Declarative RBS Demands
In the .NET Frameworks environment and programming contexts, security and improved access rights and priviledges, security policies and more get lots of attention. There are powerful ways to ensure integrity and protection for users, systems, data and more.
The Assertive System.SecurityCryptography namespace is used for encrypting and decrypting data. System.Security.AccessControl namespace is used for access to the DACLs, SACLs, and ACLs (see defined elsewhere). Also, authorization and authentication processes, stemming from a need for increased User and Data Security, Access, let us take a harder look at how these functionalities can help, hinder and strenghten applications, code and outcome.
There are some specific restrictions that are declared as an attribute to a method and that instruct the runtime to performance access check before running the method. This is a strategy and tool for ensuring that access to methods are restricted. It is basically a run-time instruction that demands an RBS check before running a method. It restricts access to code, through enforced security. Can only be used on whole methods, not portions or pieces, specifics, might also result in exceptions, applications may stop operating or running, recording an event.
Code for declarative RBS Demands will need three things:
Specifying the base and principal security policy: (i) System.AppDomain.Current Domain.SetPrinciplePolicy (ii) underprivileged access attempts and error-reporting (try/catch block), (iii) Principal.Permission attribute to declare methods access requirement. For Windows Security , settings to Windows Principal is required, to work against failures, errors and exceptions.
This remains by far, one of the most secure ways, to use RBS to restrict access to code because security is enforced by the runtime before it runs your code.
