What protocol is commonly used for secure web communications?

• A. FTP
• B. HTTP
• C. HTTPS
• D. SMTP

Answer: (C)

HTTPS, which stands for Hypertext Transfer Protocol Secure, is the protocol commonly used for secure web communications. It provides a secure channel over a computer network by using encryption, typically through the implementation of SSL/TLS (Secure Sockets Layer/Transport Layer Security). When a user visits a website that uses HTTPS, their data is encrypted, which helps to protect sensitive information such as login credentials, credit card numbers, and personal data from being intercepted by malicious actors. This added layer of security is crucial, especially in scenarios where users are transmitting sensitive information over the internet. Unlike HTTP, which is not encrypted and could expose data to eavesdropping, HTTPS ensures that the communication between the user's web browser and the server is secure. This is why you often see a padlock icon in the web address bar when you visit an HTTPS-secured site.
