What is the function of Authentication Rules in Cisco ISE?

Authentication Rules in Cisco Identity Services Engine (ISE) play a crucial role in managing how users authenticate to the network. By dictating the order and method for authenticating users, these rules ensure that ISE can properly evaluate the credentials provided by a user and determine whether they meet the necessary requirements for access.

The primary function of these rules involves specifying different authentication methods, such as 802.1X, MAB (MAC Authentication Bypass), and WebAuth, and setting the sequence in which these methods are applied. For instance, if a user attempts to connect to the network, the ISE will follow the defined authentication rules step-by-step, trying each method in the specified order until it finds one that successfully authenticates the user. This process is essential to providing a flexible and secure authentication framework, allowing organizations to tailor their security measures according to different user scenarios.

Other options do not accurately reflect the purpose of Authentication Rules. Setting network bandwidth, defining security levels, and listing potential user types are not functions of authentication rules within Cisco ISE. Instead, these tasks are managed elsewhere in the ISE configuration.
