Security is of critical importance to the success of active networking. In addition, we argue that active security based on active networking principles can offer a wide range of opportunities to build better security systems. This paper describes an extensible, reconfigurable security architecture based on active networking that is flexible and accommodates a wide variety of security policies and mechanisms. It provides users the ability to dynamically create and enforce highly customized and situational policies for their applications. Active security also permits security systems to react to intrusion and can aid the application of the "need-to-know" security principle to network software and application security. We describe a prototype implementation of an active security architecture that allows us to create dynamic security policies. Using these policies we show innovative applications that let us explore and discover the nature and scope of ``dynamic security''''. The implementation forms the basis for exploring complex issues including interoperability, mobility, and portability.
