PCI DSS Overview

  • Definition: PCI SSC stands for Payment Card Industry Security Standards Council, established by major payment brands (Visa, Discover, Mastercard, JCB, American Express) for standardized security requirements.
  • Purpose:
    • Consistency in security standards across different payment systems.
    • Collaboration across the industry to enhance trust and address emerging threats.
  • Strategic Framework:
    • Increase industry participation.
    • Evolve security standards.
    • Secure emerging payment channels.
    • Enhance standards alignment.

PCI DSS Compliance

  • Requirements:
    • 6 Goals and 12 requirements applicable to entities storing, processing, or transmitting cardholder data.
    • Account data includes cardholder data and sensitive authentication data.

PCI DSS Goals

  1. Build and Maintain a Secure Network and Systems: Implement security measures like firewalls.
  2. Protect Cardholder Data: Safeguard data at rest and in motion.
  3. Maintain Vulnerability Management Program: Conduct vulnerability scans and secure application development.
  4. Implement Strong Access Control Measures: Ensure access control on a need-to-know basis.
  5. Regularly Monitor and Test Networks: Audit logs and pen testing.
  6. Maintain an Information Security Policy: Establish policies to support implementation of security measures.

Compliance Process

  • Phases: Assess, Repair, and Report.
  • Key Activities: Risk assessment, Gap analysis, Remediation, Compliance validation.

Training and Classification

  • Importance of training in PCI DSS standards.
  • Roles:
    • Merchants: Organizations accepting payments.
    • Service Providers: Entities supporting payment processing.
  • Levels: Merchants (1-4), Service Providers (1-2).

Storage and Data Handling

  • Sensitive Authentication Data: CVV2, PINs cannot be stored post-authorization.
  • Cardholder Data: PAN must be unreadable.
    • Methods: Truncation, Encryption, Hashing, Tokenization.

Version Comparison

  • 3.2.1 vs 4.0:
    • 4.0 builds on 3.2.1, with additional requirements and flexibility.
    • 53 new requirements plus 11 for service providers.
    • 4.0 effective from 2025.

Future Trends and AI

  • AI Applications:
    • Security threat detection and response.
    • Fraud detection and prevention.
    • Data protection and encryption.
    • Automation of compliance tasks.
  • Caution: AI must be part of a comprehensive security strategy with human oversight.

Conclusion
