This book provides an essential resource for anyone involved in managing or ensuring PCI DSS compliance. It begins by introducing the Payment Card Industry Data Security Standard (PCI DSS), explaining its importance, and the regulatory framework that governs it. Readers will understand how to assess their organization's compliance status and the vital steps to avoid data breaches. The book offers a comprehensive exploration of compliance programs and how organizations can design their own effective strategies. The text then dives into the specifics of PCI DSS, focusing on its core components and requirements. Key chapters describe how to comply with and maintain compliance, as well as how to use tools like the PCI self-assessment questionnaire (SAQ). Real-world case studies of cardholder data breaches highlight the consequences of non-compliance. Readers will also learn about the integration of PCI DSS with other standards like ISO/IEC 27001. Throughout, this guide emphasizes practical advice for implementing key security frameworks such as the Software Security Framework (SSF) and Point-to-Point Encryption (P2PE). By the end of the book, readers will have a clear roadmap to not only meet but sustain PCI DSS compliance and strengthen their organization's data security practices.
