"Security Operations Admin User" Predefined Critical Asset classification
In our XDR instance, the new "Security Operations Admin User" predefined Critical Asset classification (introduced last month) contains a few non-privileged users. I can't figure out by what logic they were added to this classification. It seems that the users may be using laptops that are classified as "Security Operations Admin Devices," but I can't figure out why those devices are grouped that way, either. If it were a matter of an IT user logging onto one of the machines for support, there would inevitably a lot MORE users and devices in these groups. Does anyone know what kind of activity Microsoft uses to classify users and devices as "security operations admins?"
Audit logs for Vulnerability Management Remediations
Hello all, Are there any audit logs that can be queried for the creation of Remediations under Endpoint Vulnerability Management (https://security.microsoft.com/remediation/remediation-activities)? I know that there are API endpoints that can be queried for this information, but we are looking for additional options. The endgame is to have a ticket created in our external help desk ticketing system when someone creates a Remediation from a Recommendation. Any advice is appreciated! Thanks, - Steve
Full 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? Best regards MathiewAutomated Attack Disruption Testing
In the past I vaguely remember seeing attack simulation walkthroughs for MDE and there still is a link in the MDE onboarding to explore simulations and tutorials but that now just takes me to the XDR homepage. There are cases where we're talking to customers about the capability of Defender XDR and want to showcase in a safe way, without endangering demo devices. With Automated Attack Disruption announcements at Ignite 2024, I'd like to be able to showcase this particularly in the area of Ransomware protection, similar to the case study "protecting against ransomware when others couldn't" from the Ignite AI-driven Ransomware Protection session. Does anyone have an updated link to the attack simulation walkthroughs that were available and also any similar walkthoughs for Automated Attack Disruption?
Issues blocking DeepSeek
Hi all, I am investigating DeepSeek usage in our Microsoft security environment and have found inconsistent behaviour between Defender for Cloud Apps, Defender for Endpoint, and IOC controls. I am hoping to understand if others have seen the same. Environment Full Microsoft security and management suite What we are seeing Defender for Cloud Apps DeepSeek is classified as an Unsanctioned app Cloud Discovery shows ongoing traffic and active usage Multiple successful sessions and data activity visible Defender for Endpoint Indicators DeepSeek domains and URIs have been added as Indicators with Block action Indicators show as successfully applied Advanced Hunting and Device Timeline Multiple executable processes are initiating connections to DeepSeek domains Examples include Edge, Chrome, and other executables making outbound HTTPS connections Connection status is a mix of Successful and Unsuccessful No block events recorded Settings Network Protection enabled in block mode Web Content Filtering enabled SmartScreen enabled File Hash Computation enabled Network Protection Reputation mode set to 1 Has anyone else had similar issues when trying to block DeepSeek or other apps via Microsoft security suite? I am currently working with Microsoft support on this but wanted to ask here as well.Why there is no Signature status for the new process in the DeviceProcessEvent table?
According to the schema, there is only field for checking the initiating (parent) process digital signature, named InitiatingProcessSignatureStatus. So we have information if the process that initiated the execution is signed. However, in many security use-cases it is important to know if the spawned (child) process is digitally signed. Let's assume that Winword.exe (signed) executed unsigned binary - this is definitely different situation than Winword.exe executing some signed binary (although both may be suspicious, or legitimate). I feel that some valuable information is not provided, and I'd like to know the reason. Is it related to the logging performance? Or some memory structures, that are present only for the already existing process?
