12.3.3 requires?

12.3.3 requires?

• A. A list of all such devices and personnel with access
• B. Acceptable network locations for the technologies
• C. A method to accurately determine owner, contact information, and purpose
• D. Explicit approval by authorized parties

Answer: (A)

The main idea here is ensuring visibility and control over who and what can reach cardholder data. PCI DSS 12.3 focuses on access control measures, and 12.3.3 specifically requires maintaining a current list of every device and every person who has access to the cardholder data environment. Having this inventory lets you enforce least-privilege access, regularly review and revoke access when roles change or people leave, and quickly identify any unauthorized devices or users that could threaten security. Without a complete inventory, you can’t reliably manage access or prove to audits that only authorized entities can reach sensitive data. The other options miss the core need of this sub-requirement. Knowing acceptable network locations for technologies, or having ownership/contact information, or requiring explicit approvals are related but not the explicit need to catalog all devices and personnel with access.
