What is lsm.exe?

Local Security Authority Subsystem Service (LSASS), is a process in Microsoft Windows operating systems that is responsible for enforcing the security policy on the system. It verifies users logging on to a Windows computer or server, handles password changes, and creates access tokens.

Overview

lsm.exe executes as a process under the SYSTEM account with extensive privileges (the system and the administrator accounts have the same file privileges) typically within the context of its parent wininit.exe (Windows Start-Up Application by Microsoft). This version is designed to run on Windows 7 and is compiled as a 64 bit program.
