MICROSOFT DYNAMICS AX 2012 R3 SECURITY

Chapter 2. Security Coding

In this chapter, we are going to illustrate X++ security coding and how to use Code Access Security (CAS). We will also talk about the new compiler enhancement in Microsoft Dynamics AX 2012 R3 and how it affects the compiling process within the system and the debugging tools. Finally, we will introduce the new features in Microsoft Dynamics AX 2012 R3.

The topics covered in this chapter are as follows:

  • The fundamentals of security coding using X++
  • Using Code Access Security
  • Security debugging
  • Security for the Display and Edit methods
  • The Table Permissions Framework

The fundamentals of security coding using X++

In this chapter, we will cover the trustworthy computing features of Microsoft Dynamics AX 2012 and how they affect security coding.

X++ is an object-oriented language like any other programming language, for example, C++. It allows developers to design data types, tables, queries, forms, menus, and reports. It also allows access to the application code by launching the X++ code editor.

X++ has a lot of features and tools that help you edit the structure of the application and avoid common programming pitfalls that can prevent you from implementing X++. It includes keywords that match most of the keywords in standard SQL.

Using Code Access Security

The CAS framework is a mechanism developed to protect systems from dangerous APIs that are invoked by untrusted code. It simply allows two pieces of code to communicate in a manner that can't be compromised.

To know what untrusted code is, we will first define what trusted code is. Trusted code is defined as code from the AOT running on the Application Object Server (AOS), meaning the code must be written by a trusted developer. This is because the developer privileges and permissions are the highest level of permission over the entire application. In other words, if you execute the code outside the AOS on a client, there is the possibility that it was altered on the client side before execution, thus rendering the code untrusted. The following figure demonstrates this mechanism:

Using Code Access Security

Tip

For more information on CAS, visit Microsoft MSDN: http://msdn.microsoft.com/en-us/library/ff648663.aspx.

The main purpose of CAS is securing the tunnel between an API and its consumer...

Security debugging

The debugger tool provides debugging capabilities for X++ developers and it also communicates with the Microsoft Dynamics AX client, .NET Business Connector, or batch jobs that run on the Microsoft Dynamics AX server.

We're going to illustrate the following:

  • Installing the debugger tool
  • Enabling the debugger tool
  • Adding users to the debugging user local group
  • The debugger user interface
  • Debugger shortcut keys

First you have to make sure you have installed the debugger tool from Microsoft Dynamics AX. Go to Setup | Install | Microsoft Dynamics AX components.

Installing the debugger

In this section, we will see how to install the debugger tool.

From the Microsoft Dynamics AX 2012 Setup window, you can install the debugger to add, remove, or modify any component that is installed or should be installed:

Installing the debugger

To begin installing the debugger component, go through the following steps:

  1. From the Microsoft Dynamics AX Setup window, go to Install | Microsoft Dynamics AX components.
  2. Provide...

Security for the display and edit methods

The display method is not a physical field in a table but is a method to display information from another table or resource. In simple words, it can expose data from any table that includes the display keyword as a method modifier. The methods that can use the display method modifier are as follows:

  • Table
  • Form
  • Report
  • Report Design
  • Data Source

Note

The display method modifier is any method that includes the display keyword as a method modifier. It indicates that the method has a return value that can appear on a form or a report.

The following example is a standard display method from the SalesTable table:

display CustName customerName()
{
    return this.partyTable_CustAccount().Name;
}

To create a display method, follow these steps:

  1. Place the display keyword in front of the method's return type. For example:
    display Amount amount()
  2. Determine the return type. The return type should be an extended data type. A display method returns a calculated value like...

Working with security in AX2012 is quite different compared to earlier versions of Dynamics AX. One huge difference is the need to have some basic understanding of how security is defined within the application itself. This book starts off with laying down some basics of how security artifacts are defined in the AOT and further builds on top of that skillset. Debugging your security is covered, and also how security through the Extensible Data Security (XDS) is setup in Dynamics AX. The final chapters discuss how to extend the organization model and finally how to secure your Enterprise Portal (EP) artifacts.It is a compact book with less than 80 pages and a handful chapters. The content is built for Dynamics AX2012 R3, but is relevant for earlier versions of AX2012. If you're already an AX developer, you can skip over most of developer basics. As someone who is curious to understand the mechanics under the hood, I could have wished for more in depth details, but the book does a fairly well job covering security for AX2012 R3.

Security in Dynamics AX is a crucial area often overlooked in normal AX implementations. In AX 2012, security has become more significant due to the complexity and scale of standard functionalities and features of the product. Therefore I went through this book with much interest. There are plenty of security related info for both experienced and novice AX developers and administrations in this book.The author has covered security aspects such as CAS, TPF and XDS so credit to him. The technical details covered in the book are accurate. The book also briefly touches up on an interesting but often overlooked feature called 'organization hierarchies'. I would have liked to see contents such as end to end example such as managing security roles and underlying processes such as assigning users to this role etc, explanation of pain points surrounding security, security development tool (which works with R3 version) etc. But overall, this book offers decent insight into the security domain within Dynamics AX.
