Testing Ransomware Recovery Procedures
When to Use
Use this skill when:
- Validating that ransomware recovery plans actually work under realistic conditions
- Measuring RTO (Recovery Time Objective) and RPO (Recovery Point Objective) against business requirements
- Testing backup restore operations to confirm data integrity and completeness after simulated encryption
- Conducting tabletop exercises or live recovery drills for ransomware scenarios
- Auditing disaster recovery readiness as part of compliance or cyber insurance requirements
Do not use for active incident response during a live ransomware attack. Use dedicated IR playbooks instead.
Prerequisites
- Isolated recovery test environment (air-gapped or network-segmented lab)
- Access to backup infrastructure (Veeam, Commvault, Rubrik, AWS Backup, Azure Backup)
- Documented RTO/RPO targets per application tier from business impact analysis
- Backup copies available for restore testing (production replicas or test snapshots)
- Recovery runbooks with step-by-step procedures for each critical system
Workflow
Step 1: Define Recovery Test Scope
Identify critical systems and their tiered recovery targets:
| Tier | System Type | RTO Target | RPO Target | Example |
|---|
| Tier 1 | Mission-critical | < 1 hour | < 15 min | Active Directory, core database |
| Tier 2 | Business-critical | < 4 hours | < 1 hour | ERP, email, CRM |
| Tier 3 | Business-operational | < 24 hours | < 4 hours | File shares, internal apps |
| Tier 4 | Non-critical | < 72 hours | < 24 hours | Dev/test, analytics |
Step 2: Prepare Test Environment
