Distributed Denial of Service (DDoS)

Distributed Denial-of-Service (DDoS) is a type of DoS attack in which many compromised systems are made to attack a single target, in order to swamp server resources and block legitimate users.

Normally many persons, using many bots, attack high-profile Web servers like banks or credit-card payment gateways. DDoS concerns computer networks and CPU resource management.

In a typical DDoS attack, the assailant begins by exploiting a vulnerability in one computer system and making it the DDoS master. The attack master, also known as the botmaster, identifies and infects other vulnerable systems with malware. Eventually, the assailant instructs the controlled machines to launch an attack against a specified target.
