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.

Model 4: End-System Authorization with Assessment and Remediation

This NAC deployment model implements all five NAC functions: detection, authentication, assessment, authorization, and remediation. In Model 3, end‐systems and end users connected to the network are authorized based on the device identity, user identity, location, and/or security posture information. And, as explained in Model 3, it was not necessary to quarantine noncompliant end‐systems while phasing in the NAC solution on the network. However, once a restrictive authorization level is allocated to noncompliant end‐systems, it is important to inform the end user of the restrictions and provide the steps they can execute for self‐repair of the device. This is the process of assisted remediation, which is the NAC function introduced in Model 4.
