Model 1: End-System Detection and Tracking

RADIUS Access‐Accept or Access‐Reject message received from the upstream RADIUS server, is returned without modification to the access edge switch, to permit end‐system access to the network. For MAC authentication, a RADIUS Access‐Accept message is returned to the access edge switch without modification, based on a RADIUS Access‐Accept message received from the upstream RADIUS server or local authorization of MAC authentication requests. The authenticating end‐system is provided access to the network based on the configuration of the access edge switch.

Inline NAC (Layer 2)

For inline NAC utilizing the Layer 2 NAC Controller, an end‐system can be detected in multiple ways. An end‐system can be detected simply by transmitting data traffic not previously seen by the NAC controller. In this case, the traffic is forwarded through the NAC Controller to the traffic destination, and has no impact on the connectivity of the end‐system. In another method, end‐ systems are detected with the authentication of downstream end‐systems via 802.1X, web‐based, and/or MAC authentication on the NAC Controller. These authentication requests may or may not be proxied upstream depending on the NAC configuration.

Inline NAC (Layer 3)

For inline NAC utilizing the Layer 3 NAC Controller, an end‐system is detected simply by transmitting data traffic sourced from an IP address not previously seen by the NAC controller. The traffic is forwarded through the NAC controller to the traffic destination, and has no impact on the connectivity of the end‐system.

Features and Value

There are two key pieces of functionality and value propositions supported by Model 1:

End-System and User Tracking

Model 1 supports the ability to track end‐systems by MAC address, as the device moves from switch port to switch port, and map the device identity to its IP address every time it connects. Furthermore, the associated user can also be mapped to the device and IP address, as long as a username‐based authentication method (802.1X or web‐based authentication) or MAC Registration is implemented with the NAC Gateway, or if end users are configured to login to a Microsoft Windows domain with the NAC Controller using Kerberos snooping functionality.

Using these methods, the Enterasys NAC solution can identify who, what, when, and where devices and users connect to the network. This information is maintained centrally in the NetSight NAC Manager database, providing important historical data that can be used for auditing or troubleshooting purposes. In addition, this information can be easily searched to identify which port a particular user is currently connected to on the network, or which device is currently allocated a particular IP address. This binding (IP address, MAC address, username, location), which is maintained over time for each end‐system, is useful for compliance and auditing purposes, and for planning the subsequent rollout of the next NAC deployment model.

IP-to-ID functionality for Security Information Management (SIM)

This NAC deployment model enables SIM systems such as the Enterasys Dragon Security Command Console (DSCC), to display user‐focused information about assets on the network. Traditionally, SIM systems yield device‐focused information (such as IP address) about detected network threats, through the correlation, normalization, and prioritization of events
