With the majority of hacker attacks coming at the web application level these days, a web application firewall is needed to thwart these attacks before they reach the web applications. Modsecurity is an Open Source web application firewall that amongst other things, allows for full HTTP transaction logging which facilitates the logging of complete requests and responses. These logging functions can be fine tuned by webmasters who can choose exactly what to log and record.
