PCI DSS 6.5.6: Remove Test Data Before Production
Test data and test accounts left in production systems create significant security vulnerabilities and compliance failures. PCI DSS 6.5.6 requires you to systematically identify and remove all test artifacts before systems process live cardholder data. This control prevents attackers from exploiting dormant test accounts or predictable test data to compromise your payment environment.
What this means
Before deploying any system component to production, you must completely remove all test data, test accounts, and testing credentials. This includes dummy customer records, test payment methods, debugging accounts, and any other artifacts created during development and quality assurance phases. The requirement applies to all system components including databases, applications, and infrastructure that will handle or support cardholder data environments.
How to comply
- 1.Maintain an inventory of all test data and test accounts created during development and testing phases
- 2.Establish a pre-production checklist that includes verification of test data removal before any system deployment
- 3.Implement automated scanning tools to detect and flag common test data patterns and default test credentials
- 4.Document the removal process for each test data set with timestamps and responsible parties
- 5.Conduct final verification by authorized personnel that all test accounts and data have been removed
- 6.Retain evidence of removal (logs, screenshots, or audit trails) for compliance audit purposes
Evidence auditors look for
- Pre-production deployment checklists signed off by QA and security teams confirming test data removal
- Automated scan reports showing no test accounts or dummy data in production environments
- Database backup and restore logs documenting test data purged before production cutover
- Change management tickets documenting test credential deactivation and removal dates
- Security scan reports from vulnerability tools confirming no default or test credentials remain active
