💳PCI DSS 2.2Rule: PCI-2-2high

System Configuration Standards

Description

System components within the CDE must be configured per industry-accepted hardening standards (CIS benchmarks, vendor security guides).

⚠️ Risk Impact

Vendor-default configurations include legacy services, weak ciphers, and exposed administrative interfaces. CDE systems with default configurations are immediate compliance findings.

🔍 How EchelonGraph Detects This

PCI-2-2Automated scanner rule

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

🔧 Remediation

Apply CIS benchmarks per platform. Use hardened base images (CIS-published or vendor-hardened AMIs/Marketplace images). Continuous configuration scanning. Document hardening evidence.

💀 Real-World Attack Scenario

A payment processor's MongoDB instance ran with default port (27017) + no authentication 'for internal use'. Internal use turned out to be 'visible to any pod in the K8s cluster'. A compromised application pod scraped the entire transaction history via internal network access.

💰 Cost of Non-Compliance

PCI 2.2 violations: $5K-$100K/month. Avg breach via default-config exposure: $3.2M.

📋 Audit Questions

  • 1.Which hardening benchmarks are applied?
  • 2.Show evidence of CIS benchmark adherence.
  • 3.Are vendor-default credentials removed?
  • 4.How is configuration drift detected?

⚡ Common Pitfalls

  • Vendor-default images deployed without hardening
  • CIS adherence documented but not continuously enforced
  • Internal services running with default credentials 'because they're internal'

📈 Business Value

Hardening baselines eliminate vendor-default attack surface.
