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
Verify that a separate file system/partition has been created for the system audit data path with the following command:
Note: "/var/log/audit" is used as the example as it is a common location.
$ sudo grep /var/log/audit /etc/fstab
UUID=3645951a /var/log/audit ext4 defaults 1 2
If an entry for "/var/log/audit" does not exist, ask the System Administrator if the system audit logs are being written to a different file system/partition on the system and then grep for that file system/partition.
If a separate file system/partition does not exist for the system audit data path, this is a finding.
Fix
Migrate the system audit data path onto a separate file system.
