| Check the contents of the "/var/log/audit/audit.log" file. HYCU also maintains Event (Audit) information in the HYCU Web UI Events menu. Verify the audit log contains records showing when the execution of privileged functions occurred. If the audit log is not configured or does not have the required contents, this is a finding. |
