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

= A multinational organization is required to follow governmental regulations with different security requirements at each of its operating locations. This means that the CISO has to deal with multiple and diverse legal, regulatory, and compliance issues across different jurisdictions and markets. The CISO should be most concerned with developing a security program that meets global and regional requirements, such as ISO/IEC 27001, NIST CSF, PCI DSS, GDPR, etc. These standards provide a framework for establishing, implementing, maintaining, and improving an information security management system (ISMS) that aligns with the organization’s business objectives and risk appetite. The CISO should also ensure that the security program is consistent and coherent across all operating locations, and that it complies with the specific regulations of each location. Therefore, option A is the most appropriate answer. References = CISM Review Manual 15th Edition, page 255; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, QID 234.In this scenario, the chief information security officer (CISO) should be most concerned with developing a security program that meets the global and regional requirements of the organization. This includes considering the different legal and regulatory requirements of each operating location, and designing a security program that meets all of these requirements. The CISO should also ensure effective communication with local regulatory bodies to ensure compliance and understanding of the security program. Additionally, the CISO should use industry best practices and defined security policies and standards to ensure the program meets all applicable requirements.

Results from a gap analysis would provide the most useful information for planning purposes when preparing an action plan to achieve compliance with local regulatory requirements by an established deadline. A gap analysis is an assessment of the difference between an organization’s current state of compliance and its desired level or standard. It is a process used to identify potential areas for improvement by comparing actual performance with expected performance. A gap analysis can help to prioritize the actions needed to close the gaps and comply with the regulatory requirements, as well as to estimate the resources and time required for each action1. The other options are not as useful as results from a gap analysis for planning purposes when preparing an action plan to achieve compliance with local regulatory requirements by an established deadline. Deadlines and penalties for noncompliance are important factors to consider, but they do not provide information on how to achieve compliance or what actions are needed2. Results from a business impact analysis (BIA) are useful for identifying the critical processes and assets that need to be protected, but they do not provide information on how to comply with the regulatory requirements or what actions are needed3. An inventory of security controls currently in place is useful for assessing the current state of compliance, but it does not provide information on how to comply with the regulatory requirements or what actions are needed4.

 An information security post-incident review is a process that aims to identify the root causes, impacts, lessons learned, and improvement actions of a security incident. The highest priority during a post-incident review should be evaluating the effectiveness of the incident response, which means assessing how well the incident response plan, procedures, roles, resources, and communication were executed and aligned with the business objectives and requirements. Evaluating the incident response effectiveness can help to identify the gaps, weaknesses, strengths, and opportunities for improvement in the incident response process and capabilities. Documenting actions taken in sufficient detail, updating key risk indicators (KRIs), and evaluating the performance of incident response team members are also important activities during a post-incident review, but they are not as critical as evaluating the incident response effectiveness, which can provide a holistic and strategic view of the incident response maturity and value.

During post-incident reviews, the highest priority should be given to evaluating the effectiveness of the incident response effort. This includes assessing the accuracy of the response to the incident, the timeliness of the response, and the efficiency of the response. It is important to assess the effectiveness of the response in order to identify areas for improvement and ensure that future responses can be more effective. Documenting the actions taken in sufficient detail, updating key risk indicators (KRIs), and evaluating the performance of incident response team members are all important components of a post-incident review, but evaluating incident response effectiveness should be given the highest priority.

The explanation given in the manual is:

The information security manager’s knowledge of the business is the most critical factor for information security program success because it enables him or her to align security objectives with business goals and communicate effectively with senior management and other stakeholders. The other choices are important elements of an information security program but not as critical as the information security manager’s knowledge of the business.

An information security program is a set of policies, procedures, standards, guidelines, and tools that aim to protect an organization’s information assets from threats and ensure compliance with laws and regulations. An information security manager is a professional who oversees and coordinates the implementation and maintenance of an information security program. An information security manager should have a good understanding of the business environment, culture, strategy, processes, and needs of an organization to ensure that security supports its objectives.

Process owners are the people who are responsible for the design, execution, and improvement of the business processes that support the organization’s objectives and operations. Process owners have the greatest importance in the development of an information security strategy, as they provide the input and feedback on the business requirements, expectations, and priorities that the information security strategy should address and support. Process owners also help to identify and assess the risks and impacts that the business processes face, and to define and implement the security controls and measures that can mitigate or reduce them. Process owners also facilitate the alignment and integration of the information security strategy with the business strategy, as well as the communication and collaboration among the various stakeholders and functions involved in the information security program. End users, security architects, and corporate auditors are all important stakeholders in the information security program, but they do not have the greatest importance in the development of an information security strategy. End users are the people who use the information systems and services that the information security program protects and enables. End users provide the input and feedback on the usability, functionality, and performance of the information systems and services, as well as the security awareness and behavior that they exhibit. Security architects are the people who design and implement the security architecture that supports the information security strategy. Security architects provide the input and feedback on the technical requirements, capabilities, and solutions that the information security strategy should leverage and optimize. Corporate auditors are the people who evaluate and verify the compliance and effectiveness of the information security program. Corporate auditors provide the input and feedback on the standards, regulations, and best practices that the information security strategy should follow and adhere to. Therefore, process owners have the greatest importance in the development of an information security strategy, as they provide the input and feedback on the business requirements, expectations, and priorities that the information security strategy should address and support. References = CISM Review Manual 2023, page 31 1; CISM Practice Quiz 2

 The CEO is the best able to influence the security culture within an organization because the CEO sets the tone and direction for the organization and has the authority and responsibility to ensure that the organization’s objectives are aligned with its strategy. The CEO can also communicate the importance and value of information security to all stakeholders and foster a culture of security awareness and accountability. The CISO, CIO and COO are important roles in information security management, but they do not have the same level of influence and authority as the CEO. References = CISM Review Manual, 16th Edition, page 221; CISM Exam Content Outline, Domain 1, Task 12

The Chief Information Security Officer (CISO) is responsible for leading and coordinating an organization's information security program, and as such, is in a prime position to influence the security culture within the organization. The CISO is responsible for setting policies and standards, educating employees about security risks and best practices, and ensuring that the organization is taking appropriate measures to mitigate security risks. By demonstrating a strong commitment to information security, the CISO can help to create a security-aware culture within the organization.

 The organization’s vision and mission should be the PRIMARY basis for an information security strategy, as they define the purpose and direction of the organization and its information security needs. A comprehensive gap analysis is a tool to identify the current state and desired state of information security, and the actions needed to close the gap. Information security policies are the high-level statements of management’s intent and expectations for information security, and are derived from the information security strategy. Audit and regulatory requirements are external factors that influence the information security strategy, but are not the primary basis for it. References = CISM Review Manual, 16th Edition, pages 17-181; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 782

The primary basis for an information security strategy should be the organization's vision and mission. The organization's vision and mission should be the foundation for the security strategy, and should inform and guide the security policies, procedures, and practices that are implemented. The results of a comprehensive gap analysis, information security policies, and audit and regulatory requirements should all be taken into consideration when developing the security strategy, but should not be the primary basis.

A ransomware incident is a type of cyberattack that encrypts the victim’s data and demands a ransom for its decryption. Ransomware can cause significant disruption and damage to critical systems and data, as well as financial losses and reputational harm. To recover from a ransomware incident, the organization needs to have reliable and accessible backups of its data, preferably in an encrypted format. However, if the backups are unavailable or corrupt, the organization will face a major challenge in restoring its data and operations. Therefore, option D is the most challenging factor for the recovery of critical systems and data following a ransomware incident. References = CISA MS-ISAC Ransomware Guide1, page 9; How to Write an Incident Response Plan for Ransomware Recovery2.

Embedding compliance requirements within operational processes ensures that they are consistently followed and monitored as part of normal business activities. This provides ongoing assurance that legal and regulatory compliance requirements can be met. The other choices are not as effective as embedding compliance requirements within operational processes.

Regulatory compliance involves following external legal mandates set forth by state, federal, or international government2. Compliance requirements may vary depending on the industry, location, and nature of the organization2. Compliance helps organizations avoid legal penalties, protect their reputation, and ensure ethical conduct2.

The primary benefit of establishing a clear definition of a security incident is that it helps to develop effective escalation and response procedures. A security incident is an event or an attempt that disrupts or threatens the normal operations, security, or privacy of an organization’s information or systems1. A clear definition of a security in-cident helps to:

•Distinguish between normal and abnormal events, and between security-relevant and non-security-relevant events

•Determine the severity and impact of an incident, and the appropriate level of response

•Assign roles and responsibilities for incident detection, reporting, analysis, containment, eradication, recovery, and post-incident activities

•Establish criteria and thresholds for escalating incidents to higher authorities or external parties

•Define the communication channels and protocols for incident notification and coordina-tion

•Document the incident response process and procedures in a formal plan

According to NIST, a clear definition of a security incident is one of the key compo-nents of an effective incident response capability2. The other options are not the prima-ry benefits of establishing a clear definition of a security incident. Communicating the incident response process to stakeholders is important, but it is not the main purpose of defining a security incident. Adequately staffing and training incident response teams is essential, but it depends on other factors besides defining a security inci-dent. Making tabletop testing more effective is a possible outcome, but not a direct benefit of defining a security incident.

 When an organization is aligning its incident response capability with a public cloud service provider, the information security manager’s first course of action should be to review the provider’s incident definitions and notification criteria. This is because the provider’s incident definitions and notification criteria may differ from the organization’s own, and may affect the scope, severity, and urgency of the incidents that need to be reported and handled. By reviewing the provider’s incident definitions and notification criteria, the information security manager can ensure that there is a common understanding and agreement on what constitutes an incident, how it is classified, and when and how it is communicated. This will help to avoid confusion, delays, or conflicts in the incident response process, and to establish clear roles and responsibilities between the organization and the provider. References = CISM Review Manual, 16th Edition, page 1021

Reviewing the provider’s incident definitions and notification criteria is the FIRST course of action when aligning the organization’s incident response capability with a public cloud service provider. This is because the organization needs to understand how the provider defines and classifies incidents, what their roles and responsibilities are, and how they will communicate with the organization in case of an incident. This will help the organization align its own incident response processes and expectations with the provider’s and ensure a coordinated and effective response.

Information owners are responsible for determining the initial recovery time objective (RTO) for their information assets and processes, as they are the ones who understand the business requirements and impact of a disruption. An external consultant may assist in conducting the business impact analysis (BIA), but does not have the authority to decide the RTO. An information security manager may provide input on the security aspects of the RTO, but does not have the business perspective to determine the RTO. A business continuity coordinator may facilitate the BIA process and ensure the alignment of the RTO with the business continuity plan, but does not have the ownership of the information assets and processes. References = CISM Review Manual 15th Edition, page 202.

When performing a business impact analysis (BIA), it is the responsibility of the business continuity coordinator to determine the initial recovery time objective (RTO). The RTO is a critical component of the BIA and should be determined in cooperation with the information owners. The RTO should reflect the maximum tolerable period of disruption (MTPD) and should be used to guide the development of the recovery strategy.

 The best way to ensure appropriate security controls are built into software is to integrate security throughout the development process. This means that security should be considered from the initial stages of planning, design, coding, testing, deployment, and maintenance of the software. Integrating security throughout the development process helps to identify and mitigate security risks early, reduce the cost and complexity of fixing vulnerabilities later, improve the quality and reliability of the software, and enhance the trust and confidence of the users and customers. Integrating security throughout the development process also aligns with the best practices and standards of information security governance, such as the CISM framework123.

CISSP domain 8 overview: Software development security4

 A security operations center (SOC) relies on the centralized logging server to collect, store, analyze and correlate security events from various sources such as firewalls, intrusion detection systems, antivirus software, etc. The centralized logging server uses the timestamps of the events to perform the analysis and correlation. If the IT system clocks are not synchronized with the centralized logging server, the SOC will face difficulties in identifying the sequence and causality of the events, which will affect its ability to detect and respond to potential security breaches. Therefore, this presents the greatest challenge to the SOC’s awareness of potential security breaches.

Operating systems that are no longer supported by the vendor may pose a security risk, but they can be mitigated by applying compensating controls such as isolation, segmentation, monitoring, etc. The patch management system that does not deploy patches in a timely manner may also increase the vulnerability exposure, but it can be remediated by prioritizing and applying the critical patches as soon as possible. An organization that has a decentralized data center that uses cloud services may face some challenges in ensuring the security and compliance of the cloud environment, but it can leverage the cloud service provider’s security capabilities and tools to enhance the SOC’s visibility and control. Therefore, these options are not the greatest challenges to the SOC’s awareness of potential security breaches. References = CISM Certified Information Security Manager Study Guide, Chapter 8: Security Operations and Incident Management, page 2691; CISM Foundations: Module 4 Course, Part One: Security Operations and Incident Management2; RSI Security, Common Challenges of SOC Teams3; Infosec Matter, Security Operations Center: Challenges of SOC Teams4
