Out-of-Band NAC Design Procedures

Figure 5-7 Service for the Assessing Role

Note that it is not mandatory to assign the Assessment Policy to a connecting end‐system while it is being assessed. NAC can be configured to assign the policy role received from the RADIUS server or the Accept Policy to the end‐system while it is being assessed. In this way, the end‐ system can be granted immediate network access without mandating that the end user wait for assessment to be complete before full network resource allocation is granted. If NAC is configured to return the policy role received from the RADIUS Server, it is necessary that the enterpriseʹs business‐specific policy roles are configured to allow access to the appropriate network resources for communication with the assessment servers during assessment. This can be implemented by associating the Assessing service shown in Figure 5‐7 to all business‐specific policy roles in the NetSight Policy Manager configuration.

Quarantine Policy

The Quarantine Policy is used to restrict network access to end‐systems that have failed assessment. For Enterasys policy‐enabled switches, a corresponding Quarantine policy role (created in Policy Manager) should deny all traffic by default while permitting access to only required network resources such as basic network services (ARP, DHCP, and DNS).

If the NAC deployment implements remediation, the services associated to the Quarantine Policy must be configured to allow all HTTP traffic onto the network, in addition to other basic IP services such as ARP, DNS, and DHCP as shown in Figure 5‐8.
