The audit came back with red marks. Your AWS environment is powerful, but it’s not PCI DSS compliant yet. And in payments, that gap between almost and certified can cost millions.
AWS offers tools to meet PCI DSS, but they don’t configure themselves. The standard is strict: limit access, encrypt data, monitor everything that touches cardholder information. If you’re running workloads that handle payment data in AWS, you need control over user permissions, network segmentation, logging, and patching — all at scale, without human error opening a hole.
Start with the AWS shared responsibility model. AWS manages the physical security and core infrastructure. You own the configuration of services, identity management, and the security of the workloads you deploy. That means enabling AWS Config to track changes. GuardDuty for intrusion detection. CloudTrail to log API calls. Key Management Service to control encryption keys. VPCs to isolate environments. Security Hub to keep it all visible in one place.
PCI DSS demands strong access control. On AWS, that’s Identity and Access Management (IAM) policies locked down to the principle of least privilege. Multi-factor authentication for all accounts. Rotating access keys automatically. Network ACLs to enforce rules. Systems Manager for automated patch management.
