The main goal of the proposed scheme protects the enterprise from attacking of hackers. Current protecting schemes filter the unauthorized packets based on the host address. However, host-based filtering is lack of flexibility when the users change their machines frequently. Besides, host-based filtering is vulnerable to spoofing attacks, and it can not protect the enterprise against internal intruders. In the proposed scheme, when user requests a service provided by the enterprise, the request is labeled according to the user’s group. Each service provider filters the illegal service request based on the security policy set by the group leader. The schemes not only supports dynamical configuration on security policy setting but also allows group membership dynamically change. Furthermore, the group-based filtering which is independent of the host address and can protect the enterprise from both external and internal attacks.
