How does VPN Integration work with Cisco ISE?

VPN Integration with Cisco Identity Services Engine (ISE) is primarily designed around the principles of authentication and authorization through the ISE policies. When users connect to a VPN, Cisco ISE evaluates their identity and the attributes of their connection against defined policy rules. This includes checking credentials, such as usernames and passwords, as well as other contextual data like device type, user role, and even the state of the device.

In this scenario, the correct answer highlights that users are authenticated and authorized based on the policies set within Cisco ISE. These policies dictate what access rights and permissions users possess once they are connected. This could involve requiring multi-factor authentication, validating endpoint compliance, and ensuring that users only receive access to the resources they are permitted to use according to their roles or other conditions set by the organization.

Through this dynamic process, Cisco ISE enhances security by ensuring that only properly authenticated users and compliant devices gain access to the network, thereby minimizing potential vulnerabilities associated with unauthorized access.
