摘要: We focus in this paper on the problem of configuring and managing network security devices, such as Firewalls, Virtual Private Network (VPN) tunnels, Intrusion Detection Systems (IDSs). Our proposal is following. First, we formally specify requirements a given system by using an expressive access control model. As result, obtain abstract policy, which free ambiguities, redundancies or unnecessary details. Second, deploy policy through set automatic compilations into devices system. This proposed deployment process not only simplifies administrator's job, but also guarantees resulting configuration anomalies and/or inconsistencies.
