Seraphim: dynamic interoperable security architecture for active networks

Security is an important concern in the active networking paradigm because a breach in security can quickly compromise many systems in the network. The paper describes an extensible, reconfigurable security architecture that is flexible and accommodates a wide variety of security policies and mechanisms. It provides applications and users with the ability to create and enforce highly customized and situational policies dynamically, and is well-suited to the security issues in active networks. R.H. Campbell and M.D. Mickunas (1998) implement this architecture and allow the creation of dynamic security policies. Innovative applications use these policies in an exploration of the nature and scope of “dynamic security”. The implementation facilitates research of interoperability and portability security issues. Based on the experience from this effort, we are investigating a unified model for security mechanisms that preserves security guarantees across domains
