How do I stop the guest group (unregistered) from being able to view registered members profiles on v4?

There must be a setting somewhere?

Thanks.

I just went through this. 

In the ACP: Members>Groups>Guests

Then set the permission Can read site to off.

Oh, so all or nothing, that's versatile!

 

Thanks for your help.

Overkill.

ACP -> System -> Applications -> System -> Profiles

Click the permissions icon (the lock)

Untick 'can access module' for the Guests group.

Thanks Nathan but when you are desperate to get it all turned off because people are reading what shouldn't be open to the public that was the only one I could find. The way this is set up is not intuitive at all for me. I will check that out as well. Why aren't the settings all in one place for permissions?
