Which practice helps protect data in transit by encrypting communications between a user and websites?

• A. Use HTTPS for all sites.
• B. Disable TLS and use HTTP.
• C. Rely on VPNs alone.
• D. Share passwords over chat.

Answer: (A)

Protecting data in transit means making sure information moving between your device and a website is unreadable to anyone who might intercept it. The way to do this on the web is by using HTTPS, which applies TLS to HTTP. This encrypts the traffic, so login details, passwords, and personal data aren’t sent in plain text. It also authenticates the site so you’re talking to the real website and not an imposter, and it preserves data integrity so messages aren’t tampered with along the way. Using HTTPS for every site is the best practice because it provides end-to-end encryption for web communications. In contrast, plain HTTP transmits data in plaintext, leaving it exposed. Relying solely on a VPN can add a layer of encryption to your traffic to the VPN server, but it doesn’t guarantee that the data remains protected all the way to every website you visit, and it depends on trusting the VPN provider. Sharing passwords over chat is insecure because chats can be intercepted or accessed by others.
