Which of the following is a web application control that should be put into place to prevent exploitation of Operating System (OS) bugs?
Check arguments in function calls
Test for the security patch level of the environment
Include logging functions
Digitally sign each application module
Testing for the security patch level of the environment is the web application control that should be put into place to prevent exploitation of Operating System (OS) bugs. OS bugs are errors or defects in the code or logic of the OS that can cause the OS to malfunction or behave unexpectedly. OS bugs can be exploited by attackers to gain unauthorized access, disrupt business operations, or steal or leak sensitive data. Testing for the security patch level of the environment is the web application control that should be put into place to prevent exploitation of OS bugs, because it can provide several benefits, such as:
Detecting and resolving any vulnerabilities or issues caused by the OS bugs by applying the latest security patches or updates from the OS developers or vendors
Enhancing the security and performance of the web applications by using the most secure and efficient version of the OS that supports the web applications
Increasing the compliance and alignment of the web applications with the security policies and regulations that are applicable to the web applications
Improving the compatibility and interoperability of the web applications with the other systems or platforms that interact with the web applications
The other options are not the web application controls that should be put into place to prevent exploitation of OS bugs, but rather web application controls that can prevent or mitigate other types of web application attacks or issues. Checking arguments in function calls is a web application control that can prevent or mitigate buffer overflow attacks, which are attacks that exploit the vulnerability of the web application code that does not properly check the size or length of the input data that is passed to a function or a variable, and overwrite the adjacent memory locations with malicious code or data. Including logging functions is a web application control that can prevent or mitigate unauthorized access or modification attacks, which are attacks that exploit the lack of or weak authentication or authorization mechanisms of the web applications, and access or modify the web application data or functionality without proper permission or verification. Digitally signing each application module is a web application control that can prevent or mitigate code injection or tampering attacks, which are attacks that exploit the vulnerability of the web application code that does not properly validate or sanitize the input data that is executed or interpreted by the web application, and inject or modify the web application code with malicious code or data.
When in the Software Development Life Cycle (SDLC) MUST software security functional requirements be defined?
After the system preliminary design has been developed and the data security categorization has been performed
After the vulnerability analysis has been performed and before the system detailed design begins
After the system preliminary design has been developed and before the data security categorization begins
After the business functional analysis and the data security categorization have been performed
Software security functional requirements must be defined after the business functional analysis and the data security categorization have been performed in the Software Development Life Cycle (SDLC). The SDLC is a process that involves planning, designing, developing, testing, deploying, operating, and maintaining a system, using various models and methodologies, such as waterfall, spiral, agile, or DevSecOps. The SDLC can be divided into several phases, each with its own objectives and activities, such as:
System initiation: This phase involves defining the scope, purpose, and objectives of the system, identifying the stakeholders and their needs and expectations, and establishing the project plan and budget.
System acquisition and development: This phase involves designing the architecture and components of the system, selecting and procuring the hardware and software resources, developing and coding the system functionality and features, and integrating and testing the system modules and interfaces.
System implementation: This phase involves deploying and installing the system to the production environment, migrating and converting the data and applications from the legacy system, training and educating the users and staff on the system operation and maintenance, and evaluating and validating the system performance and effectiveness.
System operations and maintenance: This phase involves operating and monitoring the system functionality and availability, maintaining and updating the system hardware and software, resolving and troubleshooting any issues or problems, and enhancing and optimizing the system features and capabilities.
Software security functional requirements are the specific and measurable security features and capabilities that the system must provide to meet the security objectives and requirements. Software security functional requirements are derived from the business functional analysis and the data security categorization, which are two tasks that are performed in the system initiation phase of the SDLC. The business functional analysis is the process of identifying and documenting the business functions and processes that the system must support and enable, such as the inputs, outputs, workflows, and tasks. The data security categorization is the process of determining the security level and impact of the system and its data, based on the confidentiality, integrity, and availability criteria, and applying the appropriate security controls and measures. Software security functional requirements must be defined after the business functional analysis and the data security categorization have been performed, because they can ensure that the system design and development are consistent and compliant with the security objectives and requirements, and that the system security is aligned and integrated with the business functions and processes.
The other options are not the phases of the SDLC when the software security functional requirements must be defined, but rather phases that involve other tasks or activities related to the system design and development. After the system preliminary design has been developed and the data security categorization has been performed is not the phase when the software security functional requirements must be defined, but rather the phase when the system architecture and components are designed, based on the system scope and objectives, and the data security categorization is verified and validated. After the vulnerability analysis has been performed and before the system detailed design begins is not the phase when the software security functional requirements must be defined, but rather the phase when the system design and components are evaluated and tested for the security effectiveness and compliance, and the system detailed design is developed, based on the system architecture and components. After the system preliminary design has been developed and before the data security categorization begins is not the phase when the software security functional requirements must be defined, but rather the phase when the system architecture and components are designed, based on the system scope and objectives, and the data security categorization is initiated and planned.
Which of the following is the PRIMARY risk with using open source software in a commercial software construction?
Lack of software documentation
License agreements requiring release of modified code
Expiration of the license agreement
Costs associated with support of the software
The primary risk with using open source software in a commercial software construction is license agreements requiring release of modified code. Open source software is software that uses publicly available source code, which can be seen, modified, and distributed by anyone. Open source software has some advantages, such as being affordable and flexible, but it also has some disadvantages, such as being potentially insecure or unsupported.
One of the main disadvantages of using open source software in a commercial software construction is the license agreements that govern the use and distribution of the open source software. License agreements are legal contracts that specify the rights and obligations of the parties involved in the software, such as the original authors, the developers, and the users. License agreements can vary in terms of their terms and conditions, such as the scope, the duration, or the fees of the software.
Some of the common types of license agreements for open source software are:
Permissive licenses: license agreements that allow the developers and users to freely use, modify, and distribute the open source software, with minimal or no restrictions. Examples of permissive licenses are the MIT License, the Apache License, or the BSD License.
Copyleft licenses: license agreements that require the developers and users to share and distribute the open source software and any modifications or derivatives of it, under the same or compatible license terms and conditions. Examples of copyleft licenses are the GNU General Public License (GPL), the GNU Lesser General Public License (LGPL), or the Mozilla Public License (MPL).
Mixed licenses: license agreements that combine the elements of permissive and copyleft licenses, and may apply different license terms and conditions to different parts or components of the open source software. Examples of mixed licenses are the Eclipse Public License (EPL), the Common Development and Distribution License (CDDL), or the GNU Affero General Public License (AGPL).
The primary risk with using open source software in a commercial software construction is license agreements requiring release of modified code, which are usually associated with copyleft licenses. This means that if a commercial software construction uses or incorporates open source software that is licensed under a copyleft license, then it must also release its own source code and any modifications or derivatives of it, under the same or compatible copyleft license. This can pose a significant risk for the commercial software construction, as it may lose its competitive advantage, intellectual property, or revenue, by disclosing its source code and allowing others to use, modify, or distribute it.
The other options are not the primary risks with using open source software in a commercial software construction, but rather secondary or minor risks that may or may not apply to the open source software. Lack of software documentation is a secondary risk with using open source software in a commercial software construction, as it may affect the quality, usability, or maintainability of the open source software, but it does not necessarily affect the rights or obligations of the commercial software construction. Expiration of the license agreement is a minor risk with using open source software in a commercial software construction, as it may affect the availability or continuity of the open source software, but it is unlikely to happen, as most open source software licenses are perpetual or indefinite. Costs associated with support of the software is a secondary risk with using open source software in a commercial software construction, as it may affect the reliability, security, or performance of the open source software, but it can be mitigated or avoided by choosing the open source software that has adequate or alternative support options.
A Java program is being developed to read a file from computer A and write it to computer B, using a third computer C. The program is not working as expected. What is the MOST probable security feature of Java preventing the program from operating as intended?
Least privilege
Privilege escalation
Defense in depth
Privilege bracketing
The most probable security feature of Java preventing the program from operating as intended is least privilege. Least privilege is a principle that states that a subject (such as a user, a process, or a program) should only have the minimum amount of access or permissions that are necessary to perform its function or task. Least privilege can help to reduce the attack surface and the potential damage of a system or network, by limiting the exposure and impact of a subject in case of a compromise or misuse.
Java implements the principle of least privilege through its security model, which consists of several components, such as:
The Java Virtual Machine (JVM): a software layer that executes the Java bytecode and provides an abstraction from the underlying hardware and operating system. The JVM enforces the security rules and restrictions on the Java programs, such as the memory protection, the bytecode verification, and the exception handling.
The Java Security Manager: a class that defines and controls the security policy and permissions for the Java programs. The Java Security Manager can be configured and customized by the system administrator or the user, and can grant or deny the access or actions of the Java programs, such as the file I/O, the network communication, or the system properties.
The Java Security Policy: a file that specifies the security permissions for the Java programs, based on the code source and the code signer. The Java Security Policy can be defined and modified by the system administrator or the user, and can assign different levels of permissions to different Java programs, such as the trusted or the untrusted ones.
The Java Security Sandbox: a mechanism that isolates and restricts the Java programs that are downloaded or executed from untrusted sources, such as the web or the network. The Java Security Sandbox applies the default or the minimal security permissions to the untrusted Java programs, and prevents them from accessing or modifying the local resources or data, such as the files, the databases, or the registry.
In this question, the Java program is being developed to read a file from computer A and write it to computer B, using a third computer C. This means that the Java program needs to have the permissions to perform the file I/O and the network communication operations, which are considered as sensitive or risky actions by the Java security model. However, if the Java program is running on computer C with the default or the minimal security permissions, such as in the Java Security Sandbox, then it will not be able to perform these operations, and the program will not work as expected. Therefore, the most probable security feature of Java preventing the program from operating as intended is least privilege, which limits the access or permissions of the Java program based on its source, signer, or policy.
The other options are not the security features of Java preventing the program from operating as intended, but rather concepts or techniques that are related to security in general or in other contexts. Privilege escalation is a technique that allows a subject to gain higher or unauthorized access or permissions than what it is supposed to have, by exploiting a vulnerability or a flaw in a system or network. Privilege escalation can help an attacker to perform malicious actions or to access sensitive resources or data, by bypassing the security controls or restrictions. Defense in depth is a concept that states that a system or network should have multiple layers or levels of security, to provide redundancy and resilience in case of a breach or an attack. Defense in depth can help to protect a system or network from various threats and risks, by using different types of security measures and controls, such as the physical, the technical, or the administrative ones. Privilege bracketing is a technique that allows a subject to temporarily elevate or lower its access or permissions, to perform a specific function or task, and then return to its original or normal level. Privilege bracketing can help to reduce the exposure and impact of a subject, by minimizing the time and scope of its higher or lower access or permissions.
The configuration management and control task of the certification and accreditation process is incorporated in which phase of the System Development Life Cycle (SDLC)?
System acquisition and development
System operations and maintenance
System initiation
System implementation
The configuration management and control task of the certification and accreditation process is incorporated in the system acquisition and development phase of the System Development Life Cycle (SDLC). The SDLC is a process that involves planning, designing, developing, testing, deploying, operating, and maintaining a system, using various models and methodologies, such as waterfall, spiral, agile, or DevSecOps. The SDLC can be divided into several phases, each with its own objectives and activities, such as:
System initiation: This phase involves defining the scope, purpose, and objectives of the system, identifying the stakeholders and their needs and expectations, and establishing the project plan and budget.
System acquisition and development: This phase involves designing the architecture and components of the system, selecting and procuring the hardware and software resources, developing and coding the system functionality and features, and integrating and testing the system modules and interfaces.
System implementation: This phase involves deploying and installing the system to the production environment, migrating and converting the data and applications from the legacy system, training and educating the users and staff on the system operation and maintenance, and evaluating and validating the system performance and effectiveness.
System operations and maintenance: This phase involves operating and monitoring the system functionality and availability, maintaining and updating the system hardware and software, resolving and troubleshooting any issues or problems, and enhancing and optimizing the system features and capabilities.
The certification and accreditation process is a process that involves assessing and verifying the security and compliance of a system, and authorizing and approving the system operation and maintenance, using various standards and frameworks, such as NIST SP 800-37 or ISO/IEC 27001. The certification and accreditation process can be divided into several tasks, each with its own objectives and activities, such as:
Security categorization: This task involves determining the security level and impact of the system and its data, based on the confidentiality, integrity, and availability criteria, and applying the appropriate security controls and measures.
Security planning: This task involves defining the security objectives and requirements of the system, identifying the roles and responsibilities of the security stakeholders, and developing and documenting the security plan and policy.
Security implementation: This task involves implementing and enforcing the security controls and measures for the system, according to the security plan and policy, and ensuring the security functionality and compatibility of the system.
Security assessment: This task involves evaluating and testing the security effectiveness and compliance of the system, using various techniques and tools, such as audits, reviews, scans, or penetration tests, and identifying and reporting any security weaknesses or gaps.
Security authorization: This task involves reviewing and approving the security assessment results and recommendations, and granting or denying the authorization for the system operation and maintenance, based on the risk and impact analysis and the security objectives and requirements.
Security monitoring: This task involves monitoring and updating the security status and activities of the system, using various methods and tools, such as logs, alerts, or reports, and addressing and resolving any security issues or changes.
The configuration management and control task of the certification and accreditation process is incorporated in the system acquisition and development phase of the SDLC, because it can ensure that the system design and development are consistent and compliant with the security objectives and requirements, and that the system changes are controlled and documented. Configuration management and control is a process that involves establishing and maintaining the baseline and the inventory of the system components and resources, such as hardware, software, data, or documentation, and tracking and recording any modifications or updates to the system components and resources, using various techniques and tools, such as version control, change control, or configuration audits. Configuration management and control can provide several benefits, such as:
Improving the quality and security of the system design and development by identifying and addressing any errors or inconsistencies
Enhancing the performance and efficiency of the system design and development by optimizing the use and allocation of the system components and resources
Increasing the compliance and alignment of the system design and development with the security objectives and requirements by applying and enforcing the security controls and measures
Facilitating the monitoring and improvement of the system design and development by providing the evidence and information for the security assessment and authorization
The other options are not the phases of the SDLC that incorporate the configuration management and control task of the certification and accreditation process, but rather phases that involve other tasks of the certification and accreditation process. System operations and maintenance is a phase of the SDLC that incorporates the security monitoring task of the certification and accreditation process, because it can ensure that the system operation and maintenance are consistent and compliant with the security objectives and requirements, and that the system security is updated and improved. System initiation is a phase of the SDLC that incorporates the security categorization and security planning tasks of the certification and accreditation process, because it can ensure that the system scope and objectives are defined and aligned with the security objectives and requirements, and that the security plan and policy are developed and documented. System implementation is a phase of the SDLC that incorporates the security assessment and security authorization tasks of the certification and accreditation process, because it can ensure that the system deployment and installation are evaluated and verified for the security effectiveness and compliance, and that the system operation and maintenance are authorized and approved based on the risk and impact analysis and the security objectives and requirements.
What is the BEST approach to addressing security issues in legacy web applications?
Debug the security issues
Migrate to newer, supported applications where possible
Conduct a security assessment
Protect the legacy application with a web application firewall
Migrating to newer, supported applications where possible is the best approach to addressing security issues in legacy web applications. Legacy web applications are web applications that are outdated, unsupported, or incompatible with the current technologies and standards. Legacy web applications may have various security issues, such as:
Vulnerabilities and bugs that are not fixed or patched by the developers or vendors
Weak or obsolete encryption and authentication mechanisms that are easily broken or bypassed by attackers
Lack of compliance with the security policies and regulations that are applicable to the web applications
Incompatibility or interoperability issues with the newer web browsers, operating systems, or platforms that are used by the users or clients
Migrating to newer, supported applications where possible is the best approach to addressing security issues in legacy web applications, because it can provide several benefits, such as:
Enhancing the security and performance of the web applications by using the latest technologies and standards that are more secure and efficient
Reducing the risk and impact of the web application attacks by eliminating or minimizing the vulnerabilities and bugs that are present in the legacy web applications
Increasing the compliance and alignment of the web applications with the security policies and regulations that are applicable to the web applications
Improving the compatibility and interoperability of the web applications with the newer web browsers, operating systems, or platforms that are used by the users or clients
The other options are not the best approaches to addressing security issues in legacy web applications, but rather approaches that can mitigate or remediate the security issues, but not eliminate or prevent them. Debugging the security issues is an approach that can mitigate the security issues in legacy web applications, but not the best approach, because it involves identifying and fixing the errors or defects in the code or logic of the web applications, which may be difficult or impossible to do for the legacy web applications that are outdated or unsupported. Conducting a security assessment is an approach that can remediate the security issues in legacy web applications, but not the best approach, because it involves evaluating and testing the security effectiveness and compliance of the web applications, using various techniques and tools, such as audits, reviews, scans, or penetration tests, and identifying and reporting any security weaknesses or gaps, which may not be sufficient or feasible to do for the legacy web applications that are incompatible or obsolete. Protecting the legacy application with a web application firewall is an approach that can mitigate the security issues in legacy web applications, but not the best approach, because it involves deploying and configuring a web application firewall, which is a security device or software that monitors and filters the web traffic between the web applications and the users or clients, and blocks or allows the web requests or responses based on the predefined rules or policies, which may not be effective or efficient to do for the legacy web applications that have weak or outdated encryption or authentication mechanisms.
Which of the following is the BEST method to prevent malware from being introduced into a production environment?
Purchase software from a limited list of retailers
Verify the hash key or certificate key of all updates
Do not permit programs, patches, or updates from the Internet
Test all new software in a segregated environment
Testing all new software in a segregated environment is the best method to prevent malware from being introduced into a production environment. Malware is any malicious software that can harm or compromise the security, availability, integrity, or confidentiality of a system or data. Malware can be introduced into a production environment through various sources, such as software downloads, updates, patches, or installations. Testing all new software in a segregated environment involves verifying and validating the functionality and security of the software before deploying it to the production environment, using a separate system or network that is isolated and protected from the production environment. Testing all new software in a segregated environment can provide several benefits, such as:
Preventing the infection or propagation of malware to the production environment
Detecting and resolving any issues or risks caused by the software
Ensuring the compatibility and interoperability of the software with the production environment
Supporting and enabling the quality assurance and improvement of the software
The other options are not the best methods to prevent malware from being introduced into a production environment, but rather methods that can reduce or mitigate the risk of malware, but not eliminate it. Purchasing software from a limited list of retailers is a method that can reduce the risk of malware from being introduced into a production environment, but not prevent it. This method involves obtaining software only from trusted and reputable sources, such as official vendors or distributors, that can provide some assurance of the quality and security of the software. However, this method does not guarantee that the software is free of malware, as it may still contain hidden or embedded malware, or it may be tampered with or compromised during the delivery or installation process. Verifying the hash key or certificate key of all updates is a method that can reduce the risk of malware from being introduced into a production environment, but not prevent it. This method involves checking the authenticity and integrity of the software updates, patches, or installations, by comparing the hash key or certificate key of the software with the expected or published value, using cryptographic techniques and tools. However, this method does not guarantee that the software is free of malware, as it may still contain malware that is not detected or altered by the hash key or certificate key, or it may be subject to a man-in-the-middle attack or a replay attack that can intercept or modify the software or the key. Not permitting programs, patches, or updates from the Internet is a method that can reduce the risk of malware from being introduced into a production environment, but not prevent it. This method involves restricting or blocking the access or download of software from the Internet, which is a common and convenient source of malware, by applying and enforcing the appropriate security policies and controls, such as firewall rules, antivirus software, or web filters. However, this method does not guarantee that the software is free of malware, as it may still be obtained or infected from other sources, such as removable media, email attachments, or network shares.
A company whose Information Technology (IT) services are being delivered from a Tier 4 data center, is preparing a companywide Business Continuity Planning (BCP). Which of the following failures should the IT manager be concerned with?
Application
Storage
Power
Network
A company whose IT services are being delivered from a Tier 4 data center should be most concerned with application failures when preparing a companywide BCP. A BCP is a document that describes how an organization will continue its critical business functions in the event of a disruption or disaster. A BCP should include a risk assessment, a business impact analysis, a recovery strategy, and a testing and maintenance plan.
A Tier 4 data center is the highest level of data center classification, according to the Uptime Institute. A Tier 4 data center has the highest level of availability, reliability, and fault tolerance, as it has multiple and independent paths for power and cooling, and redundant and backup components for all systems. A Tier 4 data center has an uptime rating of 99.995%, which means it can only experience 0.4 hours of downtime per year. Therefore, the likelihood of a power, storage, or network failure in a Tier 4 data center is very low, and the impact of such a failure would be minimal, as the data center can quickly switch to alternative sources or routes.
However, a Tier 4 data center cannot prevent or mitigate application failures, which are caused by software bugs, configuration errors, or malicious attacks. Application failures can affect the functionality, performance, or security of the IT services, and cause data loss, corruption, or breach. Therefore, the IT manager should be most concerned with application failures when preparing a BCP, and ensure that the applications are properly designed, tested, updated, and monitored.
Which of the following types of technologies would be the MOST cost-effective method to provide a reactive control for protecting personnel in public areas?
Install mantraps at the building entrances
Enclose the personnel entry area with polycarbonate plastic
Supply a duress alarm for personnel exposed to the public
Hire a guard to protect the public area
Supplying a duress alarm for personnel exposed to the public is the most cost-effective method to provide a reactive control for protecting personnel in public areas. A duress alarm is a device that allows a person to signal for help in case of an emergency, such as an attack, a robbery, or a medical condition. A duress alarm can be activated by pressing a button, pulling a cord, or speaking a code word. A duress alarm can alert security personnel, law enforcement, or other responders to the location and nature of the emergency, and initiate appropriate actions. A duress alarm is a reactive control because it responds to an incident after it has occurred, rather than preventing it from happening.
The other options are not as cost-effective as supplying a duress alarm, as they involve more expensive or complex technologies or resources. Installing mantraps at the building entrances is a preventive control that restricts the access of unauthorized persons to the facility, but it also requires more space, maintenance, and supervision. Enclosing the personnel entry area with polycarbonate plastic is a preventive control that protects the personnel from physical attacks, but it also reduces the visibility and ventilation of the area. Hiring a guard to protect the public area is a deterrent control that discourages potential attackers, but it also involves paying wages, benefits, and training costs.
All of the following items should be included in a Business Impact Analysis (BIA) questionnaire EXCEPT questions that
determine the risk of a business interruption occurring
determine the technological dependence of the business processes
Identify the operational impacts of a business interruption
Identify the financial impacts of a business interruption
A Business Impact Analysis (BIA) is a process that identifies and evaluates the potential effects of natural and man-made disasters on business operations. The BIA questionnaire is a tool that collects information from business process owners and stakeholders about the criticality, dependencies, recovery objectives, and resources of their processes. The BIA questionnaire should include questions that:
Identify the operational impacts of a business interruption, such as loss of revenue, customer satisfaction, reputation, legal obligations, etc.
Identify the financial impacts of a business interruption, such as direct and indirect costs, fines, penalties, etc.
Determine the technological dependence of the business processes, such as hardware, software, network, data, etc.
Establish the recovery time objectives (RTO) and recovery point objectives (RPO) for each business process, which indicate the maximum acceptable downtime and data loss, respectively.
The BIA questionnaire should not include questions that determine the risk of a business interruption occurring, as this is part of the risk assessment process, which is a separate activity from the BIA. The risk assessment process identifies and analyzes the threats and vulnerabilities that could cause a business interruption, and estimates the likelihood and impact of such events. The risk assessment process also evaluates the existing controls and mitigation strategies, and recommends additional measures to reduce the risk to an acceptable level.
Intellectual property rights are PRIMARY concerned with which of the following?
Owner’s ability to realize financial gain
Owner’s ability to maintain copyright
Right of the owner to enjoy their creation
Right of the owner to control delivery method
Intellectual property rights are primarily concerned with the owner’s ability to realize financial gain from their creation. Intellectual property is a category of intangible assets that are the result of human creativity and innovation, such as inventions, designs, artworks, literature, music, software, etc. Intellectual property rights are the legal rights that grant the owner the exclusive control over the use, reproduction, distribution, and modification of their intellectual property. Intellectual property rights aim to protect the owner’s interests and incentives, and to reward them for their contribution to the society and economy.
The other options are not the primary concern of intellectual property rights, but rather the secondary or incidental benefits or aspects of them. The owner’s ability to maintain copyright is a means of enforcing intellectual property rights, but not the end goal of them. The right of the owner to enjoy their creation is a personal or moral right, but not a legal or economic one. The right of the owner to control the delivery method is a specific or technical aspect of intellectual property rights, but not a general or fundamental one.
An important principle of defense in depth is that achieving information security requires a balanced focus on which PRIMARY elements?
Development, testing, and deployment
Prevention, detection, and remediation
People, technology, and operations
Certification, accreditation, and monitoring
An important principle of defense in depth is that achieving information security requires a balanced focus on the primary elements of people, technology, and operations. People are the users, administrators, managers, and other stakeholders who are involved in the security process. They need to be aware, trained, motivated, and accountable for their security roles and responsibilities. Technology is the hardware, software, network, and other tools that are used to implement the security controls and measures. They need to be selected, configured, updated, and monitored according to the security standards and best practices. Operations are the policies, procedures, processes, and activities that are performed to achieve the security objectives and requirements. They need to be documented, reviewed, audited, and improved continuously to ensure their effectiveness and efficiency.
The other options are not the primary elements of defense in depth, but rather the phases, functions, or outcomes of the security process. Development, testing, and deployment are the phases of the security life cycle, which describes how security is integrated into the system development process. Prevention, detection, and remediation are the functions of the security management, which describes how security is maintained and improved over time. Certification, accreditation, and monitoring are the outcomes of the security evaluation, which describes how security is assessed and verified against the criteria and standards.
What is the MOST important consideration from a data security perspective when an organization plans to relocate?
Ensure the fire prevention and detection systems are sufficient to protect personnel
Review the architectural plans to determine how many emergency exits are present
Conduct a gap analysis of a new facilities against existing security requirements
Revise the Disaster Recovery and Business Continuity (DR/BC) plan
When an organization plans to relocate, the most important consideration from a data security perspective is to conduct a gap analysis of the new facilities against the existing security requirements. A gap analysis is a process that identifies and evaluates the differences between the current state and the desired state of a system or a process. In this case, the gap analysis would compare the security controls and measures implemented in the old and new locations, and identify any gaps or weaknesses that need to be addressed. The gap analysis would also help to determine the costs and resources needed to implement the necessary security improvements in the new facilities.
The other options are not as important as conducting a gap analysis, as they do not directly address the data security risks associated with relocation. Ensuring the fire prevention and detection systems are sufficient to protect personnel is a safety issue, not a data security issue. Reviewing the architectural plans to determine how many emergency exits are present is also a safety issue, not a data security issue. Revising the Disaster Recovery and Business Continuity (DR/BC) plan is a good practice, but it is not a preventive measure, rather a reactive one. A DR/BC plan is a document that outlines how an organization will recover from a disaster and resume its normal operations. A DR/BC plan should be updated regularly, not only when relocating.
Which of the following actions will reduce risk to a laptop before traveling to a high risk area?
Examine the device for physical tampering
Implement more stringent baseline configurations
Purge or re-image the hard disk drive
Change access codes
Purging or re-imaging the hard disk drive of a laptop before traveling to a high risk area will reduce the risk of data compromise or theft in case the laptop is lost, stolen, or seized by unauthorized parties. Purging or re-imaging the hard disk drive will erase all the data and applications on the laptop, leaving only the operating system and the essential software. This will minimize the exposure of sensitive or confidential information that could be accessed by malicious actors. Purging or re-imaging the hard disk drive should be done using secure methods that prevent data recovery, such as overwriting, degaussing, or physical destruction.
The other options will not reduce the risk to the laptop as effectively as purging or re-imaging the hard disk drive. Examining the device for physical tampering will only detect if the laptop has been compromised after the fact, but will not prevent it from happening. Implementing more stringent baseline configurations will improve the security settings and policies of the laptop, but will not protect the data if the laptop is bypassed or breached. Changing access codes will make it harder for unauthorized users to log in to the laptop, but will not prevent them from accessing the data if they use other methods, such as booting from a removable media or removing the hard disk drive.
When assessing an organization’s security policy according to standards established by the International Organization for Standardization (ISO) 27001 and 27002, when can management responsibilities be defined?
Only when assets are clearly defined
Only when standards are defined
Only when controls are put in place
Only procedures are defined
When assessing an organization’s security policy according to standards established by the ISO 27001 and 27002, management responsibilities can be defined only when standards are defined. Standards are the specific rules, guidelines, or procedures that support the implementation of the security policy. Standards define the minimum level of security that must be achieved by the organization, and provide the basis for measuring compliance and performance. Standards also assign roles and responsibilities to different levels of management and staff, and specify the reporting and escalation procedures.
Management responsibilities are the duties and obligations that managers have to ensure the effective and efficient execution of the security policy and standards. Management responsibilities include providing leadership, direction, support, and resources for the security program, establishing and communicating the security objectives and expectations, ensuring compliance with the legal and regulatory requirements, monitoring and reviewing the security performance and incidents, and initiating corrective and preventive actions when needed.
Management responsibilities cannot be defined without standards, as standards provide the framework and criteria for defining what managers need to do and how they need to do it. Management responsibilities also depend on the scope and complexity of the security policy and standards, which may vary depending on the size, nature, and context of the organization. Therefore, standards must be defined before management responsibilities can be defined.
The other options are not correct, as they are not prerequisites for defining management responsibilities. Assets are the resources that need to be protected by the security policy and standards, but they do not determine the management responsibilities. Controls are the measures that are implemented to reduce the security risks and achieve the security objectives, but they do not determine the management responsibilities. Procedures are the detailed instructions that describe how to perform the security tasks and activities, but they do not determine the management responsibilities.
