NAC Solution Overview

Assessment

Determine if the device complies with corporate security and configuration requirements, such as operating system patch revision levels and antivirus signature definitions. Other security compliance requirements might include the physical location of the device and the time of day the connection attempt is made.

Authorization

Determine the appropriate network access for the connecting device based on the authentication and/or assessment results, and enforce this authorization level to the end‐system. The authorization level can be determined based on the deviceʹs location, MAC address, and security posture (as determined by the assessment results), in addition to the identity of the user/device validated through authentication.

The end‐system can be authorized for network access using different techniques, such as reconfiguring access edge switches or leveraging a specialized NAC appliance deployed in the transmission path of end‐system data traffic. Inline and out‐of‐band NAC implementations use different techniques for authorizing end‐systems on the network, each with unique advantages and disadvantages as discussed later in this chapter.

Remediation

Enable end users to safely remediate their non‐compliant end‐systems without impacting IT operations. With remediation, users can be notified when their system is quarantined for network security policy non‐compliance, and they can be directed to perform self‐service remediation techniques specific to the detected compliance violation. Notification methods include web redirection via a captive portal, email notification, pop‐up messages, and messenger service integration, among others.

The remediation process includes updating the device to meet corporate security requirements (for example, updating operating system patches and antivirus signatures) and reinitiating the network access process. Network resources can be automatically reallocated to end‐systems that have successfully performed the remediation steps, without the intervention of IT operations.

Deployment Models

The five key NAC functions described above do not need to be implemented concurrently in a NAC deployment. For example, to support MAC registration for guests and other users on the network, the detection, authentication, and authorization functionalities can be implemented without the assessment functionality. This allows an IT department to gain visibility into who is using which devices on the network while allowing only valid users to enter the network.

As another example, the assessment functionality can be added to the detection, authentication, and authorization of end‐systems without the remediation functionality, allowing for the auditing, but not quarantining, of connecting end‐systems. This provides visibility into the security posture and configuration of connecting end‐systems without impacting device network connectivity, and can be used for auditing and software update purposes by the IT department.

The four NAC deployment models described below build on each other by implementing subsets of the five key NAC functions. Each model provides particular aspects of NAC functionality, supporting the requirements of diverse enterprise environments. With each subsequent model, the additional NAC functionality can be enabled without the need to replace pieces of the Enterasys NAC solution.
