3. Environment monitoring sensors

Sensors are necessary for many connected devices, especially things that adjust based on the environment or how many people they sense. While small, they're not necessarily secure.

"Sensors for environment monitoring and RFID tags for supply chain are typical devices that are connected but have no built-in security in order to keep the cost of devices low enough that it can be widely deployed/adopted," Raullen Chai, co-founder of blockchain company IoTeX, said. "Security doesn't come for free; it requires a certain amount of computation, storage, and power. For IoT, there is a natural tradeoff among usability, security, privacy and cost."
