Historically, DDoS attacks are associated with hacker and hacktivist groups and often considered to be a work of professional cyber crooks. Please read more on how Anti DDoS Guardian stops layer 7 and application layer DDoS attacks.DDoS stands for Distributed Denial of Service, a malicious attempt to make a server or a network resource unavailable to legitimate users, by overloading it with massive amounts of fake traffic. If a client tries to access a server with too many TCP connections, the client will be blocked.

How to prevent application layer (L7) DDoS attacks?Īnti DDoS Guardian defeats application layer (L7) DDoS attacks by limiting the number of concurrent TCP connections per client.

Application layer DDoS attacks can also be referred to as layer 7 (L7) attacks. For these reasons, application-layer DDoS attacks are efficient, low-cost, and difficult to detect. An attacker's goal can be achieved at low volume with a small number of client computers. Therefore, it is impossible to serve real customers. It's like too many fake customers come to the restaurant without ordering. Since there is a limit to the number of concurrent TCP connections for each Internet server, a client can send many TCP connection requests to overcome the server's TCP connection threshold without a single connection request completing. The idea is to consume the server's TCP/IP resources at little cost by having too many TCP connections.

What is an application layer (L7) DDoS attack?Īpplication-layer DDoS attacks are initiated by multiple clients against the server's TCP/IP application layer.

On top of that, Anti DDoS software often saves money.

With Anti DDoS software, you can easily manage network traffic and control TCP connections. However, when DDoS attacks involve the application layer, Anti DDoS software does a better job. CDNs are very effective against large-scale attacks targeting the physical layer. This is because Internet servers need to provide additional protection on top of CDN DDoS protection.

Since it is software, it is flexible and configurable. Anti DDoS software works on different network layers to detect illegal network traffic and mitigate attacks. Find more on What is a DDoS attack?Īnti DDoS software is a software component installed on Internet servers to prevent DDoS attacks. A DDoS attack means that a large number of illegal computers are accessing internet servers at the same time, and the huge flood of incoming traffic makes the servers unable to respond to legitimate users.
