Which protocols are commonly used to secure HTTP connections?

Hypertext Transfer Protocol (HTTP)
File Transfer Protocol (FTP)
Transport Layer Security (TLS) and Secure Sockets Layer (SSL)
Simple Mail Transfer Protocol (SMTP)

The correct answer is: Transport Layer Security (TLS) and Secure Sockets Layer (SSL)

The inclusion of Transport Layer Security (TLS) and Secure Sockets Layer (SSL) as the correct answer highlights their fundamental role in securing HTTP connections. Both TLS and SSL are cryptographic protocols designed to provide secure communication over a computer network. When utilized with HTTP, they create what is often referred to as HTTPS (HTTP Secure), which encrypts the data exchanged between client and server, ensuring privacy and security from eavesdropping, tampering, and forgery. TLS, which is the successor to SSL, provides stronger encryption and improved security features. This encryption protects sensitive information such as credit card numbers, login credentials, and personal data, making it essential for any secure web application. As a result, these protocols are vital for maintaining the confidentiality, integrity, and authenticity of communications over the internet.
