There are various Apache modules that implement some kind of rate limiting. Eg. mod_security or mod_qos and services like stopforumspam and other blacklists to detect malicious requests.
My question: Is there some software that lets me comfortably manage white- and blacklists, include data from outside sources together with a nice GUI?
For example I want to easily see the top requesting hosts and whitelist or blacklist them or their networks. I want to be able to define IP blocks that are potentially less trusted than others and mark certain patterns in the request strings.
Is there a preferably open source, but not necessarily free, product that facilitates these tasks and integrates with Apache?
