Overview of this book

Identifying and classifying information inside a company is one of the most important prerequisites for securing the sensitive information of various business units. Windows Server 2012 Dynamic Access Control helps you not only to classify information, but it also gives you the opportunity and the functionality to provide a safe-net policy across your file servers, showing you some helpful ways of auditing and access denied assistance to improve usability. Understanding the architecture, the design, and implementing the solution, to troubleshooting will be covered in a practical and easy-to-read manner. This book is packed with project-based examples with plenty of information about the architecture, functionality, and extensions of Dynamic Access Control to help you excel in real-life projects. The book guides you through all the stages of a successful implementation of Dynamic Access Control. Microsoft Windows Server 2012 Dynamic Access Control will teach you everything you need to know to create your own projects, and is an essential resource for reviewing or extending already existing implementations. The book initially takes you through the task of understanding all of the functionality and extensions with ideas and overviews to help guide you in the decision process. The whole architecture will be explained in the main building blocks of Dynamic Access control. You will have a strong foundation and understanding of the claims model and Kerberos. Classifying information, the hardest part of the prerequisites to fulfil, is also covered in depth. You will also spend time understanding conditional expressions, and the method used to deploy them across your file server infrastructure. A special chapter is included for handling the data quality and the integration in other systems and strategies. Last, but not least, to get your solution up and running you will learn how to troubleshoot a Dynamic Access Control solution.

Defining expression-based Access policies


After classifying the information, we will define the access rights that the users will have to these file resources. This can be done by configuring an expression-based access on the classified files. What this means is that we will use conditional expressions (conditional permissions) to secure the access to our information. This concept is not new; Microsoft already allows these entries with Windows 7. Conditional expressions are Boolean or logical expressions, and provide either a TRUE or FALSE result. Remember, in the prereleases of Windows Server, we used groups and group nesting to give access to resources. Just to give you a smart example of the syntax, consider the following diagram:

In the example, we want to give access to the file resources if the user has set the country attribute to CH (Switzerland) and the user department to HR or Legal:

  • The Left-hand-side (LHS) Conditional Expression should be @User.Country=="CH", which means that the...
