74 TopicsHow to stop incidents merging under new incident (MultiStage) in defender.
Dear All We are experiencing a challenge with the integration between Microsoft Sentinel and the Defender portal where multiple custom rule alerts and analytic rule incidents are being automatically merged into a single incident named "Multistage." This automatic incident merging affects the granularity and context of our investigations, especially for important custom use cases such as specific admin activities and differentiated analytic logic. Key concerns include: Custom rule alerts from Sentinel merging undesirably into a single "Multistage" incident in Defender, causing loss of incident-specific investigation value. Analytic rules arising from different data sources and detection logic are merged, although they represent distinct security events needing separate attention. Customers require and depend on distinct, non-merged incidents for custom use cases, and the current incident correlation and merging behavior undermines this requirement. We understand that Defender’s incident correlation engine merges incidents based on overlapping entities, timelines, and behaviors but would like guidance or configuration best practices to disable or minimize this automatic merging behavior for our custom and analytic rule incidents. Our goal is to maintain independent incidents corresponding exactly to our custom alerts so that hunting, triage, and response workflows remain precise and actionable. Any recommendations or advanced configuration options to achieve this separation would be greatly appreciated. Thank you for your assistance.

Hi, I am exploring XDR advanced hunting API to fetch data specific to Microsoft Defender for Endpoint tenants. The official documentation (https://learn.microsoft.com/en-us/defender-xdr/api-advanced-hunting) mentions to switch to Microsoft Graph advanced hunting API. I had below questions related to it: 1. To fetch the region specific(US , China, Global) token and Microsoft Graph service root endpoints(https://learn.microsoft.com/en-us/graph/deployments#app-registration-and-token-service-root-endpoints ) , is the recommended way to fetch the OpenID configuration document (https://learn.microsoft.com/en-us/entra/identity-platform/v2-protocols-oidc#fetch-the-openid-configuration-document) for a tenant ID and based on the response, the region specific SERVICE/TOKEN endpoints could be fetched? Since using it, there is no need to maintain different end points for tenants in different regions. And do we use the global service URL https://login.microsoftonline.com to fetch OpenID config document for a tenantID in any region? 2. As per the documentation, Microsoft Graph Advanced hunting API is not supported in China region (https://learn.microsoft.com/en-us/graph/api/security-security-runhuntingquery?view=graph-rest-1.0&tabs=http). In this case, is it recommended to use Microsoft XDR Advanced hunting APIs(https://learn.microsoft.com/en-us/defender-xdr/api-advanced-hunting) to support all region tenants(China, US, Global)?129Views0likes1CommentDefender is missing logs for files copied to USB device on Mac devices
Hello, I am currently facing an issue with Defender not logging files copied to USBs. Using the KQL below, I can only see .exe files copied, but nothing when it comes to .pdf, .docx. .zip and other standard file extensions. Has someone come across this issue before? Any help is greatly appreciated let UsbDriveMount = DeviceEvents | where ActionType=="UsbDriveMounted" | extend ParsedFields=parse_json(AdditionalFields) | project DeviceId, DeviceName, DriveLetter=ParsedFields.DriveLetter, MountTime=TimeGenerated, ProductName=ParsedFields.ProductName,SerialNumber=ParsedFields.SerialNumber,Manufacturer=ParsedFields.Manufacturer | order by DeviceId asc, MountTime desc; let FileCreation = DeviceFileEvents | where InitiatingProcessAccountName != "system" | where ActionType == "FileCreated" | where FolderPath !startswith "C:\\" | where FolderPath !startswith "\\" | project ReportId,DeviceId,InitiatingProcessAccountDomain, InitiatingProcessAccountName,InitiatingProcessAccountUpn, FileName, FolderPath, SHA256, TimeGenerated, SensitivityLabel, IsAzureInfoProtectionApplied | order by DeviceId asc, TimeGenerated desc; FileCreation | lookup kind=inner (UsbDriveMount) on DeviceId | where FolderPath startswith DriveLetter | where TimeGenerated >= MountTime | partition hint.strategy=native by ReportId ( top 1 by MountTime ) | order by DeviceId asc, TimeGenerated desc | extend HostName = iff(DeviceName has '.', substring(DeviceName, 0, indexof(DeviceName, '.')), DeviceName) | extend DnsDomain = iff(DeviceName has '.', substring(DeviceName, indexof(DeviceName, '.') + 1), "") | extend FileHashAlgorithm = 'SHA256'Solved110Views0likes2CommentsFirewall Rules programming with Defender XDR
We have our devices onboarded to Defender for Endpoint, and want to program Firewall Policy and Firewall Rules Policy using Defender Onboarding. We know that we can onboard devices to Intune and use Intune MDM to program rules. But, we don't want a full blown MDM setup or license for just firewall programming. Is there a deployment scenario where we can do firewall programming just using defender machines. Any help is really appreciated.Solved277Views0likes1CommentUnable to add Endpoints and Vulnerability management in XDR Permissions
Hi, I have defender for endpoint running on obver 400 devices. I have 10 with Bus Premium, 5 with E5, and the rest E3. I am getting incidents for DFE, and this is being sent to my SOAR platform for analysis, but when I pivot back using client-sync, I cannot see DFE incidents. I have gone into Settings > XDR > Workload settings, and can only see the below There does not appear to be the option to grant the roles I have provided for my SOAR user the ability to see Endpoint and Vulnerability management. Really scratching my head here. Help?321Views0likes3CommentsHow to Connect MS Secure Scores to Power Query?
The Microsoft 365 Defender Portal (https://security.microsoft.com/) has a 'Secure Score' page, which contains the following: An overall secure score which is then broken down by Identity, Data, Device, and Application secure scores. I would like to be able to pull these four scores into a Power BI report; however, I have had some difficulty in putting together a solution. This data seems like it could be found in the Microsoft Graph API, but https://learn.microsoft.com/en-us/power-query/connecting-to-graph. I've tried other Defender APIs, but they all seem either outdated or out of scope for what I'm trying to pull. Can anyone advise? Thanks for reading.2.8KViews0likes2CommentsAre critical asset management rules incompatible with Entra ID?
I am trying to create some custom asset management rules based on filters like logged on username, user criticality, and user groups. No matter what I try no assets show up. Even if I use the format azuread\<username>, no assets are returned by the filter. Are these filters incompatible with Entra ID? Do they only work with on-premise AD?188Views0likes4CommentsFull Automation Capabilities in Linux OS
Hello eveyone, We have configured Defender to detect viruses, and our goal is that if one of our assets downloads or encounters a virus, it is automatically hidden or removed. Based on the documentation regarding the automation levels in Automated Investigation and Remediation capabilities, we have set it to "Full - remediate threats automatically." While this works correctly on Windows devices, we have noticed that on Linux devices, the defender still detect the virus but it was not prevented. I was wondering if anyone has encountered this issue and, if so, how it was resolved? Additionally, as I am new to the Defender platform, I wanted to ask if could this issue potentially be resolved through specific Linux policies or functionalities?

Good afternoon, I need some help setting up a KQL query in Advanced Hunting along with a Custom Detection Rule to automatically isolate devices where a virus or ransomware is detected. The rule must run at NRT (Near Real-Time) frequency. We are using Microsoft Defender for Business, which is included in the Microsoft 365 Business Premium license. Would any kind community member be able to provide me with a starting point for this? Thank you in advance!Solved593Views1like3Comments
