Fix Recommendation

Configure the "/etc/fstab" to use the "nosuid" option on file systems that are associated with removable media.

Check Contents

Verify file systems that are used for removable media are mounted with the "nosuid" option with the following command:

$ cat /etc/fstab

UUID=0cb43738-b102-48f8-9174-061d8ee537b8 /mnt/usbdrive vfat noauto,owner,ro,nosuid,nodev,noexec 0 0
