What is the primary function of 'Authorization Rules' in Cisco ISE?

The primary function of 'Authorization Rules' in Cisco Identity Services Engine (ISE) is to determine access levels based on user and device conditions. This involves evaluating the attributes associated with the user (such as user identity, role, and group membership) and the attributes of the device attempting to connect (such as device type, posture, and compliance status).

Authorization rules play a critical role in network security by allowing administrators to implement granular access control policies that specify what resources users can access and under what conditions. For example, different users might have different access permissions based on their roles in an organization, and devices that meet compliance standards might be granted more privileges than those that do not.

This ability to tailor access based on various conditions directly influences the overall security posture of the network and ensures that only authorized users and compliant devices gain access to sensitive resources. Such rules are essential for enforcing policies that uphold organizational security requirements while still allowing for efficient use of network resources.
