Model 4: End-System Authorization with Assessment and Remediation

Assisted remediation informs end users when their end‐systems have been quarantined due to network security policy non‐compliance, and allows end users to safely remediate their non‐ compliant end‐systems without assistance from IT operations. The process takes place when an end‐system connects to the network and assessment is performed. End users whose systems fail assessment are notified via web redirection that their systems have been quarantined, and are instructed in how to perform self‐service remediation specific to the detected compliance violations.

Once the remediation steps have been successfully performed and the end‐system is compliant, the end user can initiate an on‐demand reassessment of the end‐system and can be allocated the appropriate network resources, again without the intervention of IT operations.

Implementation

In Model 4, end‐systems can be detected, authenticated, assessed, authorized, and remediated in different ways depending on the whether inline or out‐of‐band network access control is implemented in the Enterasys NAC solution.

Out-of-Band NAC

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

Detection ‐ As described in Model 2.

Authentication ‐ As described in Model 2.

Assessment ‐ As described in Model 3.

Authorization ‐ As described in Model 3.

Remediation ‐ When end‐systems are quarantined by the NAC Gateway, the network must be configured to direct all traffic from the quarantined end‐systems to the NAC Gateway. This can be implemented by configuring policy‐based routing on a router inline with the traffic sourced from quarantined end‐systems. This router would be configured to send all web traffic from quarantined end‐systems to the NAC Gateway, which then serves back the remediation web page to the end user.

The way the router identifies the traffic from quarantined end‐systems differs between a network composed of policy‐enabled switches in the access edge or a network composed of switches implementing RFC 3580 dynamic VLAN assignment in the access edge. For an Enterasys policy‐ enabled edge, the Quarantine policy can be configured to rewrite the Type of Service (ToS) value of HTTP traffic to a particular setting that matches the policy‐based routing configuration. For an RFC 3580 capable edge, the policy‐based routing would be configured to match the source IP address of the HTTP traffic being generated from the subnets that corresponds to the Quarantine and/or Assessing VLAN. In either case, by directing the HTTP traffic from quarantined end‐ systems over to the NAC Gateway, the NAC Gateway will serve back the remediation web page to the noncompliant end‐system.
