Which encryption technologies are used in PCI DSS?

The correct choice highlights the use of SSL/TLS for securing data in transit and AES for encrypting data at rest, which aligns with industry best practices and the requirements established by PCI DSS (Payment Card Industry Data Security Standard).

SSL/TLS protocols are critical for protecting sensitive data during transmission over networks, ensuring that information like credit card data is encrypted while moving between the customer and the merchant, substantially reducing the risk of interception by malicious parties.

Similarly, AES (Advanced Encryption Standard) is widely recognized as a strong encryption method for data at rest. This means that data stored in databases, on servers, or on other storage media is encrypted, making it much harder for unauthorized users to access sensitive information in the event of a data breach.

This combination of encryption technologies addresses key aspects of data protection required by PCI DSS, emphasizing the importance of both securing data in transit and ensuring the security of stored data.
