Efficient and extensible security enforcement using dynamic data flow analysis
Current taint tracking systems suffer from high overhead and a lack of generality. In this paper, we solve both of these issues with an extensible system that is an order of magni...

A Service Dependency Modeling Framework for Policy-Based Response Enforcement
The use of dynamic access control policies for threat response adapts local response decisions to high level system constraints. However, security policies are often carefully tigh...

An Algebraic Basis for Specifying and Enforcing Access Control in Security Systems
Security services in a multi-user environment are often based on access control mechanisms. Static of an access control policy can be formalised using abstract algebraic models. W...
