This parameter ensures only DoD-approved ciphers and algorithms are enabled for use by the web browser. TLS and SSL are by allowing you to turn on/off support for TLS and SSL. TLS is a protocols for protecting communications 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.ECSC-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. If you disable the policy setting, signed controls cannot be downloaded.DCMC-1

Discussion

ActiveX controls that are not marked safe for 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.DCMC-1

Java applications could contain malicious code; sites located in this security zone are more likely to be hosted by malicious individuals. This policy setting allows you to manage permissions for Java applets. If you enable this policy setting, options can be chosen from the drop-down box. Use of the Custom permission will control permissions settings individually. Use of the Low Safety permission enables applets to perform all operations. Use of the Medium Safety permission enables applets to run in their sandbox (an area in memory outside of which the program cannot make calls), plus adds capabilities like scratch space (a safe and secure storage area on the client computer) and a user-controlled file I/O. Use of the High Safety permission enables applets to run in their sandbox. If you disable this policy setting, Java applets cannot run. If you do not configure this policy setting, the permission is set to High Safety.DCMC-1

Users could submit credentials to servers operated by malicious individuals who could then attempt to connect to legitimate servers with those captured credentials. Care must be taken with user credentials, automatic logon performance, and how default Windows credentials are passed to the websites. This policy setting allows management of settings for logon options. If you enable this policy setting, you can choose from varying logon options. “Anonymous logon” disables HTTP authentication and uses the guest account only for the Common Internet File System (CIFS) protocol. “Prompt for user name and password” queries users for user IDs and passwords. After a user is queried, these values can be used silently for the remainder of the session. “Automatic logon only in Intranet zone” queries users for user IDs and passwords in other zones. After a user is queried, these values can be used silently for the remainder of the session. “Automatic logon with current user name and password” attempts logon using Windows NT Challenge Response. If Windows NT Challenge Response is supported by the server, the logon uses the user's network user name and password for login. If Windows NT Challenge Response is not supported by the server, the user is queried to provide the user name and password. If you disable this policy setting, logon is set to “Automatic logon only in Intranet zone”. If you do not configure this policy setting, logon is set to “Automatic logon only in Intranet zone”. The most secure option is to configure this setting to “Enabled”; “Anonymous logon”, but configuring this setting to “Enabled”; “Prompt for user name and password”, provides a reasonable balance between security and usability.ECSC-1

Users could submit credentials to servers operated by malicious individuals who could then attempt to connect to legitimate servers with those captured credentials. Care must be taken with user credentials, automatic logon performance, and how default Windows credentials are passed to the websites. This policy setting allows management of settings for logon options. If you enable this policy setting, you can choose from varying logon options. “Anonymous logon” disables HTTP authentication and uses the guest account only for the Common Internet File System (CIFS) protocol. “Prompt for user name and password” queries users for user IDs and passwords. After a user is queried, these values can be used silently for the remainder of the session. “Automatic logon only in Intranet zone” queries users for user IDs and passwords in other zones. After a user is queried, these values can be used silently for the remainder of the session. “Automatic logon with current user name and password” attempts logon using Windows NT Challenge Response. If Windows NT Challenge Response is supported by the server, the logon uses the user's network user name and password for login. If Windows NT Challenge Response is not supported by the server, the user is queried to provide the user name and password. If you disable this policy setting, logon is set to “Automatic logon only in Intranet zone”. If you do not configure this policy setting, logon is set to “Automatic logon only in Intranet zone”.

This policy setting allows you to manage whether Internet Explorer will check revocation status of servers' certificates. Certificates are revoked when they have been compromised or are no longer valid, and this option protects users from submitting confidential data to a site that may be fraudulent or not secure. If you enable this policy setting, Internet Explorer will check to see if server certificates have been revoked. If you disable this policy setting, Internet Explorer will not check server certificates to see if they have been revoked. If you do not configure this policy setting, Internet Explorer will not check server certificates to see if they have been revoked.IATS-1, IATS-2

Some UNC paths could refer to servers not managed by the organization, which means they could host malicious content; and therefore, it is safest to not include all UNC paths in the Intranet Sites zone. This policy setting controls whether URLs representing UNCs are mapped into the local Intranet security zone. If you enable this policy setting, all network paths are mapped into the Intranet Zone. If you disable this policy setting, network paths are not necessarily mapped into the Intranet Zone (other rules might map one there). If you do not configure this policy setting, users choose whether network paths are mapped into the Intranet Zone.ECSC-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 to 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.ECSC-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.

The MK Protocol Security Restriction policy setting reduces attack surface area by blocking the seldom used MK protocol. Some older web applications use the MK protocol to retrieve information from compressed files. Because the MK protocol is not widely used, it should be blocked wherever it is not needed. Setting this policy to "Enabled"; blocks the MK protocol for Windows Explorer and Internet Explorer, which causes resources that use the MK protocol to fail. Disabling this setting allows applications to use the MK protocol API. This guide recommends configuring this setting to "Enabled" to block the MK protocol unless it is specifically needed in the environment.

Internet Explorer places restrictions on each web page it opens that are dependent upon the location of the web page (such as Internet Zone, Intranet Zone, or Local Machine Zone). 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 from Internet Explorer processes. Because of the severity and relative frequency of zone elevation attacks, this guide recommends that you configure this setting as "Enabled" in all environments.ECSC-1

This setting is important from a security perspective because Microsoft has extensive data illustrating the positive impact the SmartScreen filter has had on reducing the risk of malware infection via visiting malicious websites. This policy setting allows users to enable the SmartScreen Filter, which will warn if the website being visited is known for fraudulent attempts to gather personal information through 'phishing' or is known to host malware. If you enable this setting the user will not be prompted to enable the SmartScreen Filter. It must be specified which mode the SmartScreen Filter uses: On or Off. If the feature is On, all website addresses not contained on the filters allow list, will be sent automatically to Microsoft without prompting the user. If this feature is set to Off, the feature will not run. If you disable or do not configure this policy setting, the user is prompted to decide whether to turn on SmartScreen Filter during the first-run experience.ECSC-1

This setting prevents ActiveX controls from running in Protected Mode when Enhanced Protected Mode is enabled. When a user has an ActiveX control installed that is not compatible with Enhanced Protected Mode and a website attempts to load the control, Internet Explorer notifies the user and gives the option to run the website in regular Protected Mode. This policy setting disables this notification and forces all websites to run in Enhanced Protected Mode. Enhanced Protected Mode provides additional protection against malicious websites by using 64-bit processes on 64-bit versions of Windows. For computers running at least Windows 8, Enhanced Protected Mode also limits the locations Internet Explorer can read from in the registry and the file system. If you enable this policy setting, Internet Explorer will not give the user the option to disable Enhanced Protected Mode. All Protected Mode websites will run in Enhanced Protected Mode. If you disable or do not configure this policy setting, Internet Explorer notifies users and provides an option to run websites with incompatible ActiveX controls in regular Protected Mode.ECSC-1

This policy setting prevents Internet Explorer from displaying a notification when the average time it takes to load all the user's enabled add-ons exceeds the threshold. The notification informs the user that add-ons are slowing their browsing and displays a button which opens the Disable Add-ons dialog box. The Disable Add-ons dialog box displays the load time for each group of add-ons enabled in the browser. It allows the user to disable add-ons and configure the threshold. If you enable this policy setting, users will not be notified when the average time it takes to load all the user's enabled add-ons exceeds the threshold.ECSC-1

This setting has a small impact on user privacy because users may unknowingly allow their browser to share location data with web sites that they visit. The value of enabling this setting is diminished due to the fact that malicious websites can learn a great deal about the location of a user merely by analyzing their IP address. If you enable this policy setting, Browser Geolocation support will be turned off. If you disable this policy setting, Browser Geolocation will be turned on. If you do not configure this setting, Browser Geolocation support can be turned on or off in Internet Options on the "Privacy" tab.ECSC-1

This policy setting allows you to turn off the ActiveX opt-in prompt. The ActiveX opt-in prevents websites from loading any COM object without prior approval. If a page attempts to load a COM object that Internet Explorer has not used before, an information bar will appear asking the user for approval. If you enable this policy setting, the ActiveX opt-in prompt will not appear. Internet Explorer does not ask the user for permission to load a control, and will load the ActiveX if it passes all other internal security checks. If you disable or do not configure this policy setting the ActiveX opt-in prompt will appear.ECSC-1
