.NET is the most popular and also the most powerful software framework that is primarily made for the Windows Platform. As robust and critical applications are being created in this framework that might be used to administer sensitive data, security in coding pattern of this framework is a paramount necessity. Microsoft has been potent to maintain a strong hold in every security issues, therefore, this framework by Microsoft is of no excuse. Guidelines has been connoted by this IT giant for secure coding for this framework. While securing the application’s codes, it must be emphasized that its usability is not hampered.
Security-Neutral codes are to be used to take advantage of .NET technology. This enables a Security Exception for codes that do not have the correct security permission in the API. In addition to this, any application code that is called must have the same permission as the corresponding code to work properly. Thus, using security-neutral code it is possible to build an exceptionally secure application.
Codes implementation should be done along with wrappers. Create managed wrappers using platform invoke or COM Interop for native codes that are to be used to manage codes. The wrapper codes should be given the rights to unmanaged codes so that the callers of the wrapper could perform efficiently.
Library can be used to protect resources, as the library acts as an interface to codes that needs access to resources. The program should be coded in such a way that codes that require access to resource undergoes a security check. Thus, the codes will require a permit before they access a resource in the library. Along with this, rights must be asserted to particular library functions to perform the operation.
In addition to these coding practice method level encryption tools can be used. Various encryption tools can be used from third party vendors such as VMware, V I Labs, Xenecode among many others.
