Unexpected outcomes may arise in production when using only sanitized data for the testing of applications. Sanitized data is data that has been purposely and permanently deleted or modified to prevent unauthorized access or misuse. Sanitized data may not reflect the real characteristics, patterns, or behaviors of the original data, and thus may not be suitable for testing applications that rely on data quality and accuracy. According to NIST, data sanitization methods can affect the usability of data for testing purposes1. The other options are not risks introduced by using sanitized data for testing applications, but rather risks that can be mitigated by using sanitized data. Data loss, data disclosure, and breaches of compliance obligations are possible consequences of using unsanitized data that contains sensitive or confidential information.

 The main reason for having senior management review and approve an information security strategic plan is to ensure that the plan aligns with the corporate governance of the organization. Corporate governance is the set of responsibilities and practices exercised by the board and executive management to provide strategic direction, ensure objectives are achieved, manage risks appropriately and verify that the organization’s resources are used responsibly1. An information security strategic plan is a document that defines the vision, mission, goals, objectives, scope and approach for the information security program of the organization2. The plan should be aligned with the organization’s business strategy, risk appetite, culture, values and objectives3. By reviewing and approving the plan, senior management demonstrates their commitment and support for the information security program, ensures its alignment with the corporate governance, and provides the necessary resources and authority for its implementation4. References = 1: CISM Review Manual 15th Edition, ISACA, 2017, page 172: CISM Review Manual 15th Edition, ISACA, 2017, page 253: CISM Review Manual 15th Edition, ISACA, 2017, page 264: CISM Review Manual 15th Edition, ISACA, 2017, page 27.

Senior management review and approval of an information security strategic plan is important to ensure that the plan is aligned with the organization's overall corporate governance objectives. It is also important to ensure that the plan takes into account any legal and regulatory requirements, as well as the resources and staff needed to properly implement the plan.

 An information security program is best positioned for success when it is closely aligned with the information security strategy, which defines the organization’s vision, mission, goals, objectives, and risk appetite for information security. The information security strategy provides the direction and guidance for developing and implementing the information security program, ensuring that it supports the organization’s business processes and objectives. The information security strategy also helps to establish the scope, boundaries, roles, responsibilities, and resources for the information security program.

= Security reporting is the process of providing relevant and timely information on the status and performance of the information security program to the stakeholders. Security reporting should be aligned with the business objectives and risk appetite of the organization, and should provide meaningful insights and recommendations for decision making and improvement. Security reporting should also include forward-looking trends, which are projections or predictions of future events or conditions based on historical data, current situation, and external factors. Forward-looking trends can help the organization anticipate and prepare for potential risks and opportunities, and adjust their strategies and plans accordingly.

One of the most effective ways to communicate forward-looking trends within security reporting is to use key risk indicators (KRIs). KRIs are metrics that measure the level of exposure or likelihood of a risk event occurring, and provide early warning signals of potential changes in the risk profile. KRIs can help the organization monitor and manage the key risks that may affect the achievement of their objectives, and take proactive actions to mitigate or avoid them. KRIs can also help the organization identify emerging risks and trends, and evaluate the effectiveness of their risk treatment options. KRIs should be aligned with the risk appetite and tolerance of the organization, and should be regularly reviewed and updated to reflect the changing risk environment.

The other options are not the most effective ways to communicate forward-looking trends within security reporting. Key control indicators (KCIs) are metrics that measure the effectiveness and efficiency of the security controls implemented to reduce the impact or likelihood of a risk event. KCIs can help the organization assess and improve the performance of their security processes and activities, and ensure compliance with the security policies and standards. However, KCIs do not directly measure the level of exposure or likelihood of a risk event, and may not provide sufficient information on the future trends and scenarios. Key performance indicators (KPIs) are metrics that measure the achievement of the security objectives and goals, and demonstrate the value and contribution of the information security program to the organization. KPIs can help the organization evaluate and communicate the results and outcomes of their security initiatives and projects, and align them with the business strategy and vision. However, KPIs do not directly measure the level of exposure or likelihood of a risk event, and may not provide sufficient information on the future trends and scenarios. Key goal indicators (KGIs) are metrics that measure the progress and completion of the security goals and targets, and indicate the degree of success and satisfaction of the information security program. KGIs can help the organization track and report the status and milestones of their security plans and actions, and ensure alignment with the stakeholder expectations and requirements. However, KGIs do not directly measure the level of exposure or likelihood of a risk event, and may not provide sufficient information on the future trends and scenarios. References = CISM Review Manual, 16th Edition, ISACA, 2020, pp. 77-78, 81-821; CISM Online Review Course, Domain 3: Information Security Program Development and Management, Module 4: Information Security Program Resources, ISACA2

= The method of operation used by the attacker is the most useful information for an information security manager when conducting a post-incident review of an attack. This information can help identify the root cause of the incident, the vulnerabilities exploited, the impact and severity of the attack, and the effectiveness of the existing security controls. The method of operation can also provide insights into the attacker’s motives, skills, and resources, which can help improve the organization’s threat intelligence and risk assessment. The cost of the attack to the organization, the location of the attacker, and the details from IDS logs are all relevant information for a post-incident review, but they are not as useful as the method of operation for improving the incident handling process and preventing future attacks. References = CISM Review Manual 2022, page 316; CISM Item Development Guide 2022, page 9; ISACA CISM: PRIMARY goal of a post-incident review should be to?

Measuring the percentage of controls integrated into business processes is the most accurate way to determine the alignment of an information security strategy with organizational goals, as this reflects the extent to which the information security program supports and enables the business objectives and activities, and reduces the friction and resistance from the business stakeholders. The percentage of controls integrated into business processes also indicates the maturity and effectiveness of the information security program, and the level of awareness and acceptance of the information security policies and standards among the business users. Number of blocked intrusion attempts, number of business cases reviewed by senior management, and trends in the number of identified threats to the business are not the most accurate ways to determine the alignment of an information security strategy with organizational goals, as they do not measure the impact and value of the information security program on the business performance and outcomes, and may not reflect the business priorities and expectations. References = CISM Review Manual 2023, page 291; CISM Review Questions, Answers & Explanations Manual 2023, page 372; ISACA CISM - iSecPrep, page 223; CISM Exam Overview - Vinsys4

= The organizational tolerance to service interruption is the most important consideration when defining a recovery strategy in a business continuity plan (BCP), as it reflects the degree of risk that the organization is willing to accept in the event of a disaster. The organizational tolerance to service interruption determines the acceptable level of downtime, data loss, or disruption that the organization can tolerate, and thus guides the selection of recovery objectives, strategies, and resources. Legal and regulatory requirements are external factors that influence the recovery strategy, but are not the primary consideration. Likelihood of a disaster is a factor that affects the recovery strategy, but is not the most important one. Geographical location of the backup site is a factor that affects the recovery strategy, but is not as critical as organizational tolerance to service interruption. References = CISM Review Manual, 16th Edition, page 1731; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 792

The most effective way to prevent information security incidents is to implement a security awareness training program for employees. Security awareness training provides employees with the knowledge and skills they need to identify potential security threats and protect their systems from unauthorized access and malicious activity. Security awareness training also helps to ensure that employees understand their roles and responsibilities when it comes to information security, and can help to reduce the risk of information security incidents by making employees more aware of potential risks. Additionally, implementing a security information and event management (SIEM) tool, deploying a consistent incident response approach, and deploying intrusion detection tools in the network environment can also help to reduce the risk of security incidents

 Introducing security requirements during the initiation phase would BEST ensure that security is integrated during application development because it would allow the security objectives and controls to be defined and aligned with the business needs and risk appetite before any design or coding is done. This would also facilitate the security by design approach, which is the most effective method to enhance the security of applications and application development activities1. Introducing security requirements early would also enable the collaboration between security professionals and developers, the identification and specification of security architectures, and the integration and testing of security controls throughout the development life cycle2. Employing global security standards during development processes (A) would help to ensure the consistency and quality of security practices, but it would not necessarily ensure that security is integrated during application development. Providing training on secure development practices to programmers (B) would help to raise the awareness and skills of developers, but it would not ensure that security is integrated during application development. Performing application security testing during acceptance testing © would help to verify the security of the application before deployment, but it would not ensure that security is integrated during application development. It would also be too late to identify and remediate any security issues that could have been prevented or mitigated earlier in the development process. References = 1: Five Key Components of an Application Security Program - ISACA1; 2: CISM Domain – Information Security Program Development | Infosec2

Network segmentation is the most effective control to prevent lateral movement. In ransomware attacks, attackers often breach one endpoint and move laterally across the network to reach critical assets.

Segmentation limits this movement by isolating systems into different zones or subnets, thereby reducing the attack surface and preventing unauthorized internal traversal.

DLP and encryption are primarily focused on data protection, not internal network movement.

IDS can detect intrusions but does not prevent movement like segmentation does.

“Network segmentation limits the scope of access for compromised systems and is a key strategy in preventing lateral movement in an attack.”

— CISM Review Manual 15th Edition, Chapter 3: Information Security Architecture, Section: Network Security*

Real-world example: “In the NotPetya and WannaCry incidents, poor internal segmentation allowed malware to propagate rapidly.”

Penetration testing simulates real-world attacks to identify any remaining exploitable vulnerabilities after controls are implemented. It validates that mitigation has been successful from an attacker’s perspective.

“Penetration testing is essential to verify the effectiveness of remediation efforts and ensure vulnerabilities can no longer be exploited.”

— CISM Review Manual 15th Edition, Chapter 2: Risk Management, Section: Security Testing and Evaluation*

Vulnerability assessments and audits are valuable, but pen testing provides practical assurance.

The primary responsibility of an information security manager in an organization that is implementing the use of company-owned mobile devices in its operations is to review and update existing security policies. Security policies are the foundation of an organi-zation’s security program, as they define the goals, objectives, principles, roles, respon-sibilities, and requirements for protecting information and systems. Security policies should be reviewed and updated regularly to reflect changes in the organization’s envi-ronment, needs, risks, and technologies1. Implementing the use of company-owned mobile devices in its operations is a significant change that may introduce new threats and vulnerabilities, as well as new opportunities and benefits, for the organiza-tion. Therefore, the information security manager should review and update existing security policies to address the following aspects2:

•The scope, purpose, and ownership of company-owned mobile devices

•The acceptable and unacceptable use of company-owned mobile devices

•The security standards and best practices for company-owned mobile devices

•The roles and responsibilities of users, managers, IT staff, and vendors regarding compa-ny-owned mobile devices

•The procedures for provisioning, managing, monitoring, and decommissioning company-owned mobile devices

•The incident response and reporting process for company-owned mobile devices

By reviewing and updating existing security policies, the information security manager can ensure that the organization’s security program is aligned with its business objec-tives and risk appetite, as well as compliant with applicable laws and regulations. The other options are not the primary responsibility of an information security manager in an organization that is implementing the use of company-owned mobile devices in its operations. They are possible actions or controls that may be derived from or support-ed by the updated security policies. Requiring remote wipe capabilities for devices is a technical control that can help prevent data loss or theft in case of device loss or com-promise3. Conducting security awareness training is an administrative control that can help educate users about the security risks and responsibilities associated with using company-owned mobile devices. Enforcing passwords and data encryption on the de-vices is a technical control that can help protect data confidentiality and integrity on company-owned mobile devices.

= The most important consideration when developing a multi-year plan for information security is to ensure alignment with the plans of other business units. Alignment means that the information security plan supports and enables the achievement of the business objectives, strategies, and priorities of the organization and its various units. Alignment also means that the information security plan is consistent and compatible with the plans of other business units, and that it addresses the needs, expectations, and requirements of the relevant stakeholders1 .

By ensuring alignment with the plans of other business units, the information security manager can achieve the following benefits1 :

Increase the value and effectiveness of information security: By aligning the information security plan with the business goals and drivers, the information security manager can demonstrate the value and contribution of information security to the organization’s performance, growth, and competitiveness. The information security manager can also ensure that the information security plan addresses the most critical and relevant risks and opportunities for the organization and its units, and that it provides adequate and appropriate protection and support for the organization’s assets, processes, and activities.

Enhance the communication and collaboration with other business units: By aligning the information security plan with the plans of other business units, the information security manager can enhance the communication and collaboration with the other business unit leaders and managers, who are the key stakeholders and partners in information security. The information security manager can also solicit and incorporate their input, feedback, and suggestions into the information security plan, and provide them with timely and relevant information, guidance, and support. The information security manager can also foster a culture of trust, respect, and cooperation among the different business units, and promote a shared vision and commitment to information security.

Optimize the use and allocation of resources for information security: By aligning the information security plan with the plans of other business units, the information security manager can optimize the use and allocation of resources for information security, such as budget, staff, time, or technology. The information security manager can also avoid duplication, conflict, or waste of resources among the different business units, and ensure that the information security plan is feasible, realistic, and sustainable. The information security manager can also leverage the resources and capabilities of other business units to enhance the information security plan, and provide them with the necessary resources and capabilities to implement and maintain the information security plan.

The other options are not the most important consideration when developing a multi-year plan for information security, as they are less strategic, comprehensive, or impactful than ensuring alignment with the plans of other business units. Ensuring contingency plans are in place for potential information security risks is an important component of the information security plan, but it is not the most important consideration, as it focuses on the reactive and preventive aspects of information security, rather than the proactive and enabling aspects. Allowing the information security program to expand its capabilities is an important objective of the information security plan, but it is not the most important consideration, as it depends on the availability and suitability of the resources, technologies, and opportunities for information security, and it may not align with the organization’s needs, priorities, or constraints. Demonstrating projected budget increases year after year is an important outcome of the information security plan, but it is not the most important consideration, as it reflects the cost and demand of information security, rather than the value and benefit of information security, and it may not be justified or supported by the organization’s financial situation or expectations1 . References = CISM Domain 1: Information Security Governance (ISG) [2022 update], CISM Domain 2: Information Risk Management (IRM) [2022 update], Aligning Information Security with Business Strategy - ISACA, [Aligning Information Security with Business Objectives - ISACA]

= Establishing metrics for each milestone is the best way to communicate the program’s effectiveness to stakeholders, as it provides a clear and measurable way to track the progress, performance, and outcomes of the information security governance framework. Metrics are quantifiable indicators that can be used to evaluate the achievement of specific objectives, goals, or standards. Metrics can also help to demonstrate the value, benefits, and return on investment of the information security program, as well as to identify and address the gaps, issues, or risks. Metrics for each milestone should be aligned with the organization’s strategy, vision, and mission, as well as with the expectations and needs of the stakeholders. Metrics for each milestone should also be SMART (specific, measurable, achievable, relevant, and time-bound), as well as consistent, reliable, and transparent.

The other options are not as important as establishing metrics for each milestone, as they do not provide a comprehensive and holistic way to communicate the program’s effectiveness to stakeholders. A control self-assessment (CSA) process is a technique to involve the staff in assessing the design, implementation, and effectiveness of the information security controls. It can help to increase the awareness, ownership, and accountability of the staff, as well as to identify and mitigate the risks. However, a CSA process alone is not enough to communicate the program’s effectiveness to stakeholders, as it does not measure the overall performance or maturity of the information security program. Automated reporting to stakeholders is a method to provide timely, accurate, and consistent information to the stakeholders about the status, results, and issues of the information security program. It can help to facilitate the communication, collaboration, and decision making among the stakeholders, as well as to ensure the compliance and transparency of the information security program. However, automated reporting alone is not enough to communicate the program’s effectiveness to stakeholders, as it does not evaluate the achievement or impact of the information security program. A monitoring process for the security policy is a process to ensure that the security policy is implemented, enforced, and reviewed in accordance with the organization’s objectives, standards, and regulations. It can help to maintain the relevance, adequacy, and effectiveness of the security policy, as well as to incorporate the feedback, changes, and improvements. However, a monitoring process alone is not enough to communicate the program’s effectiveness to stakeholders, as it does not cover the other aspects of the information security program, such as governance, risk management, incident management, or business continuity. References =

Evacuation drills provide real-time validation of physical security measures, staff preparedness, and response time during fire-related scenarios. They test both people and systems.

“Simulated exercises are the most effective method to evaluate real-world preparedness and the adequacy of response procedures.”

Paper reviews and awareness are useful, but only exercises reveal actual gaps in preparedness.

= Standardization of compliance requirements is the best approach to reduce unnecessary duplication of compliance activities, as it allows for a common understanding of the objectives and expectations of various stakeholders, such as regulators, auditors, customers, and business partners. Standardization also facilitates the alignment of compliance activities with the organization’s risk appetite and tolerance, and enables the identification and elimination of redundant or conflicting controls. References = CISM Review Manual, 27th Edition, page 721; CISM Review Questions, Answers & Explanations Database, 12th Edition, question 952
