| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-256547 | PHTN-30-000078 | SV-256547r991589_rule | CCI-000366 | medium |
| Description | ||||
| GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through Secure Shell (SSH) exposes the system's GSSAPI to remote hosts, increasing the attack surface of the system. | ||||

Details
Check Text (C-256547r991589_chk)
At the command line, run the following command:
# sshd -T|&grep -i GSSAPIAuthentication
Expected result:
GSSAPIAuthentication no
If the output does not match the expected result, this is a finding.
Fix Text (F-60165r887314_fix)
Navigate to and open:
/etc/ssh/sshd_config
Ensure the "GSSAPIAuthentication" line is uncommented and set to the following:
GSSAPIAuthentication no
At the command line, run the following command:
# systemctl restart sshd.service
