Which protocol is commonly used for secure data transmission over the Internet?

The protocol commonly used for secure data transmission over the Internet is HTTPS. This protocol is an extension of HTTP (Hypertext Transfer Protocol) and includes an additional layer of security by incorporating SSL (Secure Sockets Layer) or TLS (Transport Layer Security). This ensures that the data exchanged between web browsers and servers is encrypted, making it much harder for unauthorized parties to intercept or tamper with the information.

Using HTTPS provides the necessary security measures for sensitive transactions, such as online banking, shopping, and personal information submission. Many websites today implement HTTPS as a standard to protect user data and enhance trustworthiness. This level of security is essential for protecting the integrity and confidentiality of the data being transmitted.

Other options do not provide the same level of security for internet data transmission as HTTPS does.
