Network Access Control

We focus our investigation on adding context to empower fine-grained network access control for elaborate attacks. To this end, we examine the introduction of software designed networking (SDN) and the new opportunities it offers for network defense systems. SDN offers flexibility, transparency, and distributed control to enable novel security mechanisms not feasible in traditional networks. Our work examines if network-based access control can evolve to prevent elaborate attacks and application behaviors under varying context. To this end, we examine the various design and telemetry decisions for IoT devices as they offer an emerging and complex threat.

Bluetooth Security

Bluetooth, a protocol designed to replace peripheral cables, has grown steadily and includes a variety of applications. In near ubiquity now, the Bluetooth protocol operates on a wide variety of mobile and wireless devices. Several attacks exist that successfully target and exploit Bluetooth enabled devices. Our research implements a network intrusion detection system for discovering malicious Bluetooth traffic.

Information Security Education


The combination of competitive security exercises and hands-on learning represents a powerful approach for teaching information system security. Although creating and maintaining such a course can be difficult, the benefits to learning are worthwhile. Our research explores countering enrollment decline via a curriculum that carefully exposes students to computer security as a means of teaching core computer science concepts, including algorithms, networks, compilers, programming languages, and operating systems.
