Internetworking security has become a very big issue in recent months.
Companies who went through corporate life thinking, it will never happen
to me suddenly found themselves the victim of some sort of attack on
their network. High profile companies are most certainly a bigger target for
several reasons, including the notoriety the hacker receives for damaging
their network or Web site, and the amount of financial damage that can be
done by bringing down a successful e-commerce site. Recent attacks easily
racked up 100 million dollars in damage.
Is this issue anything new? Some may say yes, but the fact of the
matter is network security has always been a concern and hackers have
always been out there ready to prove themselves on your network. Most
hackers dont do it because of a specific vendetta against a company, but
because of the notoriety mentioned earlier. The best thing that you can do
is take charge of your network and set up security measures to ensure
that your company doesnt become an accomplishment on a hackers
resume.
This book will give you the information necessary to secure your internetwork
and the knowledge to identify possible problems that could arise
from each option. It will not only cover technologies and security design,
but also specific vendor products and tips for configuration. This book will
also include types of attacks that you can expect and ways that you can
safeguard your network against them. Remember, the worst thing that you
can do as a Network Administrator is nothing.
