Check Text ( C-36435r1_chk )
Check for a crontab entry that rotates audit logs. # crontab -l If any cron job to rotate audit logs is found, this is not a finding. Otherwise, query the SA. If there is a process that automatically rotates audit logs, this is not a finding. If the SA manually rotates audit logs, this is still a finding, because if the SA is not there, it will not be accomplished. If the audit output is not archived daily, to tape or disk, this is a finding. This can be ascertained by looking at the audit log directory and, if more than one file is there, or if the file does not have today's date, this is a finding.
