What Every Security Professional Needs to Know About WiFi 6

Explore the critical aspects of WiFi 6 and its security implications in this 53-minute conference talk from the RSA Conference. Gain insights from Dr. Avril Salter, a Wireless Strategic Technologist and Architect, as she compares WiFi 6 with existing WiFi solutions and emerging 5G standards. Delve into the key technical differences between WiFi 6 and its predecessors, and examine the enhancements of WPA3 security over WPA2. Learn about the increasing complexity of eavesdropping on user data transmitted over the air and evaluate the sufficiency of WPA3 in supporting IoT devices. Understand the advancements in multiple simultaneous users, smaller subcarriers, resource allocation, modulation techniques, and operational efficiency. Apply this knowledge to better prepare for the deployment of next-generation WiFi products and address recent wireless attacks and vulnerabilities.
