This parameter warns users if the certificate being presented by the website is invalid. Since server certificates are used to validate the identity of the web server it is critical to warn the user of a potential issue with the certificate being presented by the web server. This setting aids to prevent spoofing attacks.

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.

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.

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.

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

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”. This will prevent users from submitting credentials to servers in this security zone.

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.

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.

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.

InPrivate Browsing lets the user control whether or not Internet Explorer saves the browsing history, cookies, and other data. User control of settings is not the preferred control method. The InPrivate Browsing feature in Internet Explorer makes browser privacy easy by not storing history, cookies, temporary Internet files, or other data. If you enable this policy setting, InPrivate Browsing will be disabled. If you disable this policy setting, InPrivate Browsing will be available for use. If you do not configure this setting, InPrivate Browsing can be turned on or off through the registry.

Unsigned components are more likely to contain malicious code and it is more difficult to determine the author of the application - therefore they should be avoided if possible. This policy setting allows you to manage whether .NET Framework components that are not signed with Authenticode can be executed from Internet Explorer. These components include managed controls referenced from an object tag and managed executables referenced from a link. If you enable this policy setting, Internet Explorer will execute unsigned managed components.

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.

This parameter ensures only DoD-approved ciphers and algorithms are enabled for use by the web browser by allowing you to turn on/off support for TLS and SSL. TLS is a protocol 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.

Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. Organization-defined time periods for updating security-relevant software may vary based on a variety of factors including, for example, the security category of the information system or the criticality of the update (i.e., severity of the vulnerability related to the discovered flaw). This requirement will apply to software patch management solutions that are used to install patches across the enclave and also to applications that are not part of that patch management solution. For example, many browsers today provide the capability to install their own patch software. Patch criticality, as well as system criticality, will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may depend on the Information Assurance Vulnerability Management (IAVM) process.
