OL 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. OL 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-271612r1091548_chk)
Verify that OL 9 is configured to limit the "pwquality" retry option to "3".
Check for the use of the "pwquality" retry option in the system-auth file with the following command:
$ grep pam_pwquality /etc/pam.d/system-auth
password required pam_pwquality.so 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-75569r1091547_fix)
Configure OL 9 to limit the "pwquality" retry option to "3".
Add the following line to the "/etc/pam.d/system-auth" file (or modify the line to have the required value):
password required pam_pwquality.so retry=3
