The primary objective of performing a vulnerability assessment following a business system update is to review the effectiveness of controls. A vulnerability assessment is a systematic review of security weaknesses in an information system. It evaluates if the system is susceptible to any known vulnerabilities, assigns severity levels to those vulnerabilities, and recommends remediation or mitigation, if and whenever needed1. A business system update is a process of modifying or enhancing an information system to improve its functionality, performance, security, or compatibility. A business system update may introduce new features, fix bugs, patch vulnerabilities, or comply with new standards or regulations2. Performing a vulnerability assessment following a business system update is important because it helps to:

* Review the effectiveness of controls that are implemented to protect the information sys-tem from threats and risks

* Identify any new or residual vulnerabilities that may have been introduced or exposed by the update

* Evaluate the impact and likelihood of potential incidents that may exploit the vulnerabili-ties

* Prioritize and implement appropriate actions to address the vulnerabilities

* Verify and validate the security posture and compliance of the updated information sys-tem

Therefore, the primary objective of performing a vulnerability assessment following a business system update is to review the effectiveness of controls that are designed to ensure the confidentiality, integrity, and availability of the information system and its data. The other options are not the primary objectives of performing a vulnerability as-sessment following a business system update. Determining operational losses is not an objective, but rather a possible consequence of not performing a vulnerability as-sessment or not addressing the identified vulnerabilities. Improving the change control process is not an objective, but rather a possible outcome of performing a vulnerability assessment and incorporating its results and recommendations into the change man-agement cycle. Updating the threat landscape is not an objective, but rather a prereq-uisite for performing a vulnerability assessment that requires using up-to-date sources of threat intelligence and vulnerability information.

Threat and vulnerability assessments are important primarily because they are the basis for setting control objectives. Control objectives are the desired outcomes of implementing security controls, and they should be aligned with the organization's risk appetite and business objectives. Threat and vulnerability assessments help to identify the potential sources and impacts of security incidents, and to prioritize the mitigation actions based on the likelihood and severity of the risks. By conducting threat and vulnerability assessments, the organization can establish the appropriate level and type of security controls to protect its information assets and reduce the residual risk to an acceptable level.Reference= CISM Review Manual (Digital Version), Chapter 3: Information Security Risk Management, Section 3.1: Risk Identification, p.115-1161. CISM Review Manual (Print Version), Chapter 3: Information Security Risk Management, Section 3.1: Risk Identification, p.115-1162. CISM ITEM DEVELOPMENT GUIDE, Domain 3: Information Security Program Development and Management, Task Statement 3.1, p.193.

Threat and vulnerability assessments are important PRIMARILY because they are the basis for setting control objectives. Control objectives are the desired outcomes or goals of implementing security controls in an information system. They are derived from the risk assessment process, which identifies and evaluates the threats and vulnerabilities that could affect the system's confidentiality, integrity and availability. By conducting threat and vulnerability assessments, an organization can determine the level of risk it faces and establish the appropriate control objectives to mitigate those risks.

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.Reference= 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.

Topic 3, Exam Pool C

A service provider is a third-party supplier that provides IT services or products to an organization. A service provider should comply with the organization's information security requirements, such as policies, standards, procedures, and controls, to ensure the confidentiality, integrity, and availability of the organization's data and systems. The best way to provide an information security manager with sufficient assurance that a service provider complies with the organization's information security requirements is to have the ability to audit the third-party supplier's IT systems and processes. An audit is a systematic and independent examination of evidence to determine the degree of conformity to predetermined criteria. An audit can verify the effectiveness and efficiency of the service provider's security controls, identify any gaps or weaknesses, and provide recommendations for improvement. An audit can also ensure that the service provider adheres to the contractual obligations and service level agreements (SLAs) with the organization. Therefore, option B is the most appropriate answer.

Option A is not the best answer because a live demonstration of the third-party supplier's security capabilities may not be comprehensive, objective, or reliable. A live demonstration may only show the positive aspects of the service provider's security, but not reveal any hidden or potential issues. A live demonstration may also be subject to manipulation or deception by the service provider.

Option C is not the best answer because third-party security control self-assessment (CSA) results may not be accurate, complete, or consistent. A self-assessment is a process where the service provider evaluates its own security controls against a set of criteria or standards. A self-assessment may be biased, subjective, or incomplete, as the service provider may not disclose or report all the relevant information or issues. A self-assessment may also vary in quality and scope depending on the service provider's expertise, resources, and methodology.

Option D is not the best answer because an independent review report indicating compliance with industry standards may not be sufficient or specific for the organization's information security requirements. An independent review is a process where an external party evaluates the service provider's security controls against a set of industry standards or best practices, such as ISO/IEC 27001, NIST CSF, PCI DSS, etc. An independent review report may provide a general overview of the service provider's security posture, but not address the organization's unique or specific security needs, risks, or expectations.An independent review report may also be outdated, limited, or generic, as the industry standards or best practices may not reflect the current or emerging security threats or trends.Reference= CISM Review Manual 15th Edition1, pages 257-258; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, QID 301.

An independent review report indicating compliance with industry standards BEST provides an information security manager with sufficient assurance that a service provider complies with the organization's information security requirements. This is because an independent review report is an objective and reliable source of evidence that the service provider has implemented and maintained effective security controls that meet the industry standards and best practices. An independent review report can also provide assurance that the service provider has addressed any gaps or weaknesses identified in previous audits or assessments.

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.Reference= 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.

To help ensure that an information security training program is MOST effective, its contents should be based on employees' roles, as different roles have different information security responsibilities, needs, and risks. A role-based training program can tailor the content and delivery methods to suit the specific learning objectives and outcomes for each role, and enhance the relevance and retention of the information security knowledge and skills. Based on recent incidents is not the best answer, as it may not cover all the information security topics that are important for the organization, and may not address the root causes or preventive measures of the incidents. Based on employees' roles is more comprehensive and proactive than based on recent incidents. Aligned to business processes is not the best answer, as it may not reflect the individual roles and responsibilities of the employees, and may not cover all the information security aspects that are relevant for the organization. Based on employees' roles is more specific and personalized than aligned to business processes. Focused on information security policy is not the best answer, as it may not provide sufficient details or examples to help the employees understand and apply the information security policy in their daily work.Based on employees' roles is more practical and engaging than focused on information security policy.Reference= CISM Review Manual, 16th Edition, page 2241; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 1002

To help ensure that an information security training program is MOST effective, its contents should be based on employees' roles. This is because different roles have different responsibilities and access levels to information and systems, and therefore face different types of threats and risks. By tailoring the training content to the specific needs and expectations of each role, the training program can increase the relevance and retention of the information security knowledge and skills for the employees. Role-based training can also help employees understand their accountability and obligations for protecting information assets in their daily tasks

When developing a categorization method for security incidents, the categories must have agreed-upon definitions. This means that the categories should be clear, consistent, and understandable for all the parties involved in the incident response process, such as the incident handlers, the stakeholders, the management, and the external authorities. Having agreed-upon definitions for the categories can help to ensure that the incidents are classified and reported accurately, that the appropriate actions and resources are allocated, and that the communication and coordination are effective. Aligning with industry standards, creating by the incident handler, and aligning with reporting requirements are not mandatory for developing a categorization method for security incidents, although they may be desirable or beneficial depending on the context and objectives of the organization. Aligning with industry standards can help to adopt best practices and benchmarks for incident response, but it may not be feasible or suitable for all types of incidents or organizations. Creating by the incident handler can allow for flexibility and customization of the categories, but it may also introduce inconsistency and ambiguity if the definitions are not shared or agreed upon by others.Aligning with reporting requirements can help to comply with legal or contractual obligations, but it may not cover all the aspects or dimensions of the incidents that need to be categorized.Reference= CISM Review Manual, 16th Edition, pages 200-2011; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 822

When developing a categorization method for security incidents, the categories MUST have agreed-upon definitions. This is because having clear and consistent definitions for each category of incidents will help to ensure a common understanding and communication among the incident response team and other stakeholders. It will also facilitate the accurate and timely identification, classification, reporting and analysis of incidents. Having agreed-upon definitions will also help to avoid confusion, ambiguity and inconsistency in the incident management process

= Information security governance is the process of establishing and maintaining the policies, standards, frameworks, and best practices that guide the information security program of an organization. Information security governance helps to ensure that the information security program meets the needs of the business by aligning it with the organization's risk appetite, objectives, and strategy. Information security governance also helps to coordinate and integrate various assurance functions, such as risk management, compliance, audit, and incident response, to provide a holistic view of the information security posture.Information security governance is essential for achieving a positive return on investment (ROI) from information security investments, as well as for enhancing the trust and confidence of internal and external stakeholders.References= CISM Review Manual (Digital Version), Chapter 1: Introduction to Information Security Management, Section 1.1: Overview of Information Security Management1.CISM Review Manual (Print Version), Chapter 1: Introduction to Information Security Management, Section 1.1: Overview of Information Security Management2. CISM ITEM DEVELOPMENT GUIDE, Domain 1: Information Security Governance, Task Statement 1.1, p.193.

Information security governance is MOST important to have in place to help ensure an organization's cybersecurity program meets the needs of the business. This is because information security governance provides the strategic direction, oversight and accountability for the cybersecurity program. It also ensures that the program aligns with the business objectives, risk appetite and compliance requirements of the organization. Information security governance involves defining roles and responsibilities, establishing policies and standards, setting goals and metrics, allocating resources and monitoring performance of the cybersecurity program.

A risk register is a document that records and tracks the information security risks facing an organization, such as their sources, impacts, likelihoods, responses, and statuses. A risk register provides the most comprehensive insight into ongoing threats facing an organization, as it covers both internal and external threats, as well as their current and potential effects on the organization's assets, processes, and objectives. A risk register also helps to prioritize and monitor the risk mitigation actions and controls, and to communicate the risk information to relevant stakeholders. Therefore, option B is the most appropriate answer.

Option A is not the best answer because a business impact analysis (BIA) is a process that identifies and evaluates the critical business functions, assets, and dependencies of an organization, and assesses their potential impact in the event of a disruption or loss. A BIA does not provide a comprehensive insight into ongoing threats facing an organization, as it focuses more on the consequences of the threats, rather than their sources, likelihoods, or responses. A BIA is mainly used to support the business continuity and disaster recovery planning, rather than the information security risk management.

Option C is not the best answer because penetration testing is a method of simulating a malicious attack on an organization's IT systems or networks, to evaluate their security posture and identify any vulnerabilities or weaknesses that could be exploited by real attackers. Penetration testing does not provide a comprehensive insight into ongoing threats facing an organization, as it only covers a specific scope, target, and scenario, rather than the whole range of threats, sources, and impacts. Penetration testing is mainly used to validate and improve the technical security controls, rather than the information security risk management.

Option D is not the best answer because vulnerability assessment is a process of scanning and analyzing an organization's IT systems or networks, to detect and report any flaws or gaps that could pose a security risk. Vulnerability assessment does not provide a comprehensive insight into ongoing threats facing an organization, as it only covers the technical aspects of the threats, rather than their business, legal, or regulatory implications.Vulnerability assessment is mainly used to identify and remediate the security weaknesses, rather than the information security risk management.Reference= CISM Review Manual 15th Edition1, pages 258-259; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, QID 306.

A risk register provides the MOST comprehensive insight into ongoing threats facing an organization. This is because a risk register is a document that records and tracks the identified risks, their likelihood, impact, mitigation strategies, and status. A risk register helps an organization to monitor and manage the threats that could affect its objectives, assets, and operations. A risk register also helps an organization to prioritize its response efforts and allocate its resources accordingly.
