Check: PHTN-67-000083
VMware vSphere 6.7 Photon OS STIG:
PHTN-67-000083
(in versions v1 r6 through v1 r1)
Title
The Photon operating system must configure sshd to disallow Generic Security Service Application Program Interface (GSSAPI) authentication. (Cat II impact)
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.
Check Content
At the command line, execute 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
Open /etc/ssh/sshd_config with a text editor. Ensure that the "GSSAPIAuthentication" line is uncommented and set to the following: GSSAPIAuthentication no At the command line, execute the following command: # service sshd reload
