TEMPEST Doors

TEMPEST stands for "Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions". It is a specification created by the US National Security Agency (NSA) to safeguard against data theft caused by the interception of electromagnetic radiation. Electronic devices, such as computers, emit radio frequency (RF) signals and electromagnetic radiation that cybercriminals can use to extract readable data.

One way to prevent TEMPEST attacks is by installing secure doors in areas where sensitive electronics are located. These doors are designed to block the transmission of electromagnetic radiation, preventing cybercriminals from intercepting any sensitive data. These doors are typically made of metal and are lined with special materials that absorb and reflect RF signals, making it difficult for anyone to intercept them.

To be effective, these doors must be installed correctly and in a way that minimizes any gaps or openings. Even the smallest gap can allow RF signals to leak out, potentially compromising the security of the area. Additionally, anyone who enters or exits the secured area must do so through the secure door, ensuring that no unauthorized individuals can gain access to the sensitive electronics.

Overall, secure doors are an effective way to prevent TEMPEST attacks, and they are widely used in government agencies, military installations, and other organizations that deal with sensitive information.
