Technology is taking us to a world where myriads of heavily networked devices interact with the physical world in multiple ways and at multiple scales, from the global Internet down to micro and nano devices. Many of these devices are highly mobile and must adapt to the surrounding environment in a totally unsupervised way. A fundamental research challenge is the design of robust decentralized computing systems that are capable of operating under changing environments and noisy input, and yet exhibit the desired behavior and response time, under constraints such as energy consumption, size, and processing power. Biological systems are able to handle many of these challenges with an elegance and efficiency still far beyond current human artifacts. The goal is to obtain methods on how to engineer technical systems, which have similar high stability and efficiency. With this book, we present a comprehensive overview of the most promising research directions in the area of bio-inspired computing. According to the broad spectrum addressed by the different book chapters, a rich variety of biological principles and their application to ICT systems are presented.

As this book demonstrates, service-oriented architecture (SOA) is finally becoming a concrete discipline rather than a hopeful collection of cloud charts. Based on the author´s experience rolling out an SOA at a major mobile phone company, SOA in Practice explains how SOA can simplify the creation of large-scale applications. Whether your project involves a large set of web service-based components, or is a means to connect legacy applications to more modern workflows, this book clarifies how - and whether - SOA fits your needs. In fact, this is the only book that gives you a real understanding of what SOA is about, offering a fundamental overview of what it means to realize SOA in practice without getting lost in theory. After defining SOA´s many facets, examining typical use patterns, and exploring how loose coupling helps build stronger applications, Josuttis presents a framework to help you determine when to take advantage of SOA. With SOA in Practice, you will: - Focus squarely on real deployment and technology, not just standards maps - Examine business problems to determine which ones fit an SOA approach before plastering an SOA solution on top of them - Get concrete paths for building solutions without getting trapped in the mire of changing web services details - Gain the experience of a systems analyst intimately involved with SOA Earlier books on SOA suffered from too much vision and not enough reality. This one describes the real-world problems of implementing and running an SOA in practice. Not only will you learn how to categorize different SOA layers and different SOA stages of extension, you´ll learn how performance, security, and other real-life aspects influence the business case of SOA and the way a SOA is realized.If you´re serious about SOA, rely on the experience of someone who´s been in the trenches and achieved success. You´ll find it with SOA in Practice. This book demonstrates service-oriented architecture (SOA) as a concrete discipline rather than a hopeful collection of cloud charts. Built upon the author´s firsthand experience rolling out a SOA at a major corporation, SOA in Practice explains how SOA can simplify the creation and maintenance of large-scale applications.

This book reviews the use of digital surveillance for detecting, investigating and interpreting fraud associated with critical cyberinfrastructures in Nigeria, as it is well known that the country´s cyberspace and cyberinfrastructures are very porous, leaving too much room for cyber-attackers to freely operate. In 2017, there were 3,500 successful cyber-attacks on Nigerian cyberspace, which led to the country losing an estimated 450 million dollars. These cybercrimes are hampering Nigeria´s digital economy, and also help to explain why many Nigerians remain skeptical about Internet marketing and online transactions. If sensitive conversations using digital devices are not well monitored, Nigeria will be vulnerable to cyber-warfare, and its digital economy, military intelligence, and related sensitive industries will also suffer. The Nigerian Army Cyber Warfare Command was established in 2018 in order to combat terrorism, banditry, and other attacks by criminal groups in Nigeria. However, there remains an urgent need to produce digital surveillance software to help law enforcement agencies in Nigeria to detect and prevent these digitally facilitated crimes. The monitoring of Nigeria´s cyberspace and cyberinfrastructure has become imperative, given that the rate of criminal activities using technology has increased tremendously. In this regard, digital surveillance includes both passive forensic investigations (where an attack has already occurred) and active forensic investigations (real-time investigations that track attackers). In addition to reviewing the latest mobile device forensics, this book covers natural laws (Benford´s Law and Zipf´s Law) for network traffic analysis, mobile forensic tools, and digital surveillance software (e.g., A-BOT). It offers valuable insights into how digital surveillance software can be used to detect and prevent digitally facilitated crimes in Nigeria, and highlights the benefits of adopting digital surveillance software in Nigeria and other countries facing the same issues.

IoT Security Issues looks at the burgeoning growth of devices of all kinds controlled over the Internet of all varieties, where product comes first and security second. In this case, security trails badly. This book examines the issues surrounding these problems, vulnerabilities, what can be done to solve the problem, investigating the stack for the roots of the problems and how programming and attention to good security practice can combat the problems today that are a result of lax security processes on the Internet of Things. This book is for people interested in understanding the vulnerabilities on the Internet of Things, such as programmers who have not yet been focusing on the IoT, security professionals and a wide array of interested hackers and makers. This book assumes little experience or knowledge of the Internet of Things. To fully appreciate the book, limited programming background would be helpful for some of the chapters later in the book, though the basic content is explained. The author, Alasdair Gilchrist, has spent 25 years as a company director in the fields of IT, Data Communications, Mobile Telecoms and latterly Cloud/SDN/NFV technologies, as a professional technician, support manager, network and security architect. He has project-managed both agile SDLC software development as well as technical network architecture design. He has experience in the deployment and integration of systems in enterprise, cloud, fixed/mobile telecoms, and service provider networks. He is therefore knowledgeable in a wide range of technologies and has written a number of books in related fields.
