Is Data Classification considered a core concept of PCI DSS?

Data classification is indeed considered a core concept of the Payment Card Industry Data Security Standard (PCI DSS). This standard focuses on the protection of cardholder data and requires organizations to classify and handle this data appropriately based on its sensitivity. Effective data classification helps organizations identify what types of data they are storing, processing, or transmitting, which in turn informs the security measures that must be implemented to protect that data.

By classifying data, organizations can better understand the risk associated with various types of information and establish adequate controls to mitigate those risks. Furthermore, PCI DSS emphasizes the importance of restricting access to cardholder data on a need-to-know basis, highlighting the necessity of understanding and appropriately managing data sensitivity.

In summary, data classification plays a critical role in establishing the framework for data protection measures and compliance with PCI DSS, ensuring that sensitive cardholder information is properly safeguarded against unauthorized access and breaches.
