Port Knocking is an important concept to secure services provided by the servers. By a predefined port knocking sequence server identify whether the request is a legitimate request for a service. In this paper, the authors present an analyzing the network security concept of Port Knocking and assesses their suitability as firewall authentication mechanisms for opening network ports or performing certain actions on servers. This paper are developing and evaluating the performance of a new proposed Modified Hybrid Port Knocking (MHPK) technique with proposed encryption/decryption technique. Prime concerned of the proposed work is to prevent different - different types of port attack and fulfill the entire security requirement for network.
