PCI DSS Details
What It Is
PCI DSS (Payment Card Industry Data Security Standard) is a global industry framework establishing technical and operational requirements to protect cardholder data (CHD) and sensitive authentication data (SAD). Managed by the PCI Security Standards Council (PCI SSC), it applies a control-based approach with contractual enforcement for merchants and service providers handling payment cards.
Key Components
- 12 core requirements grouped into 6 control objectives (e.g., secure networks, vulnerability management, access controls).
- Over 300 sub-requirements and testing procedures.
- **Levels-based compliance modelSAQ for smaller entities, ROC by QSAs for high-volume.
- Focus on CDE scoping, segmentation, and v4.0 customized approaches.
Why Organizations Use It
- Contractual obligation from card brands to avoid fines, processing bans.
- Reduces breach costs ($37/record avg.), builds customer trust.
- Enhances risk management, aligns with GDPR.
Implementation Overview
Phased approach: scope CDE, gap analysis, remediate controls, validate via scans/audits. Applies to all card-handling entities globally; ongoing via quarterly ASV scans, annual pentests. Costs $5K-$200K+; 6-12 months typical.
ISO 17025 Details
What It Is
ISO/IEC 17025:2017 is the international standard titled General requirements for the competence of testing and calibration laboratories. It is an accreditation framework emphasizing competence, impartiality, and consistent operation. The standard adopts a risk-based, performance-oriented approach, linking management system controls to technical validity of results.
Key Components
- Eight clauses: general (impartiality/confidentiality), structural, resource requirements (personnel, facilities, equipment, traceability), process requirements (methods, sampling, uncertainty, reporting), and management systems.
- Built on risk-based thinking, metrological traceability, and method validation.
- Option A/B model for management systems; leads to scope-specific accreditation by ILAC bodies.
Why Organizations Use It
- Enables global acceptance of results, market access in regulated sectors.
- Meets supplier/regulatory demands, reduces rejection risks.
- Enhances operational efficiency, data reliability, stakeholder trust.
- Provides competitive differentiation via proven technical competence.
Implementation Overview
- Phased PDCA: gap analysis, documentation, training, validation, audits.
- Applies to labs worldwide, all sizes; requires proficiency testing, witnessed assessments for accreditation.
