What, Why and How

  1. What is a DDoS attack?
  2. A DDoS attack means numerous illegal computers access an Internet server at the same time and the huge incoming traffic flooding makes the server unable to response legal users. Find more on What is a DDoS attack?

  3. What is Anti DDoS software?
  4. Anti DDoS software is software components installed on Internet servers to stop DDoS attacks. Anti DDoS software works on different network layers to detect illegal network traffic and mitigate attacks. Since it is software, it is flexible and more configurable. Please click here to learn more about Anti DDoS software.

  5. Why use Anti DDoS software?
  6. It is because Internet servers need additional shield on top of CDN DDoS protection. CDNs are effective at huge attacks aimed at physical layer. However, when DDoS attacks come to application layer, Anti DDoS software does better job. Through Anti DDoS software, network flows can be easily managed and TCP connections are under controlled. In addition to that, Anti DDoS software is usually cost saving.

  7. What is an application layer (L7) DDoS attack?
  8. An application layer DDoS attack is launched by multiple clients targeting a server's TCP/IP application layer. The idea is to consume servers' TCP/IP resources with excessive TCP connections at little cost. Since for each Internet server there is a number limit for concurrent TCP connections, clients can send many TCP connection requests to overcome a server's TCP connection threshold with none ever being completed. It is like too many faked customers come to a restaurant without ordering food. They just sit there and wait. Therefore, no real customers can be served. Attackers' goal can be achieved with low volume by only a small number of client computers. For these reasons, application layer DDoS attack is efficient, cost saving and hard to be detected. The application layer DDoS attacks can also be called layer 7 (L7) attacks.

  9. How to prevent application layer (L7) DDoS attacks?
  10. Anti DDoS Guardian defeats application layer (L7) DDoS attacks by limiting each client's TCP concurrent connection number. If one client tries to access a server with excessive TCP connections, the client will be blocked. Please read more on how Anti DDoS Guardian stops Slow HTTP Get&Post Attacks.

"I must really compliment you on your work. Anti ddos guardian is amazing......It works better than anything we've used......It's too cheap......People will offer a lot more for this kind of protection......Especially once they know how well it works......There is no other software that I've seen that actually worked well......"---Daniel Bowen
"anti ddos guardian blocks ddos attacks generally......so it does the required job......before i found your program , my friend paid 300$ to ......but you know , their programs made setting up the program hard for user i think......" ---Muhammod Yunus
