Protect long-lived records first

This page is a labelled illustration, not a real organisation.

The case is a clinic with long-lived health records on a vendor system, and a device whose firmware signature check cannot be updated in the field.

Walk the checklist​

The records are first because confidentiality still matters after 10 years. The EU NIS Cooperation Group roadmap, 11 June 2025, treats that case as high-risk where confidentiality is protected by public-key cryptography. NIST IR 8547, October 2026, describes harvest-now, decrypt-later for that confidentiality problem.

The firmware root is first for a different reason. The UK NCSC timelines, modified 3 August 2026, include long-lived hardware roots of trust in the 2028 plan row. NIST IR 8547 says that where a firmware or trust root cannot update its signature check later, and it will still be in use when a cryptanalytically relevant quantum computer exists, the devices should be designed to require quantum-resistant signatures on the executable code.

The clinic's browsers and laptops stay on the keep-updated path. The NCSC timelines say that for organisations that rely on commodity IT, such as standard browsers, operating systems, and mobile devices, migration should happen as vendors update those services.

Outcome​

One page: the two assets, why each is first, the vendor question, and the date of the next pass.
