Use PDFOne to export PDF pages to image formats. Now that we ve seen at a high level how custom security works, let s examine its implementation details. 15.4.1 Design goals and tradeoffs Here is our hypothetical scenario. In chapter 11, we discussed a possible approach that Adventure Works Cycles can follow to implement the My Orders feature. As you will probably recall, this feature allows AWC web-based customers to view their order history. The implementation approach in chapter 11 relied on the AWReportViewer control for rendering the Customer Orders report via SOAP on the server side. Let s now change our implementation approach by allowing the customers to request the report by URL on the client side of the application. This approach has a number of advantages, including simplicity and a rich user experience. Because the report is now requested by URL, we can add interactive features to the report, such as toggling visibility, drilldown, and so on. While we can reap the benefits that URL access has to offer, we shouldn t compromise the application s security in doing so. To ensure secure access to the Report Server, we will use a custom security extension to authenticate and authorize the report requests. Here are the high-level requirements for our solution: Allow customers to access reports by URL. Enforce restricted access to the Report Server by implementing a custom security extension. Authenticate users against a user profile store. In our case, the profile store will be represented by the Individuals table in the AdventureWorks2000 database. java pdf to image library: Convert PDF To High-Resolution Images Using Java - Gnostice java pdf to image high resolution Get a page from pdf and save it to an image file with itext - Stack ...

Implement horizontal data filtering at the data source based on the user s identity to ensure that a customer can see only her own orders Implement the necessary infrastructure to provide administrator-level access to the Report Server using a designated admin account Support assigning customers to groups for easier maintenance Creating role-based security policies for hundreds and thousands of web customers is impractical Instead, a better approach would be to assign customers to groups, for example, Individual or Store groups, to reflect the existing customer types in the AdventureWorks2000 database Our implementation will be a subject to the following tradeoffs: To keep the solution as lightweight as possible, we won t require the customer to enter a password Needless to say, in real life, you should provide as robust authentication as possible The Microsoft custom security sample shows you some practical techniques for using strong passwords.

Once again, consider using SSL to secure the connection to the Report Server For the sake of simplicity, we won t provide the database infrastructure needed to support organizing customers in groups Instead, we will use the customer s identifier as a user name and a hard-coded group name called Individual During the authorization stage, we will check the name and, if it is a valid number, we will assume that the customer belongs to the Individual group In real life, your authorization logic will typically make a database call to determine the level of access the user has based on his group membership Unlike the Microsoft custom security sample, we won t be implementing a login form to log the user to the Report Server in case the session has expired or the user has bypassed the application authentication. Answers to these questions and explanations of why each answer choice is correct or incorrect are located in the Answers section at the end of the book. In our opinion, having too many login screens may be confusing for the user and may present a security risk Instead, our design pattern promotes a single logon to both the application and the Report Server, which will be the responsibility of the application In cases where the user requests an RS resource without being authenticated or the RS cookie session has expired, we will display an error page and prompt the user to log in again to the web application Now, let s see how our solution works from an end-user perspective 1542 Intranet reporting with custom security We will assume that the Adventure Works customers have been already registered and their profile data is captured in the Individual table The first step that the report administrator needs to do is grant the users access to view the appropriate reports.. 1.
