Security Simulation Modeling Using Contract Net Protocol

Abstract

To solve the security problems which occur in the network such as Internet, we import software products of network security elements like an intrusion detection system (IDS) and a firewall. In this paper, we have designed and constructed the general simulation environment of network security model composed of multiple IDSs and a firewall, which coordinate by contract net protocol (CNP) for the effective detection of the intrusion. The CNP, the methodology for efficient integration of computer systems on heterogeneous environment such as distributed systems, is essentially a collection of agents which cooperate to resolve a problem. In the network security model, each model of simulation environment is hierarchically designed by discrete event system specification (DEVS) formalism. The purpose of this simulation is to evaluate the characteristics and performance of CNP architecture for the speeding up the inference cycle phases of the intrusion detection expert system.
