Vulnerability Discussion
The use of separate file systems for different paths can protect the system from failures resulting from a file system becoming full or failing.
Check
Determine if the operating system is configured to have the "/var/log/audit" path is on a separate file system.
# grep /var/log/audit /etc/fstab
If no result is returned, or the operating system is not configured to have "/var/log/audit" on a separate file system, this is a finding.
Verify that "/var/log/audit" is mounted on a separate file system:
# mount | grep "/var/log/audit"
If no result is returned, or "/var/log/audit" is not on a separate file system, this is a finding.
Fix
Migrate the system audit data path onto a separate file system.
