TOSS 5 must ensure the password complexity module is enabled in the password-auth file.

Enabling PAM password complexity permits enforcement of strong passwords and consequently makes the system less prone to dictionary attacks.

Verify TOSS 5 uses "pwquality" to enforce the password complexity rules in the "password-auth" file using the following command:

$ cat /etc/pam.d/password-auth | grep pam_pwquality

password required pam_pwquality.so

If the command does not return a line containing the value "pam_pwquality.so", or the line is commented out, this is a finding.

Configure TOSS 5 to use "pwquality" to enforce password complexity rules.

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

password required pam_pwquality.so
