Vulnerability Discussion

Verify the operating system disables the ability to automount devices.

Determine if automounter service is active with the following command:

$ sudo systemctl status autofs

autofs.service - Automounts filesystems on demand
Loaded: loaded (/usr/lib/systemd/system/autofs.service; disabled)
Active: inactive (dead)

If the "autofs" status is set to "active" and is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
