TEMPEST Attacks and Cybersecurity

Abstract

Broad usage of Information and Communication Technologies (ICT) and the Internet have made cybersecurity a vital issue. One of the less known threat for cybersecurity is TEMPEST (Transient Electromagnetic Pulse Emanation Standard) which has become more apparent today. TEMPEST is an information security term that refers to the examination and control of unwanted electromagnetic energy emissions caused by electrical and electronic devices. As a result of TEMPEST attacks, confidential information such as state secrets, personal information such as bank passwords, and more information can be passed on to the attackers. Unlike other known cyber-attack methods, TEMPEST attack methods are kept secret and those who are exposed to TEMPEST attacks are not aware of these attacks. The concept of TEMPEST is a less known cybersecurity component which can cause much greater damage if the necessary cybersecurity measures are not taken. The purpose of this study is to present a review of TEMPEST attacks and countermeasures. The study also highlights the importance of using national cybersecurity products that passed the national TEMPEST cybersecurity testing certification.
