Ensure nodev option set on removable media partitions

MediumLevel 1Manual reviewros

Description

The nodev mount option specifies that the filesystem cannot contain special devices. Manual review against site policy. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Run the following command and verify that the nodev option is set on all removable media partitions. # mount

How it is fixed

Fix method: Guidance or infrastructure patch

Edit the /etc/fstab file and add nodev to the fourth field (mounting options) of all removable media partitions. Look for entries that have mount points that contain words such as floppy or cdrom. See the fstab(5) manual page for more information.
