Disable Code Access Security

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :.NET Framework

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.

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.

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.

Security: Manipulate Privileges in Managed Code Reliably, Securely, and Efficiently


When the author was faced with implementing support for changing a security descriptor on an object, he noticed there was not support for that operation in .NET. So he devised two solutions to the problem: the first, simpler one, is tailored to the .NET Framework 1.1 and can be used today. The second solution incorporates several advanced features available only in the .NET Framework 2.0. Both are presented here.

Security Briefs: Access Control List Editing in .NET


Access control lists (ACLs) can be complex beasts, and user interfaces for editing them are incredibly tricky to implement properly. That's why I was really excited when Windows® 2000 shipped with a programmable ACL editor, shown in Figure 1.

Attack Surface: Mitigate Security Risks by Minimizing the Code You Expose to Untrusted Users


In this article, Microsoft security expert Michael Howard discusses the cardinal rules of attack surface reduction. His rules - reduce the amount of code executing by default, reduce the volume of code that is accessible to untrusted users by default, and limit the damage if the code is exploited - are explained along with the techniques to apply the rules to your code.

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.

Security Tips: Defend Your Code with Top Ten Security Tips Every Developer Must Know


There are many ways to get into trouble when it comes to security. You can trust all code that runs on your network, give any user access to important files, and never bother to check that code on your machine has not changed. You can run without virus protection software, not build security into your own code, and give too many privileges to too many accounts. You can even use a number of built-in functions carelessly enough to allow break-ins, and you can leave server ports open and unmonitored. Obviously, the list continues to grow. What are some of the really important issues, the biggest mistakes you should watch out for right now so that you don't compromise your data or your system? Security experts Michael Howard and Keith Brown present 10 tips to keep you out of hot water.
