What are NIST 8259 and NIST 8425?

NIST 8259 and NIST 8425 are documents published by the National Institute of Standards and Technology (NIST) in the United States, providing guidelines and recommendations on the security of Internet of Things (IoT) devices. NIST 8259 (officially titled "NIST Special Publication 8259, Recommendations for IoT Device Manufacturers: Foundational Activities and Core Device Cybersecurity Capability Baseline") is a guide for IoT device manufacturers, aimed at helping them understand and implement necessary security measures to protect devices from cyberattacks and data breaches. This document proposes a series of foundational activities and core cybersecurity capabilities, including device identification, device configuration, data protection, logical access control, etc., to ensure the security of IoT devices. NIST 8425 (officially titled "NIST Special Publication 8425, Cybersecurity for IoT Program: Status and Next Steps") is a document about NIST's IoT cybersecurity program, describing the current status and future plans of NIST in developing IoT cybersecurity. This document provides an overview of how NIST addresses IoT security issues, including key areas of research and development, as well as collaboration with other organizations. Overall, these NIST-published documents aim to provide guidance to help enhance the security of IoT devices, reduce potential cybersecurity threats, and promote the trustworthy and sustainable development of IoT technology. Currently, if products meet the NIST IoT cybersecurity standards, they can generally claim to meet the product-level cybersecurity requirements of various U.S. states.
