What does PCI DSS stand for?

Payment Card Industry Data Security Standard is the correct term for PCI DSS. This standard is a set of security protocols and requirements designed to protect cardholder data associated with payment card transactions. Organizations that handle credit and debit cards must comply with these standards to ensure the protection of sensitive customer information and maintain the integrity of payment transactions.

The reason why this answer is appropriate is rooted in the key focus areas of PCI DSS, which include the protection of cardholder data, secure network architecture, and ongoing vulnerability management. By adhering to these standards, businesses can significantly reduce the risk of data breaches and fraud, securing both their customers and their operations.

In contrast to the other options, the terms provided do not accurately represent the established standards or organizations associated with card payment security. The focus on "Payment Card Industry" is crucial, as it encompasses all entities involved in the transaction process, whereas alternative terms either misinterpret or do not exist within the context of data security specific to payment cards.
