Detecting Deadlock in Programs with Data-Centric Synchronization

In Proceedings of the 35th International Conference on Software Engineering (ICSE ’13)

A Safety-First Approach to Memory Models

IEEE Micro Top Picks, Volume 33, Number 3, May/June 2013
The concurrency semantics of mainstream programming languages provide "safety" only under the assumption that programmers have implemented proper synchronization to prevent data races. But since simple programming mistakes can break this assumption and result in unreliable program behavior, we argue instead for providing a safety-first model that assumes an access may participate in a data race unless proven otherwise.

A Data-Centric Approach to Synchronization

ACM Transactions on Programming Languages (TOPLAS), Volume 34, Issue 1, April 2012
Concurrency-related errors, such as data races, are frustratingly difficult to track down and eliminate in large, object-oriented programs. We describe AJ, and extension to Java, which uses a declarative, data-centric synchronization paradigm that eliminates a large class of concurrency bugs with low programmer effort.

Visual Analytics for BGP Monitoring and Prefix Hijacking Identification

IEEE Network (Volume: 26 , Issue: 6 , November-December 2012)
In this article, we give a short survey of visualization methods that have been developed for BGP monitoring, in particular for the identification of prefix hijacks. Our goal is to illustrate how network visualization has the potential to assist an analyst in detecting abnormal routing patterns in massive amounts of BGP data.

pdf
File Routing Middleware for Cloud Deduplication

In Proceedings of the 2nd International Workshop on Cloud Computing Platforms (CloudCP ’12)
We propose the idea of performing local deduplication operations within each cloud node, and introduce file similarity metrics to determine which node is the best deduplication host for a particular incoming file. This approach reduces the problem of scalable cloud deduplication to a file routing problem, which we can address using a software layer capable of making the necessary routing decisions.

Ask WINE: Are We Safer Today? Evaluating Operating System Security through Big Data Analysis

In Proceedings of the 5th USENIX Workshop on Large-Scale Exploits and Emerging Threats (LEET '12)
In this position paper, we argue that in order to answer conclusively whether end-users are safer today, we must analyze field data collected on real hosts that are targeted by attacks—e.g., the approximately 50 million records of anti-virus telemetry available through Symantec’s WINE platform.

Robust and Fair Machine Learning, Data Mining, and Artificial Intelligence

The tremendous growth in the learning capacity of Machine Learning methods has yet to be met with a corresponding growth in our ability to understand these models. Equally troubling, our ability to build robust machine learning models has not kept pace with research in adversarial attacks against machine learning. As we increasingly hand over decision making to automated machine learning and AI systems, we must find ways that the life-altering decisions made by these systems can be audited for fairness, safety, robustness to adversaries, and the preservation of privacy of any personally identifiable information over which they operate.
