PCI DSS Scoping Optimization Project

Newsman Retail CorporationRetail5 months

Project Objective

Conduct comprehensive PCI DSS scoping exercise to accurately identify systems in scope for PCI DSS, implement network segmentation, and reduce the compliance footprint while maintaining security.

Methodologies & Approach
  • Detailed data flow mapping of all cardholder data flows
  • Network architecture review and documentation
  • System inventory and classification based on PCI DSS scoping guidance
  • Network segmentation design and implementation
  • Segmentation testing methodology development
  • Implementation of network access controls between segments
  • Development of scope management procedures
Tools & Technologies

Network access control solutions
Outcomes & Results
  • Reduced PCI DSS scope by 65% through effective network segmentation
  • Decreased the number of in-scope systems from 450 to 158
  • Implemented clear network segmentation with strict access controls
  • Developed comprehensive data flow documentation for all cardholder data
  • Created automated segmentation testing process to validate controls
  • Reduced annual compliance assessment costs by approximately $175,000
  • Decreased remediation effort by focusing security controls on truly in-scope systems
  • Established sustainable scope management process integrated with change management
Key Insights & Lessons Learned
  • Early stakeholder engagement is critical for successful PCI DSS initiatives to ensure buy-in and alignment with business objectives.
  • A risk-based approach to implementation allows for more efficient resource allocation and prioritization of activities.
  • Clear documentation and evidence collection processes are essential for successful PCI DSS assessments.
  • Integration with existing business processes is essential for sustainable compliance programs.
  • Continuous monitoring and testing are key to maintaining compliance between formal assessments.
