What protocol would a systems administrator implement to ensure all web traffic is secure?

• A. TLS
• B. SSH
• C. SSL
• D. HTTP

Answer: (C)

The correct choice for ensuring all web traffic is secure is the protocol known as SSL, which stands for Secure Sockets Layer. SSL functions to encrypt the data transmitted between a client and a server, making it difficult for unauthorized users to intercept or tamper with the information being sent. This encryption is essential for protecting sensitive data, such as login credentials, credit card information, and personal details, while it's being transmitted over the internet. It's important to note that while SSL has been widely used historically, it has largely been replaced by TLS (Transport Layer Security), which is a more secure and updated protocol. However, many still refer to the technology in general or legacy systems as SSL, leading to a common understanding of the concept of secure web traffic. Understanding the context of other options helps clarify the choice of SSL. SSH (Secure Shell) is primarily used for secure access to remote servers and for secure file transfers, but it is not specifically designed for securing web traffic. HTTP (Hypertext Transfer Protocol) is the standard protocol for transferring data on the web but does not incorporate any security features, making it unsuitable for transmitting sensitive information without additional security measures.
