Rotate audit logs daily to preserve audit file system space and to conform to the DISA requirement. If it is not rotated daily and moved to another location, then there is more of a chance for the compromise of audit data by malicious users.
Check for a "logrotate" entry that rotates audit logs. # ls -l /etc/logrotate.d/audit If it exists, check for the presence of the "daily" rotate flag: # egrep "daily" /etc/logrotate.d/audit The command should produce a "daily" entry in the logrotate file for the audit daemon. If the "daily" entry is missing, this is a finding.
Create or edit the /etc/logrotate.d/audit file and add the "daily" entry, such as:
/var/log/audit/audit.log {
compress
