Cryptology is the practice of hiding digital information by means
of various obfuscatory and steganographic techniques. The
application of said techniques facilitates message confidentiality
and sender/receiver identity authentication, and helps to ensure
the integrity and security of computer passwords, ATM card
information, digital signatures, DVD and HDDVD content, and
electronic commerce. Cryptography is also central to digital rights
management (DRM), a group of techniques for technologically
controlling the use of copyrighted material that is being widely
implemented and deployed at the behest of corporations that own and
create revenue from the hundreds of thousands of mini-transactions
that take place daily on programs like iTunes.
This book covers newly developed and novel Steganography techniques and algorithms. The book outlines techniques to provide security to a variety of applications using Steganography, with the goal of both hindering an adversary from decoding a hidden message, and also preventing an adversary from suspecting the existence of covert communications.

Information security has a major gap when cryptography is implemented. Cryptographic algorithms are well defined, key management schemes are well known, but the actual deployment is typically overlooked, ignored, or unknown. Cryptography is everywhere. Application and network architectures are typically well-documented but the cryptographic architecture is missing. This book provides a guide to discovering, documenting, and validating cryptographic architectures. Each chapter builds on the next to present information in a sequential process. This approach not only presents the material in a structured manner, it also serves as an ongoing reference guide for future use.
"This book is the encyclopedia of phishing. It provides views from
the payment, human, and technical perspectives. The material is
remarkably readable--each chapter is contributed by an expert on
that topic, but none require specialized background on the part of
the reader. The text will be useful for any professional who seeks
to understand phishing." Phishing attacks, or the practice of deceiving people into revealing sensitive data on a computer system, continue to mount. Here is the information you need to understand how phishing works, how to detect it, and how to prevent it. "Phishing and Countermeasures" begins with a technical introduction to the problem, setting forth the tools and techniques that phishers use, along with current security technology and countermeasures that are used to thwart them. Readers are not only introduced to current techniques of phishing, but also to emerging and future threats and the countermeasures that will be needed to stop them. The potential and limitations of all countermeasures presented in the text are explored in detail. In spite of the fact that phishing attacks constantly evolve, much of the material in this book will remain valid, given that the book covers the general principles as much as actual instances of phishing. While delving into a myriad of countermeasures and defense strategies, the authors also focus on the role of the user in preventing phishing attacks. The authors assert that countermeasures often fail not for technical reasons, but rather because users are unable or unwilling to use them. In response, the authors present a number ofcountermeasures that are simple for users to implement, or that can be activated without a user's direct participation. Moreover, the authors propose strategies for educating users. The text concludes with a discussion of how researchers and security professionals can ethically and legally perform phishing experiments to test the effectiveness of their defense strategies against the strength of current and future attacks. Each chapter of the book features an extensive bibliography to help readers explore individual topics in greater depth. With phishing becoming an ever-growing threat, the strategies presented in this text are vital for technical managers, engineers, and security professionals tasked with protecting users from unwittingly giving out sensitive data. It is also recommended as a textbook for students in computer science and informatics.

Move beyond the checklist and fully protect yourself from third-party cybersecurity risk Over the last decade, there have been hundreds of big-name organizations in every sector that have experienced a public breach due to a vendor. While the media tends to focus on high-profile breaches like those that hit Target in 2013 and Equifax in 2017, 2020 has ushered in a huge wave of cybersecurity attacks, a near 800% increase in cyberattack activity as millions of workers shifted to working remotely in the wake of a global pandemic. The 2020 SolarWinds supply-chain attack illustrates that lasting impact of this dramatic increase in cyberattacks. Using a technique known as Advanced Persistent Threat (APT), a sophisticated hacker leveraged APT to steal information from multiple organizations from Microsoft to the Department of Homeland Security not by attacking targets directly, but by attacking a trusted partner or vendor. In addition to exposing third-party risk vulnerabilities for other hackers to exploit, the damage from this one attack alone will continue for years, and there are no signs that cyber breaches are slowing. Cybersecurity and Third-Party Risk delivers proven, active, and predictive risk reduction strategies and tactics designed to keep you and your organization safe. Cybersecurity and IT expert and author Gregory Rasner shows you how to transform third-party risk from an exercise in checklist completion to a proactive and effective process of risk mitigation. Understand the basics of third-party risk management Conduct due diligence on third parties connected to your network Keep your data and sensitive information current and reliable Incorporate third-party data requirements for offshoring, fourth-party hosting, and data security arrangements into your vendor contracts Learn valuable lessons from devasting breaches suffered by other companies like Home Depot, GM, and Equifax The time to talk cybersecurity with your data partners is now. Cybersecurity and Third-Party Risk is a must-read resource for business leaders and security professionals looking for a practical roadmap to avoiding the massive reputational and financial losses that come with third-party security breaches.

Cryptography is a vital technology that underpins the security of information in computer networks. This book presents a comprehensive introduction to the role that cryptography plays in providing information security for everyday technologies such as the Internet, mobile phones, Wi-Fi networks, payment cards, Tor, and Bitcoin. This book is intended to be introductory, self-contained, and widely accessible. It is suitable as a first read on cryptography. Almost no prior knowledge of mathematics is required since the book deliberately avoids the details of the mathematics techniques underpinning cryptographic mechanisms. Instead our focus will be on what a normal user or practitioner of information security needs to know about cryptography in order to understand the design and use of everyday cryptographic applications. By focusing on the fundamental principles of modern cryptography rather than the technical details of current cryptographic technology, the main part this book is relatively timeless, and illustrates the application of these principles by considering a number of contemporary applications of cryptography. Following the revelations of former NSA contractor Edward Snowden, the book considers the wider societal impact of use of cryptography and strategies for addressing this. A reader of this book will not only be able to understand the everyday use of cryptography, but also be able to interpret future developments in this fascinating and crucially important area of technology.
Now that information has become the lifeblood of your organization, you must be especially vigilant about assuring it. The hacker, spy, or cyber-thief of today can breach any barrier if it remains unchanged long enough or has even the tiniest leak. In Information Assurance Architecture, Keith D. Willett draws on his over 25 years of technical, security, and business experience to provide a framework for organizations to align information assurance with the enterprise and their overall mission. The Tools to Protect Your Secrets from Exposure This work provides the security industry with the know-how to create a formal information assurance architecture that complements an enterprise architecture, systems engineering, and the enterprise life cycle management (ELCM). Information Assurance Architecture consists of a framework, a process, and many supporting tools, templates and methodologies. The framework provides a reference model for the consideration of security in many contexts and from various perspectives; the process provides direction on how to apply that framework. Mr. Willett teaches readers how to identify and use the right tools for the right job. Furthermore, he demonstrates a disciplined approach in thinking about, planning, implementing and managing security, emphasizing that solid solutions can be made impenetrable when they are seamlessly integrated with the whole of an enterprise. Understand the Enterprise Context This book covers many information assurance subjects, including disaster recovery and firewalls. The objective is to present security services and security mechanisms in the context of information assurance architecture, and in an enterprise context of managing business risk. Anyone who utilizes the concepts taught in these pages will find them to be a valuable weapon in the arsenal of information protection.
The Most Progressive and Complete Guide to DDO-Based Ciphers Developers have long recognized that ciphers based on Permutation Networks (PNs) and Controlled Substitution-Permutation Networks (CSPNs) allow for the implementation of a variety of Data Driven Operations (DDOs). These DDOs can provide fast encryption without incurring excessive hardware costs in modern telecommunication networks. However, until now, with a few exceptions, most DDO-based ciphers have been poorly represented in available literature and have continued to remain known to only a small number of encryption experts. In Data-Driven Block Ciphers for Fast Telecommunication Systems, Nikolai Moldovyan and Alexander Moldovyan, major innovators and holders of several dozen international patents in encryption technology, provide the background and detail the applications needed to investigate new properties of PNs especially relevant to the improvement of modern wireless systems.Furthermore, they propose a universal architecture involving controlled bit permutation instruction that will permit the performance of both data-driven permutations and an arbitrary prescribed fixed permutation in a single cycle. Immediately improved efficiency for current and future fast telecommunication systems and mobile networksBecause of its simplicity and efficient use of current hardware, the embedding of this architecture is a highly attractive option for CPU manufacturers.By detailing all the relevant information into a single volume for the first time, the authors of this book make that option more feasible than ever before.
Computer Forensics: Evidence Collection and Management examines cyber-crime, E-commerce, and Internet activities that could be used to exploit the Internet, computers, and electronic devices. The book focuses on the numerous vulnerabilities and threats that are inherent on the Internet and networking environments and presents techniques and suggestions for corporate security personnel, investigators, and forensic examiners to successfully identify, retrieve, and protect valuable forensic evidence for litigation and prosecution. The book is divided into two major parts for easy reference. The first part explores various crimes, laws, policies, forensic tools, and the information needed to understand the underlying concepts of computer forensic investigations. The second part presents information relating to crime scene investigations and management, disk and file structure, laboratory construction and functions, and legal testimony. Separate chapters focus on investigations involving computer systems, e-mail, and wireless devices. Presenting information patterned after technical, legal, and managerial classes held by computer forensic professionals from Cyber Crime Summits held at Kennesaw State University in 2005 and 2006, this book is an invaluable resource for those who want to be both efficient and effective when conducting an investigation.
The modern dependence upon information technology and the corresponding information security regulations and requirements force companies to evaluate the security of their core business processes, mission critical data, and supporting IT environment. Combine this with a slowdown in IT spending resulting in justifications of every purchase, and security professionals are forced to scramble to find comprehensive and effective ways to assess their environment in order to discover and prioritize vulnerabilities, and to develop cost-effective solutions that show benefit to the business. A Practical Guide to Security Assessments is a process-focused approach that presents a structured methodology for conducting assessments. The key element of the methodology is an understanding of business goals and processes, and how security measures are aligned with business risks. The guide also emphasizes that resulting security recommendations should be cost-effective and commensurate with the security risk. The methodology described serves as a foundation for building and maintaining an information security program. In addition to the methodology, the book includes an Appendix that contains questionnaires that can be modified and used to conduct security assessments. This guide is for security professionals who can immediately apply the methodology on the job, and also benefits management who can use the methodology to better understand information security and identify areas for improvement.
An organization's employees are often more intimate with its computer system than anyone else. Many also have access to sensitive information regarding the company and its customers. This makes employees prime candidates for sabotaging a system if they become disgruntled or for selling privileged information if they become greedy. Insider Computer Fraud: An In-depth Framework for Detecting and Defending against Insider IT Attacks presents the methods, safeguards, and techniques that help protect an organization from insider computer fraud. Drawing from the author's vast experience assessing the adequacy of IT security for the banking and securities industries, the book presents a practical framework for identifying, measuring, monitoring, and controlling the risks associated with insider threats. It not only provides an analysis of application or system-related risks, it demonstrates the interrelationships that exist between an application and the IT infrastructure components it uses to transmit, process, and store sensitive data. The author also examines the symbiotic relationship between the risks, controls, threats, and action plans that should be deployed to enhance the overall information security governance processes. Increasing the awareness and understanding necessary to effectively manage the risks and controls associated with an insider threat, this book is an invaluable resource for those interested in attaining sound and best practices over the risk management process. |
