Better living through mod security
We've all heard of web application level firewalls, and they're certainly not something new, with several good commercial offerings available for quite some time. Most of these products will offer some kind of web based administration and reporting facilities to allow simple and straight forward management.
On the open source end of the scale we have a project named ModSecurity, an open source intrusion detection and prevention engine for web applications. Operating as an Apache Web server module, the purpose of ModSecurity is to increase web application security, protecting web applications from known and unknown attacks.
