Incident Recovery

Overview

Incident recovery begins after immediate containment has reduced active harm, although phases may overlap. Teams rebuild or repair systems, restore data, rotate credentials, validate integrity, reconnect dependencies, and resume operations according to business priorities.

Fast restoration is unsafe when the root cause, persistence, corrupted backups, or compromised identities remain unaddressed. Recovery also involves manual backlogs, customer remediation, reconciliation, regulatory duties, vendor coordination, and monitoring for renewed attacker activity.

Plans should define trusted recovery points, dependency order, acceptance tests, decision authority, rollback, and enhanced observation. Exercises must test whether backups are complete and usable, not merely whether backup jobs reported success. Customer-facing service status should reflect verified recovery, not optimistic estimates.

Incident recovery restores affected systems, data, services, and business processes to a trusted and sustainable state after disruption or compromise. Incident Recovery should distinguish an alert, suspected event, confirmed incident, material impact, and restored service because each state requires different decisions and notifications. Incident Recovery must define the affected service or asset, event severity, business and customer impact, evidence, responsible roles, containment priority, recovery objective, and reporting obligations. Recovery is complete only when operations are restored to a trusted state, backlogs are reconciled, and recurrence risk is controlled.

A production treatment of Incident Recovery should test Incident recovery restores affected systems, data, services, and business processes to a trusted and sustainable state after disruption or compromise within the relevant asset, decision, or service state. The Incident Recovery context record for Incident recovery restores affected systems, data, and services should preserve source data, configuration or policy version, responsible actor, exception, and outcome. Review of Incident Recovery should determine whether safeguards addressing Incident recovery restores affected systems, data, and services changed exposure in practice, not merely whether a document or setting existed.
