Details

Set noexec on removable media to prevent programs from executing from the removable

media.

*Rationale*

Setting this option on a file system prevents users from executing programs from the

removable media. This deters users from being able to introduce potentially malicious

software on the system.

Solution

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