Title
The audit system must take appropriate action when the audit storage volume is full. (Cat II impact)
Discussion
Taking appropriate action in case of a filled audit storage volume will minimize the possibility of losing audit records.
Check Content
Inspect "/etc/audit/auditd.conf" and locate the following line to determine if the system is configured to take appropriate action when the audit storage volume is full: # grep disk_full_action /etc/audit/auditd.conf disk_full_action = [ACTION] If the system is configured to "suspend" when the volume is full or "ignore" that it is full, this is a finding.
Fix Text
The "auditd" service can be configured to take an action when disk space starts to run low. Edit the file "/etc/audit/auditd.conf". Modify the following line, substituting [ACTION] appropriately: disk_full_action = [ACTION] Possible values for [ACTION] are described in the "auditd.conf" man page. These include: "ignore" "syslog" "exec" "suspend" "single" "halt" Set this to "syslog", "exec", "single", or "halt".
