Book Synopsis Zero Trust Networks by : Evan Gilman
Download or read book Zero Trust Networks written by Evan Gilman and published by "O'Reilly Media, Inc.". This book was released on 2017-06-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it. The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. Understand how perimeter-based defenses have evolved to become the broken model we use today Explore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty) Get example configuration for open source tools that you can use to build a zero trust network Learn how to migrate from a perimeter-based network to a zero trust network in production

Available in PDF, EPUB and Kindle. Book excerpt: This exciting book will explore how Blockchain (BC) technology has the potential to overcome challenges in the current cyber-physical system (CPS) environment. BC is a timestamp ledger of blocks that is used for storing and sharing data in a distributed manner. BC has attracted attention from practitioners and academics in different disciplines, including law, finance, and computer science, due to its use of distributed structure, immutability and security and privacy. However, applying blockchain in a cyber-physical system (CPS) is not straightforward and involves challenges, including lack of scalability, resource consumption, and delay. This book will provide a comprehensive study on blockchain for CPS. CPS and the existing solutions in CPS and will outline the limitations are presented. The key features of blockchain and its salient features which makes it an attractive solution for CPS are discussed. The fundamental challenges in adopting blockchain for CPS including scalability, delay, and resource consumption are presented and described. Blockchain applications in smart grids, smart vehicles, supply chain; and IoT Data marketplaces are explored. The future research directions to further improve blockchain performance in CPS is also provided.

Book Synopsis Social Networks and Trust by : Vincent Buskens
Download or read book Social Networks and Trust written by Vincent Buskens and published by Springer Science & Business Media. This book was released on 2005-12-27 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social Networks and Trust discusses two possible explanations for the emergence of trust via social networks. If network members can sanction untrustworthiness of actors, these actors may refrain from acting in an untrustworthy manner. Moreover, if actors are informed regularly about trustworthy behavior of others, trust will grow among these actors. A unique combination of formal model building and empirical methodology is used to derive and test hypotheses about the effects of networks on trust. The models combine elements from game theory, which is mainly used in economics, and social network analysis, which is mainly used in sociology. The hypotheses are tested (1) by analyzing contracts in information technology transactions from a survey on small and medium-sized enterprises and (2) by studying judgments of subjects in a vignette experiment related to hypothetical transactions with a used-car dealer.

Book Synopsis Migration-Trust Networks by : Nadia Yamel Flores-Yeffal
Download or read book Migration-Trust Networks written by Nadia Yamel Flores-Yeffal and published by Texas A&M University Press. This book was released on 2013-04-26 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an important new application of sociological theories, Nadia Y. Flores-Yeffal offers fresh insights into the ways in which social networks function among immigrants who arrive in the United States from Mexico without legal documentation. She asks and examines important questions about the commonalities and differences in networks for this group compared with other immigrants, and she identifies “trust” as a major component of networking among those who have little if any legal protection. Revealing the complexities behind social networks of international migration, Migration-Trust Networks: Social Cohesion in Mexican US-Bound Emigration provides an empirical and theoretical analysis of how social networks of international migration operate in the transnational context. Further, the book clarifies how networking creates chain migration effects observable throughout history. Flores-Yeffal’s study extends existing social network theories, providing a more detailed description of the social micro- and macrodynamics underlying the development and expansion of social networks used by undocumented Mexicans to migrate and integrate within the United States, with trust relationships as the basis of those networks. In addition, it incorporates a transnational approach in which the migrant’s place of origin, whether rural or urban, becomes an important variable. Migration-Trust Networks encapsulates the new realities of undocumented migration from Latin America and contributes to the academic discourse on international migration, advancing the study of social networks of migration and of social networks in general.

Book Synopsis Trust-based Recommendations in Multi-layer Networks by : Claudia Heß
Download or read book Trust-based Recommendations in Multi-layer Networks written by Claudia Heß and published by IOS Press. This book was released on 2008 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The huge interest in social networking applications – Friendster.com, for example, has more than 40 million users – led to a considerable research interest in using this data for generating recommendations. Especially recommendation techniques that analyze trust networks were found to provide very accurate and highly personalized results. The main contribution of this thesis is to extend the approach to trust-based recommendations, which up to now have been made for unlinked items such as products or movies, to linked resources, in particular documents. Therefore, a second type of network, namely a document reference network, is considered apart from the trust network. This is, for example, the citation network of scientific publications or the hyperlink graph of webpages. Recommendations for documents are typically made by reference-based visibility measures which consider a document to be the more important, the more often it is referenced by important documents. These two networks, as well as further networks such as organization networks, are integrated in a multi-layer network. This architecture allows for combining classical measures for the visibility of a document with trust-based recommendations, giving trust-enhanced visibility measures. Moreover, an approximation approach is introduced which considers the uncertainty induced by duplicate documents. These measures are evaluated in simulation studies. The trust-based recommender system for scientific publications SPRec implements a two-layer architecture and provides personalized recommendations via a web interface.
Book Synopsis Security and Trust in Online Social Networks by : Barbara Carminati
Download or read book Security and Trust in Online Social Networks written by Barbara Carminati and published by Springer Nature. This book was released on 2022-05-31 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enormous success and diffusion that online social networks (OSNs) are encountering nowadays is vastly apparent. Users' social interactions now occur using online social media as communication channels; personal information and activities are easily exchanged both for recreational and business purposes in order to obtain social or economic advantages. In this scenario, OSNs are considered critical applications with respect to the security of users and their resources, for their characteristics alone: the large amount of personal information they manage, big economic upturn connected to their commercial use, strict interconnection among users and resources characterizing them, as well as user attitude to easily share private data and activities with strangers. In this book, we discuss three main research topics connected to security in online social networks: (i) trust management, because trust can be intended as a measure of the perception of security (in terms of risks/benefits) that users in an OSN have with respect to other (unknown/little-known) parties; (ii) controlled information sharing, because in OSNs, where personal information is not only connected to user profiles, but spans across users' social activities and interactions, users must be provided with the possibility to directly control information flows; and (iii) identity management, because OSNs are subjected more and more to malicious attacks that, with respect to traditional ones, have the advantage of being more effective by leveraging the social network as a new medium for reaching victims. For each of these research topics, in this book we provide both theoretical concepts as well as an overview of the main solutions that commercial/non-commercial actors have proposed over the years. We also discuss some of the most promising research directions in these fields.
