NIST Frameworks

The National Institute of Standards and Technology (NIST) is the US federal agency responsible for measurement science. In the digital age, it is the de facto authority on cybersecurity compliance.

NIST CSF (Cybersecurity Framework)

The voluntary guidance for critical infrastructure. Built on five functions: Identify, Protect, Detect, Respond, Recover.

  • Core Guidance
  • Implementation Tiers
  • Profiles

SP 800-171 & 800-53

Specific publications for federal information systems.

  • NIST 800-53Security and Privacy Controls for Federal Information Systems (Strict).
  • NIST 800-171Protecting Controlled Unclassified Information (CUI) in Non-Federal Systems.

Metrology & Physical Standards

Before cybersecurity, NIST was (and is) the keeper of weights and measures. From the atomic clock that syncs GPS satellites to the standard kilogram, NIST defines the physical reality of commerce.
