    • Do not use vendor-supplied defaults for system passwords and other security parameters
  • Protect Cardholder Data
    • Protect stored cardholder data
    • Encrypt transmission of cardholder data across open, public networks
  • Maintain a Vulnerability Management Program
    • Use and regularly update anti-virus software
    • Develop and maintain secure systems and applications
  • 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
