Which act was designed to ensure the security of credit card transactions?

The Payment Card Industry Data Security Standard (PCI DSS) was specifically established to enhance the security of credit card transactions and protect sensitive payment card information. It was developed by major credit card companies to set comprehensive security requirements for organizations that handle credit card data.

This standard outlines a series of security measures that organizations must implement to prevent data breaches and fraud. Compliance with PCI DSS helps ensure that businesses engage in secure practices while processing, storing, and transmitting credit card information. By adhering to these standards, businesses can significantly reduce the risk of unauthorized access and ensure that customer payment data is handled with a high level of security.

In contrast, the other options do not focus specifically on credit card transaction security. The Personal Information Protection and Electronic Documents Act primarily deals with the protection of personal information in Canada. The Computer Fraud and Abuse Act addresses computer-related offenses, while the Economic Espionage Act focuses on the theft of trade secrets. None of these acts is tailored to the unique requirements of securing credit card transactions in the way that PCI DSS is.
