Lsass - Lsass.exe - LSA shell

Lsass - Lsass.exe

Lsass.exe (LSASS stands for Local Security Authority Subsystem Service) is a Windows 2000/XP native system process which manages local security and user authentication procedures via the WinLogon service. It is a local authentication server which creates an access token whenever a user is successfully authenticated, in order to allow that user to log in.

The original Lsass service had a security hole, exploited by the Sasser virus, which must be fixed!
