Fix Recommendation

Configure the operating system to use "pwquality" to enforce password complexity rules.

Add the following line to "/etc/pam.d/system-auth" (or modify the line to have the required value):

password required pam_pwquality.so retry=3

Note: The value of "retry" should be between "1" and "3".

Check Contents

Verify the operating system uses "pwquality" to enforce the password complexity rules.

Check for the use of "pwquality" with the following command:

# cat /etc/pam.d/system-auth | grep pam_pwquality

password required pam_pwquality.so retry=3

If the command does not return an uncommented line containing the value "pam_pwquality.so", this is a finding.

If the value of "retry" is set to "0" or greater than "3", this is a finding.
