Welcome to cyberspace - where all your computing and connection needs are on demand, and where security threats have never been more massive.A world without the advantages and convenience provided by cyberspace and the internet of things is now unimaginable. But do we truly grasp the threats to this massive, interconnected system? And do we really understand how to secure it? After all, cyber security is no longer just a technology problem; the effort to secure systems and society are now one and the same.This book discusses cyber security and cyber policy in an effort to improve the use and acceptance of security services. It argues that a substantive dialogue around cyberspace, cyber security and cyber policy is critical to a better understanding of the serious security issues we face.

This book presents a comprehensive overview of security issues in Cyber Physical Systems (CPSs), by analyzing the issues and vulnerabilities in CPSs and examining state of the art security measures. Furthermore, this book proposes various defense strategies including intelligent attack and anomaly detection algorithms. Today's technology is continually evolving towards interconnectivity among devices. This interconnectivity phenomenon is often referred to as Internet of Things (IoT). IoT technology is used to enhance the performance of systems in many applications. This integration of physical and cyber components within a system is associated with many benefits; these systems are often referred to as Cyber Physical Systems (CPSs). The CPSs and IoT technologies are used in many industries critical to our daily lives. CPSs have the potential to reduce costs, enhance mobility and independence of patients, and reach the body using minimally invasive techniques. Although this interconnectivity of devices can pave the road for immense advancement in technology and automation, the integration of network components into any system increases its vulnerability to cyber threats. Using internet networks to connect devices together creates access points for adversaries. Considering the critical applications of some of these devices, adversaries have the potential of exploiting sensitive data and interrupting the functionality of critical infrastructure. Practitioners working in system security, cyber security & security and privacy will find this book valuable as a reference. Researchers and scientists concentrating on computer systems, large-scale complex systems, and artificial intelligence will also find this book useful as a reference.

It includes a discussion of the challenges that analysts face when attempting to apply various network analysis techniques to criminal networks. Overall, it advances SNA as an investigative tool, and provides a significant contribution to the field that will be of interest to both researchers and practitioners interested in social network analysis, intelligence analysis and law enforcement.

Moreover, this book summarizes and discloses findings, inferences, and open challenges to inspire future research addressing theoretical and empirical aspects related to the imperative topic of IoT security. At least 20 billion devices will be connected to the Internet in the next few years. Many of these devices transmit critical and sensitive system and personal data in real-time. Collectively known as "the Internet of Things" (IoT), this market represents a $267 billion per year industry. As valuable as this market is, security spending on the sector barely breaks 1%. Indeed, while IoT vendors continue to push more IoT devices to market, the security of these devices has often fallen in priority, making them easier to exploit. This drastically threatens the privacy of the consumers and the safety of mission-critical systems. This book is intended for cybersecurity researchers and advanced-level students in computer science. Developers and operators working in this field, who are eager to comprehend the vulnerabilities of the Internet of Things (IoT) paradigm and understand the severity of accompanied security issues will also be interested in this book.

Any organization with valuable data has been or will be attacked, probably successfully, at some point and with some damage. And, don't all digitally connected organizations have at least some data that can be considered "valuable"? Cyber security is a big, messy, multivariate, multidimensional arena. A reasonable "defense-in-depth" requires many technologies; smart, highly skilled people; and deep and broad analysis, all of which must come together into some sort of functioning whole, which is often termed a security architecture.

Security is always a concern with any new technology. When we think security we typically think of stopping an attacker from breaking in or gaining access. However, based on the broad reach of wireless, stopping someone from passively listening is just as critical. Intrusion detection systems, firewalls, and forensics are just a few of the key areas that must be understood and applied to proactively solve the wireless problem. From short text messaging to war driving, Wireless Crime and Forensic Investigation explores all aspects of wireless technology, how it is used in daily life, and how it will be used in the future. The book provides a one-stop resource on the types of wireless crimes that are being committed and forensic investigation techniques for wireless devices and wireless networks. The author's straightforward and easy to read style seamlessly integrates the topics of wireless security and computer forensics. He provides a solid understanding of modern wireless technologies, wireless security techniques and wireless crime techniques, as well as conducting forensic analysis on wireless devices and networks. Each chapter, while part of a greater whole, can stand on its own, making researching wireless technologies, security, crime, or forensics easy. With a problem space as big and complex as wireless, proactive measures must be put in place, and put in place immediately. To protect your organization, you need to be well versed in the new technology sooner rather than later. You can pay now or you can pay later. Later always costs more. This book not only has all the information required to become proficient in wireless technology, but also provides the information required for conducting a forensic analysis in a wireless environment.
