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.

Check Text (C-269390r1155274_chk)

Verify AlmaLinux OS 9 enforces password complexity by requiring at least one special character with the following command: $ grep -r ocredit /etc/security/pwquality.conf* /etc/security/pwquality.conf.d/stig.conf:ocredit = -1 If the value of "ocredit" is a positive number, is not set, is commented out, or if conflicting results are returned, this is a finding.

Fix Text (F-73322r1049611_fix)

Configure AlmaLinux OS 9 to enforce password complexity by requiring at least one special character be used by setting the "ocredit" option. Add or update the following line in the "/etc/security/pwquality.conf" file or a configuration file in the "/etc/security/pwquality.conf.d/" directory: ocredit = -1 Remove any configurations that conflict with the above value.
