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

Network access control (NAC) is how you manage network security when your employees, partners, and guests need to access your network using laptops and mobile devices. Network Access Control For Dummies is where you learn how NAC works, how to implement a program, and how to take real-world challenges in stride. You’ll learn how to deploy and maintain NAC in your environment, identify and apply NAC standards, and extend NAC for greater network security. Along the way you’ll become familiar with what NAC is (and what it isn’t) as well as the key business drivers for deploying NAC. Learn the steps of assessing, evaluating, remediating, enforcing, and monitoring your program Understand the essential functions of Authentication, Authorization, and Accounting Decide on the best NAC approach for your organization and which NAC policies are appropriate Discover how to set policies that are enforceable and reasonable enough to be followed, yet still effective Become familiar with the architectures and standards essential to NAC Involve and motivate everyone in the organization whose support is critical to a successful implementation Network Access Control For Dummies shows you the steps for planning your implementation, who should be involved, where enforcement should occur, and much more. When you flip the switch, you’ll know what to expect.

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.

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.

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.

This book constitutes the thoroughly refereed post-conference proceedings of the International Conference on Trusted Systems, INTRUST 2011, held in Beijing, China, in November 2011. The 21 revised full papers were carefully reviewed and selected from 34 submissions for inclusion in the book. Except these contributed papers the program of INTRUST also consisted of a workshop titled Asian Lounge on Trust, Security and Privacy consisting of six keynote speeches. The papers are organized in topical sections on trusted services, mobile trusted systems, security analysis, cryptographic aspects, trusted networks, implementation, and direct anonymous attestation.
