Web Application Firewall Use Cases Update

My list of web application firewall use cases continues to involve. I've decided to shuffle things somewhat:

  1. I am going to remove the "Network building blocks" use case because that is really a feature of reverse proxies. If a WAF happens to be implemented on top of a reverse proxy that it will also inherit all of its benefits (and downsides, I should mention). In retrospective, I thought the two (reverse proxies and WAFs) should really stay separate.
  2. I am going to add "Learning" as a new use case. As I was looking at the previous list of use cases it stroke me that I was failing to convey the ability of web application firewalls to understand what is going on, and this is what learning does.

Note: This post is part of the Web Application Firewall Concepts series.
