Security and Privacy in Computer Systems
Wiley 1973
ISBN 0471 40611 2
This book covers publicly-available crypto of the period (looks very weak now)
and "rings" by Robert Graham and civil liberties threats involving data
storage and aggregation.

Passive infiltraton may be accomplished by wiretapping or by electomagnetic
pickup of the traffic at any point in the system. Although considerable
effort has been applied to counter such threats to defense communications,
nongovernmental approaches to information privacy usually assume that
communication lines are secure, when in fact they are one of the most
vulnerable parts of the system.
Page 84
In addition to the spectrum of threats arising from wiretapping, electro-
magnetic radiation from terminals myst be considered.[12] Electromagnetic
radiation characteristics will depend heavily on the type of terminal,
and may in some cases pose serious shielding and electrical-filtering
problems. More advanced terminals using cathode ray tube for information
display may create even greater problems in trying to prevent what has been
called "tuning in the terminal on Channel 4."

Another chapter has (starting on page 101) a section called "THE PARADOX OF
THE SECRECY ABOUT SECRECY" where it says:
It should be noted that this Memorandum has been purposely written to be
unclassified ... the only background information used is that found in the
unclassified literature ...
So can anyone say whether there are interesting things in that ref 12 ?
