Local Security Authority Subsystem Service
From Free net encyclopedia
Local Security Authority Subsystem Service (LSASS), is a process in Microsoft Windows operating systems that verifies the user logging on to a Windows computer or server.
The Sasser worm exploited a vulnerability in LSASS to spread via a remote buffer overflow in computers running Microsoft Windows XP and Windows 2000. The worm is particularly potent in that it can spread without any interaction with humans, nor does it 'travel by email' like many other worms.
