Check: PHTN-67-000094
VMware vSphere 6.7 Photon OS STIG:
PHTN-67-000094
(in versions v1 r6 through v1 r1)
Title
The Photon operating system must configure sshd to limit the number of allowed login attempts per connection. (Cat II impact)
Discussion
By setting the login attempt limit to a low value, an attacker will be forced to reconnect frequently, which severely limits the speed and effectiveness of brute-force attacks.
Check Content
At the command line, execute the following command: # sshd -T|&grep -i MaxAuthTries Expected result: MaxAuthTries 2 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 "MaxAuthTries" line is uncommented and set to the following: MaxAuthTries 2 At the command line, execute the following command: # service sshd reload
