Security, trust and confidence can certainly be considered as the most important parts of the Information Society. Being protected when working, learning, shopping or doing any kind of e-commerce is of great value to citizens, students, business people, employees and employers. Commercial companies and their clients want to do business over the Internet in a secure way; business managers when having meetings by videoconferencing tools require the exchanged information to be protected; the publishing industry is concerned with the protection of copyright; hospital patients have a right to privacy; etc. There is no area in the Information Society that can proliferate without extensive use of services that provide satisfactory protection and privacy of data or personality.

In addition, the subject matter supports aspiring security engineers to forge a career path to successfully manage a security program, thereby adding value and reducing risk to the business. Readers learn how to translate technical challenges into business requirements, understand when to "go big or go home," explore in-depth defense strategies, and review tactics on when to absorb risks. This book explains how to properly plan and implement an infosec program based on business strategy and results.

Enterprise Level Security 2: Advanced Topics in an Uncertain World follows on from the authors' first book on Enterprise Level Security (ELS), which covered the basic concepts of ELS and the discoveries made during the first eight years of its development. This book follows on from this to give a discussion of advanced topics and solutions, derived from 16 years of research, pilots, and operational trials in putting an enterprise system together. The chapters cover specific advanced topics derived from painful mistakes and numerous revisions of processes. This book covers many of the topics omitted from the first book including multi-factor authentication, cloud key management, enterprise change management, entity veracity, homomorphic computing, device management, mobile ad hoc, big data, mediation, and several other topics. The ELS model of enterprise security is endorsed by the Secretary of the Air Force for Air Force computing systems and is a candidate for DoD systems under the Joint Information Environment Program. The book is intended for enterprise IT architecture developers, application developers, and IT security professionals. This is a unique approach to end-to-end security and fills a niche in the market.

In 1775, Paul Revere, the folk hero of the American Revolution, galloped wildly on horseback through small towns to warn American colonists that the British were coming. In today's Internet age, how do we warn vast numbers of computers about impending cyber attacks?

Rapid and widespread dissemination of security updates throughout the Internet would be invaluable for many purposes, including sending early-warning signals, distributing new virus signatures, updating certificate revocation lists, dispatching event information for intrusion detection systems, etc. However, notifying a large number of machines securely, quickly, and with high assurance is very challenging. Such a system must compete with the propagation of threats, handle complexities in large-scale environments, address interruption attacks toward dissemination, and also secure itself.

Disseminating Security Updates at Internet Scale describes a new system, "Revere," that addresses these problems. "Revere" builds large-scale, self-organizing and resilient overlay networks on top of the Internet to push security updates from dissemination centers to individual nodes. "Revere" also sets up repository servers for individual nodes to pull missed security updates. This book further discusses how to protect this push-and-pull dissemination procedure and how to secure "Revere" overlay networks, considering possible attacks and countermeasures. Disseminating Security Updates at Internet Scale presents experimental measurements of a prototype implementation of "Revere" gathered using a large-scale oriented approach. These measurements suggest that "Revere" can deliver security updates at the required scale, speed and resiliency for a reasonable cost.

Disseminating Security Updates at Internet Scale is designed to meet the needs of researchers and practitioners in industry and graduate students in computer science. This book will also be helpful to those trying to design peer systems at large scale when security is a concern, since many of the issues faced by these designs are also faced by "Revere." The "Revere" solutions may not always be appropriate for other peer systems with very different goals, but the analysis of the problems and possible solutions discussed here will be helpful in designing a customized approach for such systems.

IT Governance is finally getting the Board's and top management's attention. The value that IT needs to return and the associated risks that need to be managed, have become so important in many industries that enterprise survival depends on it. Information integrity is a significant part of the IT Governance challenge. Among other things, this conference will explore how Information Integrity contributes to the overall control and governance frameworks that enterprises need to put in place for IT to deliver business value and for corporate officers to be comfortable about the IT risks the enterprise faces. The goals for this international working conference are to find answers to the following questions: * what precisely do business managers need in order to have confidence in the integrity of their information systems and their data; * what is the status quo of research and development in this area; * where are the gaps between business needs on the one hand and research I development on the other; what needs to be done to bridge these gaps. The contributions have been divided in the following sections: * Refereed papers. These are papers that have been selected through a blind refereeing process by an international programme committee. * Invited papers. Well known experts present practice and research papers upon invitation by the programme committee. * Tutorial. Two papers describe the background, status quo and future development of CobiT as well as a case of an implementation of Co biT.

It discusses topics ranging from information theory-based security to coding for security and cryptography, and presents cutting-edge research and innovative findings from leading researchers. The characteristic feature of all the contributions in this book is their relevance for the practical application of security principles to a variety of widely used communication techniques, including: multiantenna systems, ultra-wide-band communication systems, power line communications, and quantum key distribution techniques. A further distinctive aspect is the attention paid to both unconditional and computational security techniques, building a bridge between two usually distinct worlds. The book gathers extended versions of contributions delivered at the Second Workshop on Communication Security, held in Paris, France, in April 2017 and affiliated with the conference EUROCRYPT 2017.

Cryptography has experienced rapid development, with major advances recently in both secret and public key ciphers, cryptographic hash functions, cryptographic algorithms and multiparty protocols, including their software engineering correctness verification, and various methods of cryptanalysis. This textbook introduces the reader to these areas, offering an understanding of the essential, most important, and most interesting ideas, based on the authors' teaching and research experience.

After introducing the basic mathematical and computational complexity concepts, and some historical context, including the story of Enigma, the authors explain symmetric and asymmetric cryptography, electronic signatures and hash functions, PGP systems, public key infrastructures, cryptographic protocols, and applications in network security. In each case the text presents the key technologies, algorithms, and protocols, along with methods of design and analysis, while the content is characterized by a visual style and all algorithms are presented in readable pseudocode or using simple graphics and diagrams.

The book is suitable for undergraduate and graduate courses in computer science and engineering, particularly in the area of networking, and it is also a suitable reference text for self-study by practitioners and researchers. The authors assume only basic elementary mathematical experience, the text covers the foundational mathematics and computational complexity theory.

The first part of this book covers the key concepts of cryptography on an undergraduate level, from encryption and digital signatures to cryptographic protocols. Essential techniques are demonstrated in protocols for key exchange, user identification, electronic elections and digital cash. In the second part, more advanced topics are addressed, such as the bit security of one-way functions and computationally perfect pseudorandom bit generators. The security of cryptographic schemes is a central topic. Typical examples of provably secure encryption and signature schemes and their security proofs are given. Though particular attention is given to the mathematical foundations, no special background in mathematics is presumed. The necessary algebra, number theory and probability theory are included in the appendix. Each chapter closes with a collection of exercises. In the second edition the authors added a complete description of the AES, an extended section on cryptographic hash functions, and new sections on random oracle proofs and public-key encryption schemes that are provably secure against adaptively-chosen-ciphertext attacks. The third edition is a further substantive extension, with new topics added, including: elliptic curve cryptography; Paillier encryption; quantum cryptography; the new SHA-3 standard for cryptographic hash functions; a considerably extended section on electronic elections and Internet voting; mix nets; and zero-knowledge proofs of shuffles. The book is appropriate for undergraduate and graduate students in computer science, mathematics, and engineering.

The book deals with the management of information systems security and privacy, based on a model that covers technological, organizational and legal views. This is the basis for a focused and methodologically structured approach that presents "the big picture" of information systems security and privacy, while targeting managers and technical profiles. The book addresses principles in the background, regardless of a particular technology or organization. It enables a reader to suit these principles to an organization's needs and to implement them accordingly by using explicit procedures from the book. Additionally, the content is aligned with relevant standards and the latest trends. Scientists from social and technical sciences are supposed to find a framework for further research in this broad area, characterized by a complex interplay between human factors and technical issues.

This book provides an opportunity for investigators, government officials, systems scientists, strategists, assurance researchers, owners, operators and maintainers of large, complex and advanced systems and infrastructures to update their knowledge with the state of best practice in the challenging domains whilst networking with the leading representatives, researchers and solution providers. Drawing on 12 years of successful events on information security, digital forensics and cyber-crime, the 13th ICGS3-20 conference aims to provide attendees with an information-packed agenda with representatives from across the industry and the globe. The challenges of complexity, rapid pace of change and risk/opportunity issues associated with modern products, systems, special events and infrastructures. In an era of unprecedented volatile, political and economic environment across the world, computer-based systems face ever more increasing challenges, disputes and responsibilities, and whilst the Internet has created a global platform for the exchange of ideas, goods and services, it has also created boundless opportunities for cyber-crime. As an increasing number of large organizations and individuals use the Internet and its satellite mobile technologies, they are increasingly vulnerable to cyber-crime threats. It is therefore paramount that the security industry raises its game to combat these threats. Whilst there is a huge adoption of technology and smart home devices, comparably, there is a rise of threat vector in the abuse of the technology in domestic violence inflicted through IoT too. All these are an issue of global importance as law enforcement agencies all over the world are struggling to cope.

The intersection of politics, law, privacy, and security in the context of computer technology is both sensitive and complex. Computer viruses, worms, Trojan horses, spyware, computer exploits, poorly designed software, inadequate technology laws, politics and terrorism - all of these have a profound effect on our daily computing operations and habits, with major political and social implications.""Computer Security, Privacy and Politics"" connects privacy and politics, offering a point-in-time review of recent developments of computer security, with a special focus on the relevance and implications of global privacy, law, and politics for society, individuals, and corporations. An estimable addition to any library collection, this Premier Reference Source compiles high quality, timely content on such cutting-edge topics as reverse engineering of software, understanding emerging computer exploits, emerging lawsuits and cases, global and societal implications, and protection from attacks on privacy.

Security without Obscurity: Frequently Asked Questions (FAQ) complements Jeff Stapleton's three other Security without Obscurity books to provide clear information and answers to the most commonly asked questions about information security (IS) solutions that use or rely on cryptography and key management methods. There are good and bad cryptography, bad ways of using good cryptography, and both good and bad key management methods. Consequently, information security solutions often have common but somewhat unique issues. These common and unique issues are expressed as an FAQ organized by related topic areas. The FAQ in this book can be used as a reference guide to help address such issues. Cybersecurity is based on information technology (IT) that is managed using IS controls, but there is information, misinformation, and disinformation. Information reflects things that are accurate about security standards, models, protocols, algorithms, and products. Misinformation includes misnomers, misunderstandings, and lack of knowledge. Disinformation can occur when marketing claims either misuse or abuse terminology, alluding to things that are inaccurate or subjective. This FAQ provides information and distills misinformation and disinformation about cybersecurity. This book will be useful to security professionals, technology professionals, assessors, auditors, managers, and hopefully even senior management who want a quick, straightforward answer to their questions. It will serve as a quick reference to always have ready on an office shelf. As any good security professional knows, no one can know everything.

This monograph describes and implements partially homomorphic encryption functions using a unified notation. After introducing the appropriate mathematical background, the authors offer a systematic examination of the following known algorithms: Rivest-Shamir-Adleman; Goldwasser-Micali; ElGamal; Benaloh; Naccache-Stern; Okamoto-Uchiyama; Paillier; Damgaard-Jurik; Boneh-Goh-Nissim; and Sander-Young-Yung. Over recent years partially and fully homomorphic encryption algorithms have been proposed and researchers have addressed issues related to their formulation, arithmetic, efficiency and security. Formidable efficiency barriers remain, but we now have a variety of algorithms that can be applied to various private computation problems in healthcare, finance and national security, and studying these functions may help us to understand the difficulties ahead. The book is valuable for researchers and graduate students in Computer Science, Engineering, and Mathematics who are engaged with Cryptology.

Information Hiding: Steganography and Watermarking - Attacks and Countermeasures deals with information hiding. With the proliferation of multimedia on the Internet, information hiding addresses two areas of concern: privacy of information from surveillance (steganography) and protection of intellectual property (digital watermarking). Steganography (literally, covered writing) explores methods to hide the existence of hidden messages. These methods include invisible ink, microdot, digital signature, covert channel, and spread spectrum communication. Digital watermarks represent a commercial application of steganography. Watermarks can be used to track the copyright and ownership of electronic media. In this volume, the authors focus on techniques for hiding information in digital media. They analyze the hiding techniques to uncover their limitations. These limitations are employed to devise attacks against hidden information. The goal of these attacks is to expose the existence of a secret message or render a digital watermark unusable. In assessing these attacks, countermeasures are developed to assist in protecting digital watermarking systems. Understanding the limitations of the current methods will lead us to build more robust methods that can survive various manipulation and attacks. The more information that is placed in the public's reach on the Internet, the more owners of such information need to protect themselves from theft and false representation. Systems to analyze techniques for uncovering hidden information and recover seemingly destroyed information will be useful to law enforcement authorities in computer forensics and digital traffic analysis. Information Hiding: Steganography and Watermarking - Attacks and Countermeasures presents the authors' research contributions in three fundamental areas with respect to image-based steganography and watermarking: analysis of data hiding techniques, attacks against hidden information, and countermeasures to attacks against digital watermarks. Information Hiding: Steganography and Watermarking &endash; Attacks and Countermeasures is suitable for a secondary text in a graduate level course, and as a reference for researchers and practitioners in industry.

This book focuses on the different representations and cryptographic properties of Booleans functions, presents constructions of Boolean functions with some good cryptographic properties. More specifically, Walsh spectrum description of the traditional cryptographic properties of Boolean functions, including linear structure, propagation criterion, nonlinearity, and correlation immunity are presented. Constructions of symmetric Boolean functions and of Boolean permutations with good cryptographic properties are specifically studied. This book is not meant to be comprehensive, but with its own focus on some original research of the authors in the past. To be self content, some basic concepts and properties are introduced. This book can serve as a reference for cryptographic algorithm designers, particularly the designers of stream ciphers and of block ciphers, and for academics with interest in the cryptographic properties of Boolean functions.

In recent years, the tremendous advancement of digital technology has increased the ease with which digital multimedia files are stored, transmitted, and reproduced. Because traditional copyright methods are unsuitable for establishing ownership, digital watermarking is considered one of the best solutions to prevent illegal and malicious copying and distribution of digital media. Advanced Techniques in Multimedia Watermarking: Image, Video and Audio Applications introduces readers to state-of-the-art research in multimedia watermarking. Covering new advancements in digital image watermarking and techniques for implementation and optimization across different media, this book is a valuable companion for professionals and researchers working in areas such as document watermarking, multimedia fingerprinting, information hiding, secured e-commerce, copyright protection, and hardware implementation of real-time multimedia watermarking.
