"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

mod_security is leading open-source web application firewall. To use its fill potential, one must have good knowledge about HTTP protocol and web server internals. It has got many advanced features and  it can scan entire request's headers/body/response and response etc. You can write fairly advanced rules with this module. However,it has considerable impact on performance depending on rules applied,hardware capacity and incoming traffic. For medium to large deployments, it is suggested to have a separate installation of mod_security and redirect valid request to server behind it. Again; be aware this could be a bit expensive on your processor, depending on how many rules you enable, but it does have real-time Denial of Service, flooding, and slow connection protection.
