 Installing the Cisco Umbrella root CA onto the user’s device is the action that accomplishes the goal of inspecting traffic without alerting end-users. This is because the root CA allows the user’s device to trust the certificates issued by the Cisco Umbrella intelligent proxy, which acts as a man-in-the-middle for SSL sites on Umbrella’s grey list. Without the root CA, the user’s browser would raise errors when accessing those sites, as it would detect an untrusted certificate. By installing the root CA, the user’s browser would accept the certificate and allow the traffic to be proxied and inspected by the intelligent proxy. References:

Explanation

This command uses RADIUS which combines authentication and authorization in one function (packet).

CoA stands for Change of Authorization, which is a feature that allows a RADIUS server to adjust an active client session after it is authenticated. For example, CoA can be used to reauthenticate a client, terminate a client session, or change the VLAN or group policy of a client. CoA is supported by several RADIUS vendors, including Cisco ISE. CoA is defined in RFC 5176 and uses a pushed model, where the request originates from the RADIUS server and is sent to the network device that acts as a listener. CoA requests can have two possible response codes: CoA-ACK (acknowledgment) or CoA-NAK (non-acknowledgment). References :=
