The Local Security Authority protection is off - Windows 11 Home

Anonymous

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".

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 Bob,

    Thank you for your help. Can you define antivirus program? Did the representative mean the antivirus services that Microsoft already provides in Windows 11? Or third party antivirus software like Mcafee or Norton antivirus.

    Thanks for your help

    Currently, LSA has been fixed but MSFT failed to include a proper certificate of signature. This is what the Entry should look like for LSA when it is working with the latest package.

    P.s. I apologize, this is found under Administrative EventsImage

    Start Menu>Search for EventViewer>Open

    Select Windows Logs>Application

    On right hand side, select "Filter current log"

    Type "LSA" in "Event Sources" field> Press Enter Key

    Any Failures by the LSA should be listed.
