PCI DSS Details
What It Is
PCI DSS (Payment Card Industry Data Security Standard) is a contractual security framework for protecting cardholder data (CHD). Developed by PCI SSC, it mandates technical/operational controls for entities storing, processing, or transmitting CHD/SAD. Control-based approach with scoping via Cardholder Data Environment (CDE).
Key Components
- 12 requirements under 6 objectives: secure networks, data protection, vulnerability management, access controls, monitoring, policies.
- 300+ sub-requirements; v4.0 adds customized approaches.
- Levels 1-4 validation: ROC/SAQ, ASV scans, pentests.
Why Organizations Use It
- Contractual mandate avoids fines, processing bans.
- Reduces breach costs ($37/record avg.), builds trust.
- Enhances risk management, fraud prevention.
- Competitive edge for merchants/service providers.
Implementation Overview
- Assess-Repair-Report cycle: scope CDE, gap analysis, remediate.
- Phased: discovery, controls, validation.
- All card-handling orgs; QSA/ASV for high-volume. (178 words)
ISO 27032 Details
What It Is
ISO/IEC 27032:2023, titled Cybersecurity – Guidelines for Internet Security, is an international guidance standard providing non-certifiable recommendations for securing Internet-facing operations. Its primary purpose is to enhance cybersecurity through multi-stakeholder collaboration, addressing risks in cyberspace ecosystems. It adopts a risk-based approach, linking Internet security to information, network security, and critical infrastructure protection (CIIP).
Key Components
- Core pillars: stakeholder roles, risk assessment, incident management, controls across preventive, detective, and corrective domains.
- Around 14 thematic areas in prior edition, consolidated for Internet focus; Annex A maps to ISO/IEC 27002 controls.
- Built on collaboration, trust, and PDCA cycle; no fixed control count, emphasizes integration over standalone use.
- Compliance via voluntary adoption into ISMS like ISO/IEC 27001.
Why Organizations Use It
Drives risk reduction, regulatory alignment (e.g., NIS2), resilience, and efficiency. Builds stakeholder trust, enables market access, cuts breach costs via faster response.
Implementation Overview
Phased approach: scoping, gap analysis, risk treatment, controls deployment, monitoring. Suits all sizes/industries with online presence; no certification, focuses on audits and continuous improvement. (178 words)
