A Guide to the National Initiative for Cybersecurity Education: A Guide To The National Initiative For Cybersecurity Education (nice) Framework (2. 0) (Security, Audit and Leadership Series)
by Dan Shoemaker Anne Kohnke Ken SiglerA Guide to the National Initiative for Cybersecurity Education (NICE) Cybersecurity Workforce Framework (2.0) presents a comprehensive discussion of the tasks, knowledge, skill, and ability (KSA) requirements of the NICE Cybersecurity Workforce Framework 2.0. It discusses in detail the relationship between the NICE framework and the NIST’s cybersecurity framework (CSF), showing how the NICE model specifies what the particular specialty areas of the workforce should be doing in order to ensure that the CSF’s identification, protection, defense, response, or recovery functions are being carried out properly. The authors construct a detailed picture of the proper organization and conduct of a strategic infrastructure security operation, describing how these two frameworks provide an explicit definition of the field of cybersecurity. The book is unique in that it is based on well-accepted standard recommendations rather than presumed expertise. It is the first book to align with and explain the requirements of a national-level initiative to standardize the study of information security. Moreover, it contains knowledge elements that represent the first fully validated and authoritative body of knowledge (BOK) in cybersecurity. The book is divided into two parts: The first part is comprised of three chapters that give you a comprehensive understanding of the structure and intent of the NICE model, its various elements, and their detailed contents. The second part contains seven chapters that introduce you to each knowledge area individually. Together, these parts help you build a comprehensive understanding of how to organize and execute a cybersecurity workforce definition using standard best practice.

Project Management in Extreme Situations: Lessons from Polar Expeditions, Military and Rescue Operations, and Wilderness Exploration (Leading Works from the French School of Management)
by Monique Aubry Pascal LievreThe growing complexity of projects today, as well as the uncertainty inherent in innovative projects, is making obsolete traditional project management practices and procedures, which are based on the notion that much about a project is known at its start. The current high level of change and complexity confronting organizational leaders and managers requires a new approach to projects so they can be managed flexibly to embrace and exploit change. What once used to be considered extreme uncertainty is now the norm, and managing planned projects is being replaced by managing projects as they evolve. <P><P>Successfully managing projects in extreme situations, such as polar and military expeditions, shows how to manage successfully projects in today’s turbulent environment. Executed under the harshest and most unpredictable conditions, these projects are great sources for learning about how to manage unexpected and unforeseen situations as they occur. This book presents multiple case studies of managing extreme events as they happened during polar, mountain climbing, military, and rescue expeditions. <P><P>A boat accident in the Artic is a lesson on how an effective project manager must be ambidextrous: on one hand able to follow plans and on the other hand able to abandon those plans when disaster strikes and improvise new ones in response. Polar expeditions also illustrate how a team can use "weak links" to go beyond its usual information network to acquire strategic information. Fire and rescues operations illustrate how one team member’s knowledge can be transferred to the entire team. Military operations provide case material on how teams coordinate and make use of both individual and collective competencies. <P><P>This groundbreaking work pushes the definitions of a project and project management to reveal new insight that benefits researchers, academics, and the practitioners managing projects in today’s challenging and uncertain times.
Interconnections for Computer Communications and Packet Networks
by Roberto Rojas-CessaThis book introduces different interconnection networks applied to different systems. Interconnection networks are used to communicate processing units in a multi-processor system, routers in communication networks, and servers in data centers. Queuing techniques are applied to interconnection networks to support a higher utilization of resources. There are different queuing strategies, and these determine not only the performance of the interconnection network, but also the set of requirements to make them work effectively and their cost. Routing algorithms are used to find routes to destinations and directions in what information travels. Additional properties, such as avoiding deadlocks and congestion, are sought. Effective routing algorithms need to be paired up with these networks. The book will introduce the most relevant interconnection networks, queuing strategies, and routing algorithm. It discusses their properties and how these leverage the performance of the whole interconnection system. In addition, the book covers additional topics for memory management and congestion avoidance, used to extract higher performance from the interconnection network.
Understanding Interaction: Volume 1: Evolution, Technology, Language and Culture
by Bert BongersUnderstanding Interaction explores the interaction between people and technology in the broader context of the relations between the human-made and the natural environments. It is not just about digital technologies – our computers, smartphones, the Internet – but all our technologies, such as mechanical, electrical, and electronic. Our ancestors started creating mechanical tools and shaping their environments millions of years ago, developing cultures and languages, which in turn influenced our evolution. Volume 1 looks into this deep history, starting from the tool-creating period (the longest and most influential on our physical and mental capacities) to the settlement period (agriculture, domestication, villages and cities, written language), the industrial period (science, engineering, reformation, and renaissance), and finally the communication period (mass media, digital technologies, and global networks). Volume 2 looks into humans in interaction – our physiology, anatomy, neurology, psychology, how we experience and influence the world, and how we (think we) think. From this transdisciplinary understanding, design approaches and frameworks are presented to potentially guide future developments and innovations. The aim of the book is to be a guide and inspiration for designers, artists, engineers, psychologists, media producers, social scientists, etc., and, as such, be useful for both novices and more experienced practitioners.

Theory of User Engineering
by Masaaki KurosuThis book outlines the new concept of user engineering and covers the diversity of users, along with the business process that includes the design and the user’s experience processes. Although the concept of user experience (UX) has become popular, the definition and the methodology are still ambiguous. User engineering is similar to the user-centered design, but differs in that its scope is not limited to the design process but concerns the whole manufacturing process and the whole usage process, i.e., the whole lifecycle of an artifact. User’s perspective is strongly emphasized in this book, hence, its stance is far from that of the marketing approach that usually fails to notice the life and experiences of users after the purchase of an artifact as consumers. Theory of User Engineering differentiates between the quality in design and the quality in use, and the objective quality characteristics and the subjective quality characteristics. In addition to the user research using ethnographic methods, the author introduces a new approach based on the artifact evolution theory that can be adopted in the planning stage.

Introduction to Visual Computing: Core Concepts in Computer Vision, Graphics, and Image Processing
by Aditi Majumder M. GopiIntroduction to Visual Computing: Core Concepts in Computer Vision, Graphics, and Image Processing covers the fundamental concepts of visual computing. Whereas past books have treated these concepts within the context of specific fields such as computer graphics, computer vision or image processing, this book offers a unified view of these core concepts, thereby providing a unified treatment of computational and mathematical methods for creating, capturing, analyzing and manipulating visual data (e.g. 2D images, 3D models). Fundamentals covered in the book include convolution, Fourier transform, filters, geometric transformations, epipolar geometry, 3D reconstruction, color and the image synthesis pipeline. The book is organized in four parts. The first part provides an exposure to different kinds of visual data (e.g. 2D images, videos and 3D geometry) and the core mathematical techniques that are required for their processing (e.g. interpolation and linear regression.) The second part of the book on Image Based Visual Computing deals with several fundamental techniques to process 2D images (e.g. convolution, spectral analysis and feature detection) and corresponds to the low level retinal image processing that happens in the eye in the human visual system pathway. The next part of the book on Geometric Visual Computing deals with the fundamental techniques used to combine the geometric information from multiple eyes creating a 3D interpretation of the object and world around us (e.g. transformations, projective and epipolar geometry, and 3D reconstruction). This corresponds to the higher level processing that happens in the brain combining information from both the eyes thereby helping us to navigate through the 3D world around us. The last two parts of the book cover Radiometric Visual Computing and Visual Content Synthesis. These parts focus on the fundamental techniques for processing information arising from the interaction of light with objects around us, as well as the fundamentals of creating virtual computer generated worlds that mimic all the processing presented in the prior sections. The book is written for a 16 week long semester course and can be used for both undergraduate and graduate teaching, as well as a reference for professionals.

Outlining proper operating procedures, planning, implementation, and drills, it demonstrates how proper planning and effective management systems in place prior to a crisis can mean the difference between life and death. The book helps organizations establish best practices in crisis management to ensure safety and security of personnel, assets, and properties overseas, even in potentially volatile environments.
Information Security Policies, Procedures, and Standards: A Practitioner's Reference
by Douglas J. LandollInformation Security Policies, Procedures, and Standards: A Practitioner's Reference gives you a blueprint on how to develop effective information security policies and procedures. It uses standards such as NIST 800-53, ISO 27001, and COBIT, and regulations such as HIPAA and PCI DSS as the foundation for the content. Highlighting key terminology, policy development concepts and methods, and suggested document structures, it includes examples, checklists, sample policies and procedures, guidelines, and a synopsis of the applicable standards. The author explains how and why procedures are developed and implemented rather than simply provide information and examples. This is an important distinction because no two organizations are exactly alike; therefore, no two sets of policies and procedures are going to be exactly alike. This approach provides the foundation and understanding you need to write effective policies, procedures, and standards clearly and concisely. Developing policies and procedures may seem to be an overwhelming task. However, by relying on the material presented in this book, adopting the policy development techniques, and examining the examples, the task will not seem so daunting. You can use the discussion material to help sell the concepts, which may be the most difficult aspect of the process. Once you have completed a policy or two, you will have the courage to take on even more tasks. Additionally, the skills you acquire will assist you in other areas of your professional and private life, such as expressing an idea clearly and concisely or creating a project plan.

Image Content Retargeting: Maintaining Color, Tone, and Spatial Consistency
by Alessandro Artusi Francesco Banterle Tunç Ozan Aydın Daniele Panozzo Olga Sorkine-HornungIn recent years visual devices have proliferated, from the massive high-resolution, high-contrast screens to the tiny ones on mobile phones, with their limited dynamic range and color gamut. The wide variety of screens on which content may be viewed creates a challenge for developers. Adapting visual content for optimized viewing on all devices is called retargeting. This is the first book to provide a holistic view of the subject, thoroughly reviewing and analyzing the many techniques that have been developed for retargeting along dimensions such as color gamut, dynamic range, and spatial resolution.
