cyberstrikeus 2.12 Add noexec Option to Removable Media Partitions (Not Scored)
Profile Applicability
- Level 1
Description
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.
Audit Procedure
Using Command Line
grep <each removable media mountpoint> /etc/fstab
Verify that noexec is an option.
Expected Result
The noexec option should be present in the mount options for each removable media mountpoint.
Remediation
Using Command Line
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.
Default Value
By default, the noexec option is not set on removable media partitions.
