Are You in the Know?: Find Out What's New with Code Access Security in the .NET Framework 2.0


Unlike role-based security measures, code access security is not based on user identity. Instead, it is based on the identity of the code that is running, including information such as where the code came from. Here Mike Downen discusses the role of code access security (CAS) in .NET and outlines some key new features and changes in CAS for the .NET Framework 2.0.

Return of the Rich Client: Code Access Security and Distribution Features in .NET Enhance Client-Sid


Rich clients employ many of the features and conveniences of the operating system they run on, and the list of these features has been growing since the dawn of the PC. But as apps have migrated to the Web, the trend towards increasing client-side functionality has ground to a virtual halt. There are several reasons for this; chief among them are security and deployment problems. But that's all about to change. With the .NET Framework, you can participate in building the distributable rich client of the future. In this article, the author enumerates the pertinent features of .NET that will allow you to build safe, easily deployable controls. The features discussed include managed code, code access security, versioning control, Windows Forms classes, and isolation.

Security in .NET: Enforce Code Access Rights with the Common Language Runtime


Component-based software is vulnerable to attack. Large numbers of DLLs that are not tightly controlled are at the heart of the problem. Code access security in the Common Language Runtime of the Microsoft .NET Framework addresses this common security hole. In this model, the CLR acts as the traffic cop to assemblies, keeping track of where they came from and what security restraints should be placed on them. Another way the .NET Framework addresses security is by providing preexisting classes which have built-in security. These are the classes that are invoked in .NET when performing risky operations such as reading and writing files, displaying dialog boxes, and so on. Of course, if a component calls unmanaged code, it can bypass code access security measures. This article covers these and other security issues.

Adding logic to the Search Core Results web part - Manipulation in code or XSL?

Hi,I need to manipulate the search core results web part, so that:- It will display a check box for each result- It Will have an additional button. When clicking on this button the checked results should be copied to a grid view.Do you have any idea how it can be done?I am not sure what is the correct way to do it – in the client side via the XSL Editor or in the server side with the C# code.Thank you so much for your help,Regards,SP beginner.

Disable Code Access Security


I m having an application where I loads dlls dnamically and from that loaded dll is use to read some machine settings,files etc. I want full access for my application so I want to disable CAS setting for my application.

I have tried "SecurityManager.SecurityEnabled =  false" but I m failing to set this property from my application.

I have tried caspol -security off from VS command prompt but from my code I always gets TRUE for SecurityManager.SecurityEnabled.

I m using CLR v2.0

Please let me know how I can disable CAS from my application.



Issue with Code Access Security Policy - deploying a third party dll to bin


Okay, i think most of you guys out there use wspbuilder to build the wsp solutions and to deploy it. So here is my problem.

I'm working on a SharePoint solution which makes use of a third party dll (Telerik for Asp.Net Ajax - Telerik.Web.UI.dll) for rich experience. Since Telerik dll is a common assembly i have to deploy it to the bin folder of the webapplication instead of GAC. So here comes the problem.

WSPBuilder automatically deploys the dll to gac if the dll presents in the GAC folder. To deploy the telerik dll in bin i created the folder 80\bin and copied the dll there. I tried to build the wsp again and then went through the manifest.xml created. Great. The deployment target for the dll changed to WebApplication and wspbuilder was smart to create the cas policy itself.

Code Access Security Policy Tool (Caspol.exe) - detailed description



          I am studying for MCTS - 70-536 , I want more details about caspol utility, its command line options. I have gone through the Link http://msdn.microsoft.com/en-us/library/cb6t8dtz%28VS.80%29.aspx and the MCTS - 70-536 Self Paced Training Kit , 2nd Edition, but I could not find its detailed command line options. Please refer any book or link which can give extensive details about caspol utility.

Thank You

Data Points: The Enterprise Library Data Access Application Block, Part 3


E nterprise applications can have a wide variety of data update requirements. Sometimes you need to save multiple rows of changes at once within a single transaction. Other times, the user must be allowed to enter multiple rows of data, send them to the database in a batch; and if a row or two fails, only the rows that succeeded should be committed and remain committed.

Data Points: The Enterprise Library Data Access Application Block, Part 1


A solid data access later (DAL) can benefit an application by hiding redundant tasks, helping handle exceptions more gracefully, helping clean up resources more efficiently, and providing a layer of abstraction from the database.
