Also known as: PCI DSS
An information security standard for organizations that process, store, or transmit payment card data.
DESCRIPTION
PCI DSS establishes baseline security controls to protect cardholder data. It covers network security, access control, encryption, monitoring, and vulnerability management. Merchants and service providers validate compliance via assessments or self-assessment questionnaires. Scope reduction through tokenization and segmentation is common. Noncompliance risks fines, breach costs, and reputational damage. The PCI Security Standards Council maintains the standard and related programs.
