Abstract: Just as we should not expect our base programming language to provide all the data types we need, so we should not expect our security foundation to provide all the abstractions we need to express security policy. The answer to both is the same: We need foundations that provide simple abstraction mechanisms, which we use to build an open ended set of abstractions, which we then use to express policy. We show how to use EcmaScript 5 to enforce the security latent in object-oriented abstraction mechanisms: encapsulation, message-passing, polymorphism, and interposition. With these secured, we show how to build abstractions for confinement, rights amplification, transitive wrapping and revocation, and smart contracts.
