Model 2: End-System Authorization

device identity, user identity, and/or location information is used to authorize the connecting end‐ system with a certain level of network access. It is important to note that in this model, network access is not being controlled based on end‐system assessment results. Assessment will be introduced in the next NAC deployment model.

Implementation

In Model 2, end‐systems can be detected, authenticated, and authorized in different ways depending on whether inline or out‐of‐band network access control is implemented.

Out-of-Band NAC

For out‐of‐band NAC utilizing the NAC Gateway, NAC functions are implemented in the following way:

Detection ‐ End‐systems are detected via the receipt of RADIUS packets from an access edge switch attempting to authenticate an end‐system.

Authentication ‐ If the end‐system is 802.1X or web authenticating to the network, the NAC Gateway proxies the RADIUS authentication request to a backend authentication (RADIUS) server to validate the identity of the user/device connecting to the network. For end‐systems that are MAC authenticating to the network, the NAC Gateway can be configured to either proxy the MAC authentication requests to a RADIUS server or locally authorize MAC authentication requests at the NAC Gateway. If only MAC authentication is deployed on the network and the NAC Gateway is configured to locally authorize MAC authentication requests, then a backend RADIUS server is not required for the Enterasys NAC solution.

Authorization ‐ The NAC Gateway allocates the appropriate network resources to the end‐system based on device identity, user identity, and location. For Enterasys policy‐enabled edge switches, the NAC Gateway formats information in the RADIUS authentication messages that directs the edge switch to dynamically assign a particular policy to the connecting end‐system. For RFC 3580‐ capable edge switches, the NAC Gateway formats information in the RADIUS authentication messages (in the form of RFC 3580 VLAN Tunnel attributes) that directs the edge switch to dynamically assign a particular VLAN to the connecting end‐system. The NAC Gateway may deny the end‐system access to the network by sending a RADIUS Access‐Reject message to the edge switch or assign the end‐system a set of network resources by specifying a particular policy or VLAN to assign to the authenticated end‐system on the edge switch.

Inline NAC

For inline NAC utilizing the Layer 2 or Layer 3 NAC Controller, NAC functions are implemented in the following way:

Detection ‐ End‐systems are detected via the receipt of RADIUS packets from an access edge switch attempting to authenticate an end‐system.

Authentication ‐ One of two authentication configurations can be implemented on the NAC Controller. Authentication can be disabled altogether, trusting that the downstream infrastructure devices authenticated the end‐system and permitted network access. Alternately, MAC registration can be implemented for new devices connecting to the network, where a username and password and/or a sponsor username and password must be validated against a backend LDAP‐compliant database before network access is permitted.

Authorization ‐ The NAC Controller allocates the appropriate network resources to the end‐ system by assigning a policy locally on the controller to the traffic sourced from the end‐system.
