Which security standard must a company comply with to accept credit card payments on its e-commerce platform?

The requirement for a company to comply with a specific security standard to accept credit card payments on its e-commerce platform is governed by the Payment Card Industry Data Security Standard (PCI DSS). This standard is designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment. Compliance with PCI DSS helps protect sensitive cardholder data from fraud and security breaches, and it includes a series of requirements covering various aspects of security management, including security policy, data protection, access control, and regular monitoring and testing of networks.

The other standards mentioned, while relevant to different aspects of information security and business continuity, do not specifically apply to the processing of credit card information in the same way that PCI DSS does. For instance, ISO 22301 focuses on business continuity management, ensuring that organizations can continue operating through disruptions, while ISO 27001 pertains to information security management systems and establishing, implementing, maintaining, and continually improving an organization's information security. The NIST Cybersecurity Framework (CSF) provides guidelines for managing cybersecurity risk but is not a standard specifically for credit card processing. Thus, the correct answer reflects the unique role PCI DSS plays in protecting payment card transactions.
