Which method best describes how to ensure a secure data transfer process?

Transport Layer Encryption is an essential method for ensuring a secure data transfer process. This technique involves encrypting the data that is transmitted over a network, ensuring that even if someone intercepts the data, they cannot read it without the appropriate decryption keys. This layer of security is crucial in protecting sensitive information as it travels between systems, such as in a web application, banking transactions, or any scenario where data is exchanged over the internet.

By using transport layer encryption protocols—such as TLS (Transport Layer Security)—organizations can provide confidentiality and integrity for the data being conveyed. This means not only is the data protected from eavesdroppers, but it also ensures that the data has not been altered during transit.

While file encryption, tokenization, and data masking address security in different contexts, they do not specifically ensure the security of data in transit as effectively as transport layer encryption does. File encryption secures data at rest and does not address data being sent over the network. Tokenization replaces sensitive information with tokens but may still require secure transport methods. Data masking is used to obfuscate sensitive data in non-production environments but does not encrypt data in transit. Thus, transport layer encryption remains the most suitable method for ensuring secure data transfer.
