📋ISO 27001 A.8.13Rule: ISO27001-A813critical

Information Backup

Description

Backup copies of information, software, and systems shall be maintained and regularly tested in accordance with the agreed topic-specific policy on backup.

⚠️ Risk Impact

Ransomware specifically targets backups. Backups in same account/region as production are encrypted in same attack. Modern adversaries verify backup destruction before triggering encryption.

🔍 How EchelonGraph Detects This

ISO27001-A813Automated scanner rule

EchelonGraph's Tier 1 Cloud Scanner automatically checks for this condition across all connected cloud accounts. Violations are flagged as critical-severity findings with remediation guidance.

🔧 Remediation

Cross-account, cross-region, write-once-read-many backups. Quarterly restore test. MFA-required deletion. Cloud-native immutable backup (S3 Object Lock, GCS Bucket Lock, Azure Blob Lock).

💀 Real-World Attack Scenario

A SaaS company hit by LockBit 3.0 had backups in same AWS account as production. Attackers (with admin) encrypted backups too. Forced $3.4M ransom negotiation. Air-gapped backups would have eliminated the leverage.

💰 Cost of Non-Compliance

Ransomware + destroyed backups: avg $5.13M (Coveware 2024). Without ransom paid: avg 23 days downtime.

📋 Audit Questions

  • 1.Backup storage — same account/region as production?
  • 2.MFA required for deletion?
  • 3.Last restore test?
  • 4.Immutability configuration?

⚡ Common Pitfalls

  • Backups in same account as production
  • Restore procedures never tested
  • Backup retention met but immutability not enforced

📈 Business Value

Air-gapped, tested backups convert ransomware from existential to operational.
