Networked computing
applications are
increasingly challenged
by security concerns
-- concerns that
secrets may be
lost to competitors,
concerns that
hackers may intrude
into our business
networks, concerns
that someone may
compromise critical
resources.
These issues
are especially
critical where
wireless technology
comprises part
of the network
infrastructure.
A whole new class
of threat is introduced
with deliberately
radiated signals
that others may
receive, and open,
wireless receivers
that may be deceived
into accepting
undesired input
signals.
Securing
Your Wireless
Networks
presents a thorough
assessment of
the security threats
and challenges
that confront
the IT professional
and manager in
modern wireless
computing environments.
This short course
is designed to
improve the effectiveness
of IT professionals,
managers and security
officers by exposing
them to an extensive
review of networked
computing security
risks and treatment
of solution alternatives.
Anyone with a
professional interest
in knowing more
about the risks
to their wireless
computing environments
and the security
solutions which
are available
will benefit from
attending.
There are no
technical prerequisites
for this program,
other than an
assumed understanding
of networked computing
principles. Securing
Your Wireless
Networks has been
designed as a
freestanding treatment
of the subject
designed to complement
the accompanying
Mobile Computing
and wireless LANs
course. Students
will benefit from
attending this
earlier course,
but it is not
a prerequisite.
This course is
taught using several
classroom demonstration
labs, and whenever
feasible, includes
students experimenting
with WLAN configurations
and operation.
A permanent,
comprehensive
workbook is included
for each attendee
-- which provides
a work-along class
reference manual
with a cross-referenced,
comprehensive
subject index,
encyclopedic glossary
and recommended
reading catalog.
