Research laboratory
Results have to leave the zone continuously, which makes the outflow the design problem rather than the workstation.

The problem
What makes it hard
The adversary has time and patience and is often interested in one narrow technical area rather than in everything. Visiting researchers and doctoral students rotate through. The publishing culture pulls towards openness. And the laboratory contains measurement equipment that radiates strongly itself and that nobody is going to replace with an approved equivalent, because no such equivalent exists.
Appropriate level: TEMPEST Level B / RÖS U2 normally, TEMPEST Level A / RÖS U1 for positions against the façade.
The laboratory equipment breaks the chain. An oscilloscope bench in the same room as a Level A client removes the protection in practice. Either the room is divided into two zones, or a lower level is accepted deliberately.
How it is built
Flow out of the zone: a diode in and out
Two diodes in opposite directions are not a bidirectional link, as long as they stay physically separate.
See the full pattern- Approval document per article numberThe two diodes are requested separately — a supplier statement says nothing about the unit.
- The direction sits in the opticsNo rule, no configuration, no setting that can be changed afterwards.
- One-way path
- Data path
- Path that does not exist

Reading and references
Explained in
Named customer references are not published. What we can show is the solution area this environment belongs to, and the reasoning behind the design.
Environments
Environments with the same problem
The technology is the same; the buying process usually is not.
- Command and control centreSeveral networks meet at one desk, and the operator must never have to think about which one is in front of them.
- The bank trading deskMany screens, many networks and no tolerance for a switching delay measured in seconds.
- Backup of a protected networkBackup is the only flow where the volume is large, completeness is absolute and the time window is set by someone else.
- Replacing an air gapMapping the flows comes before choosing the product — the air gap is upheld by manual work that is rarely counted as cost.
