The security problem in the Internet of Things (IoT) landscape is one of the most pressing challenges in modern computing. The combination of a large attack surface with the constrained resources typical of the embedded systems makes IoT infrastructure a particularly attractive target for attackers. The problem is structural in nature: the existing operating systems that run these devices were not designed with security as a foundational principle, and attempting to retrofit security onto architectures not originally designed to support them has proven to be insufficient. The answer to this problem lies in a technological stack conceived with security as its primary design objective.
