What is a Secure Server?
A secure server guarantees the privacy of the data you transmit over the network. Such privacy is achieved through the 128-bit SSL encryption protocol. Security is the result of communication between a browser under SSL protocol and a server with the same protocol. Any version of the Netscape Navigator browser and Microsoft Explorer supports this protocol.
How do I know a server is Secure?
Because of the full key at the bottom left of the Netscape browser, or by the padlock at the bottom right of your browser if you're using Microsoft Explorer. You can also see that the URL varies: it no longer starts with http but with https.
