SideCopy APT: Connecting lures victims, payloads to infrastructure. Publish/subscribe for IoT means clients don't have to call for updates, which lessens network traffic and processing load. It is never the server (though some mechanisms have been added over the years to simulate server-initiated messages). Then it delivers them to the event handlers that have been registered for the events' type if known, or to the onmessage event handler if no type-specific event handler was established. To display a Web page, the browser sends an original request to fetch the HTML document that represents the page. So, UDP is fast. Multiple users can access the same file simultaneously.

This can include everything from the cable type, radio frequency link (as in a Wi-Fi network), as well as the layout of pins, voltages, and other physical requirements. With HTTP/2, these simple messages are encapsulated in frames, making them impossible to read directly, but the principle remains the same. INVISIMOLE: THE HIDDEN PART OF THE STORY.
