= Reevaluation of risk is a vital aspect of the risk management process that helps organizations to identify and analyze new or evolving threats, vulnerabilities, and impacts on their assets, and implement the necessary controls to mitigate them. Reevaluation of risk is most critical when there is a change in the threat landscape, which refers to the external and internal factors that influence the likelihood and severity of potential attacks on the organization’s information assets. A change in the threat landscape may be caused by various factors, such as technological innovations, geopolitical events, cybercrime trends, regulatory changes, or organizational changes. A change in the threat landscape may introduce new risks or alter the existing risk profile of the organization, requiring a reassessment of the risk appetite, tolerance, and strategy. Reevaluation of risk helps the organization to adapt to the changing threat landscape and ensure that the information security program remains effective, efficient, and aligned with the business objectives.

Reevaluation of Risk | CISM Exam Question Answer | ISACA3

 The best indicator that information assets are classified accurately is appropriate prioritization of information risk treatment. Information asset classification is the process of assigning a level of sensitivity or criticality to information assets based on their value, impact, and legal or regulatory requirements. The purpose of information asset classification is to facilitate the identification and protection of information assets according to their importance and risk exposure. Therefore, if information assets are classified accurately, the organization can prioritize the information risk treatment activities and allocate the resources accordingly. The other options are not direct indicators of information asset classification accuracy, although they may be influenced by it. References = CISM Review Manual 15th Edition, page 671; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, Question ID: 1031

A gap analysis is a tool that helps to identify the current state of compliance and the desired state of compliance, as well as the actions needed to achieve the desired state. A gap analysis should be done before implementing any specific controls or solutions, such as encryption, data minimization, or ROI analysis.

After an intrusion has been detected and contained, the system should be recovered to a known and trusted state. The best practice for ensuring the integrity of the recovered system is to install the OS, patches, and application from the original source, such as the vendor’s website or media. This way, any malicious code or backdoors that may have been inserted by the intruder can be eliminated. Restoring the OS, patches, and application from a backup may not guarantee the integrity of the system, as the backup may have been compromised or outdated. Restoring the application and data from a forensic copy may preserve the evidence of the intrusion, but it may also reintroduce the vulnerability or malware that allowed the intrusion in the first place. Removing all signs of the intrusion from the OS and application may not be sufficient or feasible, as the intruder may have made subtle or hidden changes that are difficult to detect or undo.

The BEST practice for ensuring the integrity of the recovered system after an intrusion is to restore the OS, patches, and application from a backup. This will ensure that the system is in a known good state, without any potential residual malicious code or changes from the intrusion. Restoring from a backup also enables the organization to revert to a previous configuration that has been tested and known to be secure. This step should be taken prior to conducting a thorough investigation and forensic analysis to determine the cause and extent of the intrusion.
