Cybersecurity Briefing — NIST publishes SP 800-53 Revision 5
NIST issued Special Publication 800-53 Revision 5 on 23 September 2020, modernizing federal security and privacy controls with supply-chain and privacy-by-design requirements.
NIST released SP 800-53 Rev. 5 on 23 September 2020, expanding the control catalog to cover supply-chain risk management, privacy engineering, and zero trust-aligned safeguards. It decouples control baselines from the catalog, adds a dedicated Supply Chain Risk Management family, and updates terminology to emphasize outcome-focused, technology-neutral controls.
Federal programs and contractors should map existing security plans to the revised controls, update System Security Plans and Privacy Impact Assessments, and coordinate with procurement to embed the new supply-chain expectations into contracts and vendor due diligence.
