====== 1.1.16 Ensure noexec option set on /dev/shm partition (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 shared memory. This deters users from introducing potentially malicious software on the system.
=====Audit===== 
Run the following command and verify that the ''noexec'' option is set on ''/run/shm''. \\
<Code:bash>
# mount | grep /dev/shm 
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime)
</Code>
=====Remediation===== 
Edit the ''/etc/fstab'' file and add ''noexec'' to the fourth field (mounting options) for the ''/dev/shm'' partition. See the ''fstab(5)'' manual page for more information. \\ 
Run the following command to remount ''/dev/shm'': \\
<Code:bash>
# mount -o remount,nodev /dev/shm
</Code>
