Determines whether or not script code on HTML pages in the URL security zone is allowed to use Java applets if the properties, methods, and events of the applet are exposed to scripts. Determines if subframes are allowed to navigate across different domains. If you configure the Site to Zone Assignment List policy setting for both Computer Configuration and User Configuration, both of these lists are used. Determines if scripting of safe ActiveX Controls is allowed. Web sites that are not mapped into other zones automatically fall into this zone. This enables any processes created by Internet Explorer to be restricted by this security feature control. This policy setting defines whether a reference to an object is accessible when the user navigates within the same domain or to a new domain.
For example, if you do not configure the Open files based on content, not file extension policy setting, files are opened based on content for every zone, except the Restricted Sites zone. Internet Explorer checks to see if the Security Feature is enabled, and if it is and the Security Feature uses URL actions, it looks for the setting for the action based on the security zone of the URL. However, while these preferences are stored in the registry when policy is unset, they do not override Group Policy settings. Object safety should be overridden only if all ActiveX Controls and scripts that might interact with them on pages in the zone can be trusted not to breach security. After computer policies, the user policies are applied when the user logs on. To provide enhanced security management of URL Actions in Internet Explorer, you can use the new Security Page Group Policy settings. MIME sniff indicates that the file is actually an executable file, Internet Explorer renames the file by saving it in the Internet Explorer cache and changing its extension. Group Policy Management Console online Help. Internet Explorer places restrictions on each Web page it opens.
For each of the Security Features policy settings, you can specify policy settings that control the behavior of the security features, by Internet Explorer processes, a list of defined processes, or all processes regardless of where they are initiated from. Doing this helps prevent users from lowering security to unacceptable levels. Minimum value for URL action network flags. There are many ways to configure policy settings for Internet Explorer. These policy settings apply to all processes which have opted in to the security restriction. For example, if users need to use a particular extranet application and this application does not operate because a restriction in Windows XP with SP2 prevents it from doing so, you might set a policy setting that allows a URL Action to permit that application to run.
If you need to specify individual URL Actions that differ from those in a given security zones policy template, you can configure individual policy settings to control that URL Action. List policy setting are denied. This feature helps to mitigate attacks that use the Local Machine zone to load malicious HTML code. Users use the Trusted Sites zone for content located on Web sites that are considered more reputable or trustworthy than other sites on the Internet. SP2 introduces new Security Features Group Policy settings for Internet Explorer that you can use to control various security aspects of Internet Explorer. To prevent such attacks, you can use the Protection from Zone Elevation policy setting.
Controls MIME sniffing for file promotion from one type to another based on a MIME sniff. This approach provided limited manageability because users could change their preference settings by using the Internet Explorer user interface or the registry. XP with SP2, you can manage all Internet Explorer security settings for both computer and user configurations with these new policy settings, making true policies secure and set only by an administrator. Internet Explorer contains dynamic binary behaviors: components that encapsulate specific functionality for the HTML elements to which they are attached. It is expected that doing so would be primarily to address application compatibility issues, which might require disabling an Internet Explorer functionality to allow an application to run. In contrast to user preference settings, these new policy settings are written to a secure tree in the registry so that users cannot change either by using the UI or through the registry. You can then apply such GPOs to specific groups of users or computers by using security group filtering to target the GPO to such groups.
Down Local Machine Zone. However, while trying it out on a system you must enter it as one line without breaks. Internet Explorer divides URL namespaces into URL security zones, which are assigned different levels of trust. If you set this policy setting for either computers or users, lists that are stored as preferences are ignored.

You can add up to 16 custom components that your users can install at the same time that they install the browser. The Network Protocol Lockdown security restrictions control a list of restricted protocols. This approach allows you to fine tune the URL Actions policy settings as necessary. XP with SP2, in addition to using individual policy settings for managing URL Actions, you can control URL Actions by using template policy settings which provide standard policy settings for all URL Actions in a particular Internet Explorer security zone. When this policy setting is enabled, it automatically populates the process list with Explorer.
This is the default security level for Restricted Sites zone. Zone Elevation also disables JavaScript navigation if there is no security context. This is an implicit zone for content that exists on the local computer. URL Actions correspond to security settings in the registry that identify the action to take for that feature in the security zone where the URL resides. As an example, consider zone elevation behavior. Configuration of options in the Internet Explorer Advanced tab. There are zone numbers which have associated security settings that apply to all of the sites in the zone.
Determines if Move or Copy operations are allowed.

Group Policy is the recommended tool for managing Internet Explorer for client computers on a corporate network. You can create separate GPOs and specify URL Actions policy settings tailored to the particular requirements of groups of users and computers. The list of restricted protocols for each zone can be set in the Restricted Protocols section under Network Protocol Lockdown policy. This default setting causes Internet Explorer to prompt the user whenever potentially unsafe content is ready to download.
By default, the Internet Option control panel displays policy settings when opened, and users can interact with the user interface and appear to change their preferences. This policy setting controls whether the Binary Behavior Security Restriction setting is prevented or allowed. If you set individual URL Action policy settings in a security zone, and then set a security template for that zone, this overwrites the values for individual URL Action policy settings. The Scripted Window Restrictions security feature restricts popup windows and prohibits scripts from displaying windows in which the title and status bars are not visible to the user or obfuscate other title and status bars. These policy settings provide you with more flexibility in managing specific scenarios that might affect security of Internet Explorer.

Am I doing the right thing by disabling them on the Internet zone?
These binary behaviors are not controlled by any Internet Explorer security setting, allowing them to work on Web pages in the Restricted Sites zone. If the user has local administrator privilages then Binary and Script Behaviors could potentially be very dangerous. From what I understand Binary and Script Behaviors are run with the same privilages as the user. What I got away from it was that Binary Scripts and Behaviors are now disabled by default in the Restricted Zone. Thank you very much for your reply. Comprehensive resources; exceptional value. In combination with the Local Machine Lockdown security feature, you require administrative approval for binary behaviors to run in the Local Machine zone by default. Binary behaviors differ from attached behaviors and element behaviors, which are written in script.
HTML elements, which encapsulate specific functionality. To use binary behaviors from the Restricted Sites zone, an application can also implement a custom security manager. Applications that host the WebBrowser control and use Internet Explorer functionality in the Restricted Sites zone might be affected. In the Restricted Sites zone, the default value is Disable. How Can I Work Around This Problem? What Happens If I Disable This Security Feature? It is not recommended that this feature be left disabled on an ongoing basis.
