Summary

What it is

A defense-in-depth backup architecture combining S3 Object Lock, air-gapped replication, anomaly detection on access patterns, and multi-account isolation to protect against ransomware attacks.

Where it fits

This architecture addresses the evolving threat where ransomware targets backup infrastructure itself. By layering immutable storage, network isolation, behavioral detection, and separate credential domains, it makes backup data survivable even when production and primary backup systems are compromised.

Misconceptions / Traps
  • Object Lock alone is not sufficient. Sophisticated attacks target credentials and management planes. The architecture requires multi-account isolation, separate credential chains, and anomaly detection in addition to immutability.
  • Air-gapped does not mean disconnected forever. Modern air-gapped designs use narrow, one-way replication channels with strict access controls — not physical disconnection.

Definition

What it is

A defense-in-depth backup design combining Object Lock immutability, air-gapped or cross-account replication, anomaly detection on S3 events, and isolated recovery environments to protect and recover from ransomware attacks.

Why it exists

Individual protections (encryption, access controls, backups) are insufficient when ransomware compromises administrative credentials. A resilient architecture layers multiple independent controls so no single compromise can destroy all recovery options.

Primary use cases

Enterprise ransomware protection, critical infrastructure backup, financial services data protection, healthcare data resilience.
