Which of the following is a standard security protocol used for secure communication over the internet?1 pointFTPSMTPSSL/TLSHTTP

To determine the standard security protocol used for secure communication over the internet, we need to analyze the options provided.

1. FTP (File Transfer Protocol): FTP is primarily used for transferring files between a client and a server. However, it does not provide encryption for data transmission, so it is not a standard security protocol for secure communication over the internet.

2. SMTP (Simple Mail Transfer Protocol): SMTP is a protocol used for sending and receiving email messages. Similar to FTP, it does not provide encryption for data transmission, so it is not a standard security protocol for secure communication over the internet.

3. SSL/TLS (Secure Sockets Layer/Transport Layer Security): SSL/TLS is a widely used security protocol that provides encryption and authentication for secure communication over the internet. It ensures that data transmitted between a client and a server is encrypted and cannot be intercepted by unauthorized parties. SSL/TLS is commonly used for secure websites (HTTPS) and other secure communication channels.

4. HTTP (Hypertext Transfer Protocol): HTTP is a protocol used for transmitting data over the internet. However, it does not provide encryption for data transmission, so it is not a standard security protocol for secure communication over the internet.

Based on the options provided, the standard security protocol used for secure communication over the internet is SSL/TLS.
