After class on 9/16, I did a search on Application Firewall, also called Deep Packet Inspection Firewall. I found that a Web Application Firewall is an appliance server plug in or filter that applies a set of rules to an HTTP conversation. An Application Layer Firewall is a computer networking firewall operating at the application layer of a protocol stack. This firewall looks at the request/response within the HTTP/HTTPS/SOAP/XML-RPC/Web Service layers. Some of them look for attack signatures. The firewall can be either hardware or software and are installed in front of the webserver, between the server and the client.
Anyone have any experience in setting one of these up?
