Which type of regulation governs credit card transactions as a part of cloud operations?

The Payment Card Industry Data Security Standard (PCI DSS) governs credit card transactions in cloud operations. Managing Cloud principles explain that PCI DSS establishes security requirements for organizations that store, process, or transmit cardholder data.

PCI DSS applies to cloud service providers and cloud customers involved in payment processing. It mandates controls such as encryption, access restrictions, monitoring, vulnerability management, and secure system configurations to protect cardholder information.

GLBA applies to financial institutions, SOX governs financial reporting controls, and HIPAA protects healthcare data. Therefore, PCI DSS is the correct regulation for credit card transactions.
