You may be able to be effective in enforcing this on people in your own
organization. However, you are likely to be disappointed when you look at
your Internet feed. It's hard to see what options you have, other than
hardening your site. The simple fact of your presence on the `net is an
implicit invitation to receive unsolicited traffic. While that includes
things like this list, it also includes less interesting stuff like spam
and probes.
This is why you want things like firewalls and intrusion detection.
ObDisclaimer: I make a scanning product. Our customers think it's a useful
tool to help them administer their networks. We go to rather a lot of
trouble to make our scanner really, really noisy, so you'll know if
someone's scanning you (if you're paying attention).
