Code Access Security (CAS) is a security model used in the Microsoft .NET Framework that helps to protect users and their systems from the potentially harmful effects of running untrusted code. It establishes a way to control the permissions granted to code based on several factors, including its origin, the identity of the user executing the code, and the security level of the operating environment.
