MBSA downloads the wsusscn2.cab file at the initial scan, or any time the file has changed on the Microsoft Web site. Internet activity caused by MBSA can be completely eliminated by using the /nvc (no tool version check), /catalog (offline catalog file), and /nd (do not download) parameters of the command-line tool described in MBSA Help. Note: To ensure that MBSA has access to the most current versions of these files, you should download them on a weekly basis or after security bulletins are released by Microsoft. This is especially important in the case of the security update catalog (wsusscn2.cab) because Microsoft releases an updated version of this file whenever new security bulletins are released or updated.
