Why Is Device Authentication Necessary for the IoT?
Strong IoT device authentication is required to ensure connected devices on the IoT can be trusted to be what they purport to be. Consequently, each IoT device needs a unique identity that can be authenticated when the device attempts to connect to a gateway or central server. With this unique ID in place, IT system administrators can track each device throughout its lifecycle, communicate securely with it, and prevent it from executing harmful processes. If a device exhibits unexpected behavior, administrators can simply revoke its privileges.
