What is a primary benefit of using Cisco ISE for network segmentation?

Using Cisco Identity Services Engine (ISE) for network segmentation offers significant advantages, particularly through its ability to enable dynamic segmentation. This feature enhances security by allowing network administrators to tailor access controls based on user identities, device types, and contextual information associated with the endpoint attempting to access the network.

Dynamic segmentation facilitates real-time adjustments to network policies. For example, when a device connects to the network, Cisco ISE can automatically assign it to the appropriate network segment based on pre-defined policies. This ensures that each user or device only has access to the resources that are necessary for their role, thereby minimizing the potential attack surface and limiting lateral movement within the network.

In contrast to static segmentation methods, which require manual configuration and can be inflexible, dynamic segmentation allows for a more scalable and agile network security model. It can react to changes in the network environment, accommodating new devices or shifting roles without needing extensive reconfiguration. This is essential in today’s fast-paced digital landscape where threats evolve rapidly, and organizations need to be able to adapt their security posture accordingly.
