ABSTRACT
Existing systems often do a poor job of meeting the principle of least privilege. I will discuss how object capability systems and language-based methods can help address this shortcoming. In language-based object capability systems, an object reference is treated as a capability; unforgeability of references ensures unforgeability of capabilities; and all privileges are expressed as capabilities in this way. This makes it possible to decompose the system into distrusting "privilege-separated" components, providing each component with the least privilege it needs to do its job; to reason about the privileges and powers available to various program elements, often in a local (modular) way; and to avoid common pitfalls, such as confused deputy and TOCTTOU vulnerabilities.
I will attempt to introduce the audience to some work in this area that is perhaps not so widely known, and I will describe some work in progress to construct a subset of Java, called Joe-E, that is intended to enable capability-style programming using a programming syntax that is familiar to Java programmers.
