EVOLVING NETWORKING TECHNOLOGIES This book discusses in a practical
manner some of the critical security challenges facing the
ever-evolving networking technologies of today. In an age of
explosive worldwide growth of electronic data storage and
communications, effective protection of information has become a
critical requirement, especially when used in coordination with
other tools for information security and cryptography in all of its
applications, including data confidentiality, data integrity, and
user authentication. While the importance of cryptographic
technique, i.e., encryption, in protecting sensitive and critical
information and resources cannot be overemphasized, an examination
of the technical evolution within several industries reveals an
approaching precipice of scientific change. The glacially paced but
inevitable convergence of quantum mechanics, nanotechnology,
computer science, and applied mathematics will revolutionize modern
technology. The implications of such changes will be far-reaching,
with one of its greatest impacts affecting information security
and, more specifically, modern cryptography. The book takes the
reader through these issues. As the security systems design becomes
more and more complex to meet these challenges, a mistake that is
committed most often by security specialists is not making a
comprehensive analysis of the system to be secured before choosing
which security mechanism to deploy. Often, the security mechanism
chosen turns out to be either incompatible with, or inadequate for,
handling the complexities of the system. In addition, the book also
discusses three main points: Configuration management is a critical
issue, and as networks are increasing in size, their configuration
needs to be managed. Devices may conflict with each other in terms
of configuration. Therefore, it becomes challenging for firewalls
to be up-to-date according to network policies. Scalability of the
network is another big challenge, it would be easier to address if
the network stays the same, but the network is ever expanding with
a constant increase in the number of devices devoted to the
network. Vendor lock-in: Business decisions that are taken today
are revolving around the assumptions and capabilities of the
current vendor and environment scenario. Buying the best solutions
from today’s vendors involves how to interoperate, integrate, and
support multiple solutions. It may involve tearing out all of the
longstanding kits without tearing down the entire network at the
same time. Audience This book specifically appeals to industry
practitioners, IT researchers, and students regarding network
technological management.
