This control allows for continued management of access policies and also enables event logging for accounting purposes. Not only does NPS offer configurable policies for network access, but it also ensures non-Microsoft devices can connect once authenticated.īy placing users and client devices in groups or automating classification, administrators can control the types of clients and permissions available to network users. Network Policy Server is the solution for Windows network administrators using RADIUS capabilities. Read more : What is Server Management? What Is the Purpose of NPS? The NAS works with the RADIUS server, relying on its AAA capabilities to authenticate the user and respond with permission for the proper configuration. For example, you can configure one NPS server to act as a NAP policy server using one or more enforcement methods, while also configuring the same NPS server as a RADIUS server for dial-up connections and as a RADIUS proxy to forward some connection requests to members of a remote RADIUS server group for authentication and authorization in. Within communication protocols for networks, like user datagram protocol (UDP) or transmission control protocol (TCP), RADIUS servers communicate with network access servers.Ī client device makes a connection request to the network access server (NAS). Clients for the RADIUS server represent network access points users make requests to RADIUS clients that pass along the request to the RADIUS server for authentication.

RADIUS servers can run on Windows or Unix servers and, most importantly, allow administrators to control who can connect to the network.

While dial-up has lost its luster in enterprise use, RADIUS servers remain a convenient way to offload authentication from access points. RADIUS stands for Remote Authentication Dial-In User Service and was initially a client-server protocol for dial-up connections. NPS Best Practices What Is the RADIUS Protocol?.
