TEMPEST (Telecommunications Electronics Material Protected from Tempest Standards)

TEMPEST is a set of standards and practices designed to prevent unauthorized access to sensitive information through electromagnetic signals emitted by electronic devices. Essentially, electronic equipment can unintentionally radiate signals that someone with specialized equipment might intercept, potentially revealing confidential data. TEMPEST measures, enclosures, and procedures are used to minimize these emissions, protecting government, military, and corporate communications from eavesdropping. It ensures that devices are shielded and operated in a way that makes it extremely difficult or impossible to extract sensitive information through signal interception, thus maintaining information confidentiality and security.
