PCI requirement 12: Support Security with Policies

Introduction

PCI DSS Requirement 12 serves as the foundational pillar that transforms technical security controls into a comprehensive, organization-wide security program. While the previous eleven requirements focus on specific technical and operational controls, Requirement 12 establishes the governance framework that ensures these controls are properly maintained, monitored, and continuously improved.

This requirement mandates that organizations develop, implement, and maintain robust information security policies that cover all aspects of cardholder data protection. It recognizes that even the most sophisticated technical controls can fail without proper organizational support, clear accountability, and ongoing management commitment.

Within the PCI DSS framework, Requirement 12 acts as the orchestrating force that brings together all other requirements into a cohesive security program. It ensures that security isn’t just a collection of technical configurations, but rather a mature, business-integrated approach to protecting sensitive payment card data. This requirement addresses the human element of security, acknowledging that people, processes, and technology must work in harmony to create effective data protection.
