OL09-00-001005 - OL 9 must enforce password complexity by requiring that at least one uppercase 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. Requiring a minimum number of uppercase characters makes password guessing attacks more difficult by ensuring a larger search space.Solution
Configure OL 9 to enforce password complexity by requiring that at least one uppercase character is used by setting the "ucredit" option.Add the following line to /etc/security/pwquality.conf (or modify the line to have the required value):
ucredit = -1
