Client OS

Question
When and how do you use Unhandled Applications within SafeGuard LAN Crypt?

Answer
All applications registered as unhandled are ignored by the SafeGuard LAN Crypt filter driver and file access by these applications will therefore be ignored by SafeGuard LAN Crypt.

This is mainly used for two reasons:

  • Applications that should not be able to read sensitive data unencrypted. For example: a backup program that is installed on the client would in this case backup the files in encrypted form or programs like a web browser that could be used by an attacker to steal sensitive information.
  • Applications that cause problems if used at the same time as SafeGuard LAN Crypt but don’t need to work with any encrypted data.

The application should be registered in the LAN Crypt Configuration as an Unhandled Application.

The Unhandled Application could also be added directly via a Registry entry:

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Control\Utimaco\SGLCENC
Value Name: TrustedPrograms
Value Type: REG_SZ
Value: ntbackup.exe
Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Control\Utimaco\SGLCENC
Value Name: TrustedProgramMethod
Value Type: REG_dword
Value: Defines how child processes of the unhandled applications are handled.

0 Default value
1 All registered applications are ignored by the filter driver.
2 All registered applications and their child processes are ignored by the filter driver.

Example: "TrustedProgramMethod"=dword:00000002
