Least Privilege in Payment Processing

Least Privilege is a security principle that restricts access to only what is necessary for a user, system, or application to perform its job. In payment processing, this limits the risk of unauthorized transactions, fraud, and data breaches by ensuring employees and systems have minimal access to sensitive financial information.

Why It’s Important:

Applying Least Privilege helps businesses protect customer payment data, prevent internal and external threats, and comply with security regulations like PCI DSS (Payment Card Industry Data Security Standard). By controlling access, companies reduce vulnerabilities and improve overall cyber security.
