The PCI Security Standards Council (PCI SSC) is enhancing its efforts to strengthen security in e-commerce environments. To assist organisations in navigating the requirements set out in PCI DSS v4.0.1, the PCI SSC will soon release guidance focused on e-commerce security, specifically addressing Requirements 6.4.3 and 11.6.1 for payment page security, and Requirement 12.3.1 for a Targeted Risk Analysis to support Requirement 11.6.1.
This guidance, expected in early 2025, will offer valuable insights for online merchants, service providers, and data protection professionals, helping them prepare for the new security measures set to become mandatory by March 31, 2025.
In this blog, we will explore the significance of these upcoming changes, their potential impact on e-commerce security, and how data protection experts can support organisations in complying with these standards to maintain a secure online payment environment.
PCI DSS v4.0.1 introduces several "future-dated" requirements for online merchants, with Requirements 6.4.3 and 11.6.1 being particularly significant for e-commerce due to their focus on preventing and detecting tampering on payment pages.
These requirements address vulnerabilities like cross-site scripting (XSS) and Magecart attacks, which target payment pages to capture sensitive payment information. As e-commerce breaches increase, these controls offer essential protection against such attacks.
With the increase in e-commerce security breaches, safeguarding online payment environments has never been more crucial. Cybercriminals are increasingly targeting payment pages, injecting malicious code to steal sensitive information like credit card details directly from users. Requirements 6.4.3 and 11.6.1 are designed to make such tampering more difficult. Organisations must closely monitor every element running on payment pages and swiftly detect any unauthorised changes.
By implementing these controls, businesses can:
PCI DSS v4.0.1 introduces essential updates to address growing threats and protect payment data.
