Espionage And Terrorism
(From the NSA Handbook)
During your security indoctrination and throughout your NSA career you will
become increasingly aware of the espionage and terrorist threat to the United States. Your vigilance is the best single defense in protecting NSA
information, operations, facilities and people. Any information that comes to
your attention that suggests to you the existence of, or potential for,
espionage or terrorism against the U.S. or its allies must be promptly reported
by you to the Office of Security.
There should be no doubt in your mind about the reality of the threats. You
are now affiliated with the most sensitive agency in government and are
expected to exercise vigilance and common sense to protect NSA against these
threats.
