Recover (RC): what it demands and how it is evidenced

The shortest function with the most expensive failures: executing recovery plans and communicating during restoration. Recovery is where untested backups, undocumented dependencies and silent stakeholders turn a contained incident into a prolonged outage.

The categories inside Recover

RC.RP
Incident recovery plan execution

Recovery executed per plan: restoration priority by criticality, integrity of backups verified BEFORE restoration, systems confirmed clean and operational.

RC.CO
Incident recovery communication

Restoration progress communicated to internal and external stakeholders — customers, regulators, partners — with consistent messaging.

Category identifiers reference NIST CSF 2.0 (26 February 2024) — nist.gov/cyberframework.

Where profiles fall short

Restoring the compromise along with the data

RC.RP includes verifying backup integrity and system cleanliness before restoration — restoring from a backup taken after initial compromise re-infects the environment.

Recovery order improvised

Without criticality-driven restoration priorities (fed by ID.AM), teams restore what is easy instead of what the business needs first.

Silence during restoration

RC.CO failures compound reputational damage; stakeholders fill communication vacuums with worst-case assumptions.

Evidence that holds up

  • Recovery plans with criticality-ordered restoration priorities (RC.RP)
  • Backup integrity verification steps and clean-state confirmation records
  • Recovery exercise results with timings vs objectives
  • Communication templates and sampled updates from incidents/exercises (RC.CO)

Recover FAQ

How does Recover differ from business continuity?

Recover addresses restoration after cybersecurity incidents specifically; BC/DR is broader. They share machinery — which is why ISO 27001 A.5.30 (ICT readiness for BC) and CSF RC evidence largely overlap.

What changed in Recover under CSF 2.0?

Sharper expectations on verifying backup integrity before restoration and on structured recovery communication — the two failure modes ransomware incidents exposed.

What metrics prove recovery capability?

Exercise-measured restoration times against defined objectives (RTO-style), backup restore success rates, and post-exercise lessons closed — numbers, not adjectives.
