Azure IoT Edge Security

Abstract

Don’t be misled by this chapter. You might be tempted to think that because this chapter is one of the last chapters in the book, it’s an add-on topic to the Azure IoT Edge platform. That couldn’t be further from the truth. In fact, many of the other chapters provide the context necessary to properly understand the way Azure IoT Edge is secured. Security is the core of Azure IoT Edge. All of the edge runtime components we have discussed previously are all managed by the edge security service. No code is installed or started on an edge device without first being initiated by the security service. But, to be truly secure, the edge device hardware must also be secure. It is not enough for the software to be secure. If the hardware can’t enforce the requirements, then all the security baked into the edge runtime will still not yield a secure solution.
