Cisco EAP-FAST (Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling) is a protocol used for wireless network authentication. It is a secure authentication method that allows users to authenticate to a wireless network without exposing their credentials in clear text.
EAP-FAST uses a server-side Public Key Infrastructure (PKI) to establish a secure tunnel between the client and the authentication server, and then securely authenticates the client using a Protected Access Credential (PAC) or a One-Time Password (OTP). This method provides secure and efficient authentication, making it a popular choice for enterprises and organizations that require strong wireless security.
The Cisco EAP-FAST module is a software component that enables EAP-FAST authentication on Cisco networking equipment, including routers, switches, and access points. The module provides the necessary functionality to support EAP-FAST authentication, such as client and server authentication, PAC provisioning, and secure tunnelling.
