Lsass.exe
Local Security Authority Process
Description
Lsass.exe is the Local Security Authority Subsystem Service (LSASS) shell. It's a process that enforces the security policy on the PC. LSASS verifies users logging in, handles password changes, and creates access tokens. It also updates the Windows Security Log. This is considered a critical process within Windows and cannot be terminated with Task Manager.
Lsass.exe is a 32/64-bit executable for a graphics UI style application.
The WinSxS directory holds Windows Side-by-Side DLLs. WinSxS allows multiple versions of the same DLL (code libraries) to exist on the same system. This ensures that every application will get the DLL version they were tested and designed for. The result is improved application and system stability. See details for full directory location.
There are no known security risks in using Lsass.exe assuming it has not been modified or replaced by virus or malware and it resides in the default directory. This file is installed as part of the Windows operating system.
The following
files are required when running this program. These may call other files, and there can be additional required files not in this list. Required files for non-Core OS programs above are not included.
