Now, if my network were a castle and bad packets or DDoS attacks looked like Catapults and flaming arrows. It would be very obvious to someone viewing that scene that we are at war and possibly losing. If my walls were huge and the arrows few you would not worry. If my walls were low and small and the arrows many you would realize we are losing. This is an image that can be looked at and understood almost universally, without the need for years of training on what the debug logs in a firewall look like.
