Description: The `nodev` mount option specifies that the filesystem cannot contain special devices. Rationale: Since the /var filesystem is not intended to support devices, set this option to ensure
that users cannot create a block or character special devices in /var . Audit: Verify that the `nodev` option is set if a `/var` partition exists.Run the following command and verify that nothing is returned:# mount | grep -E '\s/var\s' | grep -v nodev Remediation: Edit the `/etc/fstab` file and add `nodev` to the fourth field (mounting options) for the `/var` partition. See the `fstab(5)` manual page for more information.# mount -o remount,nodev /var.
Parameter:
[yes/no]
Technical Mechanism:
Run the following command to remount /var:
# mount -o remount,nodev /var
