PCI DSS Requirement 7: Restrict Cardholder Data Access
Blog post from Basis Theory
PCI DSS Requirement 7 focuses on protecting cardholder data by enforcing least-privilege, need-to-know access to systems and data. It requires organizations to document and maintain access-control policies, define staff responsibilities, assign permissions according to job functions, obtain authorized approval for privileges, and review user and third-party access at least every six months. System and application accounts must receive only the access needed for operation, while direct access to stored cardholder-data repositories is generally limited to responsible administrators. Access-control systems should enforce role-based permissions across all components and default to denying access unless it is explicitly granted. The passage also presents Basis Theory as a PCI Level 1-compliant provider that offers an assessed cardholder data environment and tokenization tools intended to help businesses secure payment data while reducing the scope, cost, and operational burden of PCI DSS compliance.
