Discussion

Automatically mounting file systems permits easy introduction of unknown devices, thereby facilitating malicious activity. Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163

Check Content

Verify the SUSE operating system disables the ability to automount devices.

Check to see if automounter service is active with the following command:

> 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" this is a finding.

Fix Text

Configure the SUSE operating system to disable the ability to automount devices.

Turn off the automount service with the following commands:

> systemctl stop autofs
> systemctl disable autofs
