Enabling and Auditing LSA Protection on Single Computers

Enabling and auditing LSA protection on single computers is a crucial step in securing your system. To enable LSA protection, open the Group Policy Editor and navigate to Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options. Locate the setting labeled “Security Options: Enable Local Security Authority (LSA) Protection” and set it to Enabled.

To audit LSA protection, navigate to Computer Configuration\Windows Settings\Security Settings\Advanced Audit Policy Configuration\System Audit Policies\Security System Extension\Audit Local Account Password and Kerberos Policy and enable auditing for success and failure. This will log any attempts to modify LSA settings on the system.

It’s important to note that LSA.exe is a core file in Windows and should not be deleted or modified. If you’re experiencing errors related to LSA.exe, it could be caused by a virus or malware. In this case, run a virus scan and remove any threats detected.

Configuring LSA Protection Using Group Policy

Disabling LSA Protection and Removing UEFI Variable

Disabling LSA Protection and Removing UEFI Variable are two potential solutions to fixing LSA.exe errors. To disable LSA Protection, open the registry editor by typing “regedit” into the Run dialog box. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa and set the RunAsPPL value to 0. To remove the UEFI variable, restart your computer and enter the UEFI firmware settings. Look for a setting called “Secure Boot” and disable it. Then, remove the UEFI variable by running the command bcdedit /deletevalue {np-sa31…}. It’s important to note that these solutions should only be used if you know what you’re doing, as they can have unintended consequences if done incorrectly. If you’re unsure or uncomfortable making these changes, consider seeking the help of a professional.
