This book discusses and summarizes current research issues identifies challenges and outlines
future directions for proactive and dynamic network defense. This book also presents the latest
fundamental research results toward understanding proactive and dynamic network defense by top
researchers in related areas. It includes research results that offer formal frameworks to
define proactive and dynamic network defense and develop novel models to analyze and evaluate
proactive designs and strategies in computer systems network systems cyber-physical systems
and wireless networks. A wide variety of scientific techniques have been highlighted to study
these problems in the fundamental domain. As the convergence of our physical and digital worlds
grows fast pace protecting information systems from being tampered or unauthorized access is
becoming one of the most importance issues. The traditional mechanisms of network defense are
built upon a static passive and reactive nature which has insufficient to defend against
today's attackers that attempt to persistently analyze probe circumvent or fool such
mechanisms. It has not yet been fully investigated to address the early stage of cyber kill
chain when adversaries carry out sophisticated reconnaissance to plan attacks against a defense
system. Recently proactive and dynamic network defense has been proposed as an important
alternative towards comprehensive network defense. Two representative types of such defense are
moving target defense (MTD) and deception-based techniques. These emerging approaches show
great promise to proactively disrupt the cyber-attack kill chain and are increasingly gaining
interest within both academia and industry. However these approaches are still in their
preliminary design stage. Despite the promising potential there are research issues yet to be
solved regarding the effectiveness efficiency costs and usability of such approaches. In
addition it is also necessary to identify future research directions and challenges which is
an essential step towards fully embracing proactive and dynamic network defense.This book will
serve as a great introduction for advanced-level computer science and engineering students who
would like to start R&D efforts in the field of proactive and dynamic network defense.
Researchers and professionals who work in this related field will also find this book useful as
a reference.
