Security and Cryptography

Abstract

A principal goal of the Microsoft .NET Framework is to make computing more secure, especially with respect to the use of mobile code and distributed systems. Most modern operating systems (including Microsoft Windows) support user-based security, allowing you to control the actions and resources to which a user has access. However, in the highly connected world resulting from the proliferation of computer networks, particularly the Internet, it’s insufficient to base security solely on the identity of a system’s user. In the interest of security, code should not automatically receive the same level of trust that you assign to the person running the code.
