Object Capabilities for Security Google Tech Talks November, 30 2007 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. Speaker: David Wagner David Wagner is an Associate Professor in the Computer Science Division at the University of California at Berkeley with extensive experience in computer security and cryptography. He and his Berkeley colleagues are known for discovering a wide variety of security vulnerabilities in various cellphone standards, 802.11 wireless networks, and other widely deployed systems, and he has published two books and over 90 peer-reviewed scientific papers. David is a founding member of the ACCURATE center on electronic voting. He is active in the areas of systems security, cryptography, and electronic voting.

Starpoint - Object Of My Desire (1985) A tribute to both the late but beautiful Renée Diggs who passed away in 2005 due to a heart condition, and fellow bandmember and Diggs' longtime companion, Ernesto Phillips, who sadly also passed away a year earlier as the result of a stroke. In 1985 Starpoint recorded their seventh album "Restless", and toured extensively that year. The album sold over 600,000 records and went "Gold" with Renée singing the hit single,"Object Of My Desire". In the middle of the "Restless" tour, she was diagnosed with Multiple Sclerosis (MS). It made it hard for Starpoint to continue touring. Her voice cuts through the air with a magical tone. Her high notes soar through the sky with a chilling presence and clarity. With her charm, beauty and fantastic vocal ability, she is deeply missed. Ernesto and Renée both played a large part of the success that Starpoint reached. May they both R.I.P.
