Is there anything against DDoS to protect Apache HTTPD web server?

Solution Verified - Updated -


  • DDoS Attacks could be SYN flood, UDP flood, ICMP flood and SMURF attacks. DoS attacks now target the application service itself, to deny service in a way that evades current protection mechanisms. Attackers use legitimate application requests to overload the web server, HTTP Layer 7-type attack is more difficult to stop because it is requires to distinguish between real and malicious HTTP request, while all carried by apparently legitimate traffic.
  • Under Linux, multiple module exist such as mod_qos, mod_security, mod_evasive etc. but which one should take to avoid DDOS attack ?
