New PCI DSS Standard Requires WAFs for All Payment Systems by March 2025

Effective March 31, 2025, the Payment Card Industry Data Security Standard (PCI DSS) version 4.0 will require the use of Web Application Firewalls (WAFs) for all organizations handling credit card transactions. This update makes WAFs mandatory to enhance protection against web-based attacks targeting payment applications. WAFs help filter and monitor HTTP/HTTPS traffic, preventing attacks such as SQL injection and cross-site scripting. By implementing WAFs, organizations can proactively detect and block malicious traffic, ensuring the integrity of payment systems. The transition to PCI DSS 4.0 reflects the evolving cybersecurity threat landscape, and organizations are urged to update their security infrastructure to meet the new requirements and avoid penalties.

OWASP SAMM Skills Framework Enhances Software Security Roles

The OWASP SAMM Skills Framework, introduced on February 9, 2025, is a new initiative donated by Siemens to enhance software security practices within organizations. This framework assigns specific responsibilities to SAMM (Software Assurance Maturity Model) streams, clarifying which roles are involved in advancing each stream. It provides guidance on the necessary skills and training for each role, aligning SAMM-related activities with appropriate stakeholders and their required competencies. This alignment helps organizations identify the right personnel and visualize shared responsibilities, ensuring a structured approach to secure product development. Implementing the OWASP SAMM Skills Framework involves several key steps. Organizations must first map responsibilities to roles, ensuring each task is assigned to the right individual. Next, they must evaluate and align stakeholders with specific SAMM streams, validating that those assigned understand and accept their roles in advanci...
