Revisiting IoT Cybersecurity guidance

Driven by these IoT use cases, NIST is revisiting its ‘IoT Device Cybersecurity Guidance for the Federal Government: establishing IoT Device Cybersecurity Requirements, SP 800-213’. This revision adheres to the 2020 Cybersecurity Improvement Act, requiring updates to IoT cybersecurity guidelines every five years.

The Cybersecurity for IoT team is considering potential revisions for SP 800-213. Input from federal agencies is crucial to this process.

Did you Know? NIST Special Publication 800-18r2 focuses on developing system plans that address system-level security, privacy, and Cybersecurity Supply Chain Risk Management Plans.

Key Considerations For Agencies

NIST has asked federal agencies to consider several key points regarding IoT security. This includes how NIST should approach IoT devices dependent on other components.

There is also a need to explore how the risk consideration guidelines can be revised. These revisions should reflect the complexities of IoT products with diverse architectures.

Agencies should also evaluate whether NIST should develop additional catalogs. These catalogs could describe technical capabilities for other IoT product components.

agencies should provide input on what guidelines would be most useful for specific IoT product components, such as software and remote services.

NIST Seeks Feedback

Earlier this month, NIST published Special Publication 800-18r2. The agency is seeking feedback on the draft’s technical accuracy, clarity, and usability.
