Matthew Burnside: Integrated Enterprise Security Mgmt

6:30 pm, Soho Apple Store at 103 Prince Street

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.
