Advanced Hunting Custom detection rule notification cannot be customized
Hello, We have a case with both Microsoft and US cloud about the custom detection rule created by a query. The problem that we have is that I want to send the rule's notification to an email group. However, after about 2 months of investigations, I was advised below: "We can go one of two routes. Either the alerts from Defender can be ingested into sentinel based on the custom detection rule you created, or the Entra Sign-in logs can be ingested allowing Sentinel to check the logs itself." Could you please help us find an easier solution for the notification or create a feature request so that we could have the configuration of notification for custom detection rules when creating the alert?
Disable Defender for Cloud Apps alerts
Hi all, we just enabled Defender for Cloud Apps in our environment (about 500 clients). We started with setting about 300 apps to "Unsanctioned". Now we get flooded with alerts. Mainly "Connection to a custom network indicator on one endpoint" and "Multi-stage incident on multiple endpoints" when an URL is blocked on more clients. Is there a possibility to disable the alerts for this kind of blocks? I tried creating a supression rules, but didnt manage to get it working. Dont know if it is not possible or if I made a mistake. As the Defender for Cloud Apps just creates a Indicator for every app i want to block I could click every single Indicator and disable the alert there. But thats a few hundred Indicators and we plan to extend the usage. Can I centrally disable alerts for custom indicators? Thanks & Cheers
Unable 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?
Lack of alerts in Sentinel
Hello, I am troubleshooting a lack of alerts and incidents in my Sentinel deployment. When I look at the Micrsoft Defender XDR connector, I see plenty of events like DeviceEvents, DeviceInfo, IdentityLogonEvents, etc. However, the entries for: SecurityIncident-- SecurityAlert-- AlertInfo-- AlertEvidence-- all show grey with a disconnected connector showing. I've been over the onboarding documentation several times and can't find what I'm missing. Has anyone else experienced this who can point me in the right direction of what to check? Thanks!Defender not detecting test Kali Linux devices connected to network
Hello, first time posting here. Our organization is trying to get more familiar with MS 365 Defender. Just to see what it would discover, we connected a device running Kali Linux (not domain joined) to our internal LAN network then did some NMAP scans from it against the subnet and one of our servers. We were thinking we would see Defender trigger some kind of alert but that did not happen. We are also not seeing this Kali Linux device in the Defender Device Inventory anywhere. We have our device discovery set to Standard and have the appropriate networks enabled for Monitoring. Should we be getting some kind of alert of a non-onboarded device doing port scans against other devices in our network?Cannot use union * for Defender Hunting query to Create Detection Rule, so what other workarounds?
I tried to create custom detection rule from KQL query in Defender XDR: Advance Hunting by custom various variable to be able to submit, but for this query to be able to go through remediation setting of detection rule, I need the entity identifiable columns like AccountUpn, that I need to union with IdentityInfo schema. But detection rule seems not support the union * thing as the attached pic: I searched for the same problems that seems to be occurred in all system using KQL including in Microsoft Sentinel Logs but has no workaround to bypass. So, is there any way to get through this objective without strucking with union * problem?How to use KQL to associate alerts with incidents?
There is no method I'm aware of to use KQL to query from an alertID to an incident or vice versa. Please provide kql examples for querying between XDR incidents and alerts. These queries should be independent of the SecurityIncident table which is only available when Sentinel is connected to XDR. Thank you.
Microsoft Defender for cloud and XDR integration
🚨 Need Help! 🚨 I’m currently facing a challenge with Microsoft Defender for Cloud. I’ve created sample alerts, but when I check in Microsoft Defender XDR, the alerts aren’t showing up. 😕 I’ve already checked all possible configurations, permissions, and integration settings but haven’t been able to pinpoint the cause. Has anyone experienced something similar? Any suggestions on additional things to check or troubleshooting steps that might help resolve this? I was following a Udemy instructor’s video tutorial from 2024, where it worked fine for him, but unfortunately, it didn’t work for me.
How does Defender detect file version limit default changes?
Hi all, I am currently reviewing a historic article that mentions a Cloud Ransomware attack where attackers can change the default number of file versions saved by default. They change this from the default 500 to 1 and then save over your files to make them unrecoverable. Apparently this doesn't need admin credentials, a standard user can do this themselves. All of the Microsoft guidance says that Microsoft is protected against cloud ransomware attacks of this type because of the file versioning feature, as well as being able to contact Microsoft for 14 days after such an incident and they can retrieve your data. My questions are: Where do I find what the current settings are for file version limit defaults? Is it in the OneDrive/SharePoint admin centres? How do I find out whether such a change has been made? Is there an alert already configured in Defender to detect such a change? If not, does anyone know how to set one up, e.g., KQL and a custom detection? I tried asking Copilot, but it just sends me to the official Microsoft documentation, so any help is greatly appreciated.
