When figuring out what TEMPEST mitigations your facility needs, you’ll be relying on guidance from a government Certified TEMPEST Technical Authority (CTTA). TEMPEST is a major concern when constructing secure facilities, and there are a variety of ways to keep those unintended emanations from escaping and being picked up by adversaries. Generally, the more power this equipment uses, the larger the TEMPEST footprint will be. The TEMPEST footprint emanates in every direction from the equipment like a sphere. This means anyone with the knowledge could potentially pick up compromising emanations that escape your facility.Įvery piece of electronic equipment that processes information has what’s known as a TEMPEST profile or footprint, which is the point from your processing equipment to the farthest point where emanations could be picked up or exploited. Specialized equipment that can capture these radio frequencies and exploit the unintended transmission of data is available commercially. When those data hold national security-related information, the disclosure of it can be potentially dangerous. Whatever data these pieces of equipment process electronically can potentially be picked up and analyzed. TEMPEST is the study, investigation and mitigation of these compromising emanations.Įmanations can come from any electronic equipment, whether it’s a personal laptop or a commercial server. These emanations are unintended data-related or intelligence-bearing radio frequency signals which, if intercepted, can disclose information related to national security. On top of the more obvious physical and acoustic considerations, you also need to deal with mitigations related to unintentional emanations that could escape your SCIF. ![]() ![]() When constructing a SCIF or SAPF, there are numerous security concerns you need to address. Understand how compromising emanations can impact the security of your SCIF or SAPF
