Authorization is the act of checking whether a user has permission to conduct some action. Whereas authentication is about verifying identity, authorization is about verifying a user s authority. To give a concrete example, let us examine the case in which Alice authenticates herself at an ATM by putting in her ATM card and entering her PIN. Alice may want to deduct $500, but may only be authorized to deduct a maximum of $300 per day. If Alice enters $500 as the amount that she is requesting to deduct, the system will not authorize her transaction even if she successfully authenticates herself. In the previous example, an authorization check questions whether Alice has the authority to deduct a certain amount of money. Operating systems such as Windows and Linux do authorization checks all the time. For example, when Alice attempts to delete a file, the operating system checks whether Alice is allowed to do so. A general mechanism called an access control list (ACL) is used by many operating systems to determine whether users are authorized to conduct different actions.

Minimally, an ACL is a set of users and a corresponding set of resources they are allowed to access. For example, Alice may have access to all the files in her home directory,1 but may not have access to Bob s files. Suppose Alice s home directory is /home/Alice, and Bob s home directory is /home/Bob. An ACL that models this would list Alice as the principal,2 and it would also list the set of files in her home directory that she is allowed to access, as shown in Table 1-1. In the table, an asterisk (*) is used as a wildcard to indicate all files and subdirectories within a particular home directory. An ACL may optionally include privileges that are associated with resources. The Privilege column indicates that Alice and Bob are allowed to read, write, and execute files in their respective home directories. Table 1-1. A Simple ACL

WF itself is a programming model, along with an engine and a set of tools for building workflowenabled applications. The programming model is made up of exposed APIs that other programming languages can use to interact with the workflow engine. These APIs are encapsulated within a namespace called System.Workflow. That namespace will be part of the WinFX programming model, but can also be installed as an add-on to the existing .NET Framework 2.0. The easiest way to interact with the new APIs and namespace is through the Workflow Designers, which you can add onto VS2005. You must download and install WF (more on this in the next section) unless you re using Windows Vista as your operating system. When you download and install the foundation, WF gets bolted onto the .NET Framework 2.0 and VS2005. Within VS2005, you ll have new project types and will be able to import and use the System.Workflow namespace. The new Workflow Designer projects allow you to design workflow visually using the same drag-and-drop methods you use for creating Windows or Web-based applications. Within the designers, you build workflow much like you d create a flowchart with a tool such as
