The operating system must not allow logins for users with blank passwords.

If the password field is blank and the system does not enforce a policy that passwords are required, it could allow login without proper authentication of a user.

Determine if the system is enforcing a policy that passwords are required.

# grep ^PASSREQ /etc/default/login

If the command does not return:

PASSREQ=YES

this is a finding.

The root role is required.

Modify the /etc/default/login file.

# pfedit /etc/default/login

Insert the line:

PASSREQ=YES
