====== 1.1.20 Ensure noexec option set on removable media partitions (Not Scored) ======
=====Profile Applicability=====  
<code>
Level 1 - Server 
Level 1 - Workstation
</code>
=====Description=====
The ''noexec'' mount option specifies that the filesystem cannot contain executable binaries.
=====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.
=====Audit===== 
Run the following command and verify that the ''noexec'' option is set on all removable media partitions.
<Code:bash>
# mount
</Code>
=====Remediation===== 
Edit the ''/etc/fstab'' file and add ''noexec'' 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.
