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.

Review It: Expert Tips for Finding Security Defects in Your Code


Reviewing code for security defects is a key ingredient in the software creation process, ranking alongside planning, design, and testing. Here the author reflects over his years of code security reviews to identify patterns and best practices that all developers can follow when tracking down potential security loopholes. The process begins by examining the environment the code runs in, considering the roles of the users who will run it, and studying the history of any security issues the code may have had. After gaining an understanding of these background issues, specific vulnerabilities can be hunted down, including SQL injection attacks, cross-site scripting, and buffer overruns. In addition, certain red flags, such as variable names like "password", "secret," and other obvious but common security blunders, can be searched for and remedied.

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.

Authentication for External Users to Access MOSS 2007 Resources

Our MOSS 2007 supports users from two domains that authenticate using windows.  Our clients WindowsXP in domain#1 and WindowsVista in domain#2 (which has presented problems authenticating to MOSS 2007.  I would like to give access to external users outside of those two domains.  However, our management does not want to establish trusts between domains.  What would be the best practice to accomplish this?  Additionally, will MOSS 2010 or Forefront resolve these issues?

MOSS 2007 - Error Code 500 after click on Ok button on a post reply with an accent charactere in the



I have this strange behavior in my test and prod environment but not in my Dev.

The case is as following:

  1. Someone create in a discssion list a topic with an accent charactere in the title.
  2. Someone else click on the reply button. then he write the post.
  3. Then he click on the Ok button and a code error 500 page is loaded.

In the same discussion list If the title of the topic does'nt contain any accent charactere it works well !

Regional settings of the site collection are strictly identical on Dev, test and pro environment.

Does someone have any Idea ?

Thanks in advance for your answers

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.
