We depend on information and information technology (IT) to make many of our day-to-day tasks easier and more convenient. Computers play key roles in transportation, health care, banking, and energy. Businesses use IT for payroll and accounting, inventory and sales, and research and development. Modern military forces use weapons that are increasingly coordinated through computer-based networks. Cybersecurity is vital to protecting all of these functions. Cyberspace is vulnerable to a broad spectrum of hackers, criminals, terrorists, and state actors. Working in cyberspace, these malevolent actors can steal money, intellectual property, or classified information; impersonate law-abiding parties for their own purposes; damage important data; or deny the availability of normally accessible services. Cybersecurity issues arise because of three factors taken together - the presence of malevolent actors in cyberspace, societal reliance on IT for many important functions, and the presence of vulnerabilities in IT systems. What steps can policy makers take to protect our government, businesses, and the public from those would take advantage of system vulnerabilities? At the Nexus of Cybersecurity and Public Policy offers a wealth of information on practical measures, technical and nontechnical challenges, and potential policy responses. According to this report, cybersecurity is a never-ending battle; threats will evolve as adversaries adopt new tools and techniques to compromise security. Cybersecurity is therefore an ongoing process that needs to evolve as new threats are identified. At the Nexus of Cybersecurity and Public Policy is a call for action to make cybersecurity a public safety priority. For a number of years, the cybersecurity issue has received increasing public attention; however, most policy focus has been on the short-term costs of improving systems. In its explanation of the fundamentals of cybersecurity and the discussion of potential policy responses, this book will be a resource for policy makers, cybersecurity and IT professionals, and anyone who wants to understand threats to cyberspace.

Computer and Communication Networks, Second Edition first establishes a solid foundation in basic networking concepts, TCP/IP schemes, wireless networking, Internet applications, and network security. Next, Mir delves into the mathematical analysis of networks, as well as advanced networking protocols. This fully-updated text thoroughly explains the modern technologies of networking and communications among computers, servers, routers, and other smart communication devices, helping readers design cost-effective networks that meet emerging requirements. Offering uniquely balanced coverage of all key basic and advanced topics, it teaches through extensive, up-to-date case studies, 400 examples and exercises, and 250+ illustrative figures. Nader F. Mir provides the practical, scenario-based information many networking books lack, and offers a uniquely effective blend of theory and implementation. Drawing on extensive experience in the field, he introduces a wide spectrum of contemporary applications, and covers several key topics that competitive texts skim past or ignore completely, such as Software-Defined Networking (SDN) and Information-Centric Networking.

The rush to the Information Superhighway and the transition to an Information Age have enormous political, ethical, and religious consequences. The essays collected here develop both interdisciplinary and international perspectives on privacy, critical thinking and literacy, democratization, gender, religion, and the very nature of the revolution promised in cyberspace. These essays are essential reading for anyone who wants to better understand and reflect upon these events and issues.

This is a uniquely friendly and easy-to-understand treatment of the complex theories and findings that surround CMC. Communication is often complicated, and computerization makes it stranger still, yet the authors have deftly demystified both the miraculous and the mundane of computer-mediated interaction.

In 1968 the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense began implementation of a computer communication network which permits the interconnection of heter ogeneous computers at geographically distributed centres through out the United States. This network has come to be known as the ARPANET and has grown from the initial four node configuration in 1969 to almost forty nodes (including satellite nodes in Hawaii, Norway, and London) in late 1973. The major goal of ARPANET is to achieve resource sharing among the network users. The resources to be shared include not only programs, but also unique facilities such as the powerful ILLIAC IV computer and large global weather data bases that are economically feasible when widely shared. The ARPANEr employs a distributed store-and-forward packet switching approach that is much better suited for computer communications networks than the more conventional circuit-switch ing approach. Reasons favouring packet switching include lower cost, higher capacity, greater reliability and minimal delay. All of these factors are discussed in these Proceedings.

Computers and the Internet gave rise to the emergence of computer-mediated communication (CMC). The Influence of Computers, the Internet and Computer-Mediated Communication on Everyday English focuses on the use of English in connection with computers and the Internet and on its influences on everyday English by analysing the dispersal of new meanings of words, neologisms, features of CMC and new metaphors. The intention is to show the computer- and Internet-related impact on the English language from several perspectives and to take several ways into consideration in which the Internet and CMC are changing language use and to evaluate this influence -- at least as far as this is possible.
