SESSION – PACKET INSPECTOR MOBILE AGENT TO PREVENT ENCRYPTED COOKIES AND HTTP POST HIJACKING IN MANET

Abstract

A statistics states that public Wi-Fi hotspots are set to grow from 1.3 million in 2011 to 5.8 million by 2015. Due to increase in public free Wi-Fi access, userscount increases rapidly letting them to expose in vulnerable intrusion attacks. Accessing the social network and other confidential sites such as banking in public Wi-Fi, exposes the credential to the intruder. Man-in-the-middle attack plays a major role in accessing the user credential. Analysing the packets exposes the HTTP post information in the network. Capturing encrypted cookies by the man-in-the-middle can access the secure site and allows the intruder to be an authorized person. Mobile agent is a piece of code that migrates and performs actions in the host and is used to prevent intrusion. We propose a model to prevent intrusion in the wireless ad-hoc network using mobile agent. Session-Packet inspector is proposed to handle HTTP post hijacking and encrypted cookie usage by the intruder.
