Change service account to avoid cached password in windows registry
Hi , In Microsoft 365 defender > secure score there's a recommendation for me saying "Change service account to avoid cached password in windows registry" , and I can see multiple MSSQL services falling into this recommendations . But the remediation is not very clear , what should I need to do in here ? Thanks ,
Secure Score - gMSA not recognized ("Change service account to avoid cached password in registry")
Hello, we have several SQL Servers who were marked as "exposed devices" in the secure score recommendation "Change service account to avoid cached password in windows registry". The remediation option called for the use of "group Managed Service Accounts" ("gMSA"). We implemented those gMSAs. However, the servers are still marked as exposed. What did we do wrong? Is this a false-positive? I already did some checks with the help of Microsoft Copilot - there are no cached credentials for the gMSAs present, the Accounts are correctly set up (they are working for SQL Server services), and we don't use Microsoft Defender for Identity (if that is needed). Any advises? Thank you very much!
Secure Score - Vulnerability Exceptions Not Registering
I have followed the guide to configure the proper permissions to manage within Defender. Device groups have been created based off tags we applied to the devices, and the device groups register the expected number of devices. We apply an exception to the vulnerability recommendation based off the device group, looking at the individual device pages we can confirm the recommendation is excluded and it all appears to work as intended up to this point. The problem starts on the vulnerability dashboard. The recommendation shows it is in partial exception status however none of the statistics or data reflect this including our secure score. I can confirm making a global exception works as expected and we can see the score adjust properly. Has anyone experienced this before or have any pointers? We have been working at this for weeks trying different things without luck, we are ensuring to leave adequate sync times.
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 Mathiew
Can't find correct RBAC permissions to approve AIR actions
I've been configuring custom RBAC roles, and even though the "Response (manage)" permission in the Security Operations permissions group includes "approve or dismiss pending remediation actions," it doesn't work. I've tried it with pending "soft delete emails" actions in the Action Center, and I get an error. The only way we can approve or reject these actions is with the Entra Security Administrator role checked out. Does anyone know which RBAC permission is supposed to grant the rights to approve these remediation actions?
OpenSSL
We have the recommendation to update OpenSSL. However, we can not figure out how to actually do this. There seems to be no installed location of OpenSSL so how can we update this? I have found a few posts/comments that have led me to this page New OpenSSL v3 vulnerability: prepare with Microsoft Defender for Cloud - Microsoft Community Hub but this doesn't actually help you at all. Going to OpenSSL's site for download just gives you a repository of files that don't actually update anything. So what are we supposed to do to get this remediated?
Update OpenSSL recommendation
Hi all, I've been trying to find out how to deal with "openssl" recommendation that I get on almost all end user computers in Defender. I'm just not sure how to deal with it... It doesn't seem to be a particular app or so.... From what I see when I check the "software inventory" page of the devices, there are many references to different files/dll?? See some few examples below: c:\program files\windowsapps\e046963f.aimeetingmanager_3.1.18.0_x64__k1h2ywk1493x8\aimeetingmanager\libcrypto-3-x64.dll c:\program files\zoom\bin\libcrypto-3-zm.dll c:\program files\dell\dell peripheral manager\libcrypto-1_1-x64.dll c:\windows\system32\driverstore\filerepository\udcdriver.inf_amd64_d70e6df8e9ed1889\x64\service\libssl-1_1-x64.dll How you deal with it? .. is that something that can be pushed via Intune..?
Delete computer application - Defender 365
Hey, I'm trying to fix weaknesses that are marked on our Microsoft 365 Defender. I'm created an Intune package to install the new version of Firefox - however it didn't remove the old versions. Is there a way for me using: Defender/Intune/GPO to remove multiple old versions of Firefox for example, that are installed on the users computers? I can see the list of devices that are affected but how can I fix it as quickly as possible? Thanks!THE VIRTUAL NINJA SHOW SEASON 4 RECAP
Did you miss any of the Ninja Show this season? Not to worry! We have assembled a synopsis of each episode highlighting the central focus points established in our discussions. (However, reading the main points are never as good as the real thing... Watch any episode on demand here!) Overview: Episodes 1-5 of this season were part of our first mini-series! Focused on incident response cases, experts from several teams across the Microsoft 365 Defender suite shared their knowledge regarding incident investigations as well as the critical tools and capabilities available to help improve defense in any organization.
