Continuity and recovery
Continuity focuses on sustaining critical business outcomes during disruption. Recovery focuses on restoring systems, data, facilities, suppliers, and operations to an intentional, trustworthy state.
Core planning inputs
- Critical functions and dependencies
- Recovery time and data-loss tolerances
- People, facilities, technology, suppliers, and communications
- Degraded operating modes and manual alternatives
- Backups, restoration, and validation
- Authority, escalation, and decision criteria
Testing
Plans should be exercised against realistic failure, dependency, staffing, and communication conditions. A successful backup job is not proof that the organization can recover.
Changed baselines
After a serious incident, the safest target may not be the exact pre-incident state. Recovery can require redesigned trust, new credentials, rebuilt systems, and revised operating assumptions.
BMC v0.2.2 cornerstone expansion
Start analysis of Business Continuity and Recovery with the mission or business outcome, then identify assets, identities, data, trust boundaries, dependencies, expected behavior, and credible failure or abuse cases.
Translate those observations into preventive, detective, responsive, and recovery controls. A mature explanation states not only what the concept is, but also how a practitioner demonstrates that it is working under normal, abnormal, and recovery conditions.
Evidence of effective implementation
- Documented ownership, scope, decision criteria, and permitted exceptions.
- Configuration or architectural evidence tied to a clear control objective.
- Operational telemetry showing expected and unexpected behavior.
- Testing that covers normal use, abuse cases, failure, rollback, and recovery.
- Exceptions that are approved, time bounded, monitored, and revisited.
- Lessons learned that result in updated designs, procedures, detections, or training.
Questions for learners
- Which security properties and business outcomes does Business Continuity and Recovery support?
- What assumptions must remain true for the control or process to work safely?
- What could an attacker, insider, failure, or design error do at each trust boundary?
- Which evidence would prove that controls work continuously rather than only on paper?
- How would the organization respond, restore service, and re-establish trust after failure?
