App and browser isolation profile

Note

This section details the settings in App and browser isolation profiles created before April 18, 2023. Profiles created after that date use a new settings format as found in the Settings Catalog. With this change you can no longer create new versions of the old profile and they are no longer being developed. Although you can no longer create new instances of the older profile, you can continue to edit and use instances of it that you previously created.

For profiles that use the new settings format, Intune no longer maintains a list of each setting by name. Instead, the name of each setting, its configuration options, and its explanatory text you see in the Microsoft Intune admin center are taken directly from the settings authoritative content. That content can provide more information about the use of the setting in its proper context. When viewing a settings information text, you can use its Learn more link to open that content.

App and browser isolation

  • Turn on Application Guard
    CSP: AllowWindowsDefenderApplicationGuard

    • Not configured (default) - Microsoft Defender Application Guard isn't configured for Microsoft Edge or isolated Windows environments.
    • Enabled for Edge - Application Guard opens unapproved sites in a Hyper-V virtualized browsing container.
    • Enabled for isolated Windows environments - Application Guard is turned on for any applications enabled for App Guard within Windows.
    • Enabled for Edge AND isolated Windows environments - Application Guard is configured for both scenarios.

    Note

    If you are deploying Application Guard for Microsoft Edge via Intune, Windows network isolation policy must be configured as a prerequisite. Network isolation may be configured via various profiles, including App and broswer isolation under the Windows network isolation setting.

    When set to Enabled for Edge or Enabled for Edge AND isolated Windows environments, the following settings are available, which apply to Edge:

    • Clipboard behavior
      CSP: ClipboardSettings

      Choose what copy and paste actions are allowed from the local PC and an Application Guard virtual browser.

      • Not configured (default)
      • Block copy and paste between PC and browser
      • Allow copy and paste from browser to PC only
      • Allow copy and paste from PC to browser only

      CSP: AllowVirtualGPU

      • Not configured (default)
      • Yes - Within the Application Guard virtual browsing session, use a virtual graphics processing unit to load graphics-intensive websites faster.

      CSP: SaveFilesToHost

      • Not configured (default)
      • Yes - Allow users to download files from the virtualized browser onto the host operating system​.

    CSP: CertificateThumbprints

    Configure certificate thumbprints to automatically transfer the matching root certificate to the Microsoft Defender Application Guard container.

    To add thumbprints one at a time, select Add. You can use Import to specify a .CSV file that contains multiple thumbprint entries that are all added to the profile at the same time. When you use a .CSV file, each thumbprint must be separated by a comma. For example: b4e72779a8a362c860c36a6461f31e3aa7e58c14,1b1d49f06d2a697a544a1059bd59a7b058cda924

    All entries that are listed in the profile are active. You don't need to select a checkbox for a thumbprint entry to make it active. Instead, use the checkboxes to help you manage the entries that have been added to the profile. For example, you can select the checkbox of one or more certificate thumbprint entries and then Delete those entries from the profile with a single action.

  • Block persistence through WMI event subscription
    Reduce attack surfaces with attack surface reduction rules

    This attack surface reduction (ASR) rule is controlled via the following GUID: e6db77e5-3df2-4cf1-b95a-636979351e5b

    This rule prevents malware from abusing WMI to attain persistence on a device. Fileless threats employ various tactics to stay hidden, to avoid being seen in the file system, and to gain periodic execution control. Some threats can abuse the WMI repository and event model to stay hidden.

    • Not configured (default) – The setting returns to the Windows default, which is off and persistence isn't blocked.
    • Block – Persistence through WMI is blocked.
    • Audit – Evaluate how this rule affects your organization if it's enabled (set to Block).
    • Disable - Turn this rule off. Persistence is not blocked.

Device control profile

Device Control

Note

This section details the settings found in Device control profiles created before May 23, 2022. Profiles created after that date use a new settings format as found in the Settings Catalog. Although you can no longer create new instances of the original profile, you can continue to edit and use your existing profiles.

For profiles that use the new settings format, Intune no longer maintains a list of each setting by name. Instead, the name of each setting, its configuration options, and its explanatory text you see in the Microsoft Intune admin center are taken directly from the settings authoritative content. That content can provide more information about the use of the setting in its proper context. When viewing a settings information text, you can use its Learn more link to open that content.

    • Yes - block direct memory access (DMA) for all hot pluggable PCI downstream ports until a user logs into Windows. After a user logs in, Windows enumerates the PCI devices connected to the host plug PCI ports. Every time the user locks the machine, DMA is blocked on hot plug PCI ports with no children devices until the user logs in again. Devices that were already enumerated when the machine was unlocked will continue to function until unplugged.

  • Enumeration of external devices incompatible with Kernel DMA Protection
    CSP: DmaGuard/DeviceEnumerationPolicy

    This policy can provide additional security against external DMA capable devices. It allows for more control over the enumeration of external DMA capable devices incompatible with DMA Remapping/device memory isolation and sandboxing.

    This policy only takes effect when Kernel DMA Protection is supported and enabled by the system firmware. Kernel DMA Protection is a platform feature that must be supported by the system at the time of manufacturing. To check if the system supports Kernel DMA Protection, check the Kernel DMA Protection field in the Summary page of MSINFO32.exe.

Note

This section details the settings you can find in Exploit protection profiles created before April 5, 2022. Profiles created after that date use a new settings format as found in the Settings Catalog. With this change you can no longer create new versions of the old profile and they are no longer being developed. Although you can no longer create new instances of the older profile, you can continue to edit and use instances of it that you previously created.

For profiles that use the new settings format, Intune no longer maintains a list of each setting by name. Instead, the name of each setting, its configuration options, and its explanatory text you see in the Microsoft Intune admin center are taken directly from the settings authoritative content. That content can provide more information about the use of the setting in its proper context. When viewing a settings information text, you can use its Learn more link to open that content.

  • Upload XML
    CSP: ExploitProtectionSettings

    Enables the IT admin to push out a configuration representing the desired system and application mitigation options to all the devices in the organization. The configuration is represented by an XML file. Exploit protection can help protect devices from malware that use exploits to spread and infect. You use the Windows Security app or PowerShell to create a set of mitigations (known as a configuration). You can then export this configuration as an XML file and share it with multiple machines on your network so they all have the same set of mitigation settings. You can also convert and import an existing EMET configuration XML file into an exploit protection configuration XML.

    Choose Select XML File, specify the XML filet upload, and then click Select.
