PCI DSS Payment

PCI DSS (Payment Card Industry Data Security Standard) is a security framework mandated by Visa, Mastercard, and other card networks to protect cardholder data. Any company handling credit cards—payment processors, e-commerce platforms, SaaS with subscriptions—must comply. PCI DSS has 12 core requirements: (1) Install firewall. (2) No hardcoded passwords. (3) Encrypt data in transit and at rest. (4) Maintain access logs. (5) Protect against malware. (6) Keep systems patched. (7) Restrict access to card data. (8) Track and monitor all access. (9) Physical security. (10) Incident response plan. (11) Regular vulnerability scanning. (12) Security policy documentation.
