What does CDE stand for in the PCI DSS context?

• A. Card Data Encryption
• B. Cardholder Data Environment
• C. Centralized Data Exchange
• D. Customer Data Entity

Answer: (B)

CDE stands for Cardholder Data Environment, the set of systems and assets that store, process, or transmit cardholder data and the security controls surrounding them. This environment defines the scope of a PCI DSS assessment, meaning all components that touch cardholder data (and the controls that protect that data) are in scope for applying PCI requirements. The reason this is the best answer is that PCI DSS centers its guidance on securing that environment, not on encryption methods or unrelated concepts. The other options don’t fit because they refer to encryption (a control), a generic data exchange term, or an entity, none of which define the scope or boundary used by PCI DSS.
