The study and control of spurious electrical signals that are emitted by electrical equipment is called:
A.
IDS
B.
Zones
C.
White noise
D.
TEMPEST
Explanation:
TEMPEST was developed in the 1950s by the U.S. government to address
electromagnetic radiation being emitted from electrical equipment. Data can be
captured via electrical signals and reconstructed, which threatens the
confidentiality of sensitive data.
