If you’re seeing the “Local Security Authority Protection is OFF. Your Device Maybe Vulnerable” message in the Device Security section of the Windows Security app in Windows 11. You’re not alone.
The Local Security Authority (LSA) is a critical component in Windows operating systems, including Windows 11. It is responsible for enforcing security policies and performing various security-related tasks to protect the operating system.
The LSA process plays a vital role in ensuring the integrity and security of the system by preventing unauthorized access and tampering by malware or malicious actors.
Due to this reason, Microsoft doesn’t was users to disable this security feature. Out of the box it’s enabled. In case users disable it, then they will see a message Local Security Authority Protection is OFF. Your device may be vulnerable.
So what’s wrong with it? As per the reports, users saying that they have enabled this feature and even after rebooting the PC error message still appears. Also, the security app keeps sending the notification to enable this feature which is annoying.
Basically, it’s a visual or GUI bug in the Windows security app which was first experienced by users in March 2023, and some users are still seeing this message as of June 2023. Microsoft already tried to fix this bug by pushing a Windows Defender update, but they failed.
