"Duplicate" alerts in Defender for Cloud from MDE
Hello, I discovered that security alerts generated from Defender for Endpoint are causing "duplicate" security alerts in Defender for Cloud. We have several Azure Arc-enabled servers active with Defender for Server P1 which includes Defender for Endpoint integration. Hence Arc servers are automatically onboarded to Defender for Endpoint. We had a false positive caused by the addition of AV exclusions which generated an alert / incident in Defender XDR which was then synced to Sentinel. Closing the alerts in Defender XDR or Sentinel resulted in synced status between the two. However it seems the same alerts were also created in Defender for Cloud, and their status remained "open" even after being resolved in Defender XDR. The link in the open Defender for Cloud Alert effectively opens up the resolved alert in Defender XDR. So it seems to be the same alert but its status is not being synced. Is this a known issue?
Advanced Hunting Data Schema
Hello everyone, I have a question regarding the use of schema for Advanced Hunting queries. We are an organization with several companies under our holding. I need to recover the USB connections on the machines but only for one company and not the others. I need to sort on Company Name for the user. But in the Advanced Hunting schema there are no fields to filter on this. I looked specifically in UserInfo and DeviceInfo. Here's the query I use to detect USBs. I need to filter by CompanyName to retrieve the list of devices or users for this company only. DeviceEvents | where ActionType == “PnpDeviceConnected” | extend parsed=parse_json(AdditionalFields) | project Timestamp, DeviceName, DeviceId=tostring(parsed.DeviceId), ClassName=tostring(parsed.ClassName) | where ClassName == “DiskDrive” | summarize UsbFirstSeen=min(Timestamp), UsbLastSeen=max(Timestamp) by DeviceId, DeviceName; Is there another solution ? Thanks in advance for your answers, HKN
Deploying Defender for Business without o365 accounts
Hi, I have few SMB customers, who due to nature of their buiness do not want/need o365 accounts. Beside, their company policy does not allow them to store any business data in clouds abroad. However, they all have their local AD domain and Windows-only environment. Now, I would like to setup Defender for Business + Huntress MDR as a good and affordable threat protection combo, but here my questions begin. Please, shed some light on this: Does Defender for Business actually need endpoint users to be actually signed-in into their o365 accounts for full protection to work properly? What if they aren't - would full protection still be in place, or would Defender for business functionality drop down to basic antivirus, like regular Defender? Is Defender for Business in my case really so complicated and hard to install and setup? I've read some instructions and there is a ton of documentation, Ps scripts and tools, like Intune and such and despite being 40+ years in computer engineering, I got lost. Mostly because I do not use a ton of Microsoft products daily. Does Defender for Business have some easy to manage Cloud management tool, where I would see and manage all installed Defenders for Business? Or must I learn those Intunes, Azure, o365 Security and Defender portals, which are total overkill for those SMB which I manage? Thank you!
How to get the Protection History from a device
Hello, I would like to get the Protection History without the user intervention. I don't understand why is not in the device page in Microsoft 365 Defender initially... I tried to find a way to doing it in the Advanced hunting, but it's new for me, if some one have the command, thanks in advance. I tried with the Live response, but you can only use the CMD(Is it a way to initiate the Live response with Powershell ?) run a powershell script and tried to get the output file, but i got every time the error : Empty file, even if i doing a -outfile with my PP script and tried to get this specific file... Someone can help me please 🙂 ? Thanks
Security Baselines section disappears
I arrived here from this page... https://learn.microsoft.com/en-us/defender-xdr/entity-page-device ... which details all the possible sections of a given device when located within the Assets->Devices section of the Defender portal. When I click on a machine, I see most of the sections along the top (Overview, Incidents & alerts, Timeline, etc) and I can click on each one but as soon as I click on a device, the 'Security Baseline' section momentarily appears then disappears. The link to Security Baselines is also broken in the link I pasted above. can anyone else access this section? Regards, GrahamSecure Score - Secure Home Folders in macOS
I've performed the recommended manual remediation action (sudo chmod -R og-rw /Users/) on my Macs but Secure Score doesn't recognize it. I have noticed this occurringfor a few item. We have also remediated some things through InTune but still seem to have no movement on the SecureScore. Is this a glitch within or am I missing something altogether.
