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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><IAControls>ECSC-1</IAControls>DPMS Target IE Version 9DISA FSODPMS TargetIE Version 92185Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer “Security Zones: Use only machine settings” to “Enabled”.

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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><IAControls>ECSC-1</IAControls>DPMS Target IE Version 9DISA FSODPMS TargetIE Version 92185Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer “Security Zones: Do not allow users to change policies” to “Enabled”.

DTBI014- IE TLS Setting<GroupDescription></GroupDescription>DTBI014The IE TLS parameter must be set correctly.<VulnDiscussion>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. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><IAControls>ECSC-1</IAControls>DPMS Target IE Version 9DISA FSODPMS TargetIE Version 92185Open Internet Explorer.

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. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><IAControls>DCMC-1</IAControls>DPMS Target IE Version 9DISA FSODPMS TargetIE Version 92185Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Internet Zone -> "Initialize and script ActiveX controls not marked as safe" to “Enabled” and select "Disable" from the drop-down box.The policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Internet Zone -> "Initialize and script ActiveX controls not marked as safe" must be “Enabled” and "Disable" selected from the drop-down box.

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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Information Assurance Officer</Responsibility><Responsibility>System Administrator</Responsibility><IAControls>ECSC-1</IAControls>DPMS Target IE Version 9DISA FSODPMS TargetIE Version 92185CCE-495Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> "Prevent participation in the Customer Experience Improvement Program" to “Enabled”.The policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> "Prevent participation in the Customer Experience Improvement Program" must be “Enabled”.

DTBI590 - MIME handling - Reserved<GroupDescription></GroupDescription>DTBI590Internet Explorer Processes for MIME handling must be enforced (Reserved).<VulnDiscussion>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. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Information Assurance Officer</Responsibility><Responsibility>System Administrator</Responsibility><IAControls>ECSC-1</IAControls>DPMS Target IE Version 9DISA FSODPMS TargetIE Version 92185CCE-382Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Security Features -> Consistent Mime Handling -> "Internet Explorer Processes" to “Enabled”.

Criteria: If the value (Reserved) is REG_SZ = 1, this is not a finding.DTBI595 - MIME sniffing - Reserved<GroupDescription></GroupDescription>DTBI595Internet Explorer Processes for MIME sniffing must be enforced (Reserved).<VulnDiscussion>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.
