Integrated Enterprise Security Management
Security policies are a key component in protecting enterprise networks. But, while there are many diverse defensive options available, current models and mechanisms for mechanically-enforced security policies are limited to traditional admission-based access control. Defensive capabilities include among others logging, firewalls, honeypots, rollback/recovery, and intrusion detection systems, while policy enforcement is essentially limited to one-off access control. Furthermore, access-control mechanisms operate independently on each service, which can (and often does) lead to inconsistent or incorrect application of the intended system-wide policy. We propose a new scheme for global security policies. Every policy decision is made with near-global knowledge, and re-evaluated as global knowledge changes. Using a variety of actuators, we make the full array of defensive capabilities available to the global policy. Our goal is a coherent, enterprise-wide response to any network threat.
