| 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. |
| Fix Text (F-16452r294220_fix) |
