What aspect of security do PCI-DSS requirements seek to enhance primarily?

The focus of the PCI-DSS (Payment Card Industry Data Security Standard) requirements is centered around enhancing data protection, particularly regarding cardholder information and financial data. PCI-DSS establishes security measures that organizations must implement to ensure that sensitive card data is adequately protected against threats and vulnerabilities, such as data breaches and fraud.

By enforcing strong security standards, PCI-DSS helps organizations maintain the confidentiality, integrity, and availability of credit card transaction data. This includes requirements for encrypting data during transmission, implementing access controls, regularly monitoring and testing networks, and maintaining a vulnerability management program.

While the other options may touch on related themes within the broader scope of cybersecurity or network management, they do not capture the primary aim of PCI-DSS, which is exclusively focused on safeguarding payment card data and ensuring secure processing of financial transactions.
