Which types of servers commonly store card verification value or code data?

The correct answer indicates that all the mentioned types of servers can potentially store card verification value (CVV) or code data. This reflects a significant aspect of the Payment Card Industry Data Security Standard (PCI DSS) guidelines, which emphasize the need for stringent controls around the storage and handling of sensitive cardholder data, including CVV codes.

Authorization servers are specifically designed to handle and process payment transactions, often interacting directly with the card networks and merchant systems. Because they play a crucial role in transaction approval, they may temporarily store CVV data during the transaction process, making them a relevant point of concern for security measures.

Web servers, which host online payment gateways and e-commerce sites, can also process and store CVV data if not properly configured or if best practices around PCI compliance are not followed. This can occur in scenarios where developers do not adhere to the standard methodologies for handling sensitive information, leading to potential data breaches.

Kiosks, often used for self-service transactions in various environments, may also capture CVV data. If these kiosks are designed for processing credit card transactions, they will have components that handle sensitive data, including CVV, depending on the implementation.

Recognizing that all of these servers interact with sensitive cardholder information highlights the
