When the goal is to shield IT equipment, a more cost-effective approach is to block electromagnetic emanations at the server rack level using copper, aluminum, and other materials. government agencies and contractors often use shielded rooms called SCIFs (Sensitive Compartmented Information Facilities) to protect equipment from eavesdropping.īuilding out a SCIF is expensive, and the facility will require ongoing maintenance. In many cases, there is not a TEMPEST option for innovative applications.Īnother approach is to shield the room that houses RED equipment. However, TEMPEST devices are expensive and tend to lag behind current technology. government agencies and approved contractors to devices for general commercial use. There are three categories of TEMPEST-shielded devices, ranging from highly secure equipment available only to U.S. TEMPEST calls for the use of specially shielded devices for processing NSI. Therefore, the two must be shielded or separated by adequate distance. For example, signals from RED cables can be unintentionally transmitted by nearby BLACK cables. The distinction also helps ensure that BLACK equipment does not become a source of CE threats. The TEMPEST specifications can then be applied to the RED equipment to shield it from electromagnetic and RF radiation threats.
The first step is to separate systems, components, cables, and circuits that handle NSI in plain text from those that do not. BLACK designation forms the basis of a TEMPEST security strategy. Sounds produced by keyboards, relays, and other mechanical devices that can be intercepted and interpreted. Intended signals that are angle modulated or amplified. Signals that are unintentionally conducted or noise-induced over power lines, signal lines, etc. For example, computer monitors emit electromagnetic radiation that can be intercepted and displayed on another monitor. RED baseband signals are attenuated, meaning they lose strength or become distorted due to distance, shielding, or other factors. BLACK systems process non-NSI data or data that has been encrypted. RED systems include all electronic equipment that processes NSI. The NSA uses the term “RED baseband signals” to describe CE that could expose national security information (NSI). It also specifies distances between equipment and walls and building pipes and the space between cables carrying classified vs. It includes strict requirements for the electromagnetic shielding of equipment, rooms, or even entire buildings. Today, it describes various techniques for preventing compromising emanations (CE). government project in the late 1960s that studied this threat. Computers and other electronic devices emit radio frequency (RF) signals and electromagnetic radiation that cybercriminals can use to reconstruct intelligible data. National Security Agency (NSA) specification for protecting against data theft through the interception of electromagnetic radiation.
