Major Milestone in Payment Security Standards

The PCI Security Standards Council (PCI SSC) has announced the release of version 2.0 of the PCI Secure Software Standard, representing the most significant update to the standard since its initial publication in 2019. This milestone update, discussed in the Council's "Coffee with the Council" podcast series, introduces substantial changes that will impact software vendors and organizations handling payment card data.

What's New in Version 2.0

The Secure Software Standard v2.0 builds upon seven years of industry feedback and evolving threat landscapes. While specific details of the changes weren't fully outlined in the initial announcement, major revisions typically include:

• Enhanced security requirements for software development lifecycles
• Updated vulnerability management protocols
• Strengthened authentication and access control measures
• Revised testing and validation procedures
• New guidance for emerging technologies and payment methods

Organizations Affected by the Update
