The Payment Card Industry Data Security Standard (PCI DSS) is a vital framework for securing cardholder data and maintaining payment security. Cyber threats have become more sophisticated as technology has evolved over the years. PCI DSS has also evolved to address emerging challenges. The forthcoming PCI DSS 4.0 will bring significant changes and enhancements to the existing standards that must be in place by March 31, 2025. In this blog post, I will explain some of the fundamental changes you will need to be aware of.
- Expanded Scope and Applicability – PCI DSS 4.0 will expand its scope to encompass a broader list of controls within payment environments. It will apply not only to traditional merchants and service providers but also to newer participants in the payment ecosystem, such as e-commerce platforms, mobile payment providers, and cloud service providers. This change aims to keep pace with the evolving payment landscape.
- Passwordless Authentication – With the rise in password-related breaches, PCI DSS 4.0 will require more robust authentication controls. These controls include passwordless authentication methods, such as biometrics, multi-factor authentication (MFA), and single sign-on (SSO) solutions. Organizations must adopt these more secure authentication methods to comply with the updated standard.
- Enhanced Risk Assessment – The new version of PCI DSS will emphasize the importance of continuous risk assessment and management. Organizations must conduct more frequent and comprehensive risk assessments, considering emerging threats and vulnerabilities. This proactive approach will help identify and address security issues before they escalate or are the cause of a breach.
- Secure Software Development – PCI DSS 4.0 will require robust requirements for secure software development practices. Organizations involved in software development for payment applications must adhere to stringent security guidelines, including secure coding practices and regular code reviews.
- IoT and Connected Devices – The proliferation of Internet of Things (IoT) devices and their potential security risks have caught the PCI Security Standards Council (SSC) attention. PCI DSS 4.0 will include guidelines and requirements for securing IoT and connected devices within payment environments.
- Encryption Enhancements – Encryption has always been a cornerstone of PCI DSS. The new version will emphasize the importance of end-to-end encryption, including more stringent encryption algorithms and protocols to protect data in transit and at rest.
- Third-Party Risk Management – PCI DSS 4.0 will introduce more comprehensive requirements for managing third-party risks. Organizations will need robust processes to assess and monitor the security of their third-party service providers.
