Demystifying PCI Compliance: Everything you need to Know | Best Practices for Securing Payment Card Data.

Posted by:


PCI Compliance, short for Payment Card Industry Data Security Standard (PCI DSS), is a set of security standards designed to ensure the secure handling of credit card information during payment card transactions. These standards were established to protect cardholder data and reduce the risk of data breaches and financial fraud.

The PCI DSS consists of a series of security requirements and best practices that organizations that handle payment card data must follow. It applies to all entities involved in credit card transactions, including businesses, payment processors, financial institutions, and service providers.

The PCI DSS framework includes six primary objectives, each with specific requirements:

  1. Build and Maintain a Secure Network and Systems:
    • Install and maintain a firewall configuration to protect cardholder data.
    • Do not use vendor-supplied default settings for system passwords and other security parameters.
  2. Protect Cardholder Data:
    • Protect stored cardholder data.
    • Encrypt transmission of cardholder data across open, public networks.
  3. Maintain a Vulnerability Management Program:
    • Use and regularly update antivirus software.
    • Develop and maintain secure systems and applications.
  4. Implement Strong Access Control Measures:
    • Restrict access to cardholder data by business need-to-know.
    • Assign a unique ID to each person with computer access.
    • Restrict physical access to cardholder data.
  5. Regularly Monitor and Test Networks:
    • Track and monitor all access to network resources and cardholder data.
