Editing Tempest (codename) (section)

==Certification==
The information-security agencies of several NATO countries publish lists of accredited testing labs and of equipment that has passed these tests:

*In the U.S.: NSA TEMPEST Certification Program<ref>{{cite web |url=https://www.iad.gov/iad/programs/iad-initiatives/tempest.cfm|title=TEMPEST Certification Program - NSA/CSS|publisher=iad.gov|access-date=2017-07-27}}</ref>

The [[United States Army]] also has a TEMPEST testing facility, as part of the U.S. Army Electronic Proving Ground, at [[Fort Huachuca]], [[Arizona]]. Similar lists and facilities exist in other NATO countries.

TEMPEST certification must apply to entire systems, not just to individual [[electronic component|components]], since connecting a single [[shielded cable|unshielded]] component (such as a cable or device) to an otherwise secure system could dramatically alter the system RF characteristics.
