A Denial of Service (DoS) or Distributed Denial of Service is a very ancient type of cyber threat which is still prevalent and is increasing day by day. Within DoS, numerous requests are generated and sent to the sophisticated server beyond its handling capacity which results into denial or suspension of services and sometimes into crashing of the server.
While in the Distributed Denial of Service, more than one server raises the DoS attacks targeting server by sending unlimited bandwidths of request so that no new requests are accepted further. Main targets of such attacks usually are: large organizations, banks, payment gateways and root nameservers. Malware named “MyDoom” is considered to be responsible for launching the DDoS attacks.
