Download or read book Assessing Cyber Security written by Maarten Gehem and published by The Hague Centre for Strategic Studies. This book was released on 2015-04-16 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the years, a plethora of reports has emerged that assess the causes, dynamics, and effects of cyber threats. This proliferation of reports is an important sign of the increasing prominence of cyber attacks for organizations, both public and private, and citizens all over the world. In addition, cyber attacks are drawing more and more attention in the media. Such efforts can help to better awareness and understanding of cyber threats and pave the way to improved prevention, mitigation, and resilience. This report aims to help in this task by assessing what we know about cyber security threats based on a review of 70 studies published by public authorities, companies, and research organizations from about 15 countries over the last few years. It answers the following questions: what do we know about the number, origin, and impact of cyber attacks? What are the current and emerging cyber security trends? And how well are we prepared to face these threats?

This book was released on 2016-06-29 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human Computer Interaction (HCI) is easy to define yet difficult to predict. Encompassing the management, study, planning, and design of the ways in which users interact with computers, this field has evolved from using punch cards to force touch in a matter of decades. What was once considered science fiction is now ubiquitous. The future of HCI is mercurial, yet predictions point to the effortless use of high-functioning services. The Handbook of Research on Human-Computer Interfaces, Developments, and Applications is primarily concerned with emerging research regarding gesture interaction, augmented reality, and assistive technologies and their place within HCI. From gaming to rehabilitation systems, these new technologies share the need to interface with humans, and as computers become thoroughly integrated into everyday life, so does the necessity of HCI research. This handbook of research benefits the research needs of programmers, developers, students and educators in computer science, and researchers.
