Awesome post overall. I liked when you said that the biggest threat to ZigBee was user ignorance – indeed that can be a huge detriment with any technology. Question – assume you have just been asked to deploy a ZigBee device on a corporate network – what would be the first 5 steps you would take to ensure that you as the user / installer are not the weakest link from a security perspective. Provide at least one example as you comment on this.
