Configuring the Restricted Sites Security Zone
The Restricted Sites security zone sets permissions for sites with potentially offensive or unauthorized content; and content that could potentially damage or harm computers, applications, and files on your network. By default, the security level for this zone is set to High. You can place sites in this security zone using the following series of steps:
In the Internet Properties dialog box, click the Security tab and then select Restricted Sites in the zone list.
Click Sites to define which sites are included in the Restricted Sites zone. This displays the Restricted Sites dialog box.
To add a restricted site, type its IP address in the Add This Web Site To The Zone text box, and click Add.
To remove a site, select the site in the Web Sites list box, and then click Remove.
Click OK twice to close the Restricted Sites and Security dialog boxes.
Putting a Web site's IP address into the Restricted Sites Security Zone does not limit access to it from any of the users in your organization. Rather, it acts to define a different security level for this site, ensuring that ActiveX, applets, scripts, and downloads from the sites do not harm either the computer accessing them or the network. To restrict access to specific sites, use the options available in the proxy server and firewall.
