Access Control Security And Trust

Developed from the authors’ courses at Syracuse University and the U.S. Air Force Research Laboratory, Access Control, Security, and Trust: A Logical Approach equips readers with an access control logic they can use to specify and verify their security designs. Throughout the text, the authors use a single access control logic based on a simple propositional modal logic. The first part of the book presents the syntax and semantics of access control logic, basic access control concepts, and an introduction to confidentiality and integrity policies. The second section covers access control in networks, delegation, protocols, and the use of cryptography. In the third section, the authors focus on hardware and virtual machines. The final part discusses confidentiality, integrity, and role-based access control. Taking a logical, rigorous approach to access control, this book shows how logic is a useful tool for analyzing security designs and spelling out the conditions upon which access control decisions depend. It is designed for computer engineers and computer scientists who are responsible for designing, implementing, and verifying secure computer and information systems.

This essential resource for professionals and advanced students in security programming and system design introduces the foundations of programming systems security and the theory behind access control models, and addresses emerging access control mechanisms.

Using propositional modal logic to explain access control principles, this workprovides the mathematical means to comprehend, analyze, create and verify the policies and control mechanisms used to protect resources. It starts with a preliminary introduction and then covers distributed access control, resources and sharing, and security monitors, the latter of which serves as a bridge to classical security models. While structured as a text for advanced undergraduates and graduate students, the book also meets the reference needs of those computer engineers, computer scientists, and information technologists responsible for designing, implementing, and verifying computer and information systems.

This open access book constitutes the proceedings of the 8th International Conference on Principles of Security and Trust, POST 2019, which took place in Prague, Czech Republic, in April 2019, held as part of the European Joint Conference on Theory and Practice of Software, ETAPS 2019. The 10 papers presented in this volume were carefully reviewed and selected from 27 submissions. They deal with theoretical and foundational aspects of security and trust, including on new theoretical results, practical applications of existing foundational ideas, and innovative approaches stimulated by pressing practical problems.

This book focuses on various authorization and access control techniques, threats and attack modeling, including an overview of the Open Authorization 2.0 (OAuth 2.0) framework along with user-managed access (UMA) and security analysis. Important key concepts are discussed regarding login credentials with restricted access to third parties with a primary account as a resource server. A detailed protocol overview and authorization process, along with security analysis of OAuth 2.0, are also discussed in the book. Case studies of websites with vulnerability issues are included. FEATURES Provides an overview of the security challenges of IoT and mitigation techniques with a focus on authorization and access control mechanisms Discusses a behavioral analysis of threats and attacks using UML base modeling Covers the use of the OAuth 2.0 Protocol and UMA for connecting web applications Includes role-based access control (RBAC), discretionary access control (DAC), mandatory access control (MAC) and permission-based access control (PBAC) Explores how to provide access to third-party web applications through a resource server by use of a secured and reliable OAuth 2.0 framework This book is for researchers and professionals who are engaged in IT security, auditing and computer engineering.

This book constitutes the proceedings of the 17th International Workshop on Security and Trust Management, STM 2021, co-located with the 26th European Symposium on Research in Computer Security, ESORICS 2021. The conference was planned to take place in Darmstadt, Germany. It was held online on October 8, 2021, due to the COVID-19 pandemic. The 10 papers presented in this volume were carefully reviewed and selected from 26 submissions. They were organized in topical sections on applied cryptography; privacy; formal methods for security and trust; and systems security.

The vision of ubiquitous computing and ambient intelligence describes a world of technology which is present anywhere, anytime in the form of smart, sensible devices that communicate with each other and provide personalized services. However, open interconnected systems are much more vulnerable to attacks and unauthorized data access. In the context of this threat, this book provides a comprehensive guide to security and privacy and trust in data management.

This book constitutes the thoroughly refereed post-conference proceedings of the 7th International Workshop on Security and Trust Management, STM 2011, held in Copenhagen, Denmark, in June 2011 - co-located with IFIPTM 2011, the 5th IFIP International Conference on Trust Management. The 12 revised full papers presented together with 4 invited papers were carefully reviewed and selected from 33 submissions. Focusing on high-quality original unpublished research, case studies, and implementation experiences, STM 2011 features submissions from academia, industry, and government presenting novel research on all theoretical and practical aspects of security and trust in information and communication technologies.
