Use Scenarios

This chapter describes four NAC use scenarios that illustrate how the type of NAC deployment is directly dependent on the infrastructure devices deployed in the network. For some network topologies, inline network access control utilizing the NAC Controller may be required while for other network configurations, the NAC Gateway implementing out‐of‐band NAC may be used.

The Enterasys NAC solution is capable of implementing network access control for all four use scenarios as well as environments with mixed use scenarios that may require the concurrent deployment of the NAC Gateway and the NAC Controller. Regardless of the scenario that is deployed, all NAC Gateways and NAC Controllers are centrally managed by the NetSight NAC Manager software application.

Summary

3-13

 

 

For the intelligent wired access edge and intelligent wireless access edge use scenarios, the term “intelligent” refers to a network topology where the access edge is composed of Enterasys policy‐ enabled switches capable of supporting authentication and policy enforcement, or third‐party switches capable of supporting authentication and dynamic VLAN assignment as defined in RFC 3580.

Scenario 1: Intelligent Wired Access Edge

In the intelligent wired access edge use scenario, the edge switches that compose the network access layer are capable of providing authentication (802.1X, web‐based, or MAC) for connecting end‐systems, and they are also capable of being an authorization point for these end‐systems through Enterasys policy and/or dynamic VLAN assignment as specified in RFC 3580.

For this use scenario, the NAC Gateway appliance is deployed for out‐of‐band network access control, leveraging the intelligent infrastructure devices in the access edge as the authorization point for connecting end‐systems.

It is important to note that Enterasys policy‐enabled switches provide increased security over third‐party switches that support RFC 3580. By using port‐level granular traffic control, users quarantined with Enterasys policy can be restricted from communicating with other quarantined users, even if co‐located on the same VLAN. In a Quarantine VLAN as implemented on third‐ party RFC 3580 capable switches, a quarantined user poses a threat to other quarantined users
