What encryption method is used to secure data transmission between servers?

The selection of the Secure Sockets Layer (SSL) as the encryption method for securing data transmission between servers is correct because SSL is designed to provide a secure communication channel over a computer network. It accomplishes this by encrypting the data that is transmitted, ensuring that any sensitive information exchanged between servers remains confidential and is protected from eavesdropping or tampering.

SSL operates at the transport layer between the transport and application layers of the OSI model, allowing it to secure any protocol that operates above it, such as HTTP (creating HTTPS). This widespread adoption and its foundation for secure internet communication protocols make SSL a crucial component for securing data in transit.

Moreover, while Transport Layer Security (TLS), which is the successor to SSL, provides even stronger security mechanisms, the context of the question suggests that SSL would be the reference point for secure data transmission. This highlights the importance of these protocols in maintaining data security during transmission between servers.

Other methods like whole-instance encryption focus on encrypting entire instances rather than securing data during transmission. FIPS-approved encryption pertains to specific standards for encryption algorithms, but it does not directly address transmission security. As for the term "transport layer security," it's technically accurate but commonly referenced as TLS rather than SSL in current
