Abstract

The rapid growth and increasing pervasiveness of wireless networks raises serious security concerns. Client devices will migrate between numerous diverse wireless environments, bringing with them software vulnerabilities and possibly malicious code. Techniques are needed to protect wireless client devices and the next generation wireless infrastructure. We propose QED, a new security model for wireless networks that enables wireless environments to quarantine devices and then analyze and potentially update or "decontaminate" client nodes. The QED paradigm is presented here, as well as the design of a practical prototype.
