Secure Sockets Layer (SSL) is a security protocol that creates an encrypted link between a web server and a web browser. It ensures that all transferred data remains confidential.

You've seen a lock icon next to the URL in your address bar when you go to certain sites, right? That means the site is protected by SSL.
