Source Facts

NCSC's new guidance collection, published on 1 October, is aimed at organisations whose operations would be seriously affected by failure of critical digital systems. The response section covers immediate actions, restoring minimum viable operations and longer-term rebuilding.

Preparedness covers business continuity, people, technical recovery and major decisions. Risk reduction covers identifying critical systems, reducing exposure, limiting intrusion impact, detection and response. This is a planning framework, not an automatic recovery service.

Next Steps for Businesses / Editorial Observations

Organisations can define an actionable order for restoring business operations, then list the data, accounts and people each step depends on.

Next steps you can take

  • Confirm the minimum services that must remain available during downtime and the alternative procedures.
  • Rehearse recovery of critical systems in an isolated environment and record unresolved dependencies.
