What is the main focus of the PCI DSS?

The main focus of PCI DSS is to protect cardholder data and enhance payment card security. This standard was established to address the increasing prevalence of data breaches and to safeguard payment card transactions from fraud and misuse. It provides a comprehensive set of requirements that organizations must follow to secure systems and processes that handle payment card information.

By developing a framework for maintaining the confidentiality and integrity of cardholder data, PCI DSS helps organizations mitigate risks associated with payment card transactions and build trust with consumers. The framework covers areas such as encryption, access controls, regular security testing, and maintaining a secure network, all of which are essential for protecting sensitive information.

The other options, while relevant to various business concerns, do not directly align with the primary goal of PCI DSS, which is centered around the security and protection of cardholder data.
