SRG-APP-000073
1 Rule
Bypassing Microsoft Defender SmartScreen prompts for sites must be disabled.
Medium Severity
This policy setting allows a decision to be made on whether users can override the Microsoft Defender SmartScreen warnings about potentially malicious websites. If this setting is enabled, users cannot ignore Microsoft Defender SmartScreen warnings, and are blocked from continuing to the site. If this setting is disabled or not configured, users can ignore Microsoft Defender SmartScreen warnings and continue to the site.
SRG-APP-000073
1 Rule
Bypassing of Microsoft Defender SmartScreen warnings about downloads must be disabled.
Medium Severity
This policy setting allows a decision to be made on whether users can override Microsoft Defender SmartScreen warnings about unverified downloads. If this setting is enabled, users cannot ignore Microsoft Defender SmartScreen warnings, and are prevented from completing the unverified downloads. If this policy is disabled or not configured, users can ignore Microsoft Defender SmartScreen warnings and complete unverified downloads.
SRG-APP-000073
1 Rule
The list of domains for which Microsoft Defender SmartScreen will not trigger warnings must be allowlisted if used.
Low Severity
Configure the list of Microsoft Defender SmartScreen trusted domains. This means Microsoft Defender SmartScreen will not check for potentially malicious resources, such as phishing software and other malware, if the source URLs match these domains. The Microsoft Defender SmartScreen download protection service will not check downloads hosted on these domains. If this policy is enabled, Microsoft Defender SmartScreen trusts these domains. If the policy is disabled or not set, default Microsoft Defender SmartScreen protection is applied to all resources.
SRG-APP-000080
1 Rule
InPrivate mode must be disabled.
Medium Severity
This setting specifies whether the user can open pages in InPrivate mode in Microsoft Edge. If this policy is not configured or set it to "Enabled", users can open pages in InPrivate mode. Set this policy to "Disabled" to stop users from using InPrivate mode. Set this policy to "Forced" to always use InPrivate mode. Policy options mapping: - Enabled (0) = InPrivate mode available - Disabled (1) = InPrivate mode disabled - Forced (2) = InPrivate mode forced
SRG-APP-000141
1 Rule
Background processing must be disabled.
Medium Severity
Background processing allows Microsoft Edge processes to start at OS sign-in and keep running after the last browser window is closed. In this scenario, background apps and the current browsing session remain active, including any session cookies. An open background process displays an icon in the system tray, and can be closed from there. If this policy is enabled, background mode is turned on. If this policy is disabled, background mode is turned off. If this policy is not configured, background mode is initially turned off, and the user can configure its behavior in edge://settings/system.
SRG-APP-000141
1 Rule
The ability of sites to show pop-ups must be disabled.
Medium Severity
Set whether websites can show pop-up windows. Pop-ups can be allowed on all websites ("AllowPopups") or blocked on all sites ("BlockPopups"). If this policy is configured, pop-up windows are blocked by default, and users can change this setting. Policy options mapping: - AllowPopups (1) = Allow all sites to show pop-ups. - BlockPopups (2) = Do not allow any site to show pop-ups.
SRG-APP-000141
1 Rule
The default search provider must be set to use an encrypted connection.
Medium Severity
Allows a list of list of up to 10 search engines to be configured, one of which must be marked as the default search engine. The encoding does not need to be specified. Starting in Microsoft Edge 80, the suggest_url and image_search_url parameters are optional. The optional parameter, image_search_post_params (consists of comma-separated name/value pairs), is available starting in Microsoft Edge 80. Starting in Microsoft Edge 83, search engine discovery can be enabled with the allow_search_engine_discovery optional parameter. This parameter must be the first item in the list. If allow_search_engine_discovery is not specified, search engine discovery will be disabled by default. Starting in Microsoft Edge 84, this policy can be set as a recommended policy to allow search provider discovery. The allow_search_engine_discovery optional parameter does not need to be added. If this policy is enabled, users cannot add, remove, or change any search engine in the list. Users can set their default search engine to any search engine in the list. If this policy is disabled or not configured, users can modify the search engines list as desired.
SRG-APP-000141
1 Rule
Data Synchronization must be disabled.
Low Severity

If this policy is enabled or not configured, users can control AutoFill for addresses in the user interface.
SRG-APP-000175
1 Rule
Online revocation checks must be performed.
Medium Severity
If you enable this policy, Microsoft Edge will perform soft-fail, online OCSP/CRL checks. "Soft fail" means that if the revocation server can't be reached, the certificate will be considered valid. If you disable the policy or don't configure it, Microsoft Edge won't perform online revocation checks.
SRG-APP-000141
1 Rule
Personalization of ads, search, and news by sending browsing history to Microsoft must be disabled.
Medium Severity
This policy prevents Microsoft from collecting a user's Microsoft Edge browsing history to be used for personalizing advertising, search, news and other Microsoft services. This setting is only available for users with a Microsoft account. This setting is not available for child accounts or enterprise accounts. If this policy is disabled, users cannot change or override the setting. If this policy is enabled or not configured, Microsoft Edge will default to the user's preference.
SRG-APP-000141
1 Rule
Site tracking of a user’s location must be disabled.
Medium Severity
Set whether websites can track users' physical locations. Tracking can be allowed by default ("AllowGeolocation") or denied by default ("BlockGeolocation"), or the user can be asked each time a website requests their location ("AskGeolocation"). If this policy is not configured, "AskGeolocation" is used and the user can change it. Policy options mapping: - AllowGeolocation (1) = Allow sites to track users' physical location. - BlockGeolocation (2) = Do not allow any site to track users' physical location. - AskGeolocation (3) = Ask whenever a site wants to track users' physical location.
SRG-APP-000080
1 Rule
Browser history must be saved.
Medium Severity
This setting disables deleting browser history and download history and prevents users from changing this setting.
SRG-APP-000141
1 Rule
Edge development tools must be disabled.
Low Severity
While the risk associated with browser development tools is more related to the proper design of a web application, a risk vector remains within the browser. The developer tools allow end users and application developers to view and edit all types of web application-related data via the browser. Page elements, source code, javascript, API calls, application data, etc., may all be viewed and potentially manipulated. Manipulation could be useful for troubleshooting legitimate issues, and this may be performed in a development environment. Manipulation could also be malicious and must be addressed.
SRG-APP-000141
1 Rule
Download restrictions must be configured.
Low Severity
Configure the type of downloads that Microsoft Edge completely blocks, without letting users override the security decision. Set "BlockDangerousDownloads" to allow all downloads except for those that carry Microsoft Defender SmartScreen warnings. Set "BlockPotentiallyDangerousDownloads" to allow all downloads except for those that carry Microsoft Defender SmartScreen warnings of potentially dangerous or unwanted downloads. Set "BlockAllDownloads" to block all downloads. If this policy is not configured or the 'DefaultDownloadSecurity' option set, downloads go through the usual security restrictions based on Microsoft Defender SmartScreen analysis results. Note that these restrictions apply to downloads from web page content, as well as the "download link..." context menu option. These restrictions do not apply to saving or downloading the currently displayed page, nor do they apply to the "Save as PDF" option from the printing options. See https://go.microsoft.com/fwlink/?linkid=2094934 for more information on Microsoft Defender SmartScreen. Policy options mapping: - DefaultDownloadSecurity (0) = No special restrictions. - BlockDangerousDownloads (1) = Block malicious downloads and dangerous file types. - BlockPotentiallyDangerousDownloads (2) = Block potentially dangerous or unwanted downloads and dangerous file types. - BlockAllDownloads (3) = Block all downloads. - BlockMaliciousDownloads (4) = Block malicious downloads.
SRG-APP-000378
1 Rule
URLs must be allowlisted for plugin use if used.
Low Severity
Define a list of sites, based on URL patterns that can open pop-up windows.
SRG-APP-000141
1 Rule
Extensions installation must be blocklisted by default.
Medium Severity
List specific extensions that users cannot install in Microsoft Edge. When this policy is deployed, any extensions on this list that were previously installed will be disabled, and the user will not be able to enable them. If an item is removed from the list of blocked extensions, the extension is automatically reenabled anywhere it was previously installed. Use "*" to block all extensions that are not explicitly listed in the allow list. If this policy is not configured, users can install any extension in Microsoft Edge.
SRG-APP-000386
1 Rule
Extensions that are approved for use must be allowlisted if used.
Low Severity
By default, all extensions are allowed. However, if all extensions are blocked by setting the "ExtensionInstallBlockList" policy to "*," users can only install extensions defined in this policy.
SRG-APP-000400
1 Rule
The Password Manager must be disabled.
Medium Severity
Enable Microsoft Edge to save user passwords. If this policy is enabled, users can save their passwords in Microsoft Edge. The next time the user visits the site, Microsoft Edge will enter the password automatically.
SRG-APP-000456
1 Rule
The version of Microsoft Edge running on the system must be a supported version.
High Severity
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 themselves 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 that the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may be dependent upon the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).
SRG-APP-000141
1 Rule
Site isolation for every site must be enabled.
Medium Severity
The "SitePerProcess" policy can be used to prevent users from opting out of the default behavior of isolating all sites. The "IsolateOrigins" policy can be used to isolate additional, finer-grained origins. Enabling this policy prevents users from opting out of the default behavior where each site runs in its own process. If this policy is not disabled or configured, a user can opt out of site isolation (e.g., by using "Disable site isolation" entry in edge://flags.) Disabling the policy or not configuring the policy does not turn off Site Isolation.
SRG-APP-000142
1 Rule
Supported authentication schemes must be configured.
Medium Severity
This setting specifies which HTTP authentication schemes are supported. The policy can be configured by using these values: "basic", "digest", "ntlm", and "negotiate". Separate multiple values with commas. If this policy is not configured, all four schemes are used.
SRG-APP-000141
1 Rule
Microsoft Defender SmartScreen must be enabled.
Medium Severity
This policy setting configures Microsoft Defender SmartScreen, which provides warning messages to help protect users from potential phishing scams and malicious software. By default, Microsoft Defender SmartScreen is turned on. If this setting is enabled, Microsoft Defender SmartScreen is turned on. If this setting is disabled, Microsoft Defender SmartScreen is turned off. If this setting is not configured, users can choose whether to use Microsoft Defender SmartScreen. This policy is available only on Windows instances that are joined to a Microsoft Active Directory domain, Windows 10 Pro or Enterprise instances that enrolled for device management, or macOS instances that are that are managed via MDM or joined to a domain via MCX.
SRG-APP-000141
1 Rule
Microsoft Defender SmartScreen must be configured to block potentially unwanted apps.
Medium Severity
This policy setting configures blocking for potentially unwanted apps with Microsoft Defender SmartScreen. Potentially unwanted app blocking with Microsoft Defender SmartScreen provides warning messages to help protect users from adware, coin miners, bundleware, and other low-reputation apps that are hosted by websites. Potentially unwanted app blocking with Microsoft Defender SmartScreen is turned off by default. If this setting is enabled, potentially unwanted app blocking with Microsoft Defender SmartScreen is turned on. If this setting is disabled, potentially unwanted app blocking with Microsoft Defender SmartScreen is turned off. If this setting is not configured, users can choose whether to use potentially unwanted app blocking with Microsoft Defender SmartScreen. This policy is available only on Windows instances that are joined to a Microsoft Active Directory domain, Windows 10 Pro or Enterprise instances that enrolled for device management, or macOS instances that are managed via MDM or joined to a domain via MCX.
SRG-APP-000141
1 Rule
The download location prompt must be configured.
Low Severity
This setting provides positive feedback before a download starts, limiting the possibility of inadvertent downloads without notifying the user.
SRG-APP-000148
1 Rule
Tracking of browsing activity must be disabled.
Medium Severity
The setting allows websites to be blocked from tracking users' web-browsing activity. If this policy is disabled or is not configured, users can set their own level of tracking prevention. Policy options mapping: - TrackingPreventionOff (0) = Off (no tracking prevention) - TrackingPreventionBasic (1) = Basic (blocks harmful trackers; content and ads will be personalized) - TrackingPreventionBalanced (2) = Balanced (blocks harmful trackers and trackers from sites user has not visited; content and ads will be less personalized) - TrackingPreventionStrict (3) = Strict (blocks harmful trackers and majority of trackers from all sites; content and ads will have minimal personalization; some parts of sites might not work)
SRG-APP-000149
1 Rule
A website's ability to query for payment methods must be disabled.
Medium Severity
This setting determines whether websites can check if the user has payment methods saved. If this policy is disabled, websites that use "PaymentRequest.canMakePayment" or "PaymentRequest.hasEnrolledInstrument" API will be informed that no payment methods are available. If this policy is enabled or is not set, websites can check to determine if the user has payment methods saved.
SRG-APP-000151
1 Rule
Suggestions of similar web pages in the event of a navigation error must be disabled.
Medium Severity
This setting allows Microsoft Edge to issue a connection to a web service to generate URL and search suggestions for connectivity issues such as DNS errors. If this policy is enabled, a web service is used to generate URL and search suggestions for network errors. If this policy is disabled, no calls to the web service are made and a standard error page is shown. If this policy is not configured, Microsoft Edge respects the user preference that is set under Services at edge://settings/privacy. Specifically, there is a "Suggest similar pages when a webpage can't be found" toggle, which the user can switch on or off. Note that if this policy has been enabled (AlternateErrorPagesEnabled), the "Suggest similar pages when a webpage can't be found setting" is turned on, but the user cannot change the setting by using the toggle. If this policy is disabled, the "Suggest similar pages when a webpage can't be found" setting is turned off, and the user cannot change the setting by using the toggle.
SRG-APP-000152
1 Rule
User feedback must be disabled.
Medium Severity
Microsoft Edge uses the Edge Feedback feature (enabled by default) to allow users to send feedback, suggestions, or customer surveys and to report any issues with the browser. By default, users cannot disable (turn off) the Edge Feedback feature. If this policy is enabled or not configured, users can invoke Edge Feedback. If this policy is disabled, users cannot invoke Edge Feedback.
SRG-APP-000153
1 Rule
The collections feature must be disabled.
Medium Severity
This setting allows users to access the Collections feature, where they can collect, organize, share, and export content more efficiently and with Office integration. If this policy is enabled or not configured, users can access and use the Collections feature in Microsoft Edge. If this policy is disabled, users cannot access and use Collections in Microsoft Edge.
SRG-APP-000141
1 Rule
The Share Experience feature must be disabled.
Medium Severity
If this policy is set to "ShareAllowed" (the default), users will be able to access the Windows 10 Share experience from the Settings and More menu in Microsoft Edge to share with other apps on the system. If this policy is set to "ShareDisallowed", users will not be able to access the Windows 10 Share experience. If the Share button is on the toolbar, it will also be hidden. Policy options mapping: - ShareAllowed (0) = Allow using the Share experience. - ShareDisallowed (1) = Do not allow using the Share experience.
SRG-APP-000141
1 Rule
Guest mode must be disabled.
Medium Severity
Enabling Guest mode allows the use of guest profiles in Microsoft Edge. In a guest profile, the browser does not import browsing data from existing profiles, and it deletes browsing data when all guest profiles are closed. If this policy is enabled or not configured, Microsoft Edge lets users browse in guest profiles. If this policy is disabled, Microsoft Edge does not let users browse in guest profiles.
SRG-APP-000156
1 Rule
Relaunch notification must be required.
Medium Severity
Users must be required to restart the browser to finish installation of pending updates and prevent users from continually using an old/vulnerable browser version.
SRG-APP-000157
1 Rule
The built-in DNS client must be disabled.
Medium Severity
This setting controls whether to use the built-in DNS client. This does not affect which DNS servers are used; it only controls the software stack that is used to communicate with them. For example, if the operating system is configured to use an enterprise DNS server, that same server would be used by the built-in DNS client. However, it is however possible that the built-in DNS client will address servers in different ways by using more modern DNS-related protocols such as DNS-over-TLS. If this policy is enabled, the built-in DNS client is used if it is available. If this policy is disabled, the client is never used.
SRG-APP-000141
1 Rule
Use of the QUIC protocol must be disabled.
Medium Severity
QUIC is used by more than half of all connections from the Edge web browser to Google's servers, and this activity is undesirable in the DoD. If you enable this policy or don't configure it, the QUIC protocol is allowed. If you disable this policy, the QUIC protocol is blocked.
SRG-APP-000141
1 Rule
The list of domains media autoplay allows must be allowlisted if used.
Low Severity
Define a list of sites, based on URL patterns, that are allowed to autoplay media. If this policy is not configured, the global default value from the AutoplayAllowed policy (if set) or the user's personal configuration is used for all sites. EDGE-00-000024 disables the AutoplayAllowed policy.
SRG-APP-000141
1 Rule
Visual Search must be disabled.
Medium Severity
Visual Search allows for quick exploration of more related content about entities in an image. If this policy is enabled or not configured, Visual Search will be enabled via image hover, context menu, and search in Sidebar. If this policy is disabled, Visual Search will be disabled and more information about images will not be available via hover, context menu, and search in Sidebar.
SRG-APP-000141
1 Rule
Copilot must be disabled.
Medium Severity
The Sidebar is a launcher bar on the right side of Microsoft Edge's screen. If this policy is enabled or not configured, the Sidebar will be shown. If this policy is disabled, the Sidebar will never be shown. Disabling Sidebar will disable Copilot.
SRG-APP-000080
1 Rule
Session only-based cookies must be enabled.
Medium Severity
Cookies must only be allowed per session and only for approved URLs as permanently stored cookies can be used for malicious intent. Approved URLs may be allowlisted via the "CookiesAllowedForUrls" or "SaveCookiesOnExit" policy settings, but these are not requirements.
SRG-APP-000141
1 Rule
FriendlyURLs must be disabled.
Medium Severity
If FriendlyURLs are enabled, Microsoft Edge will compute additional representations of the URL and place them on the clipboard. This policy configures what format will be pasted when the user pastes in external applications, or inside Microsoft Edge without the "Paste As" context menu item. If configured, this policy makes a choice on behalf of the user. The options in edge://settings/shareCopyPaste will be grayed out, and the options in the "Paste As" context menu will not be available. Not configured = The user will be able to choose their preferred paste format. By default, this is set to the friendly URL format. The "Paste As" menu will be available in Microsoft Edge. 1 = No additional formats will be stored on the clipboard. There will be no "Paste as" context menu item in Microsoft Edge and the only format available to paste will be the plain text URL format. Effectively, the friendly URL feature will be disabled. 3 = The user will get a friendly URL whenever they paste into surfaces that accept rich text. The plain URL will still be available for non-rich surfaces. There will be no "Paste As" menu in Microsoft Edge. 4 = (Not currently used) The richer formats may not be well-supported in some paste destinations and/or websites. In these scenarios, the plain URL option is recommended when configuring this policy. The recommended policy is available in Microsoft Edge 105 or later. Policy options mapping: PlainText (1) = The plain URL without any extra information, such as the page's title. This is the recommended option when this policy is configured. For more information, see the description. TitledHyperlink (3) = Titled Hyperlink: A hyperlink that points to the copied URL, but whose visible text is the title of the destination page. This is the Friendly URL format.
SRG-APP-000039
1 Rule
User control of proxy settings must be disabled.
Low Severity
This action configures the proxy settings for Microsoft Edge. If this policy is enabled, Microsoft Edge ignores all proxy-related options specified from the command line. If this policy is not configured, users can choose their own proxy settings. This policy overrides the following individual policies: - ProxyMode - ProxyPacUrl - ProxyServer - ProxyBypassList Setting the ProxySettings policy accepts the following fields: - ProxyMode, which allows for the proxy server used by Microsoft Edge to be specified and prevents users from changing proxy settings. - ProxyPacUrl, a URL to a proxy .pac file. - ProxyServer, a URL for the proxy server. - ProxyBypassList, a list of proxy hosts that Microsoft Edge bypasses. For ProxyMode, the following values have the noted impact: - direct, a proxy is never used and all other fields are ignored. - system, the system's proxy is used and all other fields are ignored. - auto_detect, all other fields are ignored. - fixed_servers, the ProxyServer and ProxyBypassList fields are used. - pac_script, the ProxyPacUrl and ProxyBypassList fields are used.
