Enterprise Wi-Fi: EAP and RADIUS
Configure WPA2-Enterprise with EAP-TLS, understand certificate-based auth, and secure RADIUS servers.
Why Enterprise Wi-Fi?
WPA2-Personal uses a shared password — everyone knows the same secret. WPA2/WPA3-Enterprise uses 802.1X with individual credentials or certificates, enabling per-user authentication, revocation, and audit logs.
802.1X Framework
802.1X defines three roles: Supplicant (client device), Authenticator (AP/switch), and Authentication Server (RADIUS). The AP proxies credentials to RADIUS without knowing them.
# 802.1X flow:
# 1. Client connects to AP
# 2. AP blocks all traffic (uncontrolled port)
# 3. AP proxies EAP to RADIUS server
# 4. RADIUS authenticates client
# 5. RADIUS sends accept + session keys
# 6. AP opens controlled port for clientAll lessons in this course
