DDoS (Distributed Denial of Service Attack)

Distributed denial-of-service(DDoS) attack is a combination of compromised systems attacking a single computing system causing a denial of service. The incoming traffic to the targeted system eventually forces it to shutdown making it incapable of providing service to legitimate users.
Generally there are two types of DDoS attacks.

• Network centric attack: Service is overloaded by consuming the bandwidth.
• Application-layer attack: A service or database is overloaded with application calls. The excessiveness of the traffic to the target system causes a denial of service.
