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 /tmp filesystem is not intended to support devices, set this option to ensure that users cannot create a block or character special devices in /tmp.

Solution

- IF - a separate partition exists for /tmp.

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

Example:

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

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

 # mount -o remount /tmp
