액티브 네트워크는 패킷이 목적지에 도착하기 전에 거치게되는 중간노트에서 새로운 정책이나 코드를 추가하여 프로그램을 실행시킬 수 있는 소프트웨어 기반 차세대 네트워크이다. 이러한 액티브 네트워크 환경에서는 다이나믹하게 패킷을 처리할 수 있지만 중간 노드에서 패킷을 처리하기 위해서는 그 노드의 자원을 사용해야 한다. 따라서 액티브 네트워크에서는 기존의 네트워크와는 달리 중간노트의 자원에 접근함으로써 발생하게 되는 네트워크 보안상의 문제점들을 고려하지 않으면 안 된다. 본 논문에서는 액티브 네트워크 환경에서 액티브 노드의 자원에 접근 시 발생되는 보안상의 문제점들을 해결하기 위한 보안 강화 엔진을 제안하고, 보안 강화 엔진 내에 보안, 인증, 권한부여 모듈을 두어 액티브 네트워크 환경에 노출되어있는 악의적인 위협 요소들로부터 보호하고자 한다.
