“Security” is a word that never fails to elicit a response, but what it means varies greatly depending on context, even when narrowed down to the world of electronic devices. For the consumer, “security” usually means that personal data is not available to anyone other than the specific intended recipients, but for products powered by a microcontroller, there often isn’t much end-customer data to protect. Let’s look at some other definitions of the word “security.” For software developers, “security” might mean that no one can steal their code. For OEMs, “security” could mean that no one can create clones of their device. For service providers that offer a service via an electronic device, “security” often means that no one can use their service without proper authorization or payment. For governments, “security” can mean that the device cannot be infiltrated and used as a weapon as part of a DDoS attack. All of these definitions definitely apply to microcontrollers and products based on them, regardless of market segment.
