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.
