IM Applications<br />

<strong>OfficeScan</strong> monitors messages and files that users send through instant messaging (IM)<br />

applications. Messages and files that users receive are not monitored.<br />

For a list of supported IM applications, see:<br />

http://docs.trendmicro.com/en-us/enterprise/officescan.aspx<br />

When <strong>OfficeScan</strong> blocks a message or file sent through AOL Instant Messenger, MSN,<br />

Windows Messenger, or Windows Live Messenger, it also terminates the application. If<br />

<strong>OfficeScan</strong> does not do this, the application will become unresponsive and users will be<br />

forced to terminate the application anyway. Users do not receive a notification after the<br />

application terminates. Inform them of this situation when you roll out your Digital<br />

Asset Control policies.<br />

SMB Protocol<br />

<strong>OfficeScan</strong> monitors data transmissions through the Server Message Block (SMB)<br />

protocol, which facilitates shared file access. When another user attempts to open, save,<br />

move, or delete a user’s shared file, <strong>OfficeScan</strong> checks if the file is or contains a digital<br />

asset and then allows or blocks the operation.<br />

Note: The Device Control action has a higher priority than the Digital Asset Control action.<br />

For example, if Device Control does not allow files on mapped network drives to be<br />

moved, transmission of digital assets will not proceed even if Digital Asset Control<br />

allows it. For details on Device Control actions, see Permissions for Storage Devices on<br />

page 8-4.<br />

For a list of applications that <strong>OfficeScan</strong> monitors for shared file access, see:<br />

Webmail<br />

Web-based email services transmit data through HTTP. If <strong>OfficeScan</strong> detects outgoing<br />

data from supported services, it checks the data for the presence of digital assets.<br />
