Types of attacks -Distributed Denial of Service (DDoS) attack

A Distributed Denial of Service (DDoS) attack is a type of Denial of Service (DoS). In Distributed Denial of Service (DDoS) attack multiple systems flood the bandwidth or overload the resources of a targeted server.

In Distributed Denial of Service (DDoS), an intruder compromise one computer and make it Distributed Denial of Service (DDoS) master. Using this Distributed Denial of Service (DDoS) master, the intruder identifies and communicates with other systems that can be compromised. Then the intruder installs Distributed Denial of Service (DDoS) tools on all compromised systems. With a single command, the intruder instructs the compromised computers to launch flood attacks against the target server. Here thousands of compromised computers are flooding or overloading the resources of the target server preventing the legitimate users from accessing the services offered by the server.
