DTBI318
(in versions v1 r16 through v1 r14)
Title
Internet Explorer must be set to disallow users to add/delete sites. (Cat II impact)
Discussion
This setting prevents users from adding sites to various security zones. Users should not be able to add sites to different zones, as this could allow them to bypass security controls of the system. If you do not configure this policy setting, users will be able to add or remove sites from the Trusted Sites and Restricted Sites zones at will and change settings in the Local Intranet zone. This configuration could allow sites that host malicious mobile code to be added to these zones, and users could execute the code.
