Vuln Rule Version CCI Severity Title Description
SV-40549r1_rule DTBI320 MEDIUM Internet Explorer must be configured to use machine settings. 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
SV-40552r1_rule DTBI319 MEDIUM Internet Explorer must be configured to disallow users to change policies. 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
SV-40553r1_rule DTBI318 MEDIUM Internet Explorer must be set to disallow users to add/delete sites. This setting prevents users from adding sites to various security zones. Users should not be able to add sites to different zones, as this could allow them to bypass security controls of the system. If you do not configure this policy setting, users will be able to add or remove sites from the Trusted Sites and Restricted Sites zones at will and change settings in the Local Intranet zone. This configuration could allow sites that host malicious mobile code to be added to these zones, which users could execute.System AdministratorECSC-1
SV-40555r1_rule DTBI367 LOW Internet Explorer must be configured to make Proxy settings per user. This setting controls whether or not the Internet Explorer proxy settings are configured on a per-user or per-machine basis. If you enable this policy, users cannot set user specific proxy settings. They must use the zones created for all users of the computer. If you disable this policy or do not configure it, users of the same computer can establish their own proxy settings. This policy is intended to ensure that proxy settings apply uniformly to the same computer and do not vary from user to user.System AdministratorECSC-1
SV-40558r1_rule DTBI022 MEDIUM The Download signed ActiveX controls property must be disallowed (Internet zone). 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.System AdministratorDCMC-1
SV-40559r1_rule DTBI023 MEDIUM The Download unsigned ActiveX controls property must be disallowed (Internet zone). Unsigned code is potentially harmful, especially when coming from an untrusted zone. This policy setting allows you to manage whether users may download unsigned ActiveX controls from the zone. If you enable this policy setting, users can run unsigned controls without user intervention. If you select Prompt in the drop-down box, users are queried to choose whether to allow the unsigned control to run. If you disable this policy setting, users cannot run unsigned controls. If you do not configure this policy setting, users cannot run unsigned controls.System AdministratorDCMC-1
SV-40561r1_rule DTBI024 MEDIUM The Initialize and script ActiveX controls not marked as safe property must be disallowed (Internet zone). 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. System AdministratorDCMC-1
SV-40563r1_rule DTBI030 MEDIUM Font downloads must be disallowed (Internet zone). Download of fonts can sometimes contain malicious code. It is possible that a font could include malformed data that would cause Internet Explorer to crash when it attempts to load and render the font. This policy setting allows you to manage whether pages of the zone may download HTML fonts. If you enable this policy setting, HTML fonts can be downloaded automatically. If you enable this policy setting and prompt is selected in the drop-down box, users are queried whether to allow HTML fonts to download. If you disable this policy setting, HTML fonts are prevented from downloading.System AdministratorDCMC-1
SV-40565r2_rule DTBI031 MEDIUM The Java Permissions must be disallowed (Internet zone). Java applications could contain malicious code; sites located in this security zone are more likely to be hosted by malicious people. 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 Custom will control permissions settings individually. Use of Low Safety enables applets to perform all operations. Use of Medium Safety enables applets to run in their sandbox (an area in memory outside of which the program cannot make calls), plus capabilities like scratch space (a safe and secure storage area on the client computer) and user-controlled file I/O. Use of High Safety 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.System AdministratorDCMC-1
SV-40567r1_rule DTBI032 MEDIUM Accessing data sources across domains must be disallowed (Internet zone). The ability to access data zones across domains could cause the user to unknowingly access content hosted on an unauthorized server. Access to data sources across multiple domains must be controlled based upon the site being browsed. This policy setting allows you to manage whether Internet Explorer can access data from another security zone using the Microsoft XML Parser (MSXML) or ActiveX Data Objects (ADO).System AdministratorDCMC-1
SV-40568r1_rule DTBI036 MEDIUM Functionality to drag and drop or copy and paste files must be disallowed (Internet zone). Content hosted on sites located in the Internet zone are likely to contain malicious payloads and therefore this feature should be blocked for this zone. Drag and Drop or copy and paste files must have a level of protection based upon the site being accessed.System AdministratorECSC-1
SV-40572r1_rule DTBI038 MEDIUM Launching programs and files in IFRAME must be disallowed (Internet zone). This policy setting allows you to manage whether applications may be run and files may be downloaded from an IFRAME reference in the HTML of the pages in this zone. Launching of programs in IFRAME must have a level of protection based upon the site being accessed. If you enable this policy setting, applications can run and files can be downloaded from IFRAMEs on the pages in this zone without user intervention. If you disable this setting, users are prevented from running applications and downloading files from IFRAMEs on the pages in this zone.System AdministratorDCMC-1
SV-40573r1_rule DTBI039 MEDIUM Navigating windows and frames across different domains must be disallowed (Internet zone). Frames that navigate across different domains are a security concern, because the user may think they are accessing pages on one site while they are actually accessing pages on another site. It is possible that a web site hosting malicious content could use this feature in a manner similar to cross site scripting. This policy setting allows you to manage the opening of sub-frames and access of applications across different domains. System AdministratorECSC-1
SV-40577r1_rule DTBI042 MEDIUM Userdata persistence must be disallowed (Internet zone). Userdata persistence must have level of protection based upon the site being accessed. This policy setting allows you to manage the preservation of information in the browser's history, in favorites, in an XML store, or directly within a web page saved to disk. When a user returns to a persisted page, the state of the page can be restored if this policy setting is not appropriately configured. System AdministratorECSC-1
SV-40578r1_rule DTBI044 MEDIUM Clipboard operations via script must be disallowed (Internet zone). A malicious script could use the clipboard in an undesirable manner, for example, if the user had recently copied confidential information to the clipboard while editing a document, a malicious script could harvest that information. It might be possible to exploit other vulnerabilities in order to send the harvested data to the attacker. Allow paste operations via script must have level of protection based upon the site being accessed. System AdministratorECSC-1
SV-40580r1_rule DTBI046 MEDIUM Logon options must be configured to prompt (Internet zone). Users could submit credentials to servers operated by malicious people 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 web sites. System AdministratorECSC-1
SV-40582r2_rule DTBI061 MEDIUM Java Permissions must be configured with High Safety (Intranet zone). Java applications could contain malicious code; sites located in this security zone are more likely to be hosted by malicious people. 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 Custom will control permissions settings individually. Use of Low Safety enables applets to perform all operations. Use of Medium Safety enables applets to run in their sandbox (an area in memory outside of which the program cannot make calls), plus capabilities like scratch space (a safe and secure storage area on the client computer) and user-controlled file I/O. Use of High Safety 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.System AdministratorDCMC-1
SV-40583r2_rule DTBI091 MEDIUM The Java Permissions must be set with High Safety (Trusted Sites zone). Java applications could contain malicious code; sites located in this security zone are more likely to be hosted by malicious people. 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 Custom will control permissions settings individually. Use of Low Safety enables applets to perform all operations. Use of Medium Safety enables applets to run in their sandbox (an area in memory outside of which the program cannot make calls), plus capabilities like scratch space (a safe and secure storage area on the client computer) and user-controlled file I/O. Use of High Safety 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.System AdministratorDCMC-1
SV-40586r1_rule DTBI112 MEDIUM The Download signed ActiveX controls property must be disallowed (Restricted Site zone). ActiveX 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. System AdministratorDCMC-1
SV-40587r1_rule DTBI113 MEDIUM The Download unsigned ActiveX controls property must be disallowed (Restricted Site zone). Unsigned code is potentially harmful, especially when coming from an untrusted zone. ActiveX controls can contain potentially malicious code and must only be allowed to be downloaded from trusted sites and they must be digitally signed.System AdministratorDCMC-1
SV-40588r1_rule DTBI114 MEDIUM The Initialize and script ActiveX controls not marked as safe property must be disallowed (Restricted Site zone). ActiveX controls 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.System AdministratorDCMC-1
SV-40590r1_rule DTBI115 MEDIUM ActiveX controls and plug-ins must be disallowed (Restricted Sites zone). This policy setting allows you to manage whether ActiveX controls and plug-ins can be run on pages from the specified zone. ActiveX controls not marked as safe should not be executed. If you enable this policy setting, controls and plug-ins can run without user intervention. If you disable this policy setting, controls and plug-ins are prevented from running.System AdministratorDCMC-1
SV-40591r1_rule DTBI116 MEDIUM ActiveX controls marked safe for scripting must be disallowed (Restricted Sites zone). This policy setting allows management of whether ActiveX controls marked safe for scripting can interact with a script. If you enable this policy setting, script interaction can occur automatically without user intervention. ActiveX controls not marked as 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.System AdministratorDCMC-1
SV-40602r1_rule DTBI119 MEDIUM File downloads must be disallowed (Restricted Site zone). Sites located in the Restricted Sites Zone are more likely to contain malicious payloads and therefore downloads from this zone should be blocked. Files should not be able to be downloaded from sites that are considered restricted. This policy setting allows you to manage whether file downloads are permitted from the zone. This option is determined by the zone of the page with the link causing the download, not the zone from which the file is delivered. System AdministratorDCMC-1
SV-40603r1_rule DTBI120 MEDIUM Font downloads must be disallowed (Restricted Site zone). It is possible that a font could include malformed data that would cause Internet Explorer to crash when it attempts to load and render the font. Download of fonts can sometimes contain malicious code. Files should not be downloaded from restricted sites. This policy setting allows you to manage whether pages of the zone may download HTML fonts.System AdministratorDCMC-1
SV-40604r1_rule DTBI122 MEDIUM Accessing data sources across domains must be disallowed (Restricted Sites zone). The ability to access data zones across domains could cause the user to unknowingly access content hosted on an unauthorized server. This policy setting allows you to manage whether Internet Explorer can access data from another security zone using the Microsoft XML Parser (MSXML) or ActiveX Data Objects (ADO). System AdministratorDCMC-1
SV-40606r1_rule DTBI123 MEDIUM The Allow META REFRESH property must be disallowed (Restricted Sites zone). It is possible that users will unknowingly be redirected to a site hosting malicious content. Allow META REFRESH must have level of protection based upon the site being browsed. This policy setting allows you to manage whether a user's browser can be redirected to another web page if the author of the web page uses the Meta Refresh setting to redirect browsers to another web page. System AdministratorDCMC-1
SV-40608r1_rule DTBI126 MEDIUM Functionality to drag and drop or copy and paste files must be disallowed (Restricted Sites zone). Content hosted on sites located in the Restricted Sites zone are more likely to contain malicious payloads and therefore this feature should be blocked for this zone. Drag and drop or copy and paste files must have a level of protection based upon the site being accessed.System AdministratorECSC-1
SV-40609r1_rule DTBI127 MEDIUM Installation of desktop items must be disallowed (Restricted Sites zone). Active Desktop items could contain links to unauthorized websites or other undesirable content. It is prudent to prevent users from installing desktop items from this security zone. Installation of items must have a level of protection based upon the site being accessed. This policy setting allows you to manage whether users can install Active Desktop items from this zone.System AdministratorDCMC-1
SV-40612r1_rule DTBI128 MEDIUM Launching programs and files in IFRAME must be disallowed (Restricted Sites zone). This policy setting allows you to manage whether applications may be run and files may be downloaded from an IFRAME reference in the HTML of the pages in this zone. Launching of programs in IFRAME must have a level of protection based upon the site being accessed. If you enable this policy setting, applications can run and files can be downloaded from IFRAMEs on the pages in this zone without user intervention. If you disable this setting, users are prevented from running applications and downloading files from IFRAMEs on the pages in this zone.System AdministratorDCMC-1
SV-40614r1_rule DTBI129 MEDIUM Navigating windows and frames across different domains must be disallowed (Restricted Sites zone). Frames navigating across different domains are a security concern, because the user may think they are accessing pages on one site while they are actually accessing pages on another site. It is possible that a web site hosting malicious content could use this feature in a manner similar to cross site scripting. This policy setting allows you to manage the opening of sub-frames and access of applications across different domains. System AdministratorECSC-1
SV-40616r1_rule DTBI132 MEDIUM Userdata persistence must be disallowed (Restricted Sites zone). Userdata persistence must have level of protection based upon the site being accessed. This policy setting allows you to manage the preservation of information in the browser's history, in favorites, in an XML store, or directly within a web page saved to disk. When a user returns to a persisted page, the state of the page can be restored if this policy setting is not appropriately configured. System AdministratorECSC-1
SV-40617r1_rule DTBI133 MEDIUM Active scripting must be disallowed (Restricted Sites Zone). Active scripts hosted on sites located in this zone are more likely to contain malicious code. Active scripting must have a level of protection based upon the site being accessed. This policy setting allows you to manage whether script code on pages in the zone are run.System AdministratorDCMC-1
SV-40618r1_rule DTBI134 MEDIUM Clipboard operations via script must be disallowed (Restricted Sites zone). A malicious script could use the clipboard in an undesirable manner, for example, if the user had recently copied confidential information to the clipboard while editing a document, a malicious script could harvest that information. It might be possible to exploit other vulnerabilities in order to send the harvested data to the attacker. Allow paste operations via script must have level of protection based upon the site being accessed. System AdministratorECSC-1
SV-40619r1_rule DTBI136 MEDIUM Logon options must be configured and enforced (Restricted Sites zone). Users could submit credentials to servers operated by malicious people 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 web sites. System AdministratorECSC-1
SV-40620r2_rule DTBI121 MEDIUM Java Permissions must be disallowed (Restricted Sites zone). Java applications could contain malicious code; sites located in this security zone are more likely to be hosted by malicious people. 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 Custom will control permissions settings individually. Use of Low Safety enables applets to perform all operations. Use of Medium Safety enables applets to run in their sandbox (an area in memory outside of which the program cannot make calls), plus capabilities like scratch space (a safe and secure storage area on the client computer) and user-controlled file I/O. Use of High Safety 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.System AdministratorDCMC-1
SV-40529r1_rule DTBI697 LOW Ability for users to enable or disable add-ons must be enforced. Users often choose to install add-ons that are not permitted by an organization's security policy. Such add-ons can pose a significant security and privacy risk to your network. This policy setting allows you to manage whether users have the ability to allow or deny add-ons through Add-On Manager. If you enable this policy setting, users cannot enable or disable add-ons through Add-On Manager. The only exception occurs if an add-on has been specifically entered into the 'Add-On List' policy setting in such a way as to allow users to continue to manage the add-on. In this case, the user can still manage the add-on. If you disable or do not configure this policy setting, the appropriate controls in the Add-On Manager will be available to the user. System AdministratorECSC-1
SV-40530r1_rule DTBI305 MEDIUM Automatic configuration of Internet Explorer must be disallowed. This setting specifies to automatically detect the proxy server settings used to connect to the Internet and customize Internet Explorer. This setting specifies that Internet Explorer use the configuration settings provided in a file by the system administrator. If you enable this policy setting, the user will not be able to do automatic configuration. You can import current connection settings using Internet Explorer Maintenance under Admin Templates using group policy editor. If you disable or do not configure this policy setting, the user will have the freedom to automatically configure these settings.Information Assurance OfficerSystem AdministratorECSC-1
SV-40531r1_rule DTBI315 MEDIUM Participation in the Customer Experience Improvement Program must be disallowed. 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
SV-40547r1_rule DTBI325 MEDIUM Security checking features must be enforced. This policy setting turns off the Security Settings Check feature, which checks Internet Explorer security settings to determine when the settings put Internet Explorer at risk. If you enable this policy setting, the security settings check will not be performed. If you disable or do not configure this policy setting, the security settings check will be performed.Information Assurance OfficerSystem AdministratorECSC-1
SV-40626r1_rule DTBI340 MEDIUM Active content from CDs must be disallowed to run on user machines. This policy setting allows you to manage whether users receive a dialog requesting permission for active content on a CD to run. If you enable this policy setting, active content on a CD will run without a prompt. If you disable this policy setting, active content on a CD will always prompt before running. If you do not configure this policy, users can choose whether to be prompted before running active content on a CD.Information Assurance OfficerSystem AdministratorECSC-1
SV-40627r1_rule DTBI350 MEDIUM Software must be disallowed to run or install with invalid signatures. Microsoft ActiveX controls and file downloads often have digital signatures attached that certify the file's integrity and the identity of the signer (creator) of the software. Such signatures help ensure unmodified software is downloaded and the user can positively identify the signer to determine whether you trust them enough to run their software. The validity of unsigned code cannot be ascertained. Some legitimate software and controls may have an invalid signature. You should carefully test such software in isolation before it is allowed to be used on an organization's network.System AdministratorInformation Assurance OfficerDCMC-1
SV-40628r1_rule DTBI355 MEDIUM Third-party browser extensions must be disallowed. This policy setting allows you to manage whether Internet Explorer will launch COM add-ons, known as browser helper objects such as toolbars. Browser helper objects may contain flaws such as buffer overruns which impact Internet Explorer's performance or stability. If you enable this policy setting, Internet Explorer automatically launches any browser helper objects that are installed on the user's computer. If you disable this policy setting, browser helper objects do not launch. If you do not configure this policy, Internet Explorer automatically launches any browser helper objects that are installed on the user's computer.Information Assurance OfficerSystem AdministratorECSC-1
SV-40629r1_rule DTBI365 MEDIUM Checking for server certificate revocation must be enforced. 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.System AdministratorInformation Assurance OfficerIATS-1, IATS-2
SV-40630r1_rule DTBI370 MEDIUM Checking for signatures on downloaded programs must be enforced. This policy setting allows you to manage whether Internet Explorer checks for digital signatures (which identifies the publisher of signed software and verifies it has not been modified or tampered with) on user computers before downloading executable programs. If you enable this policy setting, Internet Explorer will check the digital signatures of executable programs and display their identities before downloading them to user computers. If you disable this policy setting, Internet Explorer will not check the digital signatures of executable programs or display their identities before downloading them to user computers. If you do not configure this policy, Internet Explorer will not check the digital signatures of executable programs or display their identities before downloading them to user computers.Information Assurance OfficerSystem AdministratorECSC-1
SV-40632r1_rule DTBI375 MEDIUM All network paths (UNCs) for Intranet sites must be disallowed. 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.Information Assurance OfficerSystem AdministratorECSC-1
SV-40633r1_rule DTBI385 MEDIUM Script-initiated windows without size or position constraints must be disallowed (Internet zone). This policy setting allows you to manage restrictions on script-initiated pop-up windows and windows including the title and status bars. If you enable this policy setting, Windows Restrictions security will not apply in this zone. The security zone runs without the added layer of security provided by this feature. If you disable this policy setting, the possible harmful actions contained in script-initiated pop-up windows and windows including the title and status bars cannot be run. This Internet Explorer security feature will be on in this zone as dictated by the Scripted Windows Security Restrictions feature control setting for the process. If you do not configure this policy setting, the possible harmful actions contained in script-initiated pop-up windows and windows including the title and status bars cannot be run. This Internet Explorer security feature will be on in this zone as dictated by the Scripted Windows Security Restrictions feature control setting for the process.Information Assurance OfficerSystem AdministratorECSC-1
SV-40634r1_rule DTBI390 MEDIUM Script-initiated windows without size or position constraints must be disallowed (Restricted Sites zone). This policy setting allows you to manage restrictions on script-initiated pop-up windows and windows including the title and status bars. If you enable this policy setting, Windows Restrictions security will not apply in this zone. The security zone runs without the added layer of security provided by this feature.

This Internet Explorer security feature will be on in this zone as dictated by the Scripted Windows Security Restrictions feature control setting for the process.System AdministratorInformation Assurance OfficerECSC-1
SV-40635r1_rule DTBI395 MEDIUM Scriptlets must be disallowed (Internet zone). This policy setting allows you to manage whether scriptlets can be allowed. Scriptlets hosted on sites located in this zone are more likely to contain malicious code. If you enable this policy setting, users will be able to run scriptlets. If you disable this policy setting, users will not be able to run scriptlets. If you do not configure this policy setting, a scriptlet can be enabled or disabled by the user.Information Assurance OfficerSystem AdministratorECSC-1
SV-40636r1_rule DTBI415 MEDIUM Automatic prompting for file downloads must be disallowed (Internet zone). This policy setting determines whether users will be prompted for non user-initiated file downloads. Regardless of this setting, users will receive file download dialogs for user-initiated downloads. Users may accept downloads that they did not request, those downloaded files may include malicious code. If you enable this setting, users will receive a file download dialog for automatic download attempts. If you disable or do not configure this setting, file downloads that are not user-initiated will be blocked, and users will see the Information Bar instead of the file download dialog. Users can then click the Information Bar to allow the file download prompt.System AdministratorInformation Assurance OfficerECSC-1
SV-40637r2_rule DTBI425 MEDIUM Java permissions must be disallowed (Local Machine zone). Java applications could contain malicious code; sites located in this security zone are more likely to be hosted by malicious people. 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 Custom will control permissions settings individually. Use of Low Safety enables applets to perform all operations. Use of Medium Safety enables applets to run in their sandbox (an area in memory outside of which the program cannot make calls), plus capabilities like scratch space (a safe and secure storage area on the client computer) and user-controlled file I/O. Use of High Safety 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.Information Assurance OfficerSystem AdministratorDCMC-1

SV-40662r1_rule DTBI590 MEDIUM Internet Explorer Processes for MIME handling must be enforced (Reserved). 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.
