802.1X Authenticated Wireless Access

June 14th, 2012 Comments off

Windows Server provides features that you can use to deploy IEEE 802.1X authenticated wireless service for wireless network clients. In combination with the 802.1X-capable wireless access points APs and other Windows Server services that you deploy on your network, you can use these Windows Server features to control who can access your network.

You can also use features in Windows Server to define the wireless network adapter connectivity and security settings that your wireless clients use for connection attempts. For example, Network Policy Server NPS allows you to create and enforce network access policies for authentication, authorization, and client health. The Wireless Network (IEEE 802.11) Policies in Windows Server Group Policy GPO enable you to configure your network client computers with the security and connectivity settings that they must use to connect to your network.

This checklist provides the tasks required to deploy 802.1X wireless access points with Network Policy Server (NPS).

Task Reference
Install and configure 802.1X wireless access points on your network. RADIUS Server for 802.1X Wireless or Wired Connections and your hardware documentation
Determine the authentication method you want to use. RADIUS Server for 802.1X Wireless or Wired ConnectionsCertificate Requirements for PEAP and EAPEAP OverviewPEAP Overview; and your hardware documentation

Configure 802.1X wireless access clients by using the Group Policy Management extension, Wireless Network (IEEE 802.11) Policies. Configure 802.1X Wireless Access Clients by using Group Policy Management
Configure 802.1X wireless access points as Remote Authentication Dial-In User Service (RADIUS) clients in NPS. Add a New RADIUS Client and RADIUS Client
Create a user group in Active Directory® Domain Services (AD DS) that contains the users who are allowed to access the network through the wireless access points. Create a Group for a Network Policy
In NPS, configure one or more network policies for 802.1X wireless access. Add a Network PolicyCreate policies for 802.1X Wired or Wireless with a Wizard; and Network Policies

EAP-TTLS by Microsoft noticed on Windows 8

It seems that EAP-TTLS is getting supported by Microsoft on the next version of Windows. Using the 802.1x Policies in the Developer Preview version of Windows 8 Build 8102, you can configure EAP-TTLS as an authentication method for both Wireless and Wired IEEE 802.3 & 802.11 Policies.
