What is Secure Sockets Layer (SSL)?
Secure Sockets Layer (SSL) is an internet security protocol for establishing an encrypted connection between a web server and a browser.
Sites using secure sockets layer technology begin with https:// rather than the http:// used by unsecured sites. The sites will also display a padlock icon when you view the site’s information, as shown below.
Secure Sockets Layer helps keep data transmitted between a server and browser private. This protects sensitive information such as login credentials, credit card details, and other personal data from being intercepted or tampered with by criminals, hackers, and other unauthorized parties.
