 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 correct answer is C because standards define mandatory minimum requirements and baselines that must be followed to comply with policy. In information security governance, policies state management intent and high-level requirements, while standards translate those requirements into specific mandatory control baselines. For example, a password policy may state that access must be protected, while a password standard defines minimum length, complexity, history, and expiration requirements. Procedures provide step-by-step instructions for performing tasks, and guidelines provide recommended but usually nonmandatory advice. The question asks specifically for the minimum technical baseline, which is the function of standards. Standards ensure consistency across systems, technologies, and business units by defining the minimum acceptable level of security. This supports governance, compliance, and control implementation. In CISM practice, policies, standards, procedures, and guidelines form a hierarchy, with standards serving as enforceable requirements derived from policy.

The first thing that should be done when a SIEM flags a potential event is A. Validate the event is not a false positive. This is because a false positive is an event that is incorrectly identified as malicious or suspicious by the SIEM, when in fact it is benign or normal. False positives can waste the time and resources of the security team, and reduce the trust and confidence in the SIEM system. Therefore, it is important to verify the accuracy and validity of the event before initiating any further actions, such as incident response, escalation, or compensating controls. Validation can be done by analyzing the event data, comparing it with the baseline or normal behavior, and checking for any anomalies or indicators of compromise.
