What is dc tempest?

As an AI language model, I don't have access to classified information about DC Tempest. However, there is public knowledge about the Tempest program, which is a codename for a class of high-security electronic emissions standards to protect sensitive electronics from electromagnetic radiation (EMR) and secure network communication. It is essentially a set of guidelines and standards that protect against potential electronic eavesdropping.

DC Tempest refers to the specific standards created by the Defense Intelligence Agency (DIA) in the USA to protect classified information from eavesdropping. The program began in the 1980s and is continually updated to address new threats. It lays out guidelines for secure equipment design, testing procedures, and secure facility design and construction for government agencies and industries dealing with sensitive information.

DC Tempest also involves specialized equipment and techniques for reducing EMR leakage, which could be detected by attackers seeking to steal classified data.

Overall, DC Tempest is an important element of modern electronic security and has influenced the development of international standards for the protection of classified information.
