what is protected extensible authentication protocol
What is PEAP? PEAP (Protected Extensible Authentication Protocol) is a version of EAP, the authentication protocol used in wireless networks and Point-to-Point connections. PEAP is designed to provide more secure authentication for 802.11 WLANs (wireless local area networks) that support 802.1X port access control.urrently in draft status, the protocol is gaining support and is expected to displace Cisco's proprietary Lightweight Extensible Authentication Protocol (LEAP). PEAP addresses the shortcomings of 802.11 security, shared key authentication being chief among these.
