Denial of Service (DoS)/Distributed Denial of service is a type of cyber offensive attack where resources like network bandwidth, memory and computational power are attacked by rogue elements. In order to safeguard the server against such attacks a new type approach was proposed by Zhao [1]. This approach is called software puzzle approach. The software puzzle approach basically runs on CPU. In this paper we studied and implemented this approach. This approach is found to be effective as it creates computationally difficult task for the malicious attackers so that they cannot overwhelm the server.
