A Guide To Claims Based Identity And Access Control

A Guide to Claims-based Identity and Access Control

A Guide to Claims-Based Identity and Access Control, Version 2

As an application designer or developer, imagine a world where you don?t have to worry about authentication. Imagine instead that all requests to your application already include the information you need to make access control decisions and to personalize the application for the user. In this world, your applications can trust another system component to securely provide user information, such as the user?s name or e-mail address, a manager?s e-mail address, or even a purchasing authorization limit. The user?s information always arrives in the same simple format, regardless of the authentication mechanism, whether it?s Microsoft Windows integrated authentication, forms-based authentication in a Web browser, an X.509 client certificate, Windows Azure Access Control Service, or something more exotic. Even if someone in charge of your company?s security policy changes how users authenticate, you still get the information, and it?s always in the same format. This is the utopia of claims-based identity that A Guide to Claims-Based Identity and Access Control describes. As you?ll see, claims provide an innovative approach for building applications that authenticate and authorize users. This book gives you enough information to evaluate claims-based identity as a possible option when you?re planning a new application or making changes to an existing one. It is intended for any architect, developer, or information technology (IT) professional who designs, builds, or operates web applications, web services, or SharePoint applications that require identity information about their users.

Authorization and Access Control

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.
