What does the acronym TEMPEST refer to in tactical communications?

The acronym TEMPEST refers to a set of standards designed to prevent the interception of unintentional emissions. This is critical in tactical communications, where maintaining the confidentiality and integrity of transmitted information is vital for operational security. TEMPEST standards address concerns related to emanations from electronic devices that may unintentionally leak sensitive information, allowing unauthorized parties to potentially capture and exploit this data.

The implementation of TEMPEST measures involves various techniques, such as shielding, filtering, and secure physical layouts, ensuring that any radiation produced by equipment does not reveal classified or sensitive information. This focus on protecting against electromagnetic emissions is essential for the military to safeguard its communications from eavesdropping and spying, thereby ensuring secure and reliable tactical operations.
