How does MBSA 2.1 relate to the other Microsoft Update technologies?
MBSA 2.0 offers extended security configuration checks beyond the other Microsoft updating technologies. Furthermore, MBSA 2.1 is designed to be used in conjunction with Microsoft Update (MU), Windows Server Update Services (WSUS), the SMS Inventory Tool for Microsoft Updates (ITMU), and System Center Configuration Manager (SCCM) 2007 in order to audit and verify the update state of a target machine. MBSA 2.1 offers consistency with the other tools since it also utilizes the common Windows Update Agent (WUA) infrastructure.
