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.

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 for more information on components.

Smart Scan Server Types

The Smart Scan Server to which a client connects depends on the client’s location. Internal smart scan clients connect to a local Smart Scan Server, while external smart scan clients connect to the Trend Micro Global Smart Scan Server. The following table provides a comparison between the two Smart Scan Server types:
