What role does the Policy Set play in Cisco ISE?

The Policy Set in Cisco Identity Services Engine (ISE) is crucial for determining the authorization rules that are applied based on various factors such as user roles and the types of endpoints attempting to access the network. By utilizing a Policy Set, organizations can enforce specific access policies tailored to different users and devices, which enhances security and ensures compliance with organizational guidelines.

When a device or user attempts to connect to the network, ISE evaluates the attributes associated with that entity against the rules defined in the Policy Set. This process involves checking the identity of the user, the type of device, and other contextual information to apply the appropriate level of access. For instance, a corporate laptop may receive different access rights compared to a guest smartphone, reflecting the organization's security posture and access policies.

This functionality is essential for effectively managing network access control, especially in environments where multiple user roles and devices are in play. The Policy Set, therefore, plays a pivotal role in aligning access control with organizational policies and security requirements, making it a foundational component of Cisco ISE's capabilities.
