The following terms used in this document are not found in NSTISSI No. 4009, National Information Systems Security Glossary.

1. (U) Technical Security: The discovery, elimination, and mitigation of security vulnerabilities that can be exploited by technical means. It includes all facets of security that involve the detection and/or neutralization of technical collection threats or the application of security technology; the traditional fields of TEMPEST and technical surveillance countermeasures (TSCM); and extends to new techniques, technology, and instrumentation that may allow exploitation of security vulnerabilities by technical means.

2. (U) Technical Security Evaluation (TSE). An evaluation of all factors related to potential vulnerabilities of technical penetration of a facility, system, network, product, or equipment. Typical considerations include security against acoustical, optical, audio frequency, radio frequency, and other methods of penetration as well as adequacy of electronic protection. A TSE includes TSCM, TEMPEST, and TEAPOT considerations.
