Recovery, Resilience & Cyber Recovery

Recovery, resilience, and cyber recovery is the discipline of restoring an organization to working order after a security incident — and doing it without re-inheriting the compromise. NIST CSF 2.0 elevated Recovery to a first-class function in 2024 for a reason: post-ransomware-decade, the question 'how do we get back to operational state in a known-clean environment?' turned out to be a fundamentally different problem from detection or response.

The operational core is layered: immutable backups (write-once-read-many storage that can't be rewritten by attackers with admin credentials), air-gapped or isolated cyber recovery vaults (Dell PowerProtect Cyber Recovery, Rubrik Security Cloud, Cohesity FortKnox), integrity verification (cryptographic checks that backups haven't been tampered with), and rehearsed restore orchestration (the SOP for which systems come up first, in what order, on what infrastructure). The 3-2-1 backup rule (3 copies, 2 different media, 1 off-site) became 3-2-1-1-0 (add 1 immutable copy, 0 errors after recovery testing) once ransomware groups started hunting backups specifically.

The discipline also covers Business Continuity Management (BCM), Disaster Recovery (DR), Recovery Time and Recovery Point Objectives (RTO/RPO), tabletop exercises (the rehearsals that surface gaps before a real event), and the legal/regulatory dimension of breach notification timelines. After Colonial Pipeline (2021) and the Change Healthcare attack (2024), recovery is no longer a checkbox under IT operations — it's a board-level program with its own funding, staffing, and tested cadence.
