simple network scenario based on Cisco ISE:

Let's imagine a small company with a network infrastructure consisting of the following components:

Network Devices: This includes switches, routers, and wireless access points (WAPs) that are managed by Cisco ISE.

User Devices: These are the devices that employees use to connect to the network, such as laptops, smartphones, and tablets.

Cisco ISE Server: This is the central server running Cisco ISE software, responsible for authenticating and authorizing users and devices.

Now, let's go through a scenario:

Scenario: Employee Network Access

User Authentication: An employee, let's call her Sarah, comes into the office with her laptop and wants to connect to the company's network. When she tries to connect to the Wi-Fi network, her laptop sends a request to the nearby WAP for network access.

WAP Interaction with Cisco ISE: The WAP forwards Sarah's authentication request to the Cisco ISE server. This request contains Sarah's device details (MAC address, device type, etc.).

Policy Evaluation: Cisco ISE receives the request and checks its policies. It verifies Sarah's identity and the security posture of her device. Policies might include requirements like antivirus software being up-to-date or the device being patched with the latest security updates.

Authorization: After evaluating the policies, Cisco ISE determines that Sarah's laptop meets the company's security standards. It sends an authorization message back to the WAP, allowing Sarah's device to connect to the network.

Network Access Granted: The WAP grants network access to Sarah's laptop, and she is now able to browse the internet, access company resources, and communicate with other devices on the network.

Scenario: Guest Network Access

Visitor Authentication: A visitor arrives at the office and wants to connect to the guest Wi-Fi network. They request access through the captive portal provided by the WAP.

Captive Portal Interaction with Cisco ISE: The captive portal forwards the visitor's authentication request to Cisco ISE, which prompts the visitor to enter some basic information (name, email, etc.) for registration.

Policy Evaluation: Cisco ISE evaluates the registration information provided by the visitor against its policies. It may have policies in place to limit the duration of guest access or restrict certain types of content.

Authorization: If the visitor's registration meets the policy requirements, Cisco ISE sends an authorization message back to the captive portal, allowing the visitor temporary access to the network.

Network Access Granted: The captive portal grants network access to the visitor for the specified duration. They can now use the internet while adhering to the company's security policies.

In these scenarios, Cisco ISE acts as the central authority for authentication, authorization, and policy enforcement, ensuring that both employees and guests can securely access the company's network while complying with security standards and policies.
