The charging method for IS resources is the way that the IS function allocates its costs to the users or business units that consume its services. The charging method can affect the behavior and incentives of the users and the IS function, as well as the efficiency and effectiveness of the IS resources. Therefore, choosing an appropriate charging method is an important decision for the IS function and its stakeholders.

One of the possible charging methods is to charge specific costs that can be tied back to specific usage. This means that the IS function tracks and measures the actual consumption of each user or business unit for each IS service, and charges them accordingly. For example, if a user uses 10 GB of storage space, 5 hours of CPU time, and 100 MB of network bandwidth, the IS function will charge them based on the unit costs of these resources. This charging method has the advantage of encouraging the most efficient use of IS resources, as it provides clear and accurate feedback to the users about their consumption and costs, and motivates them to optimize their usage and avoid waste or overuse. This charging method also aligns the interests of the IS function and the users, as both parties benefit from reducing costs and improving efficiency.

The other possible charging methods are:

Total utilization to achieve full operating capacity: This means that the IS function charges a fixed amount to each user or business unit based on their proportion of the total operating capacity of the IS resources. For example, if a user or business unit has 10% of the total computing power allocated to them, they will pay 10% of the total IS costs. This charging method has the disadvantage of discouraging efficient use of IS resources, as it does not reflect the actual consumption or usage of each user or business unit, and does not provide any incentive to reduce costs or improve efficiency. This charging method also creates a mismatch between the interests of the IS function and the users, as the IS function benefits from increasing costs and capacity, while the users bear the burden of paying for them.

Residual income in excess of actual incurred costs: This means that the IS function charges a markup or profit margin on top of its actual incurred costs to each user or business unit.For example, if a user or business unit consumes $100 worth of IS resources, the IS function will charge them $120, where $20 is the residual income for the IS function. This charging method has the disadvantage of discouraging efficient use of IS resources, as it increases the costs for the users and reduces their value for money. This charging method also creates a conflict between the interests of the IS function and the users, as the IS function benefits from increasing costs and profits, while the users suffer from paying more than they should.

Allocations based on the ability to absorb charges: This means that the IS function charges different amounts to different users or business units based on their ability to pay or their profitability. For example, if a user or business unit is more profitable or has a higher budget than another user or business unit, they will pay more for the same amount of IS resources. This charging method has the disadvantage of discouraging efficient use of IS resources, as it does not reflect the actual consumption or usage of each user or business unit, and does not provide any incentive to reduce costs or improve efficiency. This charging method also creates an unfair and arbitrary distribution of costs among the users or business units, as some paymore than others for no valid reason. References: 1: Charging Methods for IT Services - IT Process Wiki 2: IT Chargeback Methods - CIO Wiki 3: IT Chargeback - Wikipedia

 A computer forensic audit is a process of collecting, preserving, analyzing, and presenting digital evidence from electronic devices in a legally admissible manner. It is most relevant in situations where data loss due to hacking of servers occurs, as it can help to identify the source, method, and extent of the attack, as well as recover the lost or damaged data. The other options are not as suitable for a computer forensic audit, as they relate to internal control issues, data quality issues, orsystem maintenance issues, which can be addressed by other types of audits or reviews. References: CISA Review Manual (Digital Version), Domain 4: Information Systems Operations and Business Resilience, Section 4.5 Computer Forensics1

 The advantage of using agile software development methodology over the waterfall methodology is that it allows for quicker deliverables. Agile software development is an iterative and incremental approach that emphasizes customer feedback, collaboration, and adaptation. Agile software development delivers working software in short cycles, called sprints, that typically last from two to four weeks. This enables the development team to respond to changing requirements, deliver value faster, and improve quality. Waterfall software development is a linear and sequential approach that follows a predefined set of phases, such as planning, analysis, design, implementation, testing, and maintenance. Waterfall software development requires a clear and stable definition of the project scope, deliverables, and expectations before starting the development process. Waterfall software development can be slow, rigid, and costly, especially if changes occur during the later stages of the project. References: CISA Review Manual (Digital Version), Chapter 3: Information Systems Acquisition, Development & Implementation, Section 3.1: Project Management Practices

 Resilience is the ability of an organization to continue to operate effectively during or after a disruptive event. A business impact analysis (BIA) is a key process to identify the critical systems and processes that support the organization’s objectives and determine the impact of their disruption. Without a BIA, the organization may not be able to prioritize the recovery of the most important systems and processes, which poses the greatest risk to its resilience. The other options are not as significant as a BIA, as they relate to data quality, system monitoring, and user acceptance testing, which are important but not essential for resilience. References: CISA Review Manual (Digital Version), Domain 4: Information Systems Operations and Business Resilience, Section 4.2 Business Continuity Planning1

An IT service desk is a function that provides technical support and assistance to the users of an organization’s IT systems and services. An IT service desk typically handles issues such as software installation, hardware troubleshooting, network connectivity, password reset, system configuration,and user training. An IT service desk aims to ensure that the IT systems and services are available, reliable, secure, and efficient for the users.

One of the best indications that there are potential problems within an organization’s IT service desk function is an excessive backlog of user requests. A backlog is a list of user requests that have not been resolved or completed by the IT service desk within a specified time frame. An excessive backlog means that the IT service desk is unable to meet the demand or expectations of the users, and that the users are experiencing delays, dissatisfaction, or frustration with the IT service desk.

An excessive backlog of user requests can indicate various problems within the IT service desk function, such as:

Insufficient staff, resources, or capacity to handle the volume or complexity of user requests

Ineffective processes, procedures, or tools for managing, prioritizing, or resolving user requests

Lack of skills, knowledge, or training among the IT service desk staff to deal with different types of user requests

Poor communication, collaboration, or coordination among the IT service desk staff or with other IT functions or stakeholders

Low quality, performance, or security of the IT systems or services that cause frequent or recurring user issues

Therefore, an excessive backlog of user requests is the best indication that there are potential problems within an organization’s IT service desk function.

 The auditor’s best recommendation prior to go-live is to conduct a mock conversion test. This is because a mock conversion test can help to verify the accuracy, completeness, and validity of the data conversion process. A mock conversion test can also help to identify and resolve any issues or errors before the actual conversion takes place. A mock conversion test can also provide assurance that the converted data meets the business requirements and expectations. References:

The greatest concern for an IS auditor reviewing an online security awareness program is that metrics have not been established to assess training results. Without metrics, it is difficult to measure the effectiveness of the program and identify areas for improvement. The other findings are alsoissues that need to be addressed, but they are not as significant as the lack of metrics. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.3.11

The best way for an IS auditor to understand the software benefits to the organization would be to review the business case, which is a document that provides the justification and rationale for acquiring a software solution based on its expected costs, benefits, risks, and alignment with the organization’s goals and strategies. The business case helps to evaluate the feasibility and viability of the software acquisition and to support the decision-making process. A feasibility study is a document that analyzes the technical, operational, economic, legal, and social aspects of a software solution to determine its feasibility and suitability for the organization’s needs, but it does not necessarily provide a clear indication of the software benefits to the organization. A request for proposal (RFP) is a document that solicits proposals from potential vendors or suppliers for a software solution based on the organization’s requirements and specifications, but it does not necessarily provide a clear indication of the software benefits to the organization. The alignment with IT strategy is a factor that influences the software acquisition processand ensures that the software solution supports and enables the organization’s IT strategy, but it is not a document that can be reviewed by an IS auditor to understand the software benefits to the organization. References: CISA Review Manual(Digital Version), Chapter 3: Information Systems Acquisition, Development & Implementation, Section 3.1: Business Case Development

 Change control is the process of managing and documenting changes to an information system or its components. Change control aims to ensure that changes are authorized, tested, approved, implemented, and reviewed in a controlled and consistent manner. Change control is an essential part of ensuring the security, reliability, and quality of an information system.

One of the key elements of change control is testing and approval from quality assurance (QA). QA is the function that verifies that the changes meet the requirements and specifications, comply with the standards and policies, and do not introduce any errors or vulnerabilities. QA testing and approval provide assurance that the changes are fit for purpose, function as expected, and do not compromise the security or performance of the system.

An organization that has recently moved to an agile model for deploying custom code to its in-house accounting software system should still follow change control procedures, including QA testing and approval. Agile development methods emphasize flexibility, speed, and collaboration, but they do not eliminate the need for quality and security checks. In fact, agile methods can facilitate change control by enabling frequent and iterative testing and feedback throughout the development cycle.

However, if change control does not include testing and approval from QA, this poses a significant security concern for the organization. Without QA testing and approval, the changes may not be properly validated, verified, or evaluated before being deployed to production. This could result in introducing bugs, defects, or vulnerabilities that could affect the functionality, availability, integrity, or confidentiality of the accounting software system. For example, a change could cause data corruption, performance degradation, unauthorized access, or data leakage. These risks could have serious consequences for the organization’s financial operations, compliance obligations, reputation, or legal liabilities.

Therefore, change control that does not include testing and approval from QA is the most significant security concern to address when reviewing the procedures in place for production code deployment in an agile model.

 The most important thing to determine when conducting a post-implementation review is whether success criteria have been achieved. A post-implementation review is a process of evaluating the results and outcomes of a project or initiative after it has been completed and implemented. The success criteria are the measurable indicators that define what constitutes a successful project or initiative in terms of its objectives, benefits, quality, performance, and stakeholder satisfaction. The IS auditor should verify whether the success criteria have been achieved by comparing the actual results and outcomes with the expected or planned ones, and by assessing whether they meet or exceed the expectations and requirements of the stakeholders. The IS auditor should also identify any gaps, issues, or risks that may affect the sustainability or scalability of the project or initiative, and provide recommendations for improvement or remediation. The other options are not as important as determining whether success criteria have been achieved when conducting a post-implementation review, because they either focus on specific aspects or components of the project or initiative rather than theoverall value proposition, or they are part of the pre-implementation or implementation phases rather than the post-implementation phase. References: CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.3

The most effective method of destroying sensitive data stored on electronic media is physical destruction, which involves breaking, shredding, melting, or incinerating the media to make it unreadable and unrecoverable. Degaussing, random character overwrite, and low-level formatting are methods of sanitizing or erasing data from electronic media, but they do not guarantee complete destruction of data and may leave some traces that can be recovered by advanced techniques. Therefore, physical destruction is the most secure and reliable method of data disposal for sensitive data. References: CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.4: Data Disposal

 An IT balanced scorecard is primarily used for measuring IT strategic performance. An IT balanced scorecard is a framework that translates the IT strategy into measurable objectives, indicators, targets, and initiatives across four perspectives: financial, customer, internal process, and learning and growth. An IT balanced scorecard helps to monitor and evaluate how well the IT function is delivering value to the organization, achieving its strategic goals, and improving its capabilities and competencies. The otheroptions are not the primary uses of an IT balanced scorecard, because they either focus on specific aspects of IT rather than the overall performance, or they are not directly related to the IT strategy. References: CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.3

Substantive testing is the most important type of testing during software license audits, as it provides evidence of the accuracy and completeness of the software inventory and licensing records. Substantive testing involves examiningtransactions, balances, and other data to verify their validity, existence, accuracy, and valuation. Compliance testing, on the other hand, is more focused on assessing the adequacy and effectiveness of internal controls over software licensing, such as policies, procedures,and monitoring mechanisms. Compliance testing alone cannot provide sufficient assurance that the software license audit objectives are met, as itdoes notverify the actual software usage and compliance status. Judgmental sampling and stop-or-go sampling are methods of selecting samples for testing, not types of testing themselves. *References: According to the ISACA IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 1206 Testing, “The IS audit and assurance professional should perform sufficient testing to obtain sufficient appropriate evidence to support conclusions reached.” 1 The section also defines substantive testing as “testing performed to obtain audit evidence to detect material misstatements in transactions orbalances” and compliance testing as “testing performed to obtain audit evidence on theoperating effectiveness of controls.” 1 According to the ISACA IT Audit and Assurance Guideline G15 Software License Management, “The objective of a software license auditis to provide management with an independent assessment relating to compliance with software license agreements.” 2 The guideline also states that “substantive tests should be performed on a sample basis to verify that all software installed on devices within scope has been appropriately licensed.” 2

The IS auditor’s best course of action when preparing the final report is to include the position supported by senior management in the final engagement report. The IS auditor should communicate the audit findings and recommendations to senior management and obtain their feedback and approval before issuing the final report. If there is a disagreement between the auditee and the IS auditor regarding a recommendation for corrective action, the IS auditor should present both sides of the argument and the supporting evidence, and seek senior management’s opinion and decision. The IS auditor should respect and follow senior management’s position, and include it in the final engagement report, along with the auditee’s comments if applicable. The other options arenot the best course of action, because they either do not resolve the disagreement, do notreflect senior management’s authority, or do not report the audit results accurately and completely. References: CISA Review Manual (Digital Version)1, Chapter 2, Section 2.2.5

The answer D is correct because the number of reopened tickets is the best indicator for measuring the performance of IT help desk function. Reopened tickets are tickets that have been marked as resolved by the help desk agents, but the customers are not satisfied with the resolution and reopen them for further assistance. Reopened tickets reflect the quality and effectiveness of the help deskservice, as well as the customer satisfaction level. A high number of reopened tickets indicates that the help desk agents are not resolving the issues properly, or that they are not communicating well with the customers. This can lead to customer frustration, dissatisfaction, and churn. Therefore, minimizing the number of reopened tickets is a key goal for any help desk function.

The other options are not as good as option D. Percentage of problems raised from incidents (option A) is a metric that shows how many incidents are escalated to problems, which are more complex and require root cause analysis and long-term solutions. This metric reflects the complexity and severity of the issues faced by the customers, but it does not directly measure the performance of the help desk function. Mean time to categorize tickets (option B) is a metric that shows how long it takes for the help desk agents to assign a category to each ticket, such as technical, billing, or feedback. This metric reflects the efficiency and accuracy of the help desk agents, but it does not measure the quality or effectiveness of the resolution. Number of incidents reported (option C) is a metric that shows how many issues are reported by the customers to the help desk function. This metric reflects the demand and workload of the help desk function, but it does not measure how well the issues are resolved or how satisfied the customers are.

 Independence would be most impacted if an IS auditor were to assist with the implementation of recommended control enhancements, as this would create a conflict of interest and impair the objectivity and credibility of the IS auditor. Integrity, materiality, and accountability are important attributes of an IS auditor, but they are not directly affected by the involvement in the implementation of control enhancements. References: CISA Review Manual (Digital Version), Chapter 1: Information Systems Auditing Process, Section 1.1: IS Audit Standards, Guidelines and Codes of Ethics

 The best option to support the organization’s objectives of protecting data confidentiality while transporting data is encryption. Encryption is a process of transforming data into an unreadable form using a secret key or algorithm, so that only authorized parties can access the original data. Encryption protects the confidentiality of data in transit by preventing unauthorized interception,modification, or disclosure of the data. Encryption can also help comply with data privacy and security regulations, such as the GDPR and HIPAA.

The other options are not as effective as encryption in protecting data confidentiality while transporting data. Cryptographic hashes are mathematical functions that generate a fixed-length output from an input, but they do not encrypt the data. Hashes are used to verify the integrity and authenticity of data, but they do not prevent unauthorized access to the data. Virtual local area network (VLAN) is a logical grouping of network devices that share the same broadcast domain, but they do not encrypt the data. VLANs can improve network performance and security by isolating traffic, but they do not protect the data from being intercepted or modified by external attackers. Dedicated lines are physical connections that provide exclusive access to a network or service, but they do not encrypt the data. Dedicated lines can offer higher bandwidth and reliability, but they do not guarantee the confidentiality of the data from being compromised by physical tampering or eavesdropping.

 The auditor should be most concerned with the impact AI will have on enterprise architecture (EA) when reviewing a project to replace multiple manual data entry systems with an AI system. EA is a comprehensive framework that defines the structure, components, relationships, and principles of an organization’s IT environment. EA can help to align the IT strategy with the business strategy and ensure the coherence, consistency, and integration of the IT systems and services. Replacing manual data entry systems with an AI system may have significant implications for the EA, such aschanging the business processes, data flows, security requirements, performance standards, or governance models. The auditor should assess whether the project has considered the impact of AI on EA and whether the EA has been updated accordingly. References:

 It is acceptable for an IS auditor to rely on a third-party provider’s external audit report on service level management when the scope and methodology meet audit requirements. This means that the external audit report covers the same objectives, criteria, standards and procedures that the IS auditor would use to assess the service level management. This way, the IS auditor can avoid duplication of work and reduce audit costs and efforts. The service provider’s certification and accreditation, the report’s confirmation of service levels and the report’s release date are not sufficient to justify reliance on the external audit report. References: CISA Review Manual (Digital Version) , Chapter 2, Section 2.3.3.

Stress testing is a type of performance testing that evaluates how a system behaves under extreme load conditions, such as high user traffic, large data volumes, or limited resources. It is useful for identifying potential bottlenecks, errors, or failures that may affect the system’s functionality or availability. Stress testing during the quality assurance (QA) phase would have identified the concern of users complaining that a newly released ERP system is functioning too slowly. The other options are not as relevant for this concern, as they relate to different aspects of testing, such as regression testing (verifying that existing functionality is not affected by new changes), interface testing (verifying that the system interacts correctly with other systems or components), or integration testing (verifying that the system works as a whole after combining different modules or units). References: CISA Review Manual (Digital Version), Domain 5: Protection of Information Assets, Section 5.4 Testing Techniques1

Recovery facilities providing a redundant combination of Internet connections to the local communications loop is an example of last-mile circuit protection. Last-mile circuit protection is a type of telecommunications continuity that ensures the availability and redundancy of the final segment of the network that connects the end-user to the service provider. The local communications loop, also known as the local loop or subscriber line, is the physical link between the customer premises and the nearest central office or point of presence of the service provider. Byhavingmultiple Internet connections from different providers or technologies, such as cable, DSL, fiber, wireless, or satellite, the recoveryfacilities can avoid losing connectivity in case one of the connections fails or is disrupted by a disaster5.

 The use of control totals satisfies the control objective of processing integrity. Processing integrity refers to the accuracy, completeness, timeliness, and validity of data processing. Control totals are a method of verifying the correctness of data processing by comparing the total value or count of a batch of transactions before and after processing. For example, if a batch of 100 invoices is entered into an accounting system, the total amount and number of invoices should match before and after processing. If there is a discrepancy, it indicates an error in data entry, transmission, or processing. Control totals help to ensure that no transactions are lost, duplicated, or altered during processing.

The finding that should be of most concern to an IS auditor when evaluating information security governance within an organization is that the data center manager has final sign-off on security projects. This indicates a lack of segregation of duties and a potential conflict of interest between the operational and security roles. The data center manager may have access to sensitive information or systems that should be protected by security controls, or may influence or override security decisions that are not in the best interest of the organization. This finding also suggests that there is no clear accountability or authority for information security governance at a higher level, such as senior management or board of directors. The other findings are not as concerning as this one, although they may indicate some areas for improvement or monitoring. References:

The greatest concern to an IS auditor conducting an audit of an organization that recently experienced a ransomware attack is that backups were only performed within the local network. This means that the backups could have been encrypted or deleted by the ransomware, making it impossible to restore the data and systems without paying the ransom or losing the data. Backups are a critical part of the recovery process from a ransomware attack, and they should be performed frequently, securely, and off-site or in the cloud to ensure their availability and integrity.

The other options are not as concerning as option C, although they may also indicate some security weaknesses. Antivirus software was unable to prevent the attack even though it was properly updated, but this is not surprising given that ransomware variants are constantly evolving and antivirus software may not be able to detect them all. The most recent security patches were not tested prior to implementation, but this is a trade-off between security and availability that may be justified depending on the severity and urgency of the patches. Employees were not trained on cybersecurity policies and procedures, but this is a preventive measure that may not have prevented the attack if it was initiated by other means such as phishing or exploiting vulnerabilities.

The best testing approach to facilitate rapid identification of application interface errors is automated testing. Automated testing is the use of software tools or scripts to execute predefined test cases, compare expected and actual outcomes, and report any discrepancies. Automated testing can help to speed up the testing process, increase test coverage, reduce human errors, and improve test accuracy and consistency. Automated testing can also help to detect interface errors that may occur due to incompatible data formats, communication protocols, or system configurations. References:

 Information security policies and procedures are the foundation of an organization’s information security program. They define the roles, responsibilities, rules, and standards for protecting information assets from unauthorized access, use, disclosure, modification, or destruction. The most important factor when developing information security policies and procedures is to align them with an information security framework that provides a comprehensive and consistent approach to managing information security risks. An information security framework can also help ensure compliance with relevant regulations, inclusion of mission and objectives, and consultation with security staff. However, these factors are secondary to alignment with an information security framework. References: CISA Certification | Certified Information Systems Auditor | ISACA, CISA Review Manual (Digital Version)

 The finding that should be of greatest concern to an IS auditor assessing the effectiveness of an organization’s vulnerability scanning program is that results are not reported to individuals with authority to ensure resolution. This indicates a lack of accountability and communication for vulnerability management, which may result in unresolved or delayed remediation of identified vulnerabilities. This may expose the organization to increased risk of cyberattacks or breaches. The other findings are also concerning, but not as much as this one, because they may affect the completeness, accuracy or timeliness of the vulnerability scanning process, but not necessarily its effectiveness. References:

 The first step for the security incident response team after an IS security attack is reported is to perform a damage assessment. This involves identifying the scope, impact and root cause of the incident, as well as collecting and preserving evidence for further analysis and investigation. Reporting results to management, documenting lessons learned and prioritizing resources for corrective action are important steps, but they should be done after the damage assessment is completed. References: CISA Review Manual (DigitalVersion), Chapter 6, Section 6.31

The primary benefit of automating application testing is to provide test consistency. Automated testing can ensure that the same test cases are executed in the same manner and order every time, which can improve the reliability and accuracy of the test results. Providing more flexibility, replacing all manual test processes, and reducing the time to review code are possible benefits of automating application testing, but they are not the primary benefit. References:

Controls related to authorized modifications to production programs are best tested by tracing modifications from the original request for change forward to the executable program, as this ensures that the change management process was followed and that the modifications were approved, documented, tested, and implemented correctly. Tracing modifications from the executable program back to the original request for change may not reveal any unauthorized or undocumented changes that occurred during the process. Testing only the authorizations to implement the new program or reviewing only the actual lines of source code changed in the program are not sufficient to test the controls related to authorized modifications, as they do not cover the entire change management process. References: CISA Review Manual (Digital Version), Chapter 4: Information Systems Operations, Maintenance and Service Management, Section 4.2: Change Management

The best recommendation is to align the IT strategy with the business objectives. This will ensure that the IT projects and initiatives are consistent with the organization’s vision, mission, and goals. IT strategy should be derived from and support the business strategy, not the other way around. By aligning the IT strategy with the business objectives, the organization can achieve better value, performance, and alignment from its IT investments.

Reviewing priorities in the IT portfolio (option B) is not the best recommendation, as it does not address the root cause of the misalignment between the IT strategy and the IT portfolio. The IT portfolio should reflect the IT strategy, which in turn should reflect the business objectives. Simply changing the priorities in the IT portfolio without aligning the IT strategy with the business objectives may result in suboptimal or conflicting outcomes.

Changing the IT strategy to focus on operational excellence (option C) is also not the best recommendation, as it may not be aligned with the business objectives. The organization’s IT strategy should be based on its competitive advantage, market position, customer needs, and industry trends. If the organization’s business strategy is heavily focused on research and development, then changing the IT strategy to focus on operational excellence may not be appropriate or beneficial.

Aligning the IT portfolio with the IT strategy (option D) is also not the best recommendation, as it does not address the misalignment between the IT strategy and the business objectives. Aligning the IT portfolio with the IT strategy may improve the coherence and consistency of the IT projects, but it may not ensure that they are aligned with the organization’s vision, mission, and goals.

Therefore, option A is the correct answer.

The greatest indicator that the cybersecurity policy may need to be revised is a significant increase in approved exceptions. This implies that the policy is not aligned with the current business needs and risks, and that it may be too restrictive or outdated. The other options are not necessarily indicators of a need for policy revision, as they may be due to other factors such as changes in the externalenvironment, audit scope or methodology. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.21

The best solution for ensuring secure remote access to corporate resources is to use a virtual private network (VPN), as this creates an encrypted tunnel between the user’s device and the corporate network, preventing unauthorized interception or modification of data in transit. Additional firewall rules may help to restrict access to certain ports or protocols, but they do not provide encryption or authentication. Multi-factor authentication may help to verify the identity of the user, but it does not protect the data in transit. Virtual desktop may help to provide a consistent user interface and access to applications, but it does not ensure the security of thecommunication channel. References: CISA Review Manual (Digital Version), Chapter 5:Protection of Information Assets, Section 5.2: Network Security Devices and Technologies

The best situation that justifies the use of a smaller sample size when testing the accuracy of transaction data is B. It is expected that the population is error-free. The sample size is the number of items selected from the population for testing. The sample size depends on various factors, such as the level of confidence, the tolerable error rate, the expected error rate, and the variability of the population. A smaller sample size means that fewer items are tested, which reduces the cost and time of testing, but also increases the sampling risk (the risk that the sample is not representative of the population).

One of the factors that affects the sample size is the expected error rate, which is the auditor’s best estimate of the proportion of errors in the population before testing. A higher expected error rate means that more errors are likely to be found in the population, which requires a larger sample size to provide sufficient evidence for the auditor’s conclusion. A lower expected error rate means that fewer errors are likely to be found in the population, which allows a smaller sample size to provide sufficient evidence for the auditor’s conclusion. Therefore, if it is expected that the population is error-free (i.e., the expected error rate is zero or very low), a smaller sample size can be justified.

The other situations do not justify the use of a smaller sample size when testing the accuracy of transaction data. A. The IS audit staff has a high level of experience. The IS audit staff’s level of experience does not affect the sample size, but rather their ability to design and execute the sampling procedures and evaluate the results. The IS audit staff’s level of experience may affect their judgment in selecting and applying sampling methods, but it does not change the statistical or mathematical principles that determine the sample size. B. Proper segregation of duties is in place. Proper segregation of duties is an internal control that helps prevent or detect errors or fraud in transaction processing, but it does not affect the sample size. The sample size is based on the characteristics of the population and the objectives of testing, not on the controls in place. Proper segregation of duties may reduce the likelihood or impact of errors or fraud in transaction processing, but it does not eliminate them completely. Therefore, proper segregation of duties does not justify a smaller sample size when testing the accuracy of transaction data. C. The data can be directly changed by users. The data’s ability to be directly changed by users does not justify a smaller sample size, but rather a larger one. The data’s ability to be directly changed by users increases the risk of errors or fraud in transaction processing, which requires a larger sample size to provide sufficient evidence for the auditor’s conclusion. The data’s ability to be directly changed by users also increases the variability of the population, which affects the sample size.

This means that the IT investments are aligned with the strategic goals and priorities of the organization, and that they deliver value and benefits to the business. Mapping IT investments to specific business objectives can help ensure that the IT investments are relevant, justified, and measurable, and that they support the organization’s mission and vision.

IT investments are implemented and monitored following a system development life cycle (SDLC) is an indication of effective IT project management, but not necessarily of effective IT investment management. The SDLC is a framework that guides the development and implementation of IT systemsand applications, but it does not address the alignment, justification, or measurement of the IT investments.

Key performance indicators (KPIs) are defined for each business requiring IT investment is an indication of effective IT performance management, but not necessarily of effective IT investment management. KPIs are metrics that measure the outcomes and results of IT activities and processes, but they do not address the alignment, justification, or value of the IT investments.

The IT investment budget is significantly below industry benchmarks is not an indication of effective IT investment management, but rather of low IT spending. The IT investment budget should be based on the organization’s needs and capabilities, and not on external comparisons. A low IT investment budget may indicate that the organization is underinvesting in IT, which could limit its potential for growth and innovation.

The primary purpose of requiring source code escrow in a contractual agreement is to ensure the source code is available. Source code escrow is a service that involves depositing the source code of a software or system with a third-party agent or escrow provider, who can release it to a designated beneficiary under specific conditions, such as bankruptcy, termination, or breach of contract by the software vendor or developer. Source code escrow can help to protect the interests and rights of the software user or licensee, who may need access to the source code for maintenance, modification, enhancement, or troubleshooting purposes. The IS auditor should verify that the contractual agreement specifies the terms and conditions for source code escrow, such as the escrow agent,the escrow fees, the deposit frequency and format,the release events and procedures, and the verification and audit requirements. References: CISA ReviewManual (Digital Version)1, Chapter 3, Section 3.2.2

The first step to successfully implement a corporate data classification program is to approve a data classification policy. A data classification policy is a document that defines the objectives, scope, principles, roles, responsibilities, and procedures for classifying data based on its sensitivity and value to the organization. A data classification policy is essential for establishing a common understanding and a consistent approach for data classification across the organization, as well as for ensuring compliance with relevant regulatory and contractual requirements.

Selecting a data loss prevention (DLP) product (option B) is not the first step to implement a data classification program, as it is a technical solution that supports the enforcement of the data classification policy, not the definition of it. A DLP product can help prevent unauthorized access, use, or disclosure of sensitive data by monitoring, detecting, and blocking data flows that violate the data classification policy. However, before selecting a DLP product, the organization needs to have a clear and approved data classification policy that specifies the criteria and rules for data classification.

Confirming that adequate resources are available for the project (option C) is also not the first step to implement a data classification program, as it is a project management activity that ensures the feasibility and sustainability of the project, not the design of it. Confirming that adequate resources are available for the project involves estimating and securing the necessary budget, staff, time, and tools for implementing and maintaining the data classification program. However, before confirming that adequate resources are available for the project, the organization needs to have a clear and approved data classification policy that defines the scope and objectives of the project.

Checking for the required regulatory requirements (option D) is also not the first step to implement a data classification program, as it is an input to the development of the data classification policy, not an output of it. Checking for the required regulatory requirements involves identifying and analyzing the applicable laws, regulations, standards, and contracts that govern the protection and handling of sensitive data. However, checking for the required regulatory requirements is not enough to implement a data classification program; the organization also needs to have a clear and approved data classification policy that incorporates and complies with those requirements.

Therefore, option A is the correct answer.

 The greatest benefit of adopting an international IT governance framework rather than establishing a new framework based on the actual situation of a specific organization is wide acceptance by different business and support units with IT governance objectives. An international IT governance framework, such as COBIT, provides a common language and understanding for IT governance among various stakeholders, such as management, users, auditors and regulators. This facilitates alignment, communication and collaboration among them. Readily available resources, comprehensive coverage and fewer resources expended are also benefits of adopting an international IT governance framework, but they are not the greatest benefit. References: CISA Review Manual (Digital Version) , Chapter 1, Section 1.3.1.

The lack of system documentation should be of most concern to an IS auditor reviewing the information systems acquisition, development, and implementation process. This is because system documentation is a vital source of information that describes the system’s purpose, functionality, design, architecture, testing, deployment, operation, and maintenance. System documentation helps the IS auditor to understand and evaluate the system’s quality, performance, security, compliance, and alignment with the business requirements and objectives. Without system documentation, the IS auditor may not be able to perform a thorough and effective audit of the system, aswell as identify any issues or risks that may affect the system’s reliability or integrity12.

Data owners are not trained on the use of data conversion tools is not the most concerning issue, although it may indicate a lack of user readiness or competence for the system implementation. Data conversion tools are software applications that help users to transform data from one format or structure to another, such as from legacy systems to new systems. Data owners are users who have the responsibility and authority to manage and control the data within their domain. Data owners should be trained on how to use data conversion tools to ensure that the data is accurately and securely transferred to the new system, as well as to avoid any data loss, corruption, or inconsistency. However, data owners are not the only users who need training for the system implementation, and data conversion tools are not the only tools that need training34.

A post-implementation lessons-learned exercise was not conducted is not the most concerning issue, although it may indicate a lack of continuous improvement or learning culture for the system development and implementation process. A post-implementation lessons-learned exercise is a meeting or a session that takes place after the completion of a system implementation project, where the project team and stakeholders discuss and document the successes and failures of the project, as well as identify any best practices or areas for improvement for future projects. Apost-implementation lessons-learned exercise can help to enhance the project management skills, knowledge, and performance of the project team and stakeholders, as well as to avoid repeating the same mistakes or problems in future projects56.

System deployment is routinely performed by contractors is not the most concerning issue, although it may pose some challenges or risks for the system implementation process. System deployment is the final stage of the system development life cycle (SDLC), where the system is installed and configured on the target environment and made available for use by end-users. System deployment can be performed by internal staff or external contractors, depending on the availability, expertise, and cost of resources. System deployment by contractors may offer some benefits such as faster delivery, lower cost, or higher quality than internal staff. However, system deployment by contractors mayalso introduce some risks such as loss of control, dependency, or security breaches over the system implementation process

The best indication to an IS auditor that management’s post-implementation review was effective is that lessons learned were documented and applied, as this shows that the management has identified and addressed the issues and gaps that arose during the implementation, and has improved the processes and practices for future projects. Business and IT stakeholders participating in the post-implementation review is a good practice, but it does not guarantee that the review was effective or that the outcomes were implemented. Post-implementation review being a formal phase in the system development life cycle (SDLC) is a requirement, but it does not ensure that the review was effective or that the outcomes were implemented. Internal audit follow-up being completed without any findings is a desirable result, but it does not indicate that the management’s post-implementation review was effectiveorthat the outcomes were implemented. References: CISA Review Manual (Digital Version), Chapter 3: Information Systems Acquisition, Development andImplementation, Section 3.2: Project Management Practices1

A balanced scorecard is a framework that translates the IT strategy into measurable objectives, indicators, targets, and initiatives across four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard helps to monitor and evaluate how well the IT function is delivering value to the organization, achieving its strategic goals, and improving its capabilities and competencies. The other options are not the primary uses of a balanced scorecard, because they either focus on specific aspects of IT rather than the overall performance, or they are not directly related to the IT strategy.

A vendor requires privileged access to a key business application. The best recommendation to reduce the risk of data leakage is to implement real-time activity monitoring for privileged roles. This is because real-time activity monitoring can provide visibility and accountability for the actions performed by the vendor with privileged access, such as creating, modifying, deleting, or copying data. Real-time activity monitoring can also enable timely detection and response to any unauthorized or suspicious activities that may indicate data leakage. Including the right-to-audit in the vendor contract is a good practice, but it may not be sufficient to prevent or detect data leakage in a timely manner, as audits are usually performed periodically or on-demand. Performing a review of privileged roles and responsibilities is also a good practice, but it may not address the specific risk of data leakage by the vendor with privileged access. Requiring the vendor to implement job rotation for privileged roles may reduce the risk of collusion or fraud, but it may not prevent or detect data leakage by any individual with privileged access. References: CISA Review Manual (Digital Version), [ISACA Privacy Principles and Program Management Guide]

The answer B is correct because Software as a Service (SaaS) provider is the most efficient solution for a multi-location healthcare organization that wants to be able to access patient data wherever patients present themselves for care. SaaS is a cloud computing model that allows users to access software applications over the internet, without having to install, maintain, or update them on their own devices or servers. SaaS providers host and manage the software applications and the underlying infrastructure, and handle any issues such as security, availability, and performance.

SaaS can offer several benefits for a multi-location healthcare organization, such as:

Accessibility: SaaS applications can be accessed from any device and location that has an internet connection, which enables the healthcare organization to access patient data across different facilities and regions, and provide seamless and coordinated care to the patients.

Scalability: SaaS applications can scale up or down according to the demand and usage of the healthcare organization, which allows the organization to accommodate fluctuations in patient volume, data volume, or service requirements.

Cost-effectiveness: SaaS applications are usually offered on a subscription or pay-per-use basis, which reduces the upfront and ongoing costs of purchasing, installing, and maintaining software licenses, hardware, and IT staff.

Security: SaaS providers are responsible for ensuring the security and privacy of the software applications and the data they store, which can help the healthcare organization comply with the relevant regulations and standards, such as HIPAA (Health Insurance Portability and Accountability Act) or GDPR (General Data Protection Regulation).

Some examples of SaaS providers that offer solutions for healthcare organizations are:

Epic: Epic is a leading provider of electronic health record (EHR) systems that enable healthcare organizations to store, manage, and share patient data across different settingsand specialties. Epic also offers cloud-based solutions that allow healthcare organizations to access Epic’s software applications over the internet, without having to host them on their own servers.

Salesforce Health Cloud: Salesforce Health Cloud is a cloud-based platform that helps healthcare organizations connect with patients, providers, payers, and partners. Salesforce Health Cloud enables healthcare organizations to manage patient relationships, coordinate care teams, engage patients through personalized journeys, and leverage data and analytics to improve outcomes and efficiency.

DocuSign: DocuSign is a cloud-based platform that enables users to sign, send, and manage documents electronically. DocuSign can help healthcare organizations streamline workflows, reduce errors, and enhance compliance by automating the process of obtaining signatures for consent forms, contracts, prescriptions, referrals, and other documents.

The other options are not as efficient as option B. Infrastructure as a Service (IaaS) provider (option A) is a cloud computing model that provides users with access to computing resources such as servers, storage, network, and operating systems over the internet. IaaS can offer some benefits such as flexibility, scalability, and cost-effectiveness for a multi-location healthcare organization, but it also requires more technical expertise and management from the organization than SaaS. The organization would still need to install, configure, update, and secure the software applications that run on the IaaS infrastructure. Network segmentation (option C) is a technique that divides a network into smaller subnetworks based on criteria such as function, location, or security level. Network segmentation can improve the performance, security, and manageability of a network by reducing congestion, isolating threats, and enforcing policies. However, network segmentation alone does not enable a multi-location healthcare organization to access patient data wherever patients present themselves for care. The organization would still need a software solution that can store, manage, and share patient data across different segments of the network. Dynamic localization (option D) is a process that adapts the content and functionality of a software application to suit the preferences and needs of users in different locations or regions. Dynamic localization can enhance the user experience and satisfaction by providing relevant information in local languages, currencies, formats, and regulations. However, dynamic localization does not address the core issue of accessing patient data wherever patients present themselves for care. The organization would still need a software solution that can store, manage, and share patient data across different locations or regions.

Imaging the affected system is the best way to protect evidence in a forensic investigation, because it creates a bit-by-bit copy of the original data that can be analyzed without altering or compromising the original source. Imaging preserves the integrity and authenticity of the evidence and allows for verification and validation of the results34. Powering down or rebooting the affected system can cause data loss or corruption, while protecting the hardware does not prevent unauthorized access or tampering with the software or data. References: 3: CISA Review Manual (Digital Version), Chapter 6, Section 6.4.1 4: CISA Online Review Course, Module 6, Lesson 4

 The most important thing to assess when conducting a business impact analysis (BIA) is the completeness of critical asset inventory. This is because the critical asset inventory is the basis for identifying and prioritizing the business processes, functions, and resources that are essential for thecontinuity of operations. The critical asset inventory should include both tangible and intangible assets, such as hardware, software, data, personnel, facilities, contracts, and reputation. The critical asset inventory should also be updated regularly to reflect any changes in the business environment or needs. References:

The area that is most likely to be overlooked when implementing a new data classification process is end-user computing (EUC) systems. EUC systems are applications or tools that are developed or customized by end users, often without formal IT involvement or approval. EUC systems may contain sensitive or confidential data that need to be classified and protected according to the organization’s policies and standards. However, EUC systems may not be subject to the same controls, oversight, or documentation as formal IT systems, and may not be included in the scope of the data classification process. Therefore, EUC systems pose a significant risk of data leakage, unauthorized access, or noncompliance. The other areas (B, C and D) are less likely to be overlooked, as they are more visible and manageable by the IT department or the data owners. References: IS Audit and Assurance Guideline 2202: Evidence Collection Techniques, CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.2: Data Classification

The auditor’s best course of action is to document the finding and explain the risk of having administrator accounts with inappropriate security settings. This is because the auditor’s role is to identify and report the issues, not to fix them or request others to fix them. The auditor should also communicate the impact of the finding, such as the possibility of unauthorized access, data tampering, or denial of service attacks. The auditor should not assume the responsibility of the IT manager or the DBA, who are in charge of changing the security parameters or disabling the accounts. References:

Following a breach, the maximum amount of time before customers must be notified that their personal information may have been compromised depends on the industry regulations that apply to the organization. Different industries and jurisdictions may have different legal and regulatory requirements for breach notification, such as the General Data Protection Regulation (GDPR) in the European Union, the Health Insurance Portability and Accountability Act (HIPAA) in the United States, or the Personal Information Protection and Electronic Documents Act (PIPEDA) in Canada. Industry standards, incident response plans, and information security policies are not as authoritative as industry regulations in determining the breach notification time frame. References: CISA Review Manual (Digital Version), [ISACA Privacy Principles and Program Management Guide]

Full disk encryption (FDE) is a means of protecting information by encrypting all of thedata on a disk, including temporary files, programs, and system files1. FDE is best suited for addressing the risk scenario of physical theft of media on which information is stored, as it prevents unauthorized access to the data even if the device is lost or stolen2. FDE does not prevent data leakage as a result of employees leaving to work for competitors, as they may still have access to the data while using the device or copy the data to another device before leaving. FDE does not prevent noncompliance fines related to storage of regulated information, as it does not ensure that the data is stored in accordance with the applicable laws and regulations. FDE does not prevent unauthorized logical access to information through an application interface, as it does not control the access rights and permissions of users and applications. *References: According to the ISACA IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 2402 Planning, “The IS audit and assurance professional should identify and assess risk relevant to the area under review.” 3 Oneof the risk factors to consider is “the sensitivity of information processed, stored or transmitted by the system” 3. FDE is one of the possible controls to mitigate the risk of unauthorized disclosure of sensitive information due to physical theft of media.
