traffic with specific source and destination characteristics as well as specific application identifiers (UDP/TCP ports). In addition, the Enterasys NAC solution will support an unlimited number of different quarantine policy roles, which means that the solution can support varying degrees of network usage restrictions depending upon the severity of the non‐compliance or security breach. This is different from many other NAC solutions that only offer a VLAN “parking lot” for end‐systems that need to be quarantined.

Required and Optional Components

This section summarizes the required and optional components for Model 4.

Table 2-4 Component Requirements for Authorization with Assessment and Remediation

	Authorization with

	Remediation
NAC Appliance	Required
NetSight NAC Manager	Required
NetSight Console	Required
Assessment Service	Required
RADIUS Server	Optional
NetSight Policy Manager	Optional
NetSight Inventory Manager	Optional

The NAC Gateway and NAC Controller are the NAC appliances used to implement the out‐of‐ band and inline network access control functionality on the network.

NetSight NAC Manager is the software application used to centrally manage the NAC appliances deployed on the network.

NetSight Console is the software application used to monitor the health and status of infrastructure devices in the network, including switches, routers, and Enterasys NAC appliances (NAC Gateways and NAC Controllers).

Assessment functionality is required because in this deployment model, connecting end‐systems are being assessed for security posture compliance.

A RADIUS server is only required if out‐of‐band network access control via the NAC Gateway is implemented with web‐based and/or 802.1X authentication.

NetSight Policy Manager is required for all inline NAC deployments, and recommended for out‐ of‐band NAC deployments that utilize Enterasys policy‐capable switches. Policy Manager provides the ability to centrally define and configure the authorization levels or policies.

NetSight Inventory Manager is an optional component, providing comprehensive network inventory and change management capabilities.
