ExamGuru IT/.Net Guru : System.Security.PermissionSet Class [Articles]

C# allows developers to embed XML comments into their source files—a useful facility, especially when more than one programmer is working on the same code. The C# parser can expand these XML tags to provide additional information and export them to an external document for further processing. This article shows how to use XML comments and explains the relevant tags. The author demonstrates how to set up your project to export your XML comments into convenient documentation for the benefit of other developers. He also shows how to use comments to generate help files.

Code Access Security

C#Today

With the .NET strategy evangelizing loosely coupled component development, the designers of .NET had to come up with security strategies that helped to control these potentially dangerous components. The .NET framework introduces two main models for securing your application: code based security, and role based security. In this article, the first of a week-long topic on security, Kaushal Sanghavi discusses the .NET frameworks for security, and demonstrates how we can use permissions in code. Later in the week, he will also tackle custom security permissions, custom security implementation, and integrating COM+ and .NET security schemes.

Custom Permissions

C#Today

Any multi user system needs to have a concept of security to protect one users data from another. This security element could be anything from granting or denying a user access to a file, a network share, or certain entities in a database. These security mechanisms are controlled via the use of Permissions. Before the advent of .NET, using permissions in application code was hard, but now the framework allows a very open and extensible permission architecture. In this article, the third of the week's security-based articles, Kaushal Sanghavi explores the support that the .NET framework offers for working with permissions, and demonstrate how developers can design their own custom permissions to control access to protected data.

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

MSDN

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.
