Check: PHTN-67-000024
VMware vSphere 6.7 Photon OS STIG:
PHTN-67-000024
(in versions v1 r6 through v1 r1)
Title
The Photon operating system must require that new passwords are at least four characters different from the old password. (Cat II impact)
Discussion
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks.
Check Content
At the command line, execute the following command: # grep pam_cracklib /etc/pam.d/system-password|grep --color=always "difok=." Expected result: password requisite pam_cracklib.so dcredit=-1 ucredit=-1 lcredit=-1 ocredit=-1 minlen=8 minclass=4 difok=4 retry=3 maxsequence=0 enforce_for_root 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. Comment out any existing "pam_cracklib.so" line and add the following: password requisite pam_cracklib.so dcredit=-1 ucredit=-1 lcredit=-1 ocredit=-1 minlen=8 minclass=4 difok=4 retry=3 maxsequence=0 enforce_for_root Save and close.
