Visiting a "https" Web Site with IE
This section describes how IE (Internet Explorer) 9 shows a lock icon when you visit an 'https' Web site to provide you more security related information.
As I mentioned in the previous section, if a Web site wants to encrypt communication messages with your browser, it will enable the SSL protocol and use "https" as part of their Web address.
If you go to a Web site that provides online services, I am sure that you will see "https" in the Web address field starting on the log in page. This indicates that Web site uses SSL protocol to encrypt all information you send and receive on this server.
If you are using IE (Internet Explorer) 9, it will display an extra lock icon next to the Web address field
when you are connecting to an "https" Web site.
The picture below shows the "https" Web address and the lock icon when you use IE 9 to visit the Facebook log in page:
If you click the lock icon, IE will provide you a summary of security related information about this Web site. For https://www.facebook.com Web site, you will get something like:
VeriSign Class 3 Public Primary Certification Authority (PCA3 G1 has identified this site as: www.facebook.com This connection to the server is encrypted. View certificate
More security related information will be provided if you click the "View certificates" button. See next sections.
