Designing Access Controls

Add ProCurve IDM

IDM is also required for managing a NAC 800 that enforces endpoint integrity with 802.1X quarantining. The NAC 800 checks user credentials and tests endpoints’ integrity. IDM manages the policies for assigning endpoints to VLANs based on their integrity.

Design Parameters for a Network with IDM

If you choose to use IDM, several design parameters will apply to your network:

■You must purchase and install the current versions of ProCurve Manager Plus (PCM+) and IDM.

The minimum required version of IDM is version 2.2 auto-update 2. IDM has a server component and an agent component. The server component is a plug-in to the PCM+ network management software. PCM+ and the IDM Server have the same operating system requirements: Windows Server 2000 or Windows Server 2003.

■You must install the IDM agent components on your RADIUS servers.

■

■

■

The agent component resides on the RADIUS server. These RADIUS servers support the agent:

•Windows Server 2003 version of Microsoft IAS

•Juniper Networks Steel-Belted RADIUS server

•NAC 800 (included on the device at the factory defaults)

The RADIUS server integrated on the Wireless Edge Services Module does not support the IDM agent; you must proxy requests to one of the servers listed above.

PCM+ and the IDM server can run on the same hardware as the RADIUS server (if you are using a software-based server), or they can run on a standalone server.

There can be only one PCM+ server (and IDM server) on the network. The IDM server can upload copies of the IDM agent to each of the RADIUS servers on the network.

IDM can operate with any authentication method: MAC-Auth, Web-Auth, or 802.1X (or a combination of these). Requirements for client software, such as supplicants, are determined by the authentication method.

(Because IDM interacts with the RADIUS server, it poses no requirements for the client systems.)
