PCI DSS Compliance

Implement PCI DSS requirements for payment card security.

Requirements

requirements: 1_firewall: - Network segmentation - Firewall configuration - CDE isolation

3_protect_data: - Mask PAN display - Encrypt stored data - Key management

6_secure_systems: - Patch management - Secure development - Change control

8_access_control: - Unique IDs - MFA for remote access - Password policies

10_logging: - Audit trail - Time synchronization - Log retention (1 year)

11_testing: - Vulnerability scans - Penetration testing - IDS/IPS monitoring

Network Segmentation

Internet --> DMZ --> Firewall --> CDE | Non-CDE <-- Firewall --

Data Protection

encryption: at_rest: AES-256 in_transit: TLS 1.2+ key_storage: HSM or dedicated key vault

tokenization:

• Replace PAN with token
• Store mapping securely
• Reduce CDE scope

Best Practices

• Minimize CDE scope

• Use tokenization

• Quarterly vulnerability scans

• Annual penetration tests

• ASV scan certification
