Users who change their Internet Explorer security settings could enable the execution of dangerous types of code from the Internet and web sites listed in the Restricted Sites zone in the browser. This setting enforces consistent security zone settings to all users of the computer. Security zones control browser behavior at various web sites and it is desirable to maintain a consistent policy for all users of a machine. This policy setting affects how security zone changes apply to different users. If you enable this policy setting, changes that one user makes to a security zone will apply to all users of that computer. If this policy setting is disabled or not configured, users of the same computer are allowed to establish their own security zone settings.System AdministratorECSC-1

Users who change their Internet Explorer security settings could enable the execution of dangerous types of code from the Internet and web sites listed in the Restricted Sites zone in the browser. This setting prevents users from changing the Internet Explorer policies on the machine. Policy changes should be made by administrators only, so this setting should be enabled. If you enable this policy setting, you disable the Custom level button and Security level for 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.System AdministratorECSC-1

This parameter ensures only DoD-approved ciphers and algorithms are enabled for use by the web browser. TLS is a protocol for protecting communication between the browser and the target server. When the browser attempts to set up a protected communication with the target server, the browser and server negotiate which protocol and version to use. The browser and server attempt to match each other’s list of supported protocols and versions and pick the most preferred match. System AdministratorECSC-1

Active X controls can contain potentially malicious code and must only be allowed to be downloaded from trusted sites. Signed code is better than unsigned code in that it may be easier to determine its author, but it is still potentially harmful, especially when coming from an untrusted zone. This policy setting allows you to manage whether users may download signed ActiveX controls from a page in the zone. If you enable this policy, users can download signed controls without user intervention. If you select Prompt in the drop-down box, users are queried whether to download controls signed by untrusted publishers. Code signed by trusted publishers is silently downloaded.

ActiveX controls that are not marked safe scripting should not be executed. Although this is not a complete security measure for a control to be marked safe for scripting, if a control is not marked safe, it should not be initialized and executed. This setting causes both unsafe and safe controls to be initialized and scripted, ignoring the Script ActiveX controls marked safe for scripting option. This increases the risk of malicious code being loaded and executed by the browser. If you enable this policy setting, ActiveX controls are run, loaded with parameters and scripted without setting object safety for untrusted data or scripts. If you disable this policy setting, ActiveX controls that cannot be made safe are not loaded with parameters or scripted. This setting is not recommended, except for secure and administered zones.

This setting controls whether users can participate in the Microsoft Customer Experience Improvement Program to help improve Microsoft applications. When users choose to participate in the Customer Experience Improvement Program (CEIP), applications automatically send information to Microsoft about how the applications are used. This information is combined with other CEIP data to help Microsoft solve problems and to improve the products and features customers use most often. This feature does not collect users' names, addresses, or any other identifying information except the IP address that is used to send the data. By default, users have the opportunity to opt into participation in the CEIP the first time they run an application. If an organization has policies that govern the use of external resources such as the CEIP, allowing users to opt in to the program might cause them to violate these policies.Information Assurance OfficerSystem AdministratorECSC-1

Internet Explorer uses Multipurpose Internet Mail Extensions (MIME) data to determine file handling procedures for files received through a web server. The Consistent MIME Handling\Internet Explorer Processes policy setting determines whether Internet Explorer requires all file-type information provided by web servers be consistent. For example, if the MIME type of a file is text/plain but the MIME data indicates the file is really an executable file, Internet Explorer changes its extension to reflect this executable status. This capability helps ensure executable code cannot masquerade as other types of data that may be trusted. If you enable this policy setting, Internet Explorer examines all received files and enforces consistent MIME data for them. If you disable or do not configure this policy setting, Internet Explorer does not require consistent MIME data for all received files and will use the MIME data provided by the file. MIME file-type spoofing is a potential threat to an organization. Ensuring these files are consistent and properly labeled helps prevent malicious file downloads from infecting your network.

MIME sniffing is the process of examining the content of a MIME file to determine its context — whether it is a data file, an executable file, or some other type of file. This policy setting determines whether Internet Explorer MIME sniffing will prevent promotion of a file of one type to a more dangerous file type. When set to Enabled, MIME sniffing will never promote a file of one type to a more dangerous file type. Disabling MIME sniffing configures Internet Explorer processes to allow a MIME sniff that promotes a file of one type to a more dangerous file type. For example, promoting a text file to an executable file is a dangerous promotion because any code in the supposed text file would be executed. MIME file-type spoofing is a potential threat to an organization. Ensuring these files are consistently handled helps prevent malicious file downloads from infecting the network. This guide recommends you configure this policy as Enabled for all environments specified in this guide.

Web pages on a local computer have the fewest security restrictions and reside in the Local Machine Zone, which makes the Local Machine Security Zone a prime target for malicious attackers. If you enable this policy setting, any zone can be protected from zone elevation by Internet Explorer processes. This approach stops content running in one zone from gaining the elevated privileges of another zone. If you disable this policy setting, no zone receives such protection for Internet Explorer processes.

Internet Explorer uses Multipurpose Internet Mail Extensions (MIME) data to determine file handling procedures for files received through a web server. The Consistent MIME Handling\Internet Explorer Processes policy setting determines whether Internet Explorer requires all file-type information provided by web servers be consistent. For example, if the MIME type of a file is text/plain but the MIME data indicates the file is really an executable file, Internet Explorer changes its extension to reflect this executable status. This capability helps ensure executable code cannot masquerade as other types of data that may be trusted. If you enable this policy setting, Internet Explorer examines all received files and enforces consistent MIME data for them. If you disable or do not configure this policy setting, Internet Explorer does not require consistent MIME data for all received files and will use the MIME data provided by the file. MIME file-type spoofing is a potential threat to the organization. Ensuring these files are consistent and properly labeled helps prevent malicious file downloads from infecting the network.

The Turn off Crash Detection policy setting allows you to manage the crash detection feature of add-on management in Internet Explorer. If you enable this policy setting, a crash in Internet Explorer will be similar to one on a computer running Windows XP Professional Service Pack 1 and earlier; Windows Error Reporting will be invoked. If you disable this policy setting, the crash detection feature in add-on management will be functional. Because Internet Explorer crash report information could contain sensitive information from the computer's memory, this guide recommends configuring this option to Enabled unless experiencing frequent repeated crashes and need to report them for follow-up troubleshooting. In those cases, you could temporarily configure the setting to Disabled.System AdministratorECSC-1

MIME sniffing is the process of examining the content of a MIME file to determine its context — whether it is a data file, an executable file, or some other type of file. This policy setting determines whether Internet Explorer MIME sniffing will prevent promotion of a file of one type to a more dangerous file type. When set to Enabled, MIME sniffing will never promote a file of one type to a more dangerous file type. Disabling MIME sniffing configures Internet Explorer processes to allow a MIME sniff that promotes a file of one type to a more dangerous file type. For example, promoting a text file to an executable file is a dangerous promotion because any code in the supposed text file would be executed. MIME file-type spoofing is a potential threat to an organization. Ensuring these files are consistently handled helps prevent malicious file downloads from infecting the network. This guide recommends configuring this policy as Enabled for all environments specified in this guide.
