What is PCI?
PCI, or Payment Card Industry Data Security Standard (PCI DSS), is a set of security standards established by the Payment Card Industry Security Standards Council to ensure that organisations handling credit card transactions maintain a secure environment. It encompasses requirements for network security, data protection, access controls, monitoring, and employee training. Compliance is essential to protect cardholder data and prevent breaches, fraud, and other security risks, with non-compliance resulting in fines and legal consequences.
Achieving PCI compliance on AWS
Scope Assessment
Clearly define the scope of your cardholder data environment (CDE) within AWS, including identifying which AWS services, environments, and resources are in-scope for PCI compliance.
Logging and Monitoring
Set up comprehensive logging and monitoring using AWS CloudWatch, AWS CloudTrail, AWS GuardDuty, and third-party security tools. Configure alarms for unusual activities and maintain logs for the required duration.
Risk Assessment and Gap Analysis
Conduct a risk assessment and document your security policies, procedures, and compliance controls. Identify the gaps between the environments in scope of your CDE and PCI controls and create a project plan to resolve these.
Achieving PCI compliance is an ongoing process, not a one-time task. It's essential to keep up with changes in both PCI DSS requirements and AWS services while regularly testing and assessing your environment to ensure ongoing compliance.
