Ingesting Purview compliance DLP logs to Splunk
We are in the process of enabling Microsoft purview MIP DLP for a large-scale enterprise, and there is a requirement to push MIP DLP related alerts, incidents and data to Splunk SIEM. Could not find any specific documentation for the same. researched on this and found below solutions however not sure which could work to fit in our requirement: Splunk add on for Microsoft security is available: The Splunk Add-on for Microsoft Security is now available - Microsoft Community Hub but this does not talk about Purview DLP logs. This add-on is available for Splunk but only says MIP can be integrated however does not talk about DLP logs: Microsoft Graph Security API Add-On for Splunk | Splunkbase As per few articles we can also ingest Defender logs to Azure event hub then event hub can be connected to splunk. Above mentioned steps do not explain much about Ingestion of MIP DLP raw data or incidents. If anyone has done it in the past I will appreciate any input.
User app registration - exploitable for BEC?
Hello. Recently dealt with a case of BEC. I'm not trained in forensics, but doing my best. Appears the hacker used an application called eM Client for their attack, getting access to a user's mailbox and hijacking a thread. I can see the login from two weeks ago (the incident was only noticed a couple days ago, however) - from a European country that SHOULD have been blocked by Conditional Access. Come to find out, the tenant conditional access was unassigned from everyone. We're not sure how - we re-enabled it, and audited changes, but the only change that appears was us re-enabling it. Which I thought indicates it was never configured right, except we've got a ticket documenting a change to Conditional Access a couple days after the hack that ALSO does not appear in the logs. So... it's likely it was changed, yet I have no record of that change (atleast, not through Entra > Monitoring > Auditing). If anyone knows any other ways of checking this, please advise - but I can't seem to even access our Diagnostic settings, the page tells me I need an Azure Active Directory subscription (I'm on Entra ID P1, which includes AAD.... this might be related to being global admin, and not Security Admin - we don't use that role in this relationship) ANYWAY, my amateur forensic skills have found that the attacker used an app called eM Client to get access. I'm not sure yet how they obtained the password, and got past MFA... But quick research shows this application (esp it's pro version) is known for use in BEC. The app was registered in Entra, and granted certain read permissions in Entra ID for shared mailboxes, presumably to find a decent thread to hijack. I'm not 100% sure yet there was any actual exploit done using this app, but it's popularity amongst hackers implies it does SOMETHING useful (i think remember that it authenticates using Exchange Web Services instead of Exchange Online, or something similar? Will update when I have the chance to check). We're in the process of improving our Secure Score, and this incident makes me think user's ability to register apps should be locked down. Checked Secure Score for this, and while there ARE recommendations around apps, disabling user app registration is NOT one of them. Just curious about people's thoughts. I just barely understand App Registration in Entra, but if this is a known attack vector, I would think disabling app registration would be a security recommendation?Programatically retrieve Secure Score Activities
Hi there, I am wondering if it is possible to retrieve a list of activities taken to increase/decrease a tenant's Secure Score. I can see that it is possible to export to CSV from the frontend, but we are looking to do this programatically. Is there a way to export these events to another Azure service, or retrieve them from the Graph API/another service?

How to configure Security Events collection with Azure Monitor Agent - Microsoft Community Hub Although Microsoft Defender for Servers (part of the Microsoft Defender for Cloud suite) does not rely on security events collection to provide its protection capabilities, customers may want to collect this valuable data to bring additional context to their server security investigations or alerts. For this reason, Defender for Servers Plan 2 users benefit from a 500-MB free data ingestion allowance (per day, per server) into Log Analytics, as long as the Defender for Servers Plan 2 is also enabled at the Log Analytics Workspace level. Security events collection (for Windows systems only) is done with the help of a guest agent. This has been possible so far with the legacy Log Analytics agent and the Defender for Servers auto-provisioning experience, and is also possible for Microsoft Sentinel users, via the Log Analytics and Azure Monitor Agent (AMA) data connectors. However, if you are not a Sentinel user yet and you are using Defender for Servers with the new AMA experience, it is still possible to collect security events, as you will learn next.

In Azure Active Directory, you can enable Diagnostic Settings, select Logs and configure them for archive in a Storage Account. In Azure Log Analytics, you can select Data Export, select Logs and configure them for archive in a Storage Account. Can someone describe the pros/cons/differences, right/wrong, when to use one over the other, how to decide which one to configure etc?
Audit logging for OneDrive - No records returned
Hi everyone, I'm runnning into some unexpected behaviour when running an Audit Log search in our tenant. The logging settings on both tenant level and OneDrive level are set to record actions, but the logging remains empty, across all users. Get-AdminAuditLogConfig | FL UnifiedAuditLogIngestionEnabled UnifiedAuditLogIngestionEnabled : True I am able to see audit log records for other platforms such as SharePoint and Azure, and I am Global Admin to our tenant. Does anyone know what my issue might be? Any help would be greatly appreciated! Cheers, Matthijs
