Check: PHTN-67-000029
VMware vSphere 6.7 Photon OS STIG:
PHTN-67-000029
(in versions v1 r6 through v1 r1)
Title
The Photon operating system must prohibit password reuse for a minimum of five generations. (Cat II impact)
Discussion
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.
Check Content
At the command line, execute the following command: # grep pam_pwhistory /etc/pam.d/system-password|grep --color=always "remember=." Expected result: password required pam_pwhistory.so enforce_for_root use_authtok remember=5 retry=3 If the output does not match the expected result, this is a finding.
Fix Text
Open /etc/applmgmt/appliance/system-password with a text editor. Add the following line after the last auth statement: password required pam_pwhistory.so enforce_for_root use_authtok remember=5 retry=3 Save and close.
