The Photon operating system must enforce password complexity on the root account.

Description
Password complexity rules must apply to all accounts on the system, including root. Without specifying the "enforce_for_root flag", "pam_cracklib" does not apply complexity rules to the root user. While root users can find ways around this requirement, given its superuser power, it is necessary to attempt to force compliance.

At the command line, run the following command: # grep pam_cracklib /etc/pam.d/system-password\|grep --color=always "enforce_for_root" 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 "enforce_for_root", this is a finding.

Fix Text (F-60197r887410_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.
