Description
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 Text ( C-60173r887166_chk )
At the command line, run the following command:

# grep pam_cracklib /etc/pam.d/system-password|grep --color=always "ucredit=.."

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 include ucredit= <= -1, this is a finding.
Fix Text (F-60116r887167_fix)
Navigate to and open:

/etc/pam.d/system-password

Add the following, replacing any existing "pam_cracklib.so" line:

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

Note: On vCenter appliances, the equivalent file must be edited under "/etc/applmgmt/appliance", if one exists, for the changes to persist after a reboot.
