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

# Verify isolated recovery network is segmented
# No routes to production should exist
ip route show | grep -v "192.168.100.0/24"  # recovery VLAN only

# Verify backup catalog is accessible
restic snapshots --repo s3:s3.amazonaws.com/backup-bucket --password-file /etc/restic/pw
