Sotirios Apostolakis will present his general exam on Wednesday, May 24, 2017 at 3pm in CS 401. 

The members of his committee are: David August (adviser), Nick Feamster, and Andrew Appel. 

Everyone is invited to attend his talk and those faculty wishing to remain for the oral exam following are welcome to do so. His abstract and reading list follow below. 

Enabling Practical Full System Containment 


Acknowledging that modern computing systems are too complex to be vulnerability free, we advocate for a single, simple component that would quarantine the ill effects of compromised system components. Work on a system called TrustGuard has shown that it is feasible for a simple and pluggable hardware element, called the Sentry, to offer containment of untrusted hardware, by ensuring that the system only outputs results of correct execution of signed programs. TrustGuard’s original focus was to protect against hardware vulnerabilities and signed programs needed to be entirely trusted. This work extends TrustGuard’s checking scheme with a new programming model. This new model exposes the Sentry to programmers by allowing them to reduce the amount of code that is trusted and checked by the Sentry. We implemented a library for runtime integrity checking of key-value database operations to demonstrate the practicality of the enhanced checking scheme and exemplify how Sentry produces trusted output using untrusted applications, OS and hardware.
