Our services GBS TEMPEST & Service GmbH

TEMPEST was originally a military codeword for the study of eavesdropping risks posed by signals unintentionally emitted from information and communication technology. This includes in particular electro-magnetic waves generated by any electronic switching event, which in the worst cases can be picked up with suitable equipment tens or hundreds of meters away.

An IT system is called "tempestified" if the compromising emanations it emits have been reduced to a standards-compliant minimum. All modifications and certification procedures are performed in our inhouse test laboratory.


Certification measurements according to the German zoning model

GBS operates an emanations test laboratory recognized by the BSI, authorized to perform certification measurements according to the national zoning model (Germany).

The BSI zoning model takes into account how buildings and local geography affect the propagation of compromising emanations. Depending on the situation at the location of deployment, it may be possible to use devices with only minor or no special measures for reducing emissions. (Source: www.bsi.de)

Certification measurements

Short-measurement procedures according to the German zoning model

GBS operates an emanations test laboratory recognized by the BSI, authorized to perform short-measurement procedures according to the national zoning model (Germany).

The short-measurement procedure according to the national zoning model is a compressed version of the certification measurement. This measurement procedure is product specific, with specific prescribed measurement instruments and instrument settings.


Certification measurements according to SDIP 27 Level A

GBS operates an emanations test laboratory recognized by the BSI, authorized to perform certification measurements according to SDIP 27 Level A.

Under the internationally used NATO certification levels (SDIP 27 Level A, Level B, Level C), devices are examined for information-carrying emission peaks, which are then analysed and eliminated.

Certification measurements according to SDIP 27 Level A

Short-measurement procedure of devices according to SDIP 27 Level A

GBS operates an emanations test laboratory recognized by the BSI, authorized to perform device-specific short-measurement procedures according to SDIP 27 Level A.

For products tested and nationally certified according to SDIP 27 Level A, we always develop device-specific short-measurement procedures. 

These are specialized verification tests in which areas critical for the respective device type are targeted. They require specialized equipment and procedures and are therefore only applicable to the intended device type.


Development and manufacturing of products complying with SDIP 27

GBS designs and manufactures IT products that comply with SDIP 27 Level A.

The design and development of IT products complying with SDIP 27 Level A is either based on commercial-of-the-shelf (COTS) devices, or is conducted in the form of complete in-house developments based on customer requirements.

This ensures that project-specific solutions according to SDIP 27 Level A are implemented both technically and financially. This includes the entire BSI certification process.

 

Projects are implemented in a sustainable way, according to customer requirements, by providing adapted warranties for the basis products, as well as for the TEMPEST measures, including any required repeat measurements of serviced devices.

The brand name of GBS-designed IT products is “Cerberus”. More information on these is available under “Products”.
