A Modified Hybrid Port Knocking Technique for Host Authentication A Review

Abstract

The main objective is to develop and assess the performance of a replacement PK technique, which may avert all kinds of port attacks and meets all network security necessities. Port knock is a crucial conception to secure services provided by the servers. By a predefined port knock sequence server establish whether or not the request could be a legitimate request for a service. The new technique uti lizes three acknowledge ideas, these are: port - knocking (PK), steganography, and mutual authentication, therefore, it mentioned because the hybrid port - knocking (HPK) technique. It are often used for host authentication to form native services invisible from port scanning, giv e an additional layer of security. During this paper presents analyzing the network sec urity concept of Port knock and assess their quality as firewall authentication mechanisms for gap network ports or activity bound actions on servers. This paper is developing and evaluating the performance of a replacement proposed modified hybrid port kn ock (MHPK) technique with proposed encryption/decryption technique. The planned technique is to stop completely different - different kinds of port attack and fulfill the complete security demand for network. Planned technique is that the combination of 4 i deas, this are port knocks (PK), symmetric key encryption/decryption, steganography and mutual authentication. Primarily it the improved modification of hybrid port knocking therefore; it observed because the modified hybrid port - knocking (MHPK) technique.
