| Description | ||||
| Rotate audit logs daily to preserve audit file system space and to conform to the DoD/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 any "crontab" entries that rotate audit logs:
# crontab -l
30 23 * * * /root/logrotate.sh #Daily log rotation script
If such a cron job is found, this is not a finding.
Otherwise, query the SA.
If there is a process automatically rotating audit logs, this is not a finding.
If the SA manually rotates audit logs, this is a finding.
If the audit output is not archived daily, to tape or disk, this is a finding.
Review the audit log directory.
If more than one file is there, or if the file does not have today's date, this is a finding.
