Hardening TLS for WLAN 802.1X Authentication
This post outlines some configuration changes which can enhance the security of 802.1X EAP methods PEAP and EAP-TTLS, which use a temporary layer 2 TLS tunnel to protect a less secure inner authentication method. While EAP-TLS doesn’t create a full TLS tunnel, it does use a TLS handshake to provide keying material for the four-way handshake. It needs strong TLSContinue reading “Hardening TLS for WLAN 802.1X Authentication”
