Smart Scan Server

The smart scan solution makes use of lightweight patterns that work together to provide
the same protection provided by conventional anti-malware and anti-spyware patterns.
These patterns originate from the Trend Micro ActiveUpdate server and are made
available to Smart Scan Servers and the OfficeScan server.
A Smart Scan Server hosts the Smart Scan Pattern. This pattern is updated hourly and
contains majority of the pattern definitions. Smart scan clients do not download this
pattern. Clients verify potential threats against the pattern by sending scan queries to the
Smart Scan Server. In the smart scan solution, clients send identification information
determined by Trend Micro technology to Smart Scan Servers. Clients never send the
entire file and the risk of the file is determined using the identification information.
Note: The other pattern used in the smart scan solution, called Smart Scan Agent Pattern, is
hosted on the client update source (the OfficeScan server or a customized update
source) and downloaded by clients.
There are no component download overlaps between the Smart Scan Server and the
OfficeScan server because each server downloads a specific set of components. A Smart
Scan Server only downloads the Smart Scan Pattern while the OfficeScan server
downloads all the other components. See OfficeScan Components and Programs on page 4-2
for more information on components.
