Apache mod_evasive (also formally known as Mod_dosevasive) helps to prevent HTTP DoS (DDoS) attacks or server brute force attacks. The module works it's magic by blocking access to your server from connections by the perpetrating single IP address that exceeded more than 50 concurrent connections to Apache or loading the same page more then a few times per second.

Detection is performed by creating an internal dynamic hash table of IP Addresses and URIs, and denying any single IP address from any of the following:

1. Requesting the same page more than a few times per second
2. Making more than 50 concurrent requests on the same child per second
3. Making any requests while temporarily blacklisted (on a blocking list)

The module will help protect against people sending too many requests to the webserver in an attempt to flood it. If it detects too many connections the offending ip will be blocked from the accessing apache for This is especially useful when the server is continuously getting attacked. With this default configuration it will block the offending ip for 10 minutes. If it continues to try and flood mod_evasive will automatically add more time to this.
