Removable Storage

Trend Micro Apex One monitors data transmissions to or within removable storage devices. Activities related to data transmission include:

When a file to be transmitted contains a data identifier, Trend Micro Apex One either blocks or allows the transmission.

For a list of supported removable storage devices and applications that facilitate data transmission activities, see the Data Protection Lists document at:

The handling of file transmission to a removable storage device is a straightforward process. For example, a user who creates a file from Microsoft Word may want to save the file to an SD card (it does not matter which file type the user saves the file as). If the file contains a data identifier that should not be transmitted, Trend Micro Apex One prevents the file from being saved.

For file transmission within the device, Trend Micro Apex One first backs up the file (if its size is 75MB or less) to %WINDIR%\system32\dgagent\temp before processing it. Trend Micro Apex One removes the backup file if it allowed the file transmission. If Trend Micro Apex One blocked the transmission, it is possible that the file may have been deleted in the process. In this case, Trend Micro Apex One will copy the backup file to the folder containing the original file.

Trend Micro Apex One allows you to define exceptions. Trend Micro Apex One always allows data transmissions to or within these devices. Identify devices by their vendors and optionally provide the device models and serial IDs.
