PCI DSS (Payment Card Industry Data Security Standard) Requirements
PCI DSS 4.0 is the latest version of the Payment Card Industry Data Security Standard, which outlines 12 requirements for companies that handle payment card data.
Per Control Case, these requirements include:
- Install and maintain a firewall configuration to protect cardholder data
- Do not use vendor-supplied defaults for system passwords and other security parameters
- Protect stored cardholder data
- Encrypt transmission of cardholder data across open, public networks
- Use and regularly update anti-virus software or programs
- Develop and maintain secure systems and applications
- Restrict access to cardholder data by business need to know
- Assign a unique ID to each person with computer access
- Restrict physical access to cardholder data
- Track and monitor all access to network resources and cardholder data
- Regularly test security systems and processes
- Maintain a policy that addresses information security for all personnel
By following these requirements, businesses can protect their customers’ financial data and build trust between themselves and their customers.
PCI DSS 4.0 Changes and Updates
In addition to the new requirements mentioned earlier, PCI DSS 4.0 introduces several key changes that focus on improving application security, testing, and documentation. These changes include:
- Stronger focus on application security, with regular testing and documentation required.
- Greater emphasis on vulnerability testing and documentation of the results.
- More comprehensive documentation of security policies and procedures.
- Stronger focus on risk assessment and management.
- Multi-factor authentication for remote access to cardholder data.
- Stricter controls for third-party service providers updated guidance on encryption, vulnerability management, and incident response.
These changes reflect a more proactive approach to security, which is necessary for businesses to maintain customer trust and protect cardholder data. While these changes may require more work for businesses, the benefits of improved security and customer trust are well worth the effort.
Risks of Non-Compliance
Non-compliance with PCI DSS 4.0 can have serious consequences for businesses, including:
- Fines: The payment card brands (like Visa, Mastercard) can impose fines on non-compliant businesses, which can be pretty hefty.
- Loss of Merchant Status: A business may lose its merchant status, which means it can no longer accept payment cards. This can be a big blow to their revenue.
- Reputational Damage: Non-compliance can damage a business’s reputation and trust with customers, which can lead to a loss of customers.
- Data Breaches: Non-compliance can also increase the risk of data breaches, which can be costly to remediate and can lead to more fines and legal action.
Overall, PCI DSS 4.0 represents a major step forward in the protection of payment card data and is essential for businesses that handle such data to understand and comply with.
