Which method is used to ensure users cannot tamper with logs of security events?

The method that best ensures users cannot tamper with logs of security events is access controls. Access controls involve implementing permissions and restrictions that determine who is allowed to view or modify logs. By restricting access to only authorized personnel, the integrity of the logs can be maintained. This prevents unauthorized users from altering or deleting critical security event logs, thereby providing a reliable audit trail for security investigations.

While encryption can protect the contents of the logs from unauthorized access, it does not inherently prevent logged events from being manipulated by users with sufficient access rights. Time stamping is important for verifying when events occurred but does not address the capability of users to alter logs. Redundancy involves creating copies or backups of logs to ensure availability, but it does not inherently prevent tampering either. Access controls provide the necessary safeguards to ensure that logs remain authentic and trustworthy.
