SV-40715r1_rule The SSH client must not permit GSSAPI authentication unless needed.

Vulnerability discussion

GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through SSH exposes the system’s GSSAPI to remote hosts, increasing the attack surface of the system. GSSAPI authentication must be disabled unless needed.

Check content

Fix text

Edit the /etc/ssh/ssh_config file and remove the GSSAPIAuthentication setting or change the GSSAPIAuthentication setting to "no".

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.
