Title

Allow binary and script behaviors must be disallowed (Restricted Sites zone). (Cat II impact)

Discussion

This policy setting allows you to manage dynamic binary and script behaviors of components that encapsulate specific functionality for HTML elements, to which they were attached. If you enable this policy setting, binary and script behaviors are available. If you select "Administrator approved" in the drop-down box, only the behaviors listed in the Admin-approved Behaviors under Binary Behaviors Security Restriction policy are available. If you disable this policy setting, binary and script behaviors are not available unless applications have implemented a custom security manager. If you do not configure this policy setting, binary and script behaviors are available.
