The Internet, as well as other telecommunication networks and information systems, have become an integrated part of our daily lives, and our dependency upon their underlying infrastructure is ever-increasing. Unfortunately, as our dependency has grown, so have hostile attacks on the cyber infrastructure by network predators. The lack of security as a core element in the initial design of these information systems has made common desktop software, infrastructure services, and information networks increasingly vulnerable to continuous and innovative breakers of security. Worms, viruses, and spam are examples of attacks that cost the global economy billions of dollars in lost productivity. Sophisticated distributed denial of service (DDoS) attacks that use thousands of web robots (bots) on the Internet and telecommunications networks are on the rise. The ramifications of these attacks are clear: the potential for a devastating largescale network failure, service interruption, or the total unavailability of service. Yet many security programs are based solely on reactive measures, such as the patching of software or the detection of attacks that have already occurred, instead of proactive measures that prevent attacks in the first place. Most of the network security configurations are performed manually and require experts to monitor, tune security devices, and recover from attacks. On the other hand, attacks are getting more sophisticated and highly automated, which gives the attackers an advantage in this technology race. A key contribution of this book is that it provides an integrated view and a comprehensive framework of the various issues relating to cyber infrastructure protection. It covers not only strategy and policy issues, but it also covers social, legal, and technical aspects of cyber security as well. We strongly recommend this book for policymakers and researchers so that they may stay abreast of the latest research and develop a greater understanding of cyber security issues.

Are our networked societies really vulnerable, as some have suggested, to a knock-out blow, perpetrated by state-sponsored hackers or terrorists? And what can be done to defend the state from this and from the encroachment of external networks that transcend its borders and breach its laws?
This Adelphi tackles the range of issues raised by our dependence on digital networks. It considers how instantaneous, global communications are challenging national and social orders and what shape those challenges may take as the net is cast ever wider. Comparing the transformations of the Information Age with those of previous generations, when new technologies and emerging transnational threats spread panic in political and strategic circles, the authors examine the real implications for states and statehood.

‘In the cyber domain, policy has fallen far behind technology and operational art. By providing a conceptual framework for looking at what power is in the cyber domain and how it is exercised, this book offers policy-makers valuable guidance in how to think about a major security issue.’ Michael Hayden, Director of the CIA, 2006–09
‘Cyberspace offers a wealth of threats, benefits and opportunities for governments, business and the citizen. This book provides a stimulating contribution to the policy debate around cyber.’ Iain Lobban CB, Director, GCHQ (Government Communications Headquarters)

Traditional intrusion detection and logfile analysis are no longer enough to protect today’s complex networks. In this practical guide, security researcher Michael Collins shows you several techniques and tools for collecting and analyzing network traffic datasets. You’ll understand how your network is used, and what actions are necessary to protect and improve it.
Divided into three sections, this book examines the process of collecting and organizing data, various tools for analysis, and several different analytic scenarios and techniques. It’s ideal for network administrators and operational security analysts familiar with scripting.Explore network, host, and service sensors for capturing security dataStore data traffic with relational databases, graph databases, Redis, and HadoopUse SiLK, the R language, and other tools for analysis and visualizationDetect unusual phenomena through Exploratory Data Analysis (EDA)Identify significant structures in networks with graph analysisDetermine the traffic that’s crossing service ports in a networkExamine traffic volume and behavior to spot DDoS and database raidsGet a step-by-step process for network mapping and inventory
The worldwide reach of the Internet allows malicious cyber criminals to coordinate and launch attacks on both cyber and cyber-physical infrastructure from anywhere in the world. This purpose of this handbook is to introduce the theoretical foundations and practical solution techniques for securing critical cyber and physical infrastructures as well as their underlying computing and communication architectures and systems. Examples of such infrastructures include utility networks (e.g., electrical power grids), ground transportation systems (automotives, roads, bridges and tunnels), airports and air traffic control systems, wired and wireless communication and sensor networks, systems for storing and distributing water and food supplies, medical and healthcare delivery systems, as well as financial, banking and commercial transaction assets. The handbook focus mostly on the scientific foundations and engineering techniques – while also addressing the proper integration of policies and access control mechanisms, for example, how human-developed policies can be properly enforced by an automated system.
*Addresses the technical challenges facing design of secure infrastructures by providing examples of problems and solutions from a wide variety of internal and external attack scenarios
