this zone slider on the Security tab in the Internet Options dialog box. If this policy setting
is disabled or not configured, users will be able to change the settings for security zones. It
prevents users from changing security zone policy settings that are established by the
administrator. Note If you enable the Disable the Security page setting (located in \User
Configuration\ Administrative Templates\Windows Components\Internet
Explorer\Internet Control Panel) the Security tab is removed from Internet Explorer in
Control Panel and the Disable setting takes precedence over this Security Zones- setting.

Users who change their Internet Explorer security settings could enable the execution of
dangerous types of code from the Internet and Web sites that were listed in the Restricted
Sites zone in the browser.
