Requirement 7 - Restrict Access to System Components by Business Need to Know

Requirement 7 of PCI DSS 4.0 mandates that organizations limit access to cardholder-data environments and related system components only to individuals whose job responsibilities require it. Access rights must be defined, documented, and reviewed regularly to ensure they align with the principle of least privilege and are revoked promptly when no longer needed. This helps prevent unauthorized exposure of sensitive payment information.
