RHEL 9 must ensure the password complexity module in the system-auth file is configured for three retries or less.

| 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. "pwquality" enforces complex password construction configuration and has the ability to limit brute-force attacks on the system. RHEL 9 uses "pwquality" as a mechanism to enforce password complexity. This is set in both: /etc/pam.d/password-auth /etc/pam.d/system-auth By limiting the number of attempts to meet the pwquality module complexity requirements before returning with an error, the system will audit abnormal attempts at password changes. | ||||

Details
Check Text (C-258091r1045185_chk)
Verify RHEL 9 is configured to limit the "pwquality" retry option to "3".
Check for the use of the retry option in the security directory with the following command:
$ grep -w retry /etc/security/pwquality.conf /etc/security/pwquality.conf.d/*.conf
retry = 3
If the value of "retry" is set to "0" or greater than "3", or is missing, this is a finding.
Fix Text (F-61756r1045184_fix)
Configure RHEL 9 to limit the "pwquality" retry option to "3".
Add or update the following line in the "/etc/security/pwquality.conf" file or a file in the "/etc/security/pwquality.conf.d/" directory to contain the "retry" parameter:
retry = 3
