What is the purpose of SSL/TLS in web security?

• A. Encrypt data in transit to prevent eavesdropping
• B. Increase page load speed
• C. Replace DNS
• D. Enable server-side scripting

Answer: (A)

SSL/TLS protects data as it travels between your browser and the website by encrypting that communication, so anyone listening on the network can’t read sensitive information like passwords or credit card numbers. It also helps verify the server’s identity with certificates and ensures the data isn’t altered while it’s in transit. This security of the transport layer is why you see HTTPS and the padlock icon. It doesn’t speed up page loads, replace DNS, or enable server-side scripting; those aren’t the roles of TLS.
