🎯
Key Takeaways
- •A PCI-compliant VPC isolates the CDE in private subnets with no direct internet route — all external access via NAT Gateway or PrivateLink
- •AWS PrivateLink is the correct pattern for connecting to payment processors without traversing the public internet
- •Terraform with remote state in S3 + DynamoDB locking is the standard IaC pattern for regulated AWS infrastructure
- •WAF + Shield Advanced protects payment APIs from L7 attacks and DDoS — Shield Advanced also gives you the DDoS Response Team
- •CI/CD pipelines in fintech must enforce: SAST scanning, dependency vulnerability checks, and mandatory approval gates before production
