Check "/etc/audit/auditd.conf" file for the "space_left_action" parameter with the following command: # cat /etc/audit/auditd.conf \| grep space_left_action If the "space_left_action" parameter is missing, set to "ignore", set to "suspend", set to "single", set to "halt", or is blank, this is a finding Expected Result: space_left_action = SYSLOG Notes: If the "space_left_action" parameter is set to "exec" the system executes a designated script. If this script informs the SA of the event, this is not a finding. If the "space_left_action" parameter is set to "email" and the "action_mail_acct" parameter is not set to the email address of the system administrator, this is a finding. The "action_mail_acct" parameter, if missing, defaults to "root". Note that if the email address of the system administrator is on a remote system "sendmail" must be available.

Fix Text (F-42790r662244_fix)
Set the "space_left_action" parameter to the valid setting "SYSLOG", by running the following command: # sed -i "/^[^#]*space_left_action/ c\admin_space_left_action = SYSLOG" /etc/audit/auditd.conf Restart the audit service: # service auditd restart
