Are there ways to integrate a DDoS protection system in Apache?
To integrate a DDoS protection system in Apache, one approach is to use mod_evasive module which is designed to provide evasive action in the event of an HTTP DDoS or DoS attack. This module allows the server to detect when an IP is making too many requests within a certain time frame and temporarily block that IP.
