Procedures for Setting the Security Level to High for Specific Web Sites
The procedures that follow provide information about how to set the security level for a particular Web site to High, which prevents actions such as the running of scripts and the downloading of files from the site. For information about planning a configuration for your organization to control whether Internet Explorer allows downloads or allows plug-ins, ActiveX controls, or scripts to be run, see Examples of the Security-Related Features Offered in Internet Explorer 6 and Learning About Security and Privacy Settings in Internet Explorer 6, earlier in this section.
To Configure a Specific Computer with a Security Level of High for Specific Sites
1. On the computer on which you want to configure a security level of High for specific sites, in Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
2. Select Restricted sites.
3. Under Security level for this zone, make sure the slider for the security level is set to High. If the security level for the zone is Custom, click Default Level and make sure the slider for the security level is set to High.
You can view the individual settings that make up High security by clicking Custom Level. For example, you can click Custom Level and then scroll down to confirm that for High security, the settings for active scripting and for file download are both Disable. After viewing the settings, click Cancel.
4. With Restricted sites still selected, click Sites.
