Description

Audit logs are most useful when accessible by date, rather than size. This can be accomplished through a combination of an audit log rotation cron job, setting a reasonable number of logs to keep, and configuring auditd to not rotate the logs on its own. This ensures audit logs are accessible to the information system security officer (ISSO) in the event of a central log processing failure. If another solution is not used to rotate auditd logs, auditd can be configured to rotate logs.

Check Text ( C-60203r887256_chk )
At the command line, run the following command: # grep "^max_log_file_action" /etc/audit/auditd.conf Example result: max_log_file_action = IGNORE If logs are rotated outside of auditd with a tool such as logrotated, and this setting is not set to "IGNORE", this is a finding. If logs are NOT rotated outside of auditd, and this setting is not set to "ROTATE", this is a finding.

Fix Text (F-60146r887257_fix)
Navigate to and open: /etc/audit/auditd.conf Add or change the "max_log_file_action" line as follows: max_log_file_action = IGNORE Note: This can also be set to "ROTATE" if another tool is not used to rotate auditd logs. At the command line, run the following commands: # killproc auditd -TERM # systemctl start auditd
