Top Tips for Passing the Isaca CISM Exam on Your First Try

The incident response team can best leverage the results of a business impact analysis (BIA) by assigning restoration priority during incidents. A BIA is a process that identifies and evaluates the criticality and dependency of the organization’s business functions, processes, and resources, and the potential impacts and consequences of their disruption or loss. The BIA results provide the basis for determining the recovery objectives, strategies, and plans for the organization’s business continuity and disaster recovery. By using the BIA results, the incident response team can prioritize the restoration of the most critical and time-sensitive business functions, processes, and resources, and allocate the appropriate resources, personnel, and time to minimize the impact and duration of the incident.

Determining total cost of ownership (TCO) (B) is not a relevant way to leverage the results of a BIA, as it is not directly related to incident response. TCO is a financial metric that estimates the total direct and indirect costs of owning and operating an asset or a system over its lifecycle. TCO may be useful for evaluating the cost-effectiveness and return on investment of different security solutions or alternatives, but it does not help the incident response team to respond to or recover from an incident.

Evaluating vendors critical to business recovery © is also not a relevant way to leverage the results of a BIA, as it is not a primary responsibility of the incident response team. Evaluating vendors critical to business recovery is a part of the vendor management process, which involves selecting, contracting, monitoring, and reviewing the vendors that provide essential products or services to support the organization’s business continuity and disaster recovery. Evaluating vendors critical to business recovery may be done before or after an incident, but not during an incident, as it does not contribute to the incident response or restoration activities.

Calculating residual risk after the incident recovery phase (D) is also not a relevant way to leverage the results of a BIA, as it is not a timely or effective use of the BIA results. Residual risk is the risk that remains after the implementation of risk treatment or mitigation measures. Calculating residual risk after the incident recovery phase may be done as a part of the incident review or improvement process, but not during the incident response or restoration phase, as it does not help the incident response team to resolve or contain the incident.

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 CISO should first determine the extent of the impact to the organization by assessing the nature and scope of the data breach, the type and sensitivity of the data involved, the potential harm to the organization and its customers, and the legal and contractual obligations of the organization and the service provider. This will help the CISO to prioritize the appropriate actions and resources to respond to the incident and mitigate the risks. The other options are possible actions that the CISO may take after determining the impact, depending on the circumstances and the outcomes of the investigation. References = CISM Review Manual 15th Edition, page 2231; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, Question ID: 1030

 The online bank should first isolate the affected network segment, as this is the most effective way to contain the attack and prevent it from spreading to other parts of the network or compromising more data or systems. Isolating the affected network segment also helps to preserve the evidence and facilitate the investigation and recovery process. Reporting the root cause to the board of directors, assessing whether personally identifiable information (Pll) is compromised, and shutting down the entire network are not the first actions that the online bank should take, as they may not be feasible or appropriate at the time of the attack, and may cause more disruption, confusion, or damage to the business operations and reputation. References = CISM Review Manual 2023, page 1641; CISM Review Questions, Answers & Explanations Manual 2023, page 362; ISACA CISM - iSecPrep, page 213

 The most important thing to include in the outsourcing agreement for disaster recovery activities is the recovery time objectives (RTOs). RTOs are the maximum acceptable time frames within which the critical business processes and information systems must be restored after a disaster or disruption. RTOs are based on the business impact analysis (BIA) and the risk assessment, and they reflect the business continuity requirements and expectations of the organization. By including the RTOs in the outsourcing agreement, the organization can ensure that the service provider is aware of and committed to meeting the agreed service levels and minimizing the downtime and losses in the event of a disaster. The other options are not as important as the RTOs, although they may be relevant and useful to include in the outsourcing agreement depending on the scope and nature of the disaster recovery services. References = CISM Review Manual 15th Edition, page 2471; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, Question ID: 1033

 Network isolation techniques are immediately implemented after a security breach to reduce the extent of further damage by limiting the access and communication of the compromised systems or networks with the rest of the environment. This can help prevent the spread of malware, the exfiltration of data, or the escalation of privileges by the attackers. Network isolation techniques can include disconnecting the affected systems or networks from the internet, blocking or filtering certain ports or protocols, or creating separate VLANs or subnets for the isolated systems or networks. Network isolation techniques are part of the incident response process and should be performed as soon as possible after detecting a security breach. References = CISM Review Manual 15th Edition, page 308-3091; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, Question ID: 1162

A parallel test is the best method to evaluate the effectiveness of an alternate processing site when continuous uptime is required. A parallel test involves processing the same transactions or data at both the primary and the alternate site simultaneously, and comparing the results for accuracy and consistency. A parallel test can validate the functionality, performance, and reliability of the alternate site without disrupting the normal operations at the primary site. A parallel test can also identify and resolve any issues or discrepancies between the two sites before a real disaster occurs. A parallel test can provide a high level of assurance and confidence that the alternate site can support the organization’s continuity requirements.

References = CISM Review Manual, 16th Edition, Chapter 3: Information Security Program Development and Management, Section: Business Continuity Plan (BCP) Testing, page 1861; CISM Review Questions, Answers & Explanations Manual, 10th Edition, Question 56, page 522.

A parallel test is the best method to evaluate the effectiveness of an alternate processing site when continuous uptime is required because it involves processing data at both the primary and alternate sites simultaneously without disrupting the normal operations1. A full interruption test would cause downtime and potential loss of data or revenue2. A simulation test would not provide a realistic assessment of the alternate site’s capabilities3. A tabletop test would only involve a discussion of the procedures and scenarios without actually testing the site4.

 The best indicator that information assets are classified accurately is appropriate prioritization of information risk treatment. Information asset classification is the process of assigning a level of sensitivity or criticality to information assets based on their value, impact, and legal or regulatory requirements. The purpose of information asset classification is to facilitate the identification and protection of information assets according to their importance and risk exposure. Therefore, if information assets are classified accurately, the organization can prioritize the information risk treatment activities and allocate the resources accordingly. The other options are not direct indicators of information asset classification accuracy, although they may be influenced by it. References = CISM Review Manual 15th Edition, page 671; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, Question ID: 1031

 Before implementing any changes to the security incident response plan, the information security manager should first conduct a gap analysis to identify the current state of the plan and compare it with the new requirements. A gap analysis is a systematic process of evaluating the differences between the current and desired state of a system, process, or program. A gap analysis can help to identify the strengths and weaknesses of the existing plan, the gaps that need to be addressed, the priorities and dependencies of the actions, and the resources and costs involved. A gap analysis can also help to create a business case for the changes and justify the investment. A gap analysis can be conducted using various methods and tools, such as frameworks, standards, benchmarks, questionnaires, interviews, audits, or tests1234.

PROACTIVE DETECTION - GOOD PRACTICES GAP ANALYSIS RECOMMENDATIONS4

The most important consideration when establishing information security policies for an organization is to ensure that senior management supports the policies. Senior management support is essential for the successful implementation and enforcement of information security policies, as it demonstrates the commitment and accountability of the organization’s leadership to information security. Senior management support also helps to allocate adequate resources, establish clear roles and responsibilities, and promote a security-aware culture within the organization. Without senior management support, information security policies may not be aligned with the organization’s goals and objectives, may not be communicated and disseminated effectively, and may not be followed or enforced consistently.

Job descriptions that include requirements to read security policies are a way of ensuring that employees are aware of their security obligations, but they are not the most important consideration when establishing information security policies. The policies should be relevant and applicable to the employees’ roles and functions, and should be reinforced by regular training and awareness programs.

The policies should be updated periodically to reflect the changes in the organization’s environment, risks, and requirements, but updating them annually may not be sufficient or necessary. The frequency of updating the policies should depend on the nature and impact of the changes, and should be determined by a defined policy review process.

The policies should be aligned with industry best practices, standards, and frameworks, but this is not the most important consideration when establishing information security policies. The policies should also be customized and tailored to the organization’s specific context, needs, and expectations, and should be consistent with the organization’s vision, mission, and values. References =

 A capability maturity model (CMM) is a framework that helps organizations assess and improve their processes and capabilities in various domains, such as software development, project management, information security, and others1. A CMM defines a set of levels or stages that represent the degree of maturity or effectiveness of an organization’s processes and capabilities in a specific domain. Each level has a set of criteria or characteristics that an organization must meet to achieve that level of maturity. A CMM also provides guidance and best practices on how to progress from one level to another, and how to measure and monitor the performance and improvement of the processes and capabilities2.

A CMM is most helpful in determining an organization’s current capacity to mitigate risks, because it provides a systematic and objective way to evaluate the strengths and weaknesses of the organization’s processes and capabilities related to risk management. A CMM can help an organization identify the gaps and opportunities for improvement in its risk management practices, and prioritize the actions and resources needed to address them. A CMM can also help an organization benchmark its risk management maturity against industry standards or best practices, and demonstrate its compliance with regulatory or contractual requirements3.

The other options are not as helpful as a CMM in determining an organization’s current capacity to mitigate risks, because they are either more specific, limited, or dependent on a CMM. A vulnerability assessment is a process of identifying and analyzing the vulnerabilities in an organization’s systems, networks, or applications, and their potential impact on the organization’s assets, operations, or reputation. A vulnerability assessment can help an organization identify the sources and levels of risk, but it does not provide a comprehensive or holistic view of the organization’s risk management maturity or effectiveness4. IT security risk and exposure is a measure of the likelihood and impact of a security breach or incident on an organization’s IT assets, operations, or reputation. IT security risk and exposure can help an organization quantify and communicate the level of risk, but it does not provide a framework or guidance on how to improve the organization’s risk management processes or capabilities5. A business impact analysis (BIA) is a process of identifying and evaluating the potential effects of a disruption or disaster on an organization’s critical business functions, processes, or resources. A BIA can help an organization determine the priorities and requirements for business continuity and disaster recovery, but it does not provide a method or standard for assessing or enhancing the organization’s risk management maturity or effectiveness. References = 1: CMMI Institute - What is CMMI? - Capability Maturity Model Integration 2: Capability Maturity Model and Risk Register Integration: The Right … 3: Performing Risk Assessments of Emerging Technologies - ISACA 4: CISM Review Manual 15th Edition, Chapter 4, Section 4.2 5: CISM Review Manual 15th Edition, Chapter 4, Section 4.3 : CISM Review Manual 15th Edition, Chapter 4, Section 4.4

 Unannounced testing is the most accurate way to assess the effectiveness of controls, as it simulates a real-world scenario and does not allow the staff to prepare or modify their behavior in advance. Mature change management processes, senior management support, and well-defined security policies are all important factors for establishing and maintaining a strong security posture, but they do not directly measure the performance of controls. References = CISM Review Manual, 16th Edition, page 149. CISM Questions, Answers & Explanations Database, question ID 1003.

 Strengthening endpoint security is the most immediate focus when shifting to a work-from-home model with an increased need for remote access security, as this reduces the risk of unauthorized access, data leakage, malware infection, and other threats that may compromise the confidentiality, integrity, and availability of the organization’s information assets. Moving to a zero trust access model, enabling network-level authentication, and enhancing cyber response capability are also important, but not as urgent as strengthening endpoint security, as they require more time, resources, and planning to implement effectively. References = CISM Review Manual 2023, page 1561; CISM Review Questions, Answers & Explanations Manual 2023, page 302; ISACA CISM - iSecPrep, page 153

= The most useful source of information for a newly hired information security manager who has been tasked with developing and implementing an information security strategy is the organization’s mission statement and roadmap. The mission statement defines the organization’s purpose, vision, values, and goals, and the roadmap outlines the organization’s strategic direction, priorities, and initiatives. By reviewing the mission statement and roadmap, the information security manager can understand the organization’s business objectives, risk appetite, and security needs, and align the information security strategy with them. The information security strategy should support and enable the organization’s mission and roadmap, and provide the security governance, policies, standards, and controls to protect the organization’s information assets and processes.

The capabilities and expertise of the information security team (A) are important factors for the information security manager to consider, but they are not the most useful source of information for developing and implementing an information security strategy. The information security team is responsible for executing and maintaining the information security program and activities, such as risk management, security awareness, incident response, and compliance. The information security manager should assess the capabilities and expertise of the information security team to identify the strengths, weaknesses, opportunities, and threats, and to plan the resource allocation, training, and development of the team. However, the capabilities and expertise of the information security team do not directly inform the information security strategy, which should be driven by the organization’s business objectives, risk appetite, and security needs.

A prior successful information security strategy © is a possible source of information for the information security manager to refer to, but it is not the most useful one. A prior successful information security strategy is a strategy that has been implemented and evaluated by another organization or a previous information security manager, and has achieved the desired security outcomes and benefits. The information security manager can learn from the best practices, lessons learned, and challenges of a prior successful information security strategy, and apply them to the current organization or situation. However, a prior successful information security strategy may not be relevant, applicable, or suitable for the organization, as it may not reflect the current or future business objectives, risk appetite, and security needs of the organization, or the changing threat landscape and business environment.

The organization’s information technology (IT) strategy (D) is also a possible source of information for the information security manager to consult, but it is not the most useful one. The IT strategy is a strategy that defines the IT vision, goals, and initiatives of the organization, and how IT supports and enables the business processes and activities. The information security manager should review the IT strategy to understand the IT infrastructure, systems, and services of the organization, and how they relate to the information security program and activities. However, the IT strategy is not the primary driver of the information security strategy, which should be aligned with the organization’s business objectives, risk appetite, and security needs, and not only with the IT objectives, capabilities, and requirements.

Security hardening is the process of applying security configuration settings to systems and software to reduce their attack surface and improve their resistance to threats1. Security hardening settings are based on industry standards and best practices, such as the CIS Benchmarks2, which provide recommended security configurations for various software applications, operating systems, and network devices. However, security hardening settings may not always be compatible with the business requirements and objectives of an organization, and may negatively impact the functionality, performance, or usability of the systems and software3. Therefore, before applying any security hardening settings, an information security manager should perform a risk assessment to evaluate the potential benefits and drawbacks of the settings, and to identify and prioritize the risks associated with them. A risk assessment is a systematic process of identifying, analyzing, and evaluating the risks that an organization faces, and determining the appropriate risk responses. A risk assessment helps the information security manager to balance the security and business needs of the organization, and to communicate the risk level and impact to the relevant stakeholders. A risk assessment should be performed first, before taking any other actions, such as reducing security hardening settings, informing business management of the risk, or documenting a security exception, because it provides the necessary information and justification for making informed and rational decisions. References = 1: Basics of the CIS Hardening Guidelines | RSI Security 2: CIS Baseline Hardening and Security Configuration Guide | CalCom 3: CISM Review Manual 15th Edition, page 121 : CISM Review Manual 15th Edition, page 122 : CISM Review Manual 15th Edition, page 145 : CISM Review Manual 15th Edition, page 146 : CISM Review Manual 15th Edition, page 147
