining trust.

The most important thing for incident management to focus on when addressing an issue that causes an outage is restoring the system to operational state as quickly as possible. Incident management is the process of detecting, investigating, and resolving incidents that disrupt or degrade a service or system. An incident is an unplanned event that affects the normal functioning or quality of a service or system. An outage is a type of incident that causes a complete loss of service or system availability. The main goal of incident management is to restore the service or system to its operational state as quickly as possible, minimizing the impact on users and business operations.

*The other options are not as important as option B. Analyzing the root cause of the outage to ensure the incident will not re-occur is a valuable activity, but not the most important thing for incident management to focus on when addressing an issue that causes an outage. Root cause analysis is a process of identifying and eliminating the underlying factors that caused an incident or problem. Root cause analysis can help to prevent or reduce the likelihood of similar incidents or problems in the future. However, root cause analysis is usually performed after the incident has been resolved and the service or system has been restored. Ensuring all resolution steps are fully documented prior to returning the system to service is a good practice, but not the most important thing for incident management to focus on when addressing an issue that causes an outage. Documentation is a process of recording and maintaining information about an incident and its resolution steps. Documentation can help to improve communication, accountability, learning, and improvement within incident management. However, documentation should not delay or interfere with the restoration of the service or system. Rolling back the unsuccessful change to the previous state is a possible solution, but not the most important thing for incident management to focus on when addressing an issue that causes an outage. Rolling back is a process of reverting a change that has been applied to a service or system that caused an incident or problem. Rolling back can help to restore the service or system to its previous state before the change was made. 

 The record-locking option of a database management system (DBMS) serves to eliminate the risk of concurrent updates to a record by different users or transactions. Record locking is a technique of preventing simultaneous access to data in a database, to prevent inconsistent results1. For example, if two bank clerks try to update the same bank account for two different transactions, record locking can ensure that only one clerk can modify the record at a time, while the other has to wait until the lock is released. This way, the record will reflect both transactions correctly and avoid data corruption.

Record locking does not serve to allow database administrators (DBAs) to record the activities of users. This is a function of auditing or logging, which can track the actions performed by users on the database2. Record locking does not affect the ability of DBAs to monitor or audit user activities.

Record locking does not serve to restrict users from changing certain values within records. This is a function of access control or authorization, which can enforce rules or policies on what data users can view or modify2. Record locking does not affect the permissions or privileges of users on the database.

Record locking does not serve to allow users to lock others out of their files. This is a function of encryption or password protection, which can secure files from unauthorized access or modification3. Record locking does not affect the security or confidentiality of files on the database.

 The primary factor to determine system criticality is the maximum allowable downtime (MAD), which is the maximum period of time that a system can be unavailable before causing significant damage or risk to the organization. TheMAD reflects the business impact and the recovery requirements of the system, and it can be used to prioritize the systems and allocate the resources for disaster recovery planning. The other options are not as important as the MAD, and they may vary depending on the system characteristics and the recovery strategy. The recovery point objective (RPO) is the maximum amount of data loss that is acceptable for a system. The mean time to restore (MTTR) is the average time required to restore a system after a failure. The key performance indicators (KPIs) are metrics that measure the performance and effectiveness of a system. References: CISA Review Manual (Digital Version) 1, page 468-469.

QUESTIO NO. 704

Which of the following would provide the BEST evidence that a cloud provider's change management process is effective?

A. Minutes from regular change management meetings with the vendor

B. Written assurances from the vendor's CEO and CIO

C. The results of a third-party review provided by the vendor

D. A copy of change management policies provided by the vendor

Answer: C

The results of a third-party review provided by the vendor would provide the best evidence that a cloud provider’s change management process is effective, because it would be an independent and objective assessment of the vendor’s compliance with best practices and standards for managing changes in the cloud environment. A third-party review would also include testing of the vendor’s change management controls and procedures, and provide recommendations for improvement if needed.

Minutes from regular change management meetings with the vendor would not provide sufficient evidence, because they would only reflect the vendor’s self-reported information and may not capture all the changes that occurred or their impact on the cloud services. Written assurances from the vendor’s CEO and CIO would also not provide sufficient evidence, because they would be based on the vendor’s own opinion and may not be verified by external sources. A copy of change management policies provided by the vendor would not provide sufficient evidence, because it would only show the vendor’s intended approach to change management, but not how it is implemented or monitored in practice.

 The best action that audit management should consider first is to reassign the audit to an internal audit subject matter expert. This is because cloud service audits require specialized knowledge and skills to assess the risks and controls associated with the cloud service provider and the cloud service customer. An IS auditor who is unfamiliar with the technologies in use and their associated risks to the business may not be able to perform an effective and efficient audit, and may miss important issues or provide inaccurate recommendations. Therefore, it is important to ensure that the IS auditor assigned to the cloud service audit has the appropriate competence and experience.

The other options are not as good as reassigning the audit to an internal audit subject matter expert. Conducting a follow-up audit after a suitable period has elapsed may not address the quality issues of the initial audit, and may also delay the identification and remediation of any problems. Rescheduling the audit assignment for the next financial year may expose the organization to unnecessary risks and may not meet the audit objectives or expectations. Extending the duration of the audit to give the auditor more time may not be feasible or cost-effective, and may not guarantee that the auditor will acquire the necessary knowledge and skills in time.

Obtaining management’s consent to the testing scope in writing is the most important step prior to finalizing the scope of testing, as it ensures that the penetration testers have the authorization and approval to perform the testing activities. It also protects them from any legal liabilities or accusations of unauthorized access or damage. The other options are not as important as obtaining management’s consent, and they may vary depending on the specific situation and agreement. For example, some systems may not be excluded from the testing scope, and some tests may not be restricted to the test environment. References: CISA Review Manual (Digital Version) 1, page 381-382.

An insider attack poses the greatest risk to an organization’s most sensitive data. An insider attack is a type of cyberattack that is carried out by someone who has legitimate access to the organization’s network, systems, or data, such as an employee, contractor, or business partner. An insider attack can be intentional or unintentional, malicious or negligent, and can have various motives, such as financial gain, revenge, espionage, sabotage, or curiosity.

An insider attack poses the greatest risk to an organization’s most sensitive data because:

An insider has a high level of trust and privilege within the organization, which allows them to bypass security controls and access confidential or restricted data without raising suspicion or detection.

An insider has a deep knowledge of the organization’s operations, processes, policies, and vulnerabilities, which enables them to exploit them effectively and cause maximum damage or disruption.

An insider can use various techniques and tools to conceal their identity and actions, such as encryption, steganography, deletion, or alteration of logs or evidence.

An insider can cause significant harm or loss to the organization in terms of data integrity, availability, confidentiality, reputation, compliance, and profitability.

According to the 2023 Cost of Insider Threats Global Report by Ponemon Institute and ObserveIT 1, the average annual cost of insider threats for organizations worldwide was $11.45 million in 2022, a 31% increase from 2018. The report also found that the average number of incidents per organization was 77 in 2022, a 47% increase from 2018. The report classified insider threats into three categories: careless or negligent employees or contractors, criminal or malicious insiders, and credential thieves. The report revealed that careless or negligent insiders were the most common and costly type of insider threat, accounting for 62% of all incidents and $4.58 million in costs.

The other options are not the greatest risk to an organization’s most sensitive data, although they can still pose significant threats.

A password attack is a type of cyberattack that attempts to guess or crack a user’s password to gain unauthorized access to their account or system. A password attack can use various methods, such as brute force, dictionary, rainbow table, phishing, keylogging, or social engineering. A password attack can compromise the security and privacy of the user’s data and information. However, a password attack can be prevented or mitigated by using strong and unique passwords, changing passwords frequently, enabling multi-factor authentication (MFA), and avoiding clicking on suspicious links or attachments.

An eavesdropping attack is a type of cyberattack that intercepts or monitors the communication between two parties without their knowledge or consent. An eavesdropping attack can use various techniques, such as wiretapping, packet sniffing, man-in-the-middle (MITM), or side-channel. An eavesdropping attack can expose the content and metadata of the communication, such as messages, files, voice calls, emails, etc. However, an eavesdropping attack can be prevented or mitigated by using encryption, authentication, digital signatures, VPNs (virtual private networks), or secure protocols.

A spear phishing attack is a type of phishing attack that targets a specific individual or group with personalized and convincing emails that appear to come from a trusted source. A spear phishing attack aims to trick the recipient into clicking on a malicious link or attachment that can infect their device with malware or steal their credentials or data. A spear phishing attack can compromise the security and privacy of the recipient’s data and information. However, a spear phishing attack can be prevented or mitigated by verifying the sender’s identity and email address, checking the email content for spelling and grammar errors, hovering over links before clicking on them (or not clicking at all), scanning attachments for viruses before opening them (or not opening at all), and reporting suspicious emails to IT security staff.

The most important action before the audit work begins is to establish control objectives. Control objectives are the specific goals or outcomes that the audit intends to achieve or verify in relation to the information protection in the application1. Control objectives provide the basis for designing and performing the audit procedures, evaluating the audit evidence, and reporting the audit findings and recommendations2. Control objectives also help to align the audit scope and criteria with the business needs and expectations, and to ensure that the audit is relevant, reliable, and efficient3.

Some examples of control objectives for an information protection audit are:

To ensure that the information stored in the application is classified according to its sensitivity, value, and regulatory requirements

To ensure that the information stored in the application is encrypted, masked, or anonymized as appropriate

To ensure that the information stored in the application is accessible only by authorized users and processes

To ensure that the information stored in the application is backed up, restored, and retained according to the business continuity and retention policies

To ensure that the information stored in the application is monitored, logged, and audited for any unauthorized or anomalous activities

Therefore, option B is the correct answer.

Option A is not correct because reviewing remediation reports is not the most important action before the audit work begins. Remediation reports are documents that describe how previous audit findings or issues have been resolved or addressed by the auditee4. While reviewing remediation reports may be useful for understanding the current state of information protection in the application, it is not a prerequisite for defining the control objectives of the audit.

Option C is not correct because assessing the threat landscape is not the most important action before the audit work begins. The threat landscape is the set of potential sources, methods, and impacts of cyberattacks or data breaches that may affect the information stored in the application5. While assessing the threat landscape may be helpful for identifying and prioritizing the risks and vulnerabilities of information protection in the application, it is not a prerequisite for defining the control objectives of the audit.

Option D is not correct because performing penetration testing is not the most important action before the audit work begins. Penetration testing is a technique that simulates real-world cyberattacks or data breaches to test the security and resilience of information systems or applications. 

The best reason to implement a data retention policy is to limit the liability associated with storing and protecting information. A data retention policy is a business’ established protocol for maintaining information, typically defining what data needs to be retained, the format in which it should be kept, how long it should be stored for, whether it should eventually be archived or deleted, who has the authority to dispose of it, and what procedure to follow in the event of a policy violation1. A data retention policy can help an organization to:

Comply with legal and regulatory requirements that mandate the retention and disposal of certain types of data, such as financial records, health records, or personal data

Reduce the risk of data breaches, theft, loss, or corruption by minimizing the amount of data stored and ensuring proper security measures are in place

Save costs and resources by optimizing the use of storage space and reducing the need for backup and recovery operations

Enhance operational efficiency and performance by eliminating unnecessary or outdated data and improving data quality and accessibility

Support business continuity and disaster recovery plans by ensuring critical data is available and recoverable in case of an emergency

Facilitate audit trails and investigations by providing evidence of data authenticity, integrity, and provenance

Therefore, by implementing a data retention policy, an organization can limit its liability associated with storing and protecting information, as well as improve its data governance and management practices.

Capability maturity models (CMMs) are frameworks that help organizations assess and improve their processes in various domains, such as software development, project management, service delivery, and cybersecurity1. CMMs define different levels of process maturity, from initial to optimized, and describe the characteristics and best practices of each level. By using CMMs, organizations can benchmark their current processes against a common standard, identify gaps and weaknesses, and implement improvement actions to achieve higher levels of process maturity2. CMMs can also help organizations align their processes with their strategic goals, measure their performance, and increase their efficiency, quality, and customer satisfaction3.

Therefore, the use of CMMs would best enhance a process improvement program, as they provide a systematic and structured approach to evaluate and improve processes based on proven principles and practices. Option C is the correct answer.

Option A is not correct because model-based design notations are graphical or textual languages that help designers specify, visualize, and document the structure and behavior of systems4. While they can be useful for designing and communicating complex systems, they do not directly address the process improvement aspect of a program.

Option B is not correct because balanced scorecard is a strategic management tool that helps organizations translate their vision and mission into measurable objectives and indicators. While it can be useful for monitoring and evaluating the performance of a program, it does not provide specific guidance on how to improve processes.

Option D is not correct because project management methodologies are sets of principles and practices that help organizations plan, execute, and control projects. While they can be useful for managing the scope, schedule, cost, quality, and risk of a program, they do not focus on the process improvement aspect of a program.

 An organization considering the outsourcing of a business application should first conduct a cost-benefit analysis to evaluate the feasibility, viability and desirability of the outsourcing decision. A cost-benefit analysis should compare the costs and benefits of outsourcing versus keeping the application in-house, taking into account factors such as financial, operational, strategic, legal, regulatory, security and quality aspects. A cost-benefit analysis should also identify the risks and opportunities associated with outsourcing, and provide a basis for defining the service level requirements, performing a vulnerability assessment, and issuing a request for proposal (RFP) in the subsequent stages of the outsourcing process. References: Info Technology &Systems Resources | COBIT, Risk, Governance … - ISACA, CISACertification | Certified Information Systems Auditor | ISACA

Assessing and tracking all compliance audit findings is the best way to support the effectiveness of a compliance program. This allows an organization to identify areas of non-compliance, take corrective action, and monitor improvements over time12. While implementing an awareness plan, using a governance, risk, and compliance (GRC) tool, and monitoring applicable regulations can contribute to a compliance program, they do not provide the same level of continuous improvement and effectiveness as assessing and tracking audit findings.
