<\/a><\/figure>\n<\/div>\n\n\nWhat Is Local Security Authority Protection in Windows 11?\n<\/h2>\n\n\n\n
The Local Security Authority (LSA) is the system component that enforces security policies in Windows 11. It authenticates users during the login process, creates access tokens, and manages password policies. The underlying process is LSASS.exe<\/a>.\n<\/p>\n\n\n\n To bolster security, Windows 11 offers a feature called Local Security Authority protection. It runs the LSASS process in protected mode, blocking unsigned drivers and plugins from loading and preventing potential attacks from malicious code.\n<\/p>\n\n\n\n The “Local Security Authority protection is off” notification pops up after installing Microsoft Defender Antivirus Version 1.0.2302.21002, regardless of having the feature on or off on your computer. Microsoft has acknowledged it as a known Windows 11 version 22H2 issue<\/a>.\n<\/p>\n\n\n\n You’ve got three methods to deal with a persistent “Local Security Authority protection is off” security warning in Windows 11. You can:\n<\/p>\n\n\n\n Unless you’re on a new Windows 11 installation, the “Local Security Authority protection is off” error likely appears when Local Security Authority protection is enabled on your system. \n<\/p>\n\n\n\n Microsoft’s suggestion\u2014if Microsoft Defender Antivirus Version 1.0.2306.10002 or later is not available to you\u2014is to check if Local Security Authority protection is active via the Event Viewer and dismiss the warning if you’ve already restarted your PC at least once after receiving it.\n<\/p>\n\n\n\n Begin by confirming that the Local Security Authority is running in Protected Mode via the Event Viewer<\/a>. To do that:\n<\/p>\n\n\n\n To dismiss the “Local Security Authority protection is off” notification in Windows 11:\n<\/p>\n\n\n\n According to Microsoft, newer versions of Microsoft Defender Antivirus\u2014Version 1.0.2306.10002 and later\u2014fix the “Local Security Authority protection is off” error in Windows 11. Hence, installing all pending updates through Windows Update is the best way to deal with the issue.\n<\/p>\n\n\n\n To do that:\n<\/p>\n\n\n\n If the Local Security Authority protection isn’t active when checking with the Event Viewer, updating Windows 11 fails to resolve the issue, or you don’t have newer updates to Microsoft Defender Antivirus available, you must modify the system registry to resolve the issue.\n<\/p>\n\n\n\n Warning<\/span>: Microsoft does not recommend workarounds to dismiss the “Local Security Authority protection is off” security notification, so only go through the steps below if the methods above fail. You should also back up the system registry<\/a> before you go ahead.\n<\/p>\n\n\n\n Computer\\HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa \n<\/span><\/p>\n\n\n Note<\/span>: If one or both keys aren’t present, you must create them manually\u2014right-click Lsa<\/span> on the sidebar and select DWORD (32-bit) Value<\/span>, name it after the missing key, and save with a value of 2<\/span>.\n<\/p>\n\n\n\n Alternatively, you can modify the system registry via Windows PowerShell.
