Applying Flex Security

Macromedia Flex security is based on the Macromedia Flash Player security model, which runs the player within a security sandbox. All Flex applications are sent to the client as a SWF file, therefore, Flex applications benefit from the robust security sandbox model used by standard Flash applications.

In addition, the Flex application is a J2EE-compliant web application, and as such, it can use any security implementation that is appropriate for that environment.
