Identify Inline or Out-of-band NAC Deployment

Remote Access VPN

In many enterprise environments, a VPN concentrator located at the main site connects to the Internet to provide VPN access to remote users. In this scenario, there is no concept of intelligent and non‐intelligent edge switches because the entry point to the main site is the VPN concentrator. In this scenario, the NAC Controller must be used to implement NAC for remote access VPN end‐ systems, and it should be positioned behind the VPN concentrator that provides remote access VPN. Again, reverse proxy VPN or many‐to‐one NAT implemented on a downstream device from the NAC Controller is not supported in the Enterasys NAC solution.

Identify Inline or Out-of-band NAC Deployment

Based on the NAC deployment model you selected, and the results of your network infrastructure evaluation, you must identify whether out‐of‐band NAC or inline NAC will be deployed in the different areas of your network. With the decision to implement out‐of‐band NAC with the NAC Gateway, and/or inline NAC with the NAC Controller, the next design step is to determine your specific enterprise requirements for the selected NAC solution, and identify the number of NAC appliances, and their location and configuration on the network.

Summary

The first step when planning your NAC deployment, is to identify the NAC deployment model, or a phased implementation of multiple deployment models, that meets your NAC business objectives. Once you have selected a deployment model, you can use the four following steps to evaluate your current network infrastructure and determine your NAC component requirements.

1.Identify the “intelligent edge” in your network, if it exists. This information will be used to help you select which NAC appliance, the NAC Gateway or NAC Controller, best suits your network infrastructure.

An intelligent edge is required when the NAC Gateway is utilized for implementing out‐of‐ band NAC. The NAC Gateway appliance leverages the intelligent edge of the network to implement the authentication and authorization of connecting end‐systems.

In networks with non‐intelligent devices at the access edge, it is not necessary to replace these non‐intelligent devices to be able to implement out‐of‐band NAC with the NAC Gateway. Instead, the Enterasys Matrix N‐series switch can be positioned upstream from non‐intelligent devices (such as in the distribution layer) to implement the authentication and authorization functions for downstream connected devices.

If the network does not have an intelligent edge, then the NAC Controller must be deployed in order to provide the authentication and authorization capabilities required for implementing network access control.

2.Evaluate the network authentication method currently being used, and how the deployment of Enterasys NAC will affect it. (This step is not required if you have determined that the network does not have an intelligent edge and the inline NAC Controller will be deployed.)

If authentication is not configured on the network, out‐of‐band NAC can be deployed with minimal configuration by implementing MAC authentication on the intelligent edge of the network (if the edge switches support MAC authentication).

If authentication is currently deployed on the network with 802.1X, web‐based, and/or MAC authentication, out‐of‐band NAC is configured to proxy RADIUS authentication requests received from the switches at the intelligent edge of the network to the backend RADIUS
