A thoughtful review shows the evolution of the program over a period of
some 40+ years though these documents, and if you are well versed in
TSCM related matters you can develop a pretty good understanding of how
to provision your training and equipment, and procedures to overcome
many of the historical problems presented in this document collection.
The bottom line, take away message, is that it is vital to obtain a very
strong hands on technical background before you attempt to study TSCM,
and to develop a high level of expertise with spectrum analyzers and RF
analysis equipment and procedures above all else, and to become a
wizards with oscilloscopes, amplifiers, EMC, EMI measurements, and of
measuring super low powered RF signals that are buried deep inside the
noise floor. Then, and only then, begin to study telephone technology at
the raw component levels, and study not so much the software side
initially, but actually focus on when the components actually do and how
they are arranged first. Certainly you will need to study the software
side, but not until you fully grasp heavy duty physical layer telephone
analysis.
Well experienced TSCM specialists will be utterly appalled at how little
time is actually spent on physical inspections , and how they rely to
painfully on very limited test equipment. This is deeply unfortunate as
it is very easy to make eavesdropping equipment that wreaks havoc on
TSCM efforts that rely on the equipment to do most of the work, instead
of the users.
The art and craft of TSCM business is actually the physical search, and
the test equipment merely suggests where a physical inspection should
take place.
In 2012 I will be posting to my website a lot of tutorials on how to
trace phone wires, analysis of phones, how to map out telephones poles,
what the markings on them mean, data about using spectrum analyzers and
other equipment to find very covert signals, and a wealth of other
information that should help to improve the overall understanding of
TSCM matters.
I will also be publish a wealth of information about technical
tradecraft that people can use to counteract much of the eavesdropping
that takes place in modern society, most of this is simple, but also
will be quite startling to a lot of folks.
Enjoy the FBI documents.
