A Multidisciplinary Introduction To Information Security

With most services and products now being offered through digital communications, new challenges have emerged for information security specialists. A Multidisciplinary Introduction to Information Security presents a range of topics on the security, privacy, and safety of information and communication technology. It brings together methods in pure mathematics, computer and telecommunication sciences, and social sciences. The book begins with the cryptographic algorithms of the Advanced Encryption Standard (AES) and Rivest, Shamir, and Adleman (RSA). It explains the mathematical reasoning behind public key cryptography and the properties of a cryptographic hash function before presenting the principles and examples of quantum cryptography. The text also describes the use of cryptographic primitives in the communication process, explains how a public key infrastructure can mitigate the problem of crypto-key distribution, and discusses the security problems of wireless network access. After examining past and present protection mechanisms in the global mobile telecommunication system, the book proposes a software engineering practice that prevents attacks and misuse of software. It then presents an evaluation method for ensuring security requirements of products and systems, covers methods and tools of digital forensics and computational forensics, and describes risk assessment as part of the larger activity of risk management. The final chapter focuses on information security from an organizational and people point of view. As our ways of communicating and doing business continue to shift, information security professionals must find answers to evolving issues. Offering a starting point for more advanced work in the field, this volume addresses various security and privacy problems and solutions related to the latest information and communication technology.

With the prevalence of digital information, IT professionals have encountered new challenges regarding data security. In an effort to address these challenges and offer solutions for securing digital information, new research on cryptology methods is essential. Multidisciplinary Perspectives in Cryptology and Information Security considers an array of multidisciplinary applications and research developments in the field of cryptology and communication security. This publication offers a comprehensive, in-depth analysis of encryption solutions and will be of particular interest to IT professionals, cryptologists, and researchers in the field.

This book provides an introduction to the basic ideas involved in cybersecurity, whose principal aim is protection of IT systems against unwanted behaviour mediated by the networks which connect them. Due to the widespread use of the Internet in modern society for activities ranging from social networking and entertainment to distribution of utilities and public administration, failures of cybersecurity can threaten almost all aspects of life today. Cybersecurity is a necessity in the modern world, where computers and other electronic devices communicate via networks, and breakdowns in cybersecurity cost society many resources. The aims of cybersecurity are quite simple: data must not be read, modified, deleted or made unavailable by persons who are not allowed to. To meet this major challenge successfully in the digitally interconnected world, one needs to master numerous disciplines because modern IT systems contain software, cryptographic modules, computing units, networks, and human users—all of which can influence the success or failure in the effort. Topics and features: Introduces readers to the main components of a modern IT system: basic hardware, networks, operating system, and network-based applications Contains numerous theoretical and practical exercises to illustrate important topics Discusses protective mechanisms commonly used to ensure cybersecurity and how effective they are Discusses the use of cryptography for achieving security in IT systems Explains how to plan for protecting IT systems based on analysing the risk of various forms of failure Illustrates how human users may affect system security and ways of improving their behaviour Discusses what to do if a security failure takes place Presents important legal concepts relevant for cybersecurity, including the concept of cybercrime This accessible, clear textbook is intended especially for students starting a relevant course in computer science or engineering, as well as for professionals looking for a general introduction to the topic. Dr. Robin Sharp is an emeritus professor in the Cybersecurity Section at DTU Compute, the Dept. of Applied Mathematics and Computer Science at the Technical University of Denmark (DTU).

Digital information and data processing, storage and transmission are already at the core of most modern enterprises and most individuals have significant digital footprints. Computer-based information networks operating in cyber-space (interconnected on the Internet) are at the core of modern businesses many of which operate across countries and continents. Government and human development enterprises (health, education, etc.) depend critically on Internet-based operations. The traditional systems of in-house applications and data storage are rapidly being replaced by shared or independent Cloud services. However, these highly beneficial developments in information technology also come with a variety of cyber-threats. The risks may originate from personal cyber-habits, employees, clients and contractors, or external cyber-criminals; they may result from deliberate acts or human errors. Irrespective of the source or cause, the consequences can be devastating, ranging valuable or sensitive data loss, or disruption of operations of sensitive infrastructure. Cyber-crime is increasingly weaponized to extract ransom payment or cripple sensitive infrastructure of enemy nation states. Cyber-security has emerged as a major technology discipline and, with the exponential rate of personal and corporate migration to cyber-space, incidents of cyber-crime are projected to grow at a similar rate. This introductory book presents a comprehensive overview of the digital cyber-space, evaluation of the extent of cyber-threats, the critical information technology practices and infrastructure that facilitate cyber-attacks, the main criminal actors and their strategies, and current status and trends in cyber-defense strategies for protecting the digital world.

Cyber-attacks continue to rise as more individuals rely on storing personal information on networks. Even though these networks are continuously checked and secured, cybercriminals find new strategies to break through these protections. Thus, advanced security systems, rather than simple security patches, need to be designed and developed. Exploring Security in Software Architecture and Design is an essential reference source that discusses the development of security-aware software systems that are built into every phase of the software architecture. Featuring research on topics such as migration techniques, service-based software, and building security, this book is ideally designed for computer and software engineers, ICT specialists, researchers, academicians, and field experts.

What Is Combinatorics Anyway? Broadly speaking, combinatorics is the branch of mathematics dealing with different ways of selecting objects from a set or arranging objects. It tries to answer two major kinds of questions, namely, counting questions: how many ways can a selection or arrangement be chosen with a particular set of properties; and structural questions: does there exist a selection or arrangement of objects with a particular set of properties? The authors have presented a text for students at all levels of preparation. For some, this will be the first course where the students see several real proofs. Others will have a good background in linear algebra, will have completed the calculus stream, and will have started abstract algebra. The text starts by briefly discussing several examples of typical combinatorial problems to give the reader a better idea of what the subject covers. The next chapters explore enumerative ideas and also probability. It then moves on to enumerative functions and the relations between them, and generating functions and recurrences., Important families of functions, or numbers and then theorems are presented. Brief introductions to computer algebra and group theory come next. Structures of particular interest in combinatorics: posets, graphs, codes, Latin squares, and experimental designs follow. The authors conclude with further discussion of the interaction between linear algebra and combinatorics. Features Two new chapters on probability and posets. Numerous new illustrations, exercises, and problems. More examples on current technology use A thorough focus on accuracy Three appendices: sets, induction and proof techniques, vectors and matrices, and biographies with historical notes, Flexible use of MapleTM and MathematicaTM

Cryptology, the mathematical and technical science of ciphers and codes, and philology, the humanistic study of natural or human languages, are typically understood as separate domains of activity. But Brian Lennon contends that these two domains, both concerned with authentication of text, should be viewed as contiguous. He argues that computing’s humanistic applications are as historically important as its mathematical and technical ones. What is more, these humanistic uses, no less than cryptological ones, are marked and constrained by the priorities of security and military institutions devoted to fighting wars and decoding intelligence. Lennon’s history encompasses the first documented techniques for the statistical analysis of text, early experiments in mechanized literary analysis, electromechanical and electronic code-breaking and machine translation, early literary data processing, the computational philology of late twentieth-century humanities computing, and early twenty-first-century digital humanities. Throughout, Passwords makes clear the continuity between cryptology and philology, showing how the same practices flourish in literary study and in conditions of war. Lennon emphasizes the convergence of cryptology and philology in the modern digital password. Like philologists, hackers use computational methods to break open the secrets coded in text. One of their preferred tools is the dictionary, that preeminent product of the philologist’s scholarly labor, which supplies the raw material for computational processing of natural language. Thus does the historic overlap of cryptology and philology persist in an artifact of computing—passwords—that many of us use every day.
