Vulnerability discussion

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" and is not documented with the Information System Security Officer (ISSO) as an operational requirement, 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 command: # systemctl stop autofs # systemctl disable autofs If "autofs" is required for Network File System (NFS), it must be documented with the ISSO.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
