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.

Check the file systems that are mounted at boot time with the following command:

# more /etc/fstab

UUID=2bc871e4-e2a3-4f29-9ece-3be60c835222 /mnt/usbflash vfat noauto,owner,ro,nosuid 0 0

If a file system found in "/etc/fstab" refers to removable media and it does not have the "nosuid" option set, this is a finding.
