= The method of operation used by the attacker is the most useful information for an information security manager when conducting a post-incident review of an attack. This information can help identify the root cause of the incident, the vulnerabilities exploited, the impact and severity of the attack, and the effectiveness of the existing security controls. The method of operation can also provide insights into the attacker’s motives, skills, and resources, which can help improve the organization’s threat intelligence and risk assessment. The cost of the attack to the organization, the location of the attacker, and the details from IDS logs are all relevant information for a post-incident review, but they are not as useful as the method of operation for improving the incident handling process and preventing future attacks. References = CISM Review Manual 2022, page 316; CISM Item Development Guide 2022, page 9; ISACA CISM: PRIMARY goal of a post-incident review should be to?

= Patch management is the process of applying updates to software and hardware systems to fix security vulnerabilities and improve functionality. Patch management is one of the best ways to prevent the exploitation of system vulnerabilities, as it reduces the attack surface and closes the gaps that attackers can exploit. Patch management also helps to ensure compliance with security standards and regulations, and maintain the performance and availability of systems.

Intrusion detection is the process of monitoring network or system activities for signs of malicious or unauthorized behavior. Intrusion detection can help to detect and respond to attacks, but it does not prevent them from happening in the first place. Log monitoring is the process of collecting, analyzing and reviewing log files generated by various systems and applications. Log monitoring can help to identify anomalies, errors and security incidents, but it does not prevent them from occurring. Antivirus software is the program that scans files and systems for viruses, malware and other malicious code. Antivirus software can help to protect systems from infection, but it does not prevent the exploitation of system vulnerabilities that are not related to malware.

Therefore, patch management is the best security process to prevent the exploitation of system vulnerabilities, as it addresses the root cause of the problem and reduces the risk of compromise. References = CISM Review Manual, 16th Edition eBook | Digital | English1, Chapter 4: Information Security Program Development and Management, Section 4.3: Information Security Program Resources, Subsection 4.3.1: Information Security Infrastructure and Architecture, Page 204.

 According to the CISM Review Manual, the information security manager’s best course of action when security controls may no longer be adequate due to changes in the organization’s environment is to perform a new risk assessment. A risk assessment is a process of identifying, analyzing, and evaluating the risks that affect the organization’s information assets and business processes. A risk assessment should be performed periodically or whenever there are significant changes in the organization’s environment, such as new threats, vulnerabilities, technologies, regulations, or business objectives. A risk assessment helps to determine the current level of risk exposure and the adequacy of existing security controls. A risk assessment also provides the basis for developing or updating the risk treatment plan, which defines the appropriate risk responses, such as implementing new or enhanced security controls, transferring the risk to a third party, accepting the risk, or avoiding the risk.

The other options are not the best course of action in this scenario. Reviewing the previous risk assessment and countermeasures may not reflect the current state of the organization’s environment and may not identify new or emerging risks. Evaluating countermeasures to mitigate new risks may be premature without performing a new risk assessment to identify and prioritize the risks. Transferring the new risk to a third party may not be feasible or cost-effective without performing a new risk assessment to evaluate the risk level and the available risk transfer options.

 A controls audit is the best indicator of an organization’s information security status, as it provides an independent and objective assessment of the design, implementation, and effectiveness of the information security controls. A controls audit can also identify the strengths and weaknesses of the information security program, as well as the compliance with the policies, standards, and regulations. A controls audit can cover various aspects of information security, such as governance, risk management, incident management, business continuity, and technical security. A controls audit can be conducted by internal or external auditors, depending on the scope, purpose, and frequency of the audit.

The other options are not as good as a controls audit, as they do not provide a comprehensive and holistic view of the information security status. Intrusion detection log analysis is a technique to monitor and analyze the network or system activities for signs of unauthorized or malicious access or attacks. It can help to detect and respond to security incidents, but it does not measure the overall performance or maturity of the information security program. Threat analysis is a process to identify and evaluate the potential sources, methods, and impacts of threats to the information assets. It can help to prioritize and mitigate the risks, but it does not verify the adequacy or functionality of the information security controls. Penetration test is a simulated attack on the network or system to evaluate the vulnerability and exploitability of the information security defenses. It can help to validate and improve the technical security, but it does not assess the non-technical aspects of information security, such as governance, policies, or awareness. References =
