Executive residence inspections |
Which location is most vulnerable for corporate
secrets? THE EXECUTIVE RESIDENCE.
In our experience, this is the corporate soft spot.
FM cordless phones, analog phone-digital telephone
lines, answering machines, baby monitors etc.
combine to cause the problem.
We recommend a survey of an executive residence in
conjunction with the corporate office “post sweep”.
There is great value in an inspection that
highlights potential problems. For example, if an
easily intercepted cordless phone is being used, the
recommendation that it be replaced with a spread
spectrum model that cannot easily be monitored.
One of our corporate clients had an innovative
solution to the analog cordless phone problem. They
purchased a dozen secure, digital cordless, spread
spectrum telephones which were switched with the
executives non-secure analog cordless telephones.
Two technicians can complete this sweep in about
four hours. The first part of the sweep is spent
looking for radio and video signals. Then, they open
and examine the telephones and trace the wiring. The
physical inspection is concentrated in the living
area. When the inspection is completed the homeowner
or his representative is debriefed. Our discussion
with the homeowner includes information on a broad
range of security issues as appropriate. Common
items include physical security, shredders, analog
cell phones, and safe storage of handguns and how to
identify possible surveillance of the residence.
During an inspection of home answering machines we
explain how they may be used to eavesdrop on
conversations. In one recent inspection we
demonstrated how the answering machine would
intercept conversations. An unknown person had asked
the housecleaner about the family schedules. This
was followed by a break-in where nothing was taken.
Following the break-in conversations from the
residence were being repeated at work. During our
demonstration the homeowner recognized the letters
“RM” on the display indicating that the machine was
in the remote monitor mode. The homeowner said, "I
have seen that RM display before!"
In a different residential survey we found an
answering machine problem in a fax machine. The
all-purpose device was being used to monitor our
client's home office.
Telephone lines are traced and tested from the
instruments to the telephone interface block
generally located at the exterior of the residence.
In one survey this unsecured interface block was
inspected and a radio transmitter was found. In
several others we have found “cross-over” wiring,
which facilitated an on-going line transmission of
signals outside the residence.
A more in-depth home inspection is performed if
specific issues are being investigated. |
