Which protocol is used for secure communication over the internet?

• A. FTP (File Transfer Protocol)
• B. SMTP (Simple Mail Transfer Protocol)
• C. HTTPS (Hypertext Transfer Protocol Secure)
• D. HTTP (Hypertext Transfer Protocol)

Answer: (C)

HTTPS, or Hypertext Transfer Protocol Secure, is the protocol designed specifically for secure communication over the internet. It is built on top of HTTP (Hypertext Transfer Protocol) but adds a layer of security by using encryption protocols like TLS (Transport Layer Security) or SSL (Secure Sockets Layer). This ensures that the data transferred between a user's web browser and the website is encrypted, helping to protect sensitive information such as login credentials, credit card numbers, and personal details from being intercepted by malicious actors. In contrast, the other protocols mentioned do not inherently provide the same level of security. For instance, FTP is used for transferring files over the internet but does not include encryption, making data vulnerable during transmission. SMTP is designed for sending and receiving email, but like FTP, it lacks the necessary security measures unless additional protocols such as SMTPS are used. Although HTTP facilitates browsing the web, it does not encrypt data, exposing it to potential eavesdropping or interception. Thus, HTTPS is the correct choice when it comes to protocols designed for secure communication on the internet.
