1.A RADIUS server is only required if out-of-band NAC is implemented with the NAC Gateway, and 802.1X or web-based authentication is deployed on the network.

2.NetSight Policy Manager is required for inline NAC deployments. NetSight Policy Manager is suggested if Enterasys policy-capable switches are deployed on the network and utilized as the traffic enforcement or authorization point for connecting devices. Policy Manager allows the centralized definition and deployment of policies to Enterasys switches for the consistency and ease of management of the authorization levels for connecting end-systems.

3.NetSight Inventory Manager is suggested if Enterasys switches are deployed on the network for ease of firmware and configuration management across the enterprise.

The NAC Appliance

The NAC appliance is a core component of the Enterasys NAC solution and is required for all NAC deployment models. It provides the ability to detect, authenticate, and effect the authorization of end devices attempting to connect to the network. It also integrates with or connects to assessment services to determine the security posture of end‐systems connecting to the network. Once authentication and assessment are complete, the NAC appliance effects the authorization of devices on the network by allocating the appropriate network resources to the end‐system based on authentication and/or assessment results.

If authentication fails and/or the assessment results indicate a noncompliant end‐system, the NAC appliance can deny the end‐system access to the network, quarantine the end‐system with a highly restrictive set of network resources, or permit network access, depending on the appliance’s configuration.

The NAC appliance also provides the remediation functionality by means of a Remediation Web Server that runs on the appliance. Remediation informs end users when their end‐systems have been quarantined due to network security policy non‐compliance, and allows end users to safely remediate their end‐systems without assistance from IT operations.
