If you don’t know enough to protect a Domino server exposed on the web, you shouldn’t expose it at all. You need to study up on all the security aspects of Domino before opening up your server to the world.
I know that you are correct about this and I am not comfortable with the situation that I have been thrust into here at work. Suffice it to say that I do need to get up to speed as quickly as possilbe on these security issues.
