The main goal of a cybersecurity risk assessment is to gain visibility into the organization’s current security posture, identify vulnerabilities, evaluate threats, and understand the potential impact of various risks.

“Risk assessments provide an understanding of the organization’s threat landscape, asset vulnerabilities, and residual risk exposure.”

— CISM Review Manual 15th Edition, Chapter 2: Risk Assessment and Risk Identification*

While assessments support reporting and compliance, their primary role is situational awareness.

Data classification is the sole responsibility of the client organization when adopting a Software as a Service (SaaS) model. Data classification is the process of categorizing data based on its sensitivity, value and criticality to the organization. Data classification helps to determine the appropriate level of protection, access control and retention for different types of data. Data classification is an essential part of data governance and risk management, as it enables the organization to comply with legal and regulatory requirements, protect its intellectual property and reputation, and optimize its data storage and usage costs.

In a SaaS model, the client organization has the least control and responsibility over the cloud infrastructure, platform and application, as these are fully managed by the cloud service provider (CSP). The client organization only has control and responsibility over its own data and users. Therefore, the client organization is responsible for defining and implementing data classification policies and procedures, and ensuring that its data is properly labeled and handled according to its classification level. The client organization is also responsible for educating its users about the importance of data classification and the best practices for data security and privacy.

The other options are not the sole responsibility of the client organization in a SaaS model, as they are either shared with or delegated to the CSP. Host patching, penetration testing and infrastructure hardening are all related to the security and maintenance of the cloud infrastructure and platform, which are the responsibility of the CSP in a SaaS model. The CSP is expected to provide regular updates, patches and fixes to the host operating system, network and application components, and to conduct periodic security assessments and audits to identify and remediate any vulnerabilities or weaknesses in the cloud environment. The client organization may have some responsibility to monitor and verify the CSP’s performance and compliance with the service level agreement (SLA) and the cloud security standards and regulations, but it does not have direct control or access to the cloud infrastructure and platform. References =

The correct answer is B because a documented incident response plan provides the structured guidance needed for effective and timely response. The plan defines roles, responsibilities, escalation paths, communication procedures, severity classifications, containment strategies, evidence handling, notification requirements, and recovery coordination. Without a documented plan, response activities may be delayed, inconsistent, duplicated, or incomplete. Involving internal and external stakeholders is important, but stakeholder involvement must be organized through the incident response plan. Appointing a forensic specialist may be necessary for certain investigations, but not every incident requires forensic expertise. A SIEM solution is useful for monitoring and detection, but technology alone does not ensure that people know how to respond. CISM incident management principles emphasize preparation, documented procedures, communication, role clarity, and repeatable response processes. A documented plan enables responders to act quickly and consistently under pressure. Therefore, having a documented incident response plan in place best supports effective and timely incident response.

 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
