back to topCredit/Debit Card Security (PCI DSS)

The Payment Card Industry Data Security Standard (PCI DSS) was created by the major credit card companies to ensure the adoption of consistent security measures by all merchants. Organisations handling large volumes of transactions must have their compliance assessed by an independent assessor known as a Qualified Security Assessor (QSA), while companies handling smaller volumes have the option of self-certification via a Self-Assessment Questionnaire (SAQ).

There are 12 requirements for meeting the PCI DSS, broken into 6 groups:

  • Build and Maintain a Secure Network
    • Requirement 1: Install and maintain a firewall configuration to protect cardholder data
    • Requirement 2: Do not use vendor-supplied defaults for system passwords and other security parameters
  • Protect Cardholder Data
    • Requirement 3: Protect stored cardholder data
    • Requirement 4: Encrypt transmission of cardholder data across open, public networks
  • Maintain a Vulnerability Management Program
    • Requirement 5: Use and regularly update anti-virus software
    • Requirement 6: Develop and maintain secure systems and applications
  • Implement Strong Access Control Measures
    • Requirement 7: Restrict access to cardholder data by business need-to-know
    • Requirement 8: Assign a unique ID to each person with computer access
    • Requirement 9: Restrict physical access to cardholder data
  • Regularly Monitor and Test Networks
    • Requirement 10: Track and monitor all access to network resources and cardholder data
    • Requirement 11: Regularly test security systems and processes
  • Maintain an Information Security Policy
    • Requirement 12: Maintain a policy that addresses information security
