Security zones (Adding or Removing websites)

Internet Explorer assigns all websites to one of four security zones; Internet, Local intranet, Trusted sites or Restricted sites. The zone to which a website is assigned specifies the security settings that are used for that site. You can choose which websites to assign to the Intranet, Trusted, or Restricted zones. By adding a website to a specific zone, you can control the level of security used on that site. For example, if you have a list of websites that you visit and you completely trust those sites, add those sites to the trusted zone.

• Click to open Internet Explorer. 
• Navigate to the website that you want to add to a specific security zone.

Note: If the site is not a secure site (HTTPS), clear the Require server verification (https:) for all sites in this zone check box.
