Which security method is essential to protect customer credit information during data transport?

1. HDMI encryption

2. Application level encryption

3. Using basic password protection

4. Disabling firewalls during transport

The correct answer is: Application level encryption

Application level encryption is crucial for protecting customer credit information during data transport because it ensures that the data is encrypted at its source and remains secure while being transmitted across networks. By encrypting the data at the application layer, sensitive information such as credit card details is rendered unreadable to unauthorized parties, ensuring confidentiality and data integrity during transmission. This approach is particularly effective in safeguarding information as it travels over potentially insecure networks, such as the internet. It provides an additional layer of security beyond network-level measures, protecting against various threats including interception by malicious actors. Other methods listed, such as HDMI encryption, while relevant for certain types of media, do not apply to the transport of credit information. Basic password protection is often inadequate as a standalone measure for protecting sensitive data during transport. Disabling firewalls poses significant security risks and is counterproductive, as it leaves the system vulnerable to attacks during data transmission. Therefore, application level encryption stands out as the most effective method for securing credit information in transit.
