How to Customize Security Settings in a Zone

For example, the Download Unsigned ActiveX Controls option is disabled by default in the Local Intranet zone (Medium security is the default setting for the Local Intranet zone). In this case, Internet Explorer may not run any ActiveX controls in your organization's intranet because most organizations do not sign ActiveX controls that are only used internally.

You an set the following security options by using the Custom setting:
