Which protocol is used by OCI for securing data in transit?

The use of SSL/TLS (Secure Sockets Layer/Transport Layer Security) is essential for securing data in transit within Oracle Cloud Infrastructure (OCI). This protocol provides a robust layer of encryption and security for data being transmitted over networks, ensuring that sensitive information remains confidential and protected from interception.

SSL/TLS establishes a secure connection between clients and servers by encrypting the data exchanged between them, which prevents unauthorized access and eavesdropping. This is particularly crucial in cloud environments, where data integrity and confidentiality are critical aspects of service delivery and compliance.

Other protocols mentioned, such as HTTP, FTP, and SSH, have different roles in networking. While HTTP is the foundation of data communication on the web, it does not provide encryption, making it unsuitable for securing data in transit. FTP (File Transfer Protocol) is primarily used for transferring files but also lacks security measures for protecting data during transmission. SSH (Secure Shell) is a protocol used for secure remote login and command execution but is not specifically used for securing general data in transit in the same way SSL/TLS does.

Thus, SSL/TLS stands out as the correct choice because it directly addresses the need to protect data during transmission across networks in the context of OCI.
