Add nodev Option to Removable Media Partitions
Medium Severity
The
nodev
mount option prevents files from being interpreted as character or block devices. Legitimate character and block devices should exist only in the
/dev
directory on the root partition or within chroot jails built for system services. Add the
nodev
option to the fourth column of
/etc/fstab
for the line which controls mounting of any removable media partitions.
