Infrastructure as a Service (IaaS) is a cloud model in which the cloud service provider (CSP) offers the basic computing resources, such as servers, storage, network, and virtualization, as a service over the internet. The cloud service buyer (CSB) is responsible for installing, configuring, managing, and securing the operating systems, applications, data, and middleware on top of the infrastructure. Therefore, the CSB assumes the most security responsibility in the IaaS model, as it has to protect the confidentiality, integrity, and availability of its own assets and information in the cloud environment.

In contrast, in the other cloud models, the CSP takes over more security responsibility from the CSB, as it provides more layers of the service stack. In Disaster Recovery as a Service (DRaaS), the CSP offers the replication and recovery of the CSB’s data and applications in the event of a disaster. In Platform as a Service (PaaS), the CSP offers the development and deployment tools, such as programming languages, frameworks, libraries, and databases, as a service. In Software as a Service (SaaS), the CSP offers the complete software applications, such as email, CRM, or ERP, as a service. In these models, the CSB has less control and visibility over the underlying infrastructure, platform, or software, and has to rely on the CSP’s security measures and contractual agreements.

 The primary reason to perform regular reviews of the cybersecurity threat landscape is to compare emerging trends with the existing organizational security posture, as this helps the information security manager to identify and prioritize the gaps and risks that need to be addressed. The cybersecurity threat landscape is dynamic and constantly evolving, and the organization’s security posture may not be adequate or aligned with the current and future threats. By reviewing the threat landscape regularly, the information security manager can assess the effectiveness and maturity of the security program, and recommend appropriate actions and controls to improve the security posture and reduce the likelihood and impact of cyberattacks. References = CISM Review Manual 2023, page 831; CISM Review Questions, Answers & Explanations Manual 2023, page 322; ISACA CISM - iSecPrep, page 173

= The most important consideration when establishing an organization’s information security governance committee is to ensure that members represent functions across the organization. This is because the information security governance committee is responsible for setting the direction, scope, and objectives of the information security program, and for ensuring that the program aligns with the organization’s business goals and strategies. By having members from different functions, such as finance, human resources, operations, legal, and IT, the committee can ensure that the information security program considers the needs, expectations, and perspectives of various stakeholders, and that the program supports the organization’s mission, vision, and values. Having a diverse and representative committee also helps to foster a culture of security awareness and accountability throughout the organization, and to promote collaboration and communication among different functions.

Members having knowledge of information security controls, members being business risk owners, and members being rotated periodically are all desirable characteristics of an information security governance committee, but they are not the most important consideration. Members having knowledge of information security controls can help the committee to understand the technical aspects of information security and to evaluate the effectiveness and efficiency of the information security program. However, having technical knowledge is not sufficient to ensure that the information security program is aligned with the organization’s business goals and strategies, and that the program considers the needs and expectations of various stakeholders. Members being business risk owners can help the committee to identify and prioritize the information security risks that affect the organization’s business objectives, and to allocate appropriate resources and responsibilities for managing those risks. However, being a business risk owner does not necessarily imply that the member has a comprehensive and balanced view of the organization’s information security needs and expectations, and that the member can represent the interests and perspectives of various functions. Members being rotated periodically can help the committee to maintain its independence and objectivity, and to avoid conflicts of interest or complacency. However, rotating members too frequently can also reduce the continuity and consistency of the information security program, and can affect the committee’s ability to monitor and evaluate the performance and progress of the information security program. References =

 A successful information security program is one that aligns with the business objectives and strategy, supports the business processes and functions, and protects the information assets from threats and vulnerabilities. The most important factor of such a program is that it is focused on risk management, which means that it identifies, assesses, treats, and monitors the information security risks that could affect the business continuity, reputation, and value. Risk management helps to prioritize the security activities and resources, allocate the appropriate budget and resources, implement the necessary controls and measures, and evaluate the effectiveness and efficiency of the program. Risk management also enables the program to adapt to the changing business and threat environment, and to continuously improve the security posture and performance. A program that follows industry best practices, is based on a well-developed strategy, and is cost-efficient and within budget are all desirable attributes, but they are not sufficient to ensure the success of the program without a risk management focus. References = CISM Review Manual 15th Edition, page 411; CISM Practice Quiz, question 1242

 = Penetration testing is most appropriate when a new system is about to go live, because it is a method of evaluating the security of a system by simulating an attack from a malicious source. Penetration testing can help to identify and exploit vulnerabilities, assess the impact and risk of a breach, and provide recommendations for remediation and improvement. Penetration testing can also help to validate the effectiveness of the security controls and policies implemented for the new system, and ensure compliance with relevant standards and regulations. Penetration testing is usually performed after the system has undergone other types of testing, such as functional, performance, and usability testing, and before the system is deployed to the production environment. Penetration testing is not as appropriate when a new system is being designed, because the system is still in the early stages of development and may not have all the features and functionalities implemented. Penetration testing at this stage may not provide a realistic or comprehensive assessment of the system’s security, and may cause delays or disruptions in the development process. Penetration testing is also not as appropriate when a security policy is being developed, because the policy is a high-level document that defines the goals, objectives, and principles of information security for the organization. Penetration testing is a technical and operational activity that tests the implementation and enforcement of the policy, not the policy itself. Penetration testing is also not as appropriate when a security incident has occurred, because the incident may have already compromised the system and caused damage or loss. Penetration testing at this stage may not be able to prevent or mitigate the incident, and may interfere with the incident response and recovery efforts. Penetration testing after an incident may be useful for forensic analysis and lessons learned, but it is not the primary or immediate response to an incident. References = CISM Review Manual, 16th Edition, ISACA, 2021, pages 229-230, 233-234.

Information security governance is the process of establishing and maintaining a framework to provide assurance that information security strategies are aligned with business objectives and consistent with applicable laws and regulations. In addition to executive sponsorship and business alignment, a critical factor for effective information security governance is ownership of security, which means that the roles and responsibilities for information security are clearly defined and assigned to the appropriate stakeholders, such as business owners, information owners, information custodians, and users. Ownership of security also implies accountability for the protection of information assets and the management of security risks.

 Risk acceptance is the decision to accept the level of residual risk after applying security controls, and to tolerate the potential impact and consequences of a security incident. Approval of risk acceptance should be provided by business senior management, as they are the owners and accountable parties of the business processes, activities, and assets that are exposed to the risk. Business senior management should also have the authority and responsibility to allocate the resources, personnel, and budget to implement and monitor the risk acceptance decision, and to report and escalate the risk acceptance status to the board of directors or the executive management.

The chief risk officer (CRO) (A) is a senior executive who oversees the organization’s risk management function, and provides guidance, direction, and support for the identification, assessment, treatment, and monitoring of risks across the organization. The CRO may be involved in the risk acceptance process, such as by reviewing, endorsing, or advising the risk acceptance decision, but the CRO is not the ultimate approver of risk acceptance, as the CRO is not the owner or accountable party of the business processes, activities, and assets that are exposed to the risk.

The information security manager © is the manager who leads and coordinates the information security function, and provides guidance, direction, and support for the development, implementation, and maintenance of the information security program and activities. The information security manager may be involved in the risk acceptance process, such as by conducting the risk assessment, recommending the risk treatment options, or documenting the risk acceptance decision, but the information security manager is not the ultimate approver of risk acceptance, as the information security manager is not the owner or accountable party of the business processes, activities, and assets that are exposed to the risk.

The compliance officer (D) is the officer who oversees the organization’s compliance function, and provides guidance, direction, and support for the identification, assessment, implementation, and monitoring of the compliance requirements and obligations across the organization. The compliance officer may be involved in the risk acceptance process, such as by verifying, validating, or advising the risk acceptance decision, but the compliance officer is not the ultimate approver of risk acceptance, as the compliance officer is not the owner or accountable party of the business processes, activities, and assets that are exposed to the risk.

= According to the CISM Manual1, risk is defined as the combination of the probability of an event and its consequence. Therefore, determining the risk for a particular threat/vulnerability pair before controls are applied can be expressed as a function of the likelihood and impact, should a threat exploit a vulnerability. Likelihood is the probability or frequency of a threat occurring, while impact is the magnitude or severity of the harm or loss that would result from a threat exploiting a vulnerability. The higher the likelihood and impact, the higher the risk. The lower the likelihood and impact, the lower the risk.

The other options are not correct because they do not capture the full expression of risk. Option B only considers the impact, but not the likelihood, of a threat exploiting a vulnerability. Option C confuses the risk with the risk response, which is the action taken to reduce or mitigate the risk. Option D only considers the likelihood, but not the impact, of a threat attempting to exploit a vulnerability.

According to the CISM Review Manual, the first step an information security manager should take when a vulnerability has been disclosed is to conduct a risk assessment to determine the likelihood and impact of the vulnerability being exploited, and the appropriate response strategy. Performing a patch update, a penetration test or an impact assessment are possible subsequent steps, but not the first one.

 The FIRST step in developing an information security strategy is to perform a gap analysis based on the current state of the organization’s information security posture. A gap analysis is a systematic process of comparing the current state with the desired state and identifying the gaps or deficiencies that need to be addressed. A gap analysis helps to establish a baseline for the information security strategy, as well as to prioritize the actions and resources needed to achieve the strategic objectives. A gap analysis also helps to align the information security strategy with the organizational goals and strategies, as well as to ensure compliance with relevant standards and regulations. References = CISM Review Manual, 16th Edition, page 331; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 162

first step in developing an information security strategy is to conduct a risk-aware and comprehensive inventory of your company’s context, including all digital assets, employees, and vendors. Then you need to know about the threat environment and which types of attacks are a threat to your company1. This is similar to performing a gap analysis based on the current state3.

Chain of custody forms with points of contact are the best way to enable an organization to maintain legally admissible evidence because they document the sequence of control, transfer, and analysis of the evidence, and every person who handled it, the dates and times, and the purpose for each action1. They also ensure the authenticity and integrity of the evidence, and prevent tampering or loss1. Documented processes around forensic records retention are not sufficient to maintain legally admissible evidence because they do not track or verify the handling of the evidence. Robust legal framework with notes of legal actions are not sufficient to maintain legally admissible evidence because they do not record or validate the preservation of the evidence. Forensic personnel training that includes technical actions are not sufficient to maintain legally admissible evidence because they do not account or certify the custody of the evidence.
