Product overview

Unlock your data treasury without compromising security

The Siemens Data Capture Unit (DCU) delivers a high level of system security and flexibility while providing controlled access to the system from the outside. The DCU is a passive network gateway that allows data transmission – but only in one direction, i.e. from the hardware to the cloud.

The small hardware network component ensures reliable physical (galvanic) separation that prevents interaction between the critical network and the open one. Data transmission is carried out by induction, with the additional advantage of only a minimal impact on the properties of the tapped signal.

 

There is no direct wire connection between the two networks. This will effectively block any attempt to send data via the DCU into the critical network. Another decisive advantage: Neither data communication nor the functionality of the critical network will be impacted or influenced by the DCU in any way, not even if the diode loses power or breaks down completely. At the same time, the integrity of the tapped data is guaranteed at all times.

The principle of freedom from interference

Firewalls must be configured with specific criteria to block incoming packets of information that are deemed to be unsafe. This makes them fallible: they can be configured incorrectly and are vulnerable to attack. When only monitoring or the “store-and-forward” of data is required – a DCU, operating as a one-way gateway, is the secure alternative.
