What protocol is used for securing connections to Oracle Autonomous Database?

The protocol used for securing connections to Oracle Autonomous Database is SSL/TLS. SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols designed to provide secure communication over a computer network. When connecting to Oracle Autonomous Database, SSL/TLS ensures that the data exchanged between the client and the database is encrypted, safeguarding it from eavesdropping and tampering.

This security feature is crucial for database connections, as it protects sensitive information, such as user credentials and data queries, from being intercepted during transmission. The use of SSL/TLS is typical in various database systems, including Oracle Autonomous Database, as it meets the industry standards for data protection and security compliance.

Other options such as HTTPS, while also a protocol that secures data over the internet, specifically applies to web communication. FTP (File Transfer Protocol) is not secure and transmits data in plaintext, making it unsuitable for database connections. SSH (Secure Shell) is primarily used for secure shell access and remote command execution, making it less relevant for direct database connections. Therefore, SSL/TLS is the appropriate choice for the secure transmission of data to and from Oracle Autonomous Database.
