OfficeScan 10.6 Administrator's Guide - Trend Micro™ Online Help

Managing Data Protection and Using Digital Asset Control
This means that if an email is sent to an SMTP server on the monitored targets list, the
email is monitored. If the SMTP server is not on the monitored targets list, OfficeScan
checks the other lists. If the SMTP server is not found on all the lists, the email is not
monitored.
For emails sent through other protocols, OfficeScan only checks the following lists:
1. Monitored email domains
2. Non-monitored email domains
FTP
When OfficeScan detects that an FTP client is attempting to upload files to an FTP
server, it checks for the presence of digital assets in the files. No file has been uploaded
at this point. Depending on the Digital Asset Control policy, OfficeScan will allow or
block the upload.
When you configure a policy that blocks file uploads, remember the following:
• When OfficeScan blocks an upload, some FTP clients will try to re-upload the files.
In this case, OfficeScan terminates the FTP client to prevent the re-upload. Users
do not receive a notification after the FTP client terminates. Inform them of this
situation when you roll out your Digital Asset Control policies.
• If a file to be uploaded will overwrite a file on the FTP server, the file on the FTP
server may be deleted.

HTTP and HTTPS
OfficeScan monitors data to be transmitted through HTTP and HTTPS. For HTTPS,
OfficeScan checks the data before it is encrypted and transmitted.
