Interactions with the physical world can be tricky – even dangerous! Let's say you have an Internet of Things (IoT) application controlling a chemical process - perhaps exotic chemicals for an aerospace mission. The IoT devices include sensors for temperature, pressure, flow rate, and tank levels and actuators for pumps, heaters and valves – including a dump valve ready to vent high pressure. In this situation it's likely you would have analysis and reporting software running, be receiving sensor readings, and have control of the various pumps, heaters and valves. With IoT, computing can be pushed to the edge via gateways and controllers often running sophisticated applications.
OPEN SOURCE WAY BLOG: Last time I wrote about how the Internet of Things (IoT) is impacting the design of military embedded systems; this month, I'd like to address IoT and security. Specifically, I want to address the security processes involved in managing IoT gateways, which are vital to the successful operation of critical applications.
OPEN SOURCE WAY BLOG: In many ways, embedded systems are the progenitor of the Internet of Things (IoT) – and now IoT is changing key aspects of how we design and build military embedded systems. In fact, the new model for embedded systems within IoT might best be described as design, build, maintain, update, extend, and evolve.
