Design and implementation of integrated security engine for secure networking

Conventional security systems provide the functions like intrusion detection, intrusion prevention and VPN individually, leading to management inconvenience and high cost. To solve these problems, attention has been paid on the integrated security engine integrating and providing intrusion detection, intrusion prevention and VPN. This paper introduces a security framework that allows secure networking by mounting integrated security engine to the network nodes like router or switch. Also, this paper introduces the structure of integrated security engine for router which provides and integrates intrusion detection and intrusion prevention, and describes core functions and algorithms implemented for the functions. Finally, this paper explains the efficiency of integrated security engine by comparing security network structure based on the network node equipped with integrated security engine, and security network structure composed of conventional individual systems.
