Rule version SLEM-05-231050 · STIG v1 · 2026-08-20

Discussion

Automatically mounting file systems permits easy introduction of unknown devices, thereby facilitating malicious activity.

Check

Verify SLEM 5 disables the ability to automount devices.

Verify the automounter service is installed with the following command:

     > sudo zypper se autofs

If it is installed, verify the 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

Configure SLEM 5 to disable the ability to automount devices.

Turn off the automount service with the following command:

     > sudo systemctl stop autofs
     > sudo systemctl disable autofs
