Design Planning

This chapter describes the steps you should take as you begin planning your NAC deployment. The first step is to identify the deployment model that best meets your business objectives. Then, the current network infrastructure must be evaluated in order to determine NAC component requirements. Based on this evaluation, you will be able to decide whether to deploy inline or out‐ of‐band network access control.

Identify the NAC Deployment Model

When planning your NAC deployment, the first step is to identify the NAC deployment model, or a phased implementation of multiple deployment models, that meets your NAC business objectives. The four deployment models are summarized below. For more in depth information on each model, see Chapter 2, NAC Deployment Models.

•Model #1: End‐System Detection and Tracking

Enterasys NAC detects devices as they connect to the network, identifying the location, MAC address, IP address, and username of the person using the end‐system. This information is maintained over time for each device on the network, yielding complete historical information about a device as it interacts with the network.

•Model #2: End‐System Authorization

Enterasys NAC detects, authenticates, and authorizes connecting end‐systems, to control access to network resources based on location as well as user and end‐system identity.

•Model #3: End‐System Authorization with Assessment

Enterasys NAC is deployed with end‐system assessment and authorization (but without remediation), to control access to network resources based on the security posture of a connecting end‐system. Compliant end‐systems are permitted onto the network, while end‐ systems that fail assessment can be dynamically quarantined with restrictive network access.

•Model #4: End‐System Authorization with Assessment and Remediation

In addition to end‐system assessment and authorization, Enterasys NAC is deployed with remediation to dynamically inform quarantined end‐systems of security compliance violations. Using web‐based notification, assisted remediation allows end users that have
