Which of the following is a primary focus of PCI DSS?

The primary focus of PCI DSS (Payment Card Industry Data Security Standard) is on securing payment card transactions. This standard was established to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment. The PCI DSS encompasses a set of comprehensive requirements and guidelines designed to protect sensitive cardholder data from theft and fraud.

By emphasizing security measures related to payment card transactions, the standard aims to minimize the risk of data breaches and enhance overall payment system security. Organizations that comply with PCI DSS demonstrate their commitment to safeguarding customer information and maintaining trust in the payment card ecosystem.

While promoting new payment technologies, developing strategies for fraud prevention, and enhancing customer service protocols may be relevant to the broader context of payment systems, they are not the central focus of PCI DSS. Instead, the main objective is to create and uphold a standard for security practices that directly protects cardholder data during transactions.
