AIX audit logs must be rotated daily.

Rotate audit logs daily to preserve audit file system space and to conform to the DoW/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.

Configure a cron job or other automated process to rotate the audit logs on a daily basis.
