Scanning Files by Type
As a Forefront Administrator, you will be constantly balancing server performance
with enhanced security controls. Many of the settings like Bias can
directly impact the performance of the server. Finding the proper balance will
ensure that server security is not impacting user productivity. During the
Planning and Design phase, it will be important to understand that every setting
can have an impact on the server. Even a simple change can adversely
impact the performance of the server.
One of the things that Microsoft has done to increase performance and
speed up scans is to only scan fi les that typically contains viruses. Microsoft
realized that using the fi le extension alone to determine the fi le type was not
sufficient. Instead, Forefront looks at the file header, a more secure way
to detect fi le type, even if the extension is spoofed. This allows for a secure
environment without wasting resources on unnecessary fi les.
If you want to scan all attachments, no matter the fi le type, a registry key
change must be made to the ScanAllAttachments key. Changing the value
from 0 to 1 will ensure that Forefront scans all fi les.
