PHTN-40-000037 The Photon operating system must enforce password complexity by requiring that at least one numeric character be used.

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.

Password complexity is one factor of several that determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.

Solution

Navigate to and open:

/etc/pam.d/system-password

Configure the pam_pwquality.so line to have the "dcredit" option set to "-1" as follows:

password requisite pam_pwquality.so dcredit=-1 ucredit=-1 lcredit=-1 ocredit=-1 minlen=15 difok=8 enforce_for_root dictcheck=1

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.
