The desire for flexible networking services has given rise to the concept of active networks. Active networks provide a general framework for designing and implementing network-embedded services, typically by means of a programmable network infrastructure. A programmable network infrastructure creates significant new challenges for securing the network infrastructure. This paper begins with an overview of active networking. It then moves to security issues, beginning with a threat model for active networking, moving through an enumeration of the challenges for system designers, and ending with a survey of approaches for meeting those challenges. The Secure Active Networking Environment SANE realizes many of these approaches an implementation exists and provides acceptable performance for even the most aggressive active networking proposals such as active packets sometimes called capsules.We close the paper with a discussion of open problems and an attempt to prioritize them.
