Fix Recommendation

If an account is configured for password authentication but does not have an assigned password, it may be possible to log on to the account without authentication.

Remove any instances of the "nullok" option in "/etc/pam.d/system-auth" and "/etc/pam.d/password-auth" to prevent logons with empty passwords.

Check Contents

To verify that null passwords cannot be used, run the following command:

# grep nullok /etc/pam.d/system-auth /etc/pam.d/password-auth

If this produces any output, it may be possible to log on to accounts with empty passwords.

If null passwords can be used, this is a finding.
