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. TOSS 5 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.

Check Text (C-282445r1200315_chk)

Verify TOSS 5 is configured to limit the "pwquality" retry option to "3". Verify the use of the "pwquality" retry option in the "system-auth file" using the following command: $ cat /etc/pam.d/system-auth | grep pam_pwquality 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-86911r1200314_fix)

Configure TOSS 5 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
