Traffic gatekeeping, typically implemented using firewalls, is an essential functionality in today's networked computing systems such as desktop PCs. Traffic gatekeeping provides protection against a variety of over-the-network security attacks and can also be used to implement various communication resource management policies. With the development of technologies such as IPv6 and 6LoWPAN that pave the way for Internet-connected embedded systems and sensor networks, traffic gatekeeping will soon become a must-have for these systems as well. Towards this, we present Aegis, a lightweight, rule-based traffic gatekeeping framework for sensor networks. We present an overview of the Aegis architecture, its implementation, and two usage scenarios.
