Effective Measures to Mitigate Ransomware Impact

B.

The incident management process involves the detection, containment, and resolution of security incidents. The goal of incident management is to minimize the impact of security incidents and restore normal business operations as soon as possible. In this case, the IS auditor has identified that client information was lost due to a ransomware attack. To minimize the impact of future occurrences, the most effective solution should be identified.

Option A: Changing access to client data to read-only would not prevent the occurrence of ransomware attacks. This option may limit the impact of future attacks, but it would also limit the ability of authorized users to modify or update the data when necessary.

Option B: Improving the ransomware awareness program could be a viable solution, as it would increase the awareness of employees about the risks associated with ransomware and how to identify and report suspicious activities. However, it does not guarantee prevention.

Option C: Backing up client data more frequently would enable the organization to restore data more easily in case of a ransomware attack. This solution would minimize the impact of future occurrences and reduce the likelihood of losing critical data.

Option D: Monitoring all client data changes would provide additional visibility into any unauthorized access or modifications to the client data. This solution could help identify any anomalies early on, but it may not prevent ransomware attacks from occurring.

Based on the above analysis, the most effective solution to minimize the impact of future occurrences is Option C: Back up client data more frequently. This option would ensure that critical data is always available in case of a ransomware attack and would reduce the likelihood of data loss. However, it is recommended to implement a combination of options, including improving awareness and monitoring for potential attacks, in order to enhance overall security posture.
