The classified [National Security Agency](/wiki/National_Security_Agency "National Security Agency") program [TEMPEST](/wiki/Tempest_%28codename%29 "Tempest (codename)") focuses on both the spying on systems by observing electromagnetic radiation and the securing of equipment to protect against such attacks.

The [Federal Communications Commission](/wiki/Federal_Communications_Commission "Federal Communications Commission") outlines the rules regulating the unintended emissions of electronic devices in [Part 15](/wiki/Title_47_CFR_Part_15 "Title 47 CFR Part 15") of the Code of Federal Regulations Title 47\. The FCC does not provide a certification that devices do not produce excess emissions, but instead relies on a self\-verification procedure.
