Writing Secure Code using C#
Apr 06, 2001.
Code access security is a mechanism that grants/denies access to resources within a method call. For example, code written by a person may be allowed to write to the disk while code from another one may be forbidden from accessing the disk. This control can be enforced even if the code written by both of them is used within a single application

Understanding How Assert Effects Security
Apr 25, 2001.
Assert is a security action that is evaluated at run time. Code Access Permission classes and Permission Sets support a method called Assert.
