PIDS: A Packet Based Approach to Network Intrusion Detection and Prevention

Computer networks are one of those unique gifts of modern science which enriched human life with the blessing of global connectivity. But as the network advanced, intrusions and misuses followed. Consequently, network security has come into issue. Now-a-days intrusion detection systems have become a standard component in security infrastructures. Intrusions typically start with intruders infiltrating a network through a vulnerable host and after that approaching for further malicious attacks. The techniques used for intrusion detection have their particular limitations. Any of the intrusion detection systems proposed so far is not completely flawless. And practically all of them require some kind of termination in network connections. So, the quest for betterment continues. In this progression, here we present PIDS: a complete intrusion detection system which reduces most of the problems contained by the previous systems and it doesnpsilat need to terminate any network connections to detect the intruder. This system generates quick responses against intrusions and stops the intruder to proceed for further attacks.
