A yellow triangle appeared on the Windows Security iron yesterday. It says that Local Security Authority protection is off. Your device may be vulnerable.
I can press Go to settings or Dismiss but when I click go to settings, a notification saying "the page You want to access doesn't contain required functions and is unavailable".
There is also no option to turn the protection on in the Device Security panel (there is only "dismiss" option).
When I was looking at it yesterday, there was also a notification that "The tpm module is unavailable" but today it doesn't show. I checked the device manager and uefi and both say that the tpm is enabled.
I've found an advice to turn on SMV in UEFI (in the CPU settings) to solve the problem but I don't want to change anything in BIOS without consultation as I'm no expert. I've also found a reply from a truste source that this whole problem is a Microsoft bug and it's better to just wait till they fix it.
What should I do?
Screenshots are in Polish, I hope they can be useful somehow. The first one shows the notification about a page being not available and the second shows the Device security panel (the notification from the first screenshot displays when I close the device security page or when I click on "go to settings" below the information that the protection is turned off). There is also an information (second screenshot) that "standard device security is not supported".
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Microsoft have just posted that they have resolved the "Local Security Authority protection is off" issue in an update. Has anyone tried to apply it from Windows Update?
Resolution: This issue was resolved in an update for Windows Security platform antimalware platform KB5007651 (Version 1.0.2306.10002). If you would like to install the update before it is installed automatically, you will need to check for updates.
Hi
Did someone find a solution for this issue? because i'm facing the same thing and the fact this is a thing and Microsoft is not addressing it as top priority instead leaving users doing random confusing test in their official support forum, without any official representative from the company tech support is sooo frustrating, What is going on we are facing a huge security vulnerability here and Microsoft doesn't even bother to comment or release a fix for this long!!!!
Hi,
Thank you for your suggestions. As per your troubleshooting steps, I don't see RunasPPL option in LSA. Kindly Suggest
This thread was started back in March. It is now June 27th and I just discovered I have the same issue.
I turned on my laptop for the first time since April and noticed the yellow triangle over the security center in the system tray.
When I click it, the security center opens and I see the same message "Local Security Authority protection is off. Your device may be vulnerable."
If I click on view details, the Core Isolation section has the yellow triangle and the same error about the LSA protection being off.
I can then click the Core Isolation Details link and on the next page, Memory Integrity and Microsoft Vulnerable Driver Blocklist are both ON.
I have tried turning them off, rebooting, and turning them back on and rebooting again but this problem persists. It's been at least over 4 months. Is there going to be a fix for this?
Again, I also went into settings and windows update and checked for updates but it says my system is fully up to date.
Good morning,
Here is an official link from Microsoft dealing with this subject:
https://learn.microsoft.com/en-us/windows/release-health/status-windows-11-22h2#3048msgdesc .
In this link they say this:
Workaround: If you have enabled Local Security Authority (LSA) protection and have restarted your device at least once, you can dismiss warning notifications and ignore any additional notifications prompting for a restart. You can verify that LSA protection is enabled by looking in Event Viewer using the information available here. Important: Currently, we do not recommend any other workaround for this issue.
That's what I did and won't do anything else since recommended by Microsoft, good luck
