PHTN-67-000024 - The Photon operating system must require that new passwords are at least four characters different from the old password.

Information

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.

Solution

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.
