The problem
What makes it hard
The interesting property here is not proximity but concentration. Every classified document that enters or leaves passes one and the same copier, one and the same scanner, one and the same desk. An adversary who obtains a single channel out of that function obtains the whole flow, not a sample. The registrar also sits close to the entrance almost every time, often with visitor reception in an adjoining room.
Appropriate level: TEMPEST Level A / RÖS U1 on the copier and the client even where the office is otherwise Level B.
The sealing regime is an organisational matter, not a product property. The copier ships with three sealing levels — user, administrator, engineer — and a tool for removing seals. That presupposes somebody has decided who is who, where the tool is kept, and how a broken seal is recorded. Without that routine the sealing is decoration.

Environments
Environments with the same problem
The technology is the same; the buying process usually is not.
- Embassy or mission in an urban settingThe environment offers no inherent protection: there is no controlled zone to count on.
- Agency office in a shared buildingThe power supply belongs to the property, not to the tenant — and conducted emission does not need to pass through the wall.
- Research laboratoryResults have to leave the zone continuously, which makes the outflow the design problem rather than the workstation.
- File lock and media transferThis is where people work around the protection when it becomes inconvenient — the design has to assume that.
