    You see a popup like this on the client device:

     This screenshot shows the endpoint dlp client blocked override notification.

  10. Check the activity explorer for the event.

Scenario 4: Avoid looping DLP notifications from cloud synchronization apps with autoquarantine

This scenario is for an unrestricted admin creating a full directory policy.

Before you begin Scenario 4

In this scenario, synchronizing files with the Highly Confidential sensitivity label to OneDrive is blocked. This is a complex scenario with multiple components and procedures. You need:

There are three procedures.

  1. Configure the Endpoint DLP Autoquarantine settings.
  2. Create a policy that blocks sensitive items that have the Highly Confidential sensitivity label.
  3. Create a Word document on the Windows 10/11 device that the policy is targeted to, apply the label, and copy it to the user accounts local OneDrive folder that is being synchronized.

Configure Endpoint DLP unallowed app and Autoquarantine settings

Select the appropriate tab for the portal you're using. To learn more about the Microsoft Purview portal, see Microsoft Purview portal. To learn more about the Compliance portal, see Microsoft Purview compliance portal.

C:\Users\IsaiahLanger\Microsoft DLP\Quarantine\OneDrive

  1. Append a date and time stamp to the original file name.

    Note

    DLP auto-quarantine will create sub-folders for the files for each unallowed app. So if you have both Notepad and OneDrive in your unallowed apps list, a sub-folder will be created for \OneDrive and another sub-folder for \Notepad.

  2. Choose Replace the files with a .txt file that contains the following text and enter the text you want in the placeholder file. For example for a file named auto quar 1.docx, you could enter:

    %%FileName%% contains sensitive info that your organization is protecting with the data loss prevention (DLP) policy %%PolicyName%%. It was moved to the quarantine folder: %%QuarantinePath%%

    will leave a text file that contains this message:

    auto quar 1.docx contains sensitive info that your organization is protecting with the data loss prevention (DLP) policy. It was moved to the quarantine folder: C:\Users\IsaiahLanger\Microsoft DLP\Quarantine\OneDrive\auto quar 1.docx.

  1. Sign in to the Windows 10/11 computer with the user account you specified in Configure a policy to block OneDrive synchronization of files with the sensitivity label Highly Confidential, step 5.

  2. Create a folder whose contents won't be synchronized to OneDrive. For example:

    C:\auto-quarantine source folder

  3. Open Microsoft Word and create a file in the autoquarantine source folder. Apply the Highly confidential sensitivity label; see Apply sensitivity labels to your files and email in Office.

  4. Copy the file you created to your OneDrive synchronization folder. A user notification toast should appear telling you that the action isn't allowed and that the file will be quarantined. For example, for user name Isaiah Langer, and a document titled autoquarantine doc 1.docx you would see this message:

    This screenshot shows the Data loss prevention user notification message that the OneDrive synchronization action isn't allowed for the specified file and that the file will be quarantined.

    The message reads:

    Opening auto-quarantine doc 1.docx with this app is not allowed. The file will be quarantined to 'C:\Users\IsaiahLanger\Microsoft DLP\OneDrive'

  5. Choose Dismiss.

  6. Open the place holder text file. It is named auto-quarantine doc 1.docx_date_time.txt.

  7. Open the quarantine folder and confirm that the original file is there.

  8. Check Activity explorer for data from the monitored endpoints. Set the location filter for devices and add the policy, then filter by policy name to see the effect of this policy. For information on using activity explorer, see Get started with activity explorer.

  9. Check Activity explorer for the event.

Scenario 5: Restrict unintentional sharing to unallowed cloud apps and services

This scenario is for an unrestricted admin creating a full directory policy.

With Endpoint DLP and a supported web browser, you can restrict unintentional sharing of sensitive items to unallowed cloud apps and services. Microsoft Edge understands when an item is restricted by an Endpoint DLP policy and enforces access restrictions.

Note

The following web browsers are supported:

  • Microsoft Edge
  • Chrome (with the Microsoft Purview extension for Chrome installed)
  • Firefox (with the Microsoft Purview extension for Firefox installed)

When you select Devices as a location in a properly configured DLP policy and use a supported web browser, the unallowed browsers that you've defined in these settings will be prevented from accessing the sensitive items that match your DLP policy controls. Instead, users are redirected to use Microsoft Edge, which, with its understanding of DLP imposed restrictions, can block or restrict activities when the conditions in the DLP policy are met.

To use this restriction, you need to configure three important pieces:

  1. Specify the places – services, domains, IP addresses – that you want to prevent sensitive items from being shared to.

  2. Add the browsers that aren’t allowed to access certain sensitive items when a DLP policy match occurs.

  3. Configure DLP policies to define the kinds of sensitive items for which upload should be restricted to these places by turning on Upload to cloud services and Access from unallowed browser.

You can continue to add new services, apps, and policies to extend and augment your restrictions to meet your business needs and protect sensitive data.

This configuration helps ensure your data remains safe while also avoiding unnecessary restrictions that prevent or restrict users from accessing and sharing nonsensitive items.

You can also audit, block with override, or block these user-upload sensitive items to cloud apps and services through Sensitive service domains.

Select the appropriate tab for the portal you're using. To learn more about the Microsoft Purview portal, see Microsoft Purview portal. To learn more about the Compliance portal, see Microsoft Purview compliance portal.

Scenario 7: Restrict pasting sensitive content into a browser

This scenario is for restricting users from pasting sensitive content into a browser web form or field on browsers including Microsoft Edge, Google Chrome (with the Microsoft Purview extension), and Mozilla Firefox (with the Microsoft Purview extension).

Important

If you have configured evidence collection for file activities on devices and your Antimalware Client Version on the device is older than 4.18.23110, when you implement this scenario, Restrict pasting sensitive content into a browser, you will see random characters when you attempt to view the source file in Alert details. To see the actual source file text, you should download the file.

Create your DLP policy

You can set up different levels of enforcement when it comes to blocking data from being pasted into a browser. To do this, create different URL groups. For instance, you can create a policy that warns users against posting U.S. Social Security Numbers (SSN) to any website, and that triggers an audit action for websites in Group A. You can create another policy that completely blocks the paste action--without giving a warning--for all of the websites in Group B.

Create a URL group

Select the appropriate tab for the portal you're using. To learn more about the Microsoft Purview portal, see Microsoft Purview portal. To learn more about the Compliance portal, see Microsoft Purview compliance portal.

Important

There may be a brief time lag between when the user attempts to paste text into a web page and when the system finishes classifying it and responds. If this classification latency happens, you may see both policy-evaluation and check-complete notifications in Edge or policy-evaluation toast on Chrome and Firefox. Here are some tips for minimizing the number of notifications:

  1. Notifications are triggered when policy for the target website is configured to Block or Block with override paste to browser for that user. You can configure setting the overall action to Audit and then list the target websites using the exceptions as Block. Alternately, you can set the overall action to Block and then list secure websites using the exceptions as Audit.
  2. Use latest Antimalware client version.
  3. Use latest Edge browser version, especially Edge 120.
  4. Install these Windows KBs

Scenario 8: Authorization groups

This scenario is for an unrestricted admin creating a full directory policy.

These scenarios require that you already have devices onboarded and reporting into Activity explorer. If you haven't onboarded devices yet, see Get started with Endpoint data loss prevention.

Authorization groups are mostly used as allowlists. You assigned policy actions to the group that are different than the global policy actions. In this scenario, we go through defining a printer group and then configuring a policy with block actions for all print activities except for the printers in the group. These procedures are essentially the same for Removeable storage device groups, and Network share groups.

In this scenario, we define a group of printers that the legal department uses for printing contracts. Printing contracts to any other printers is blocked.

This scenario is for an unrestricted admin creating a full directory policy.

This scenarios require that you already have devices onboarded and reporting into Activity explorer. If you haven't onboarded devices yet, see Get started with Endpoint data loss prevention.

In this scenario, we define a list of VPNs that hybrid workers use for accessing organization resources.

Create and use a Network exception

Network exceptions enable you to configure Allow, Audit only, Block with override, and Block actions to the file activities based on the network that users are accessing the file from. You can select from the VPN settings list you've defined and use the Corporate network option. The actions can be applied individually or collectively to these user activities:

  • Copy to clipboard
  • Copy to a USB removable device
  • Copy to a network share
  • Print
  • Copy or move using unallowed Bluetooth app
  • Copy or move using RDP

Get the Server address or Network address

  1. On a DLP monitored Windows device, open a Windows PowerShell window as an administrator.

  2. Run this cmdlet:

    Get-VpnConnection
    
  3. Running this cmdlet returns multiple fields and values.

  4. Find the ServerAddress field and record that value. You use this when you create a VPN entry in the VPN list.

  5. Find the Name field and record that value. The Name field maps to the Network address field when you create a VPN entry in the VPN list.

Determin if the device is connected through a Corporate network

  1. On a DLP monitored Windows device, open a Windows PowerShell window as an administrator.

  2. Run this cmdlet:

    Get-NetConnectionProfile
    
  3. If the NetworkCategory field is DomainAuthenticated, then the device is connected to a corporate network. If its anything else, the device's connection is not through a corporate network.
