Warning! Audit Deprecated

This audit has been deprecated and will be removed in a future update.

View Next Audit Version

Information

The nodev mount option specifies that the filesystem cannot contain special devices.

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.

Solution

- IF - a separate partition exists for /var.

Edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /var partition.

Example:

<device> /var <fstype> defaults,rw,nosuid,nodev,noexec,relatime 0 0

Run the following command to remount /var with the configured options:

# mount -o remount /var
