The Interagency International Cybersecurity Standardization Working Group (IICS WG), through its Internet of Things (IoT) Task Group, developed NIST Interagency Report (NISTIR) 8200 to explore the current state of international cybersecurity standards development for IoT. The intended audience is both the government and the public. The purpose is to inform and enable policymakers, managers, and standards participants as they seek timely development of and use of cybersecurity standards in IoT components, systems, and services.
