A ransomware recovery plan defines how your organization restores systems and data after an attack without relying on the attacker. It covers protected and immutable backups, the order in which systems are restored, how identity systems are rebuilt, how clean environments are verified before reconnecting, and who makes decisions. Recovery readiness is what turns a ransomware attack from a business-ending event into a disruptive but survivable one.
Key Takeaways
- Attackers target backups first, so keep immutable, isolated copies.
- Recover identity (Active Directory or Entra ID) early; everything depends on it.
- Define recovery time objectives (RTO) and recovery point objectives (RPO) per system.
- Restore into a clean, verified environment to avoid reinfection.
- Test restores regularly; untested backups are assumptions, not plans.
Before an Attack: Preparation Checklist
- Follow a 3-2-1 approach: three copies, two media types, one offsite, with at least one immutable or air-gapped copy.
- Back up Microsoft 365 data, Azure workloads, servers and SaaS apps.
- Protect backup consoles with separate credentials and MFA.
- Document system dependencies and recovery order.
- Keep offline copies of the plan, contacts and critical passwords in a secure vault.
- Run tabletop exercises and restore tests.
Recovery Priorities
| Priority | Systems | Why |
|---|---|---|
| 1 | Identity and access (AD, Entra ID, privileged accounts) | Required to authenticate everything else |
| 2 | Core infrastructure (networking, DNS, backup platform) | Enables restoration |
| 3 | Communication (email, Teams, phones) | Coordinates the business |
| 4 | Revenue-critical apps (ERP, line-of-business, customer portals) | Restores operations |
| 5 | Remaining systems and user data | Full recovery |
The First 24 Hours
- Activate your incident response plan and incident commander.
- Isolate affected systems; do not power off before evidence is considered.
- Notify your cyber insurer and legal counsel as your policy requires.
- Disable compromised accounts and reset privileged credentials.
- Confirm backup integrity and identify the last clean restore point.
- Communicate through out-of-band channels.
Restore Safely
- Rebuild in a clean environment or isolated network segment.
- Scan restored systems before reconnecting.
- Patch the vulnerability or access path the attacker used, then tighten your patch management process.
- Monitor closely for signs of persistence.
After Recovery
Run a lessons-learned review, strengthen identity controls with Conditional Access and privileged access management, and update RTO and RPO targets based on what you experienced.

Frequently Asked Questions
Should we pay the ransom?
Law enforcement agencies generally advise against paying, as payment does not guarantee recovery and may fund further crime. The decision involves legal, insurance and regulatory considerations, so involve counsel.
What is an immutable backup?
An immutable backup cannot be changed or deleted for a set retention period, even by administrators, which protects it from ransomware and malicious insiders.
How quickly can we recover from ransomware?
It depends on preparation, backup design and scope of the attack. Organizations with tested, immutable backups and clear priorities recover much faster.
Does Microsoft 365 need separate backup?
Microsoft provides service resilience and retention features, but many organizations add third-party or Microsoft 365 Backup for point-in-time recovery and longer protection.
What are RTO and RPO?
Recovery time objective is how long a system can be down; recovery point objective is how much data loss, measured in time, is acceptable.
How often should we test restores?
Test critical system restores at least quarterly and run a full recovery exercise annually.
