The next thing that the information security manager should do after identifying a large volume of old data that appears to be unused is to consult the record retention policy. The record retention policy is a document that defines the types, formats, and retention periods of data that the organization needs to keep for legal, regulatory, operational, or historical purposes. By consulting the record retention policy, the information security manager can determine if the old data is still required to be stored, archived, or disposed of, and how to do so in a secure and compliant manner.

Performing frequent backups and storing them offline is the best way to reduce the impact of a successful ransomware attack, as this allows the organization to restore its data and systems without paying the ransom or losing valuable information. Purchasing or renewing cyber insurance policies may help cover some of the costs and losses associated with a ransomware attack, but it does not prevent or mitigate the attack itself. Including provisions to pay ransoms in the information security budget may encourage more attacks and does not guarantee the recovery of the data or the removal of the malware. Monitoring the network and providing alerts on intrusions may help detect and respond to a ransomware attack, but it does not reduce the impact of a successful attack that has already encrypted or exfiltrated the data. References = CISM Review Manual 2023, page 1661; CISM Review Questions, Answers & Explanations Manual 2023, page 312; CISM Exam Overview - Vinsys3

The most concerning issue for the information security steering committee should be that no owners were identified for some risks in the risk register. This means that there is no clear accountability and responsibility for managing and mitigating those risks, and that the risks may not be properly addressed or monitored. The risk owners are the persons who have the authority and ability to implement the risk treatment options and to accept the residual risk. The risk owners should be identified and assigned for each risk in the risk register, and they should report the status and progress of the risk management activities to the information security steering committee.
