Microsoft Purview | Share block at external users
Hello community. I have an issue with Microsoft Purview DLP policies. I am trying to create a policy that prevents documents from being shared through OneDrive with external users, while allowing certain exceptions. However, when I select the option "Block Access to external domains and users" and assign a specific email address to be blocked, it does not work. The configured email address is not being blocked. I was reviewing this with Copilot, and it mentioned that if the external user you are sharing with already exists in Entra ID, the tenant may treat the user differently (not necessarily as an external user). My external user exists in Entra ID as a Guest account. The external user is registered as follows: Displayname: User Name Userprincipalname: user.name_external.domain#EXT#@company.onmicrosoft.com User Type: Guest Has anyone else experienced this issue? I am sharing evidence of the policy configuration.
Insider Risk Level not being correctly picked up by DLP
I have two users currently with assigned Insider Risk levels, one elevated and one minor. I have taken the templated DLP policy (DSPM for AI - Block sensitive info from AI sites) which looks for sensitive information being pasted to generative AI sites, and applies a block if the user is an elevated risk user, and a block with override for a moderate/minor risk user (this was audit only originally). For each advanced DLP rule within that policy, I have a separate policy tip which shows so I know which Advanced DLP rule has been hit. However, I'm having some discrepancies with the correct insider risk level being identified by Purview and therefore the wrong advanced DLP rule is being applied. Testing examples: Logged into a Windows 11 PC with the account, and using Medium confidence UK NINO's I try pasting the content into ChatGPT: Elevated risk user: Block with Override Minor Risk user: Block with Override If I try the exact same scenario on a different PC, I can sometimes get to the point where even though its the same set of data, Purview allows me to paste it at after checking the data. Or in another scenario, I was getting both users hitting the "elevated risk" advanced DLP rule. The Devices are all showing as up to date sync wise with DLP policies, and the policy itself is showing as fully synced. Assigned insider risk levels: DLP Rules: Elevated: Moderate/Minor:
I just want to secure AI. DLP vs Info Protection vs DSPM vs Governance vs...
I'm with an MSP, and I've avoided Purview like the plague, because it seems to be suffering from the same 'made by marketing teams' 'strategy' the 365 documentation is. However, it's my understanding Purview policies are needed for Data control of Copilot. Here's my issue: all of these different 'solutions' sound like the exact same thing, but are pitched as if they are something different. i'm going to post a couple of descriptions for these 'solutions' to illustrate this. 'discover, label, and protect sensitive and business-critical info' 'make sure your organization can identify, monitor, and protect sensitive info across the expanding Microsoft 365 landscape' 'discover and secure all your sensitive data across Microsoft 365 and non-365 data sources' 'Discover, label, and protect sensitive and business-critical info across your multicloud data estate.' I genuinely do not have time to figure out what each of these 'solutions' are, then figure out their policies, then their giant library of settings (below)... It's not even clear to me what's active NOW, considering we never licensed Purview - but somehow have been roped into it. It SEEMS like these are all variations of marketing terms, which all point to 3-4 actual technical implementations in obscure ways. Can someone advise on the ACTUAL technical policies we want to target and enable? Or just give some clarity? I've never felt so overwhelmed or disconnected from Microsoft's environment. We just want to secure our tenant's AI usage.
Purview SDK
I've been spending quite a bit of time working with Purview APIs, The APIs themselves are fine, but after a while I realized I was writing the same authentication, pagination and relationship handling code over and over again. So instead of construction the same code from project to project, I turned it into a python package, and now it's available on PyPI pip install purview-unified-sdk Right now, the SDK supports most of the common operations, such as creating, retrieving, updating and deleting business domains, data products, glossary terms, objectives, key results and etc., It also make it much easier to work with relationships, add group id as a owner, navigate resources and retrieve metadata across the unified catalog. https://niki9001.github.io/purview-unified-sdk/ https://github.com/purview-unified-sdk Feel free to fork the project, submit a pull request or open an issue if you have ideas or suggestionsMissing activity names from Audit Log documentation
We all know that the documentation team is A-tier and amazing at what they do and isn't just copy and pasting marketing materials. But I've noticed that some really obscure functionalities like 'user registered a device' or 'user joined a device' or about half the other things a user can do, are not documented on this list of activity names. The ironically named 'friendly' list doesn't work. So I actually can't audit the unfamiliar devices under our tenants? It appears that this KB is actually locked down, so more can't be added when they are discovered. How are we supposed to use the tool Microsoft has forced everyone towards, when the Documentation team is too bad to document anything, so they outsource it to the community (Microsoft victims), but then they lock down contributions (presumably, because they have some metric that keeps them from being useful - atleast based on my interactions with them). Documentation seems to be a massive fail on Microsoft's part. How did it get this way? Is there a reliable way of finding the activity name - one that ISN'T some preview Graph endpoint that I can't teach my techs to use, because I'm not teaching my techs to program?
Onboarding Devices to Purview
I am not clear on how can I onboard devices to MDE so that I can enforce EDLP policies. We have CrowdStrike as Primary AV and other policies. Devices are managed through Intune for Bitlocker encryption and all the other settings except they don't have Defender. These devices are not showing up in Purview nor under "Endpoint detection and response" location under Endpoint Security. If we create an EDR onboarding policy and deploy to devices, then it shows the devices and says that AMRUnningMode is Passive, but Antivirus is true. Which I feel like Defender is taking over CrowdStrike? or am I wrong. My goal is to make sure CrowdStrike still primary AV and devices should be onboarded to MDE and then to Purview so that we can scope EDLP policies properly. Can anyone help me to understand or provide right steps?Confusion around Purview Definitions and Risk Scoring
In the early days of implementation and we've done our 'Quick setup' of Insider Risk Management which created our Adaptive Protection Policy for IRM, two IRM DLP policies (Endpoint & Teams/Exchange) and the Conditional Access policy. My question is around 'Triggering events', Indicators and Insider Risk Levels. To my understanding, a triggering event is the event that decides when the policy will start assigning risk scores to user activity which will then allow us to then give users risk levels. We have the option to either set this triggering event to either the DLP policies, or when a user performs an exfiltration activity/ sequence. The DLP policies only match activity when a user has a defined risk level and attempts to perform a specific activity i.e. sharing M365 with people outside the organisation. I'm not sure if I'm thinking about this backwards, but if I set my Adaptive protection policy to only start assigning risk scores to user activity when they match a DLP policy, how can they trigger a DLP policy if they wont be assigned a risk level until that scoring begins to happen? Should I be setting my triggering events to be "User performs an Exfiltration Activity" instead of "User Matches a DLP policy"?Anthropic Claude Purview Data Connector showing all users as Guests..
It appears this connector is not mapping fields properly causing internal users to be mapped as "guests", and since prompts/data isn't maintained for guest users the connector is effectively not gathering anything but noise. Unlike the other data connectors, one cannot create field mappings. Also the app being named using the guid of Microsoft's own "dataassessments" service principal I don't think is intended either. Has anybody else experienced this? See below for an example.
Co Authoring with Sensitivity Labels
Hello, I am working with sensitivity labels with my organization. We currently have Standard, Confidential, and Highly Confidential which all are encrypted. I have Co-Authoring turned on but I have some trouble with. We a lot of documents being collaborated on. Standard: Co-Authoring functions normal and Auto-Save is toggled on. Highly Confidential: Custom Permission in Sensitivity Label (View, Edit, Reply, Forward) I asked copilot and it stated even though my permissions are selected custom I have "Edit" on their for my internal users it is reading it as Co authoring; Co-Authoring is on and functioning but internal end users Auto-Save is toggled off and they are being asked to save a copy of the document or excel sheet then upload it again to SharePoint. Why isn't "Auto-Save" toggled on for "Highly Confidential" label? Can it be adjusted so it can be on? Do I have to make adjustments to my permissions in the Sensitivity label? Any help is appreciated. Thank you!
