Introduction to DSPM for AI In an age where Artificial Intelligence (AI) is rapidly transforming industries, ensuring the security and compliance of AI integrations is paramount. Microsoft Purview Data Security Posture Management (DSPM) for AI helps organizations monitor AI activity, enforce security policies, and prevent unauthorised data exposure. Microsoft Purview Data Security Posture Management (DSPM) for AI addresses three primary areas: Recommendations, Reports, and Data Assessments. DSPM for AI assists in identifying vulnerabilities associated with unprotected data and enables prompt action to enhance data security posture and mitigate risks effectively. Getting Started with DSPM for AI To manage and mitigate AI-related risks, Microsoft Purview provides easy-to-use graphical tools and comprehensive reports. These features allow you to quickly gain insights into AI use within your organization. The one-click policies offered by Microsoft Purview simplify the process of protecting your data and ensuring compliance with regulatory requirements. Prerequisites for Data Security Posture Management for AI To use DSPM for AI from the Microsoft Purview portal or the Microsoft Purview compliance portal, you must have the following prerequisites: You have the right permissions. Monitoring Copilot interactions requires: Users are assigned a license for Microsoft 365 Copilot. o Microsoft Purview auditing enabled. Check instructions for Turn auditing on or off. Required for monitoring interactions with third-party generative AI sites: Devices are onboarded to Microsoft Purview, required for: Gaining visibility into sensitive information that's shared with third-party generative AI sites. (e.g., credit card numbers pasted into ChatGPT). Applying endpoint DLP policies to warn or block users from sharing sensitive information with third-party generative AI sites. (e.g. a user identified as elevated risk in Adaptive Protection is blocked with the option to override when they paste credit card numbers into ChatGPT) The Microsoft Purview browser extension is deployed to users and required to discover site visits to third-party generative AI sites. Things to consider Recommendations may differ based on M365 licenses and features. Not all recommendations are relevant for every tenant and can be dismissed. Any default policies created while Data Security Posture Management for AI was in preview and named Microsoft Purview AI Hub won't be changed. For example, policy names will retain their Microsoft AI Hub -prefix. In this blog post we are going to focus on Recommendations. Recommendations Let's explore each of the recommendations in detail, which will encompass one-click policy creation, data assessments, step-by-step guidance, and regulations. The data in the reports section will be contingent upon the completion of each recommendation.

Set Up Endpoint DLP Evidence Collection on your Azure Blob Storage
Endpoint Data Loss Prevention (Endpoint DLP) is part of the Microsoft Purview Data Loss Prevention (DLP) suite of features you can use to discover and protect sensitive items across Microsoft 365 services. Microsoft Endpoint DLP allows you to detect and protect sensitive content across onboarded Windows 10, Windows 11 and macOS devices. Learn more about all of Microsoft's DLP offerings. Before you start setting up the storage, you should review Get started with collecting files that match data loss prevention policies from devices | Microsoft Learn to understand the licensing, permissions, device onboarding and your requirements. Prerequisites Before you begin, ensure the following prerequisites are met: You have an active Azure subscription. You have the necessary permissions to create and configure resources in Azure. You have setup endpoint Data Loss Prevention policy on your devices Configure the Azure Blob Storage You can follow these steps to create an Azure Blob Storage using the Azure portal. For other methods refer to Create a storage account - Azure Storage | Microsoft Learn Sign in to the Azure Storage Accounts with your account credentials. Click on + Create On the Basics tab, provide the essential information for your storage account. After you complete the Basics tab, you can choose to further customize your new storage account, or you accept the default options and proceed. Learn more about azure storage account properties Once you have provided all the information click on the Networking tab. In network access, select Enable public access from all networks while creating the storage account. Click on Review + create to validate the settings. Once the validation passes, click on Create to create the storage Wait for deployment of the resource to be completed and then click on Go to resource. Once the newly created Blob Storage is opened, on the left panel click on Data Storage -> Containers Click on + Containers. Provide the name and other details and then click on Create Once your container is successfully created, click on it. Assign relevant permissions to the Azure Blob Storage Once the container is created, using Microsoft Entra authorization, you must configure two sets of permissions (role groups) on it: One for the administrators and investigators so they can view and manage evidence One for users who need to upload items to Azure from their devices Best practice is to enforce least privilege for all users, regardless of role. By enforcing least privilege, you ensure that user permissions are limited to only those permissions necessary for their role. We will use portal to create these custom roles. Learn more about custom roles in Azure RBAC Open the container and in the left panel click on Access Control (IAM) Click on the Roles tab. It will open a list of all available roles. Open context menu of Owner role using ellipsis button (…) and click on Clone. Now you can create a custom role. Click on Start from scratch. We have to create two new custom roles. Based on the role you are creating enter basic details like name and description and then click on JSON tab. JSON tab gives you the details of the custom role including the permissions added to that role. For owner role JSON looks like this: Now edit these permissions and replace them with permissions required based on the role: Investigator Role: Copy the permissions available at Permissions on Azure blob for administrators and investigators and paste it in the JSON section. User Role: Copy the permissions available at Permissions on Azure blob for usersand paste it in the JSON section. Once you have created these two new roles, we will assign these roles to relevant users. Click on Role Assignments tab, then on Add + and on Add role assignment. Search for the role and click on it. Then click on Members tab Click on + Select Members. Add the users or user groups you want to add for that role and click on Select Investigator role – Assign this role to users who are administrators and investigators so they can view and manage evidence User role – Assign this role to users who will be under the scope of the DLP policy and from whose devices items will be uploaded to the storage Once you have added the users click on Review+Assign to save the changes. Now we can add this storage to DLP policy. For more information on configuring the Azure Blob Storage access, refer to these articles: How to authorize access to blob data in the Azure portal Assign share-level permissions. Configure storage in your DLP policy Once you have configured the required permissions on the Azure Blob Storage, we will add the storage to DLP endpoint settings. Learn more about configuring DLP policy Open the storage you want to use. In left panel click on Data Storage -> Containers. Then select the container you want to add to DLP settings. Click on the Context Menu (… button) and then Container Properties. Copy the URL Open the Data Loss Prevention Settings. Click on Endpoint Settings and then on Setup evidence collection for file activities on devices. Select Customer Managed Storage option and then click on Add Storage Give the storage name and copy the container URL we copied. Then click on Save. Storage will be added to the list. Storage will be added to the list for use in the policy configuration. You can add up to 10 URLs Now open the DLP endpoint policy configuration for which you want to collect the evidence. Configure your policy using these settings: Make sure that Devices is selected in the location. In Incident reports, toggle Send an alert to admins when a rule match occurs to On. In Incident reports, select Collect original file as evidence for all selected file activities on Endpoint. Select the storage account you want to collect the evidence in for that rule using the dropdown menu. The dropdown menu shows the list of storages configured in the endpoint DLP settings. Select the activities for which you want to copy matched items to Azure storage Save the changes Please reach out to the support team if you face any issues. We hope this guide is helpful and we look forward to your feedback. Thank you, Microsoft Purview Data Loss Prevention Team
Onboarding Devices: "No authenticated user found"
Hi, I am looking to onboard a device in Purview for the purpose of testing some Endpoint DLP policies. I have ran the onboarding script locally and the device successfully appears on the 'Devices' screen. 'Real time protection/RTP' and 'Behavior monitoring/BM' both show as 'enabled' with a green tick, however under 'Valid User' it has a red cross and states: "Invalid: No authenticated user found. Without proper authentication, data classification is impeded. To ensure precise validation, we recommend re-onboarding to Active Directory". The device is in active directory. I have signed into the device with an account that is also in Active Directory. Is there anything additional that I need to do? Any help would be really appreciated - thank you!!!Real Time Monitoring and Behavior Monitoring
Good afternoon, I am running into an issue with DLP protecting endpoints, the following are the findings: In purview: - Real-Time Monitoring Enabled - Behavior Monitoring Enabled The devices are using CrowdStrike as the active AV client and the Defender AV client is in EDR Block Mode however when testing Policies that should restrict USB, Printing, and Copy and Paste of Sensitive Data the policies are not being enforced. The test device is not generating any alerts or notifications in the Purview portal or Toast Notifications. Policies are enforced via GPO: - Real Time Monitoring - Behavior Monitoring Endpoints have Windows Defender FW and Crowdstrike enabled, but have been disabled on the test device. Any insights on why the devices are showing in the MDE Portal that RTM and BM are disabled
Upload to a restricted cloud service domain or access from an unallowed browser
-The action in DLP rules "Upload to a restricted cloud service domain or access from an unallowed browser" does not seem to be working as expected. -Currently a number of policies are meant to detect certain sensitivity labels as well as certain information types and among the actions taken to restrict data/files being shared, Is the action named above. -The activity explorer shows the policy match but the enforcement action is always audit instead of block(which is specified in the policy) -Service domains and domain groups are added with an action of block in DLP settings. -Unallowed browser also specified. What could be the issue here? Any Ideas?exclude network share
i have enabled network share coverage and exclusions within the dlp settings and i have added a network share path in the exclusion list with the following format \\10.10.10.10\ i'm still getting alerts for file copied to network share activity, am i doing it right? do i need to be more specific? the file server has multiple directories and folders, i want to exclude all
