Simulation Model Design of a Security System Based on a Policy-Based Framework

Abstract

The management of network infrastructure is difficult and complex with the growth of the Internet. In an era of increasing technical complexity, it is becoming difficult to find trained personnel who can manage the new features introduced into the various servers, routers, and security systems. This article describes the modeling and simulation of a security system based on a policy-based framework that has some merits. Each component is implemented in a hybrid design using modeling concepts from discrete event system specification (DEVS) formalism and problem-solving concepts from the blackboard architecture of artificial intelligence. The authors propose that the intrusion detection system detects intrusions by using the blackboard and reports this information to the policy-based framework for automatic management. The policy server informs the firewall about this situation to prevent damage to the network.
