MOOC on Software Security

I am a professor in the Computer Science Department and UMIACS at the University of Maryland, College Park. With Jeff Foster and David Van Horn I direct PLUM, the lab for Programming Languages research at the University of Maryland. I am also affiliated with the Maryland Cybersecurity Center (MC2), and was formerly its Director (see our video!). You may find it interesting to read about how we manage PLUM.

Here is my current vita and a list of my publications, organized by year and by category.

I received my Ph.D. in Computer and Information Science from the University of Pennsylvania in August 2001, and I spent one year as a post-doctoral associate affiliated with the Information Assurance Institute of the Computer Science Department at Cornell University. During academic 2008 - 2009, I was on sabbatical in Cambridge, England. From September to November I was at Microsoft Research and from December to August 2009 I was at the University of Cambridge Computer Laboratory. I was the director of MC2 from October 2011 to 2013. During the Summer of 2015 I visited Microsoft Research in Redmond.

Research

My primary research interest is to develop and evaluate techniques to improve software availability, reliability, and security. I am currently working on a number of projects.
Secure Programming - How do we build software that is secure? We have been developing a contest, called build-it, break-it, fix-it whose aim to test how well students can build software securely. We have now offered the contest several times and have some interesting preliminary analysis of what strategies work and don't work for building and breaking.
Protecting against side channel attacks - How do we avoid leaking information via observable behavior? We are developing novel static analyses and type systems to identify when a program might be leaking sensitive information via its running time, space usage, address/IO trace, and more.
Quantifying Information Flow - means to enforce security policies through programming languages and analyses that carefully consider (and quantify) information flows. We have implemented approaches using probabilistic abstract interpretation for protecting static and time-varying secrets, and we are currently generalizing these ideas to database queries.
Blending Programming Languages and Cryptography - means of implementing privacy-preserving or integrity-assuring computation through the combination of programming languages and cryptographic techniques. I have looked at languages and analyses for secure multiparty computation, most notably a new programming language called Wysteria, and developed novel mechanisms for cloud-based computations involving general-purpose authenticated data structures and compiler-optimized oblivious RAM.
Dynamic Software Updating (DSU) - means to safely, efficiently, and flexibly update running code. We have developed general-purpose methods for updating C and Java programs, and are currently considering means to update controllers in software-defined networks. Our system for dynamically updating C code is called Kitsune and our system for Java is called Rubah; the code and benchmarks for both are freely available. I have most recently considered DSU for key-value stores and software-defined networks. Earlier work and papers are described here.

Previously, I was involved in the following projects:

  • Adapton, a library for incremental computation --- the idea is to write an algorithm largely as usual, but then to derive a version that can incrementally update the output following a small changes to its input.
  • Expositor, a library for writing dynamic analyses to assist in debugging, taking advantage of record/replay support.
  • Diamondback Ruby, static and hybrid static/dynamic type system for the Ruby scripting language. 
  • Otter, a symbolic executor for C programs.
  • LockSmith, a static analysis tool for proving the absence of race conditions in C programs.
  • Path Projection, a browser-based UI toolkit for presenting, navigating, and querying paths emitted as static analysis results; we applied it to Locksmith.
  • Cyclone, a safe dialect of C.
  • I have also looked at means for customized, language-enforced security policies, implemented in a web programming language, SELinks, and automatically inserted by a compiler called Coco.

I have an interest in systems and networking as well, and for a while I worked on measurement-aware data transport and kernel-based rootkit detection. Links to all past projects may be found on the PLUM home page.
