Title

The Ubuntu operating system must use a separate file system for /var. (Cat III impact)

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 Content

Verify that a separate file system/partition has been created for "/var". Check that a file system/partition has been created for "/var" with the following command: # grep /var /etc/fstab UUID=c274f65f /var ext4 noatime,nobarrier 1 2 If a separate entry for "/var" is not in use, this is a finding.

Fix Text

Migrate the "/var" path onto a separate file system.
