Description

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. TOSS utilizes "pwquality" as a mechanism to enforce password complexity. Note that in order to require lower-case characters, without degrading the "minlen" value, the credit value must be expressed as a negative number in "/etc/security/pwquality.conf."

Check Text ( C-56514r824853_chk )
Verify the value for "lcredit" in "/etc/security/pwquality.conf" with the following command: $ sudo grep lcredit /etc/security/pwquality.conf lcredit = -1 If the value of "lcredit" is a positive number or is commented out, this is a finding.

Fix Text (F-56464r824854_fix)
Configure the operating system to enforce password complexity by requiring that at least one lower-case character be used by setting the "lcredit" option. Add the following line to /etc/security/pwquality.conf (or modify the line to have the required value): lcredit = -1
