Wireless Security WPA2, WPA3, and Enterprise Authentication - Network+ N10-009

Wireless security for CompTIA Network+ N10-009 objective 2.4. This lesson walks through WPA2, WPA3, and enterprise authentication from the ground up, so you understand what the exam is really asking and how these controls show up in the field.

You will learn why WEP and original WPA were deprecated, how WPA2 Personal combines a pre-shared key with AES-CCMP, and what actually happens during the four-way handshake. We then move into WPA2 Enterprise, covering IEEE 802.1X, the supplicant, authenticator, and authentication server roles, and how RADIUS carries credentials on UDP ports 1812 and 1813.

From there we cover WPA3, including Simultaneous Authentication of Equals (SAE), forward secrecy, and why offline dictionary attacks stop working against captured handshakes. We finish with EAP method trade-offs, comparing EAP-TLS, PEAP, and EAP-TTLS, plus best practices for guest SSIDs and captive portals.

By the end, you will be able to pick the right wireless security mode for a given network, explain the 4-way handshake, and match each EAP method to its use case.
