OL09-00-001120 - OL 9 must enforce password complexity by requiring that at least one special 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. OL 9 uses "pwquality" as a mechanism to enforce password complexity. Note that to require special characters without degrading the "minlen" value, the credit value must be expressed as a negative number in "/etc/security/pwquality.conf".Solution
Configure OL 9 to enforce password complexity by requiring at least one special character be used by setting the "ocredit" option.Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value):
ocredit = -1
