I am currently a candidate for M.A.Sc. in the Computer Engineering group at the University of Toronto. I am interested in the areas of Distributed Systems and Computer Security.
My recent work is targetted towards how to design a computer system that can perform intelligent selective recovery from full or partial failures. Such failures could have resulted from program errors, administrator misconfigurations and hostile intruders. One of the major difficulties of automating such a selective recovery system is that determining the exact fit of "tainted" system state automatically is a very challenging problem. What typically results is a set of tainted data that may include some set of false-positives (valid system state modifications that were marked tainted) and false-negatives(invalid system state modifications that were missed during the error detection stage). My contributions to this project will involve the design of a system to allow humans to more easily guide the auditing to provide a closer fit to decrease false-positives and false-negatives in the tainted set.
