SV-100435r1_rule The SLES for vRealize must immediately notify the SA and ISSO (at a minimum) when allocated audit record storage volume reaches 75% of the repository maximum audit record storage capacity.

Vulnerability discussion

If security personnel are not notified immediately when storage volume reaches 75% utilization, they are unable to plan for audit record storage capacity expansion.

Check content

Check "/etc/audit/auditd.conf" for the" space_left_action" 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 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 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

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
