Microsoft is again pushing a Defender Antivirus update that fixes a known issue triggering Windows Security warnings that Local Security Authority Protection is off.
Microsoft acknowledged this issue impacts Windows 11 21H2 and 22H2 systems after numerous user reports about "Local Security Authority protection is off. Your device may be vulnerable." warnings, although LSA Protection was already enabled.
To check if LSA protection is enabled on your computer, you can use the Windows Event Viewer and look for an "LSASS.exe was started as a protected process with level:4." Wininit event which confirms that the process is isolated and secured by LSA Protection.
Two months ago, in March, Microsoft announced that LSA Protection would be enabled by default for Windows 11 Insiders in the Canary channel, provided their systems passed an incompatibility audit check.
