As the Network Security Architect with the Office of the CTO at Enterasys Networks, Dick Bussiere is responsible for network security, including Virtual Private Networks (VPNs), firewalls, PKI and Layer 2, 3, and 4 security schemes, such as 802.1X user authentication. Bussiere chairs the Technical Council's Network Security Architecture Project Team, which defines the Enterasys strategy for overall security architecture, user authentication, VPNs, Intrusion Detection Systems, firewalls and device security and management. He is a member of both the IEEE 802.1 and the IETF.

Bussiere joined the company in 1994 as an engineer for the SecureFast switching group. In this role, he developed the architecture of a next-generation VPN gateway device and Layer 2, 3, and 4 switching devices, as well as the low-level firmware implementation of first-generation hardware Layer 2 switching platforms.

Prior to joining Cabletron and Enterasys, Bussiere was a firmware engineer at Lockheed Martin where he designed and implemented the hardware and firmware for the communications subsystem of a large, multiprocessor surveillance platform and a high-performance signal processing system, as well as the communications subsystem in the F22-Raptor Electronic Warfare (EW) system.
