    Overview

    The Java 2 platform provides a means to enforce access controls based on where code came from and who signed it. These access controls are needed because of the distributed nature of the Java platform where, for example, a remote applet can be downloaded over a public network and then run locally.

    However, the Java 2 platform does not provide a way to enforce similar access controls based on who runs the code. To provide this type of access control, the Java 2 security architecture requires the following:

    The Java Authentication and Authorization Service (JAAS) framework provides these enhancements.

    For a general overview of JAAS, see the following Web site:
