PCI DSS
PCI DSS (Payment Card Industry Data Security Standard) is a set of security standards designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment. It was established by major credit card brands (Visa, MasterCard, American Express, Discover, and JCB) to protect cardholder data and reduce credit card fraud. Compliance involves implementing controls around network security, data protection, vulnerability management, access control, and monitoring.
Developers should learn and apply PCI DSS when building or maintaining systems that handle payment card data, such as e-commerce platforms, payment gateways, or financial applications, to ensure legal compliance and protect sensitive information. It is crucial for reducing security risks, avoiding hefty fines from non-compliance, and maintaining customer trust in payment processing systems.
