Troubleshooting

Securely delete any sensitive authentication data (pre-authorization data) used for debugging or troubleshooting purposes from log files, debugging files, and other data sources received from customers, to ensure that magnetic stripe data, card validation codes or values, and PINs or PIN block data are not stored on software vendor systems. These data sources must be collected in limited amounts and only when necessary to resolve a problem, encrypted while stored, and deleted immediately after use.

• Collect sensitive authentication data only when needed to solve a specific problem.
• Store such data only in specific, known locations with limited access.
• Collect only the limited amount of data needed to solve a specific problem.
• Encrypt sensitive authentication data while stored.
• Securely delete such data immediately after use.
