Access control, security and trust are among the greatest risks—compliance and otherwise—facing corporations today. Controlling access to protected objects is central to any security program, and the foundation of Access Control, Security, and Trust: A Logical Approach is straightforward: Reference monitors are the means to protect objects of value in systems.
Access Control, Security, and Trust: A Logical Approach is intended to serve the needs of computer engineers and computer scientists who are responsible for specifying, designing, implementing, building, and verifying or certifying secure computer and information systems. However, beginners to the study of access security will be enlightened by the education presented, as the authors remain cognizant throughout the book of the reader’s need to understand the basic concepts of authentication and authorization. The book provides answers to the following dilemmas:
The publication aims to fill a gap left by many books on computer and network security. The book lays out algorithm logic, but does not require a highly mathematical intellect to understand its contents. The publication’s methodical focus on access control and reference monitors introduces a language for describing access-control scenarios, inference rules and resulting formulas. The authors explain the concepts in elementary, easy-to-understand language and leave in-depth understanding of the mathematical concepts optional for later reading.
Access Control, Security, and Trust: A Logical Approach is divided into four parts: Preliminaries, Distributed Access Control, Isolation and Sharing, and Access Policies. Part I explains the language and basics of access control, reasoning and reference rules. Building on these concepts of security mechanisms, this part also differentiates among and describes security policy types. Part II explores distributed access control in network environments, digital authentication, and delegation concepts and protocols. Part III ties the logical lessons of the first two sections into the core of cybersecurity: hardware security. Part IV expands on the security policies discussed in part I and introduces a richer notion of confidentiality and integrity levels, models and policies based on principles, objects and roles.
The unique strength of the 326-page book is its plethora of tables and exercises, converting its mathematical logic into real-world, nonmathematical language and visuals. Chapter summaries recap the line-by-line mathematical formulas in unambiguous statements.
