Language-based system

In a language-based system, the operating system has both the kernel and applications implemented using a high level programming language, such as Java. [cite web

Protection

In a language-based protection system, the kernel will only allow code to execute that has been produced by a trusted language compiler. The language may then be designed such that it is impossible for the programmer to instruct it to do something that will violate a security requirement.
