The debate that people often have is that you can only protect what you know about and therefore can only protect against known threats. While on the surface there is some general logic to this thinking, with proper host hardening we believe that you can also protect against the unknown threats. Let’s imagine that there is a system that is a Web server and also happens to have an email server running on TCP port 25. There is no reason that the Web server should be running email, so after careful analysis the service is removed and the port is closed. Based on the actions that were performed was the host properly protected against the zero day attack—absolutely. Now in hardening the box, we did not know the specific threat we were defending against but we were still able to defend and stop a zero day attack from being successful. While patching is important, the best way to secure a service is not to patch, it is to remove a service from a system.

We call this approach bottom up because we based all our investigations and analyses on data gathered from users in the existing work practice, avoiding other insights and inputs. We involved users to ensure that what we are doing is consistent with the way they get work done. Top-down approaches emphasize planning and a complete understanding of the system.
