OPUS: Online Patches and Updates for Security

We present OPUS, a tool for dynamic software patching capable of applying fixes to a C program at runtime. OPUS’s primary goal is to enable application of security patches to interactive applications that are a frequent target of security exploits. By restricting the type of patches admitted by our system, we are able to significantly reduce any additional burden on the programmer beyond what w...

Surveillance Or Security? The Risks Posed by New Wiretapping Technologies

The United States has moved large portions of business and commerce, including the control of critical infrastructure, onto IP-based networks. This reliance on information systems leaves the U.S. highly exposed and vulnerable to cyberattack. Yet despite this, U.S. law enforcement and national security policy remain firmly focused on building wiretapping systems within communications infrastruct...

Metastable Regimes for multiplexed TCP flows

Consider the mean field limit of a model for multiple HTTP sources multiplexed through a drop-tail router. The limit may exhibit two stationary regimes. In the fluid regime the flows are independent, there are no packet losses and the average throughput is high. In the turbulent regime the flows are synchronized, there are periodic congestion epochs with packet losses and the average throughput...

Technologies of Suspicion: Coercion and Compassion in Post-disciplinary Surveillance Regimes

Drug-use surveillance systems appear in this paper as symptomatic “technologies of suspicion” that constitute a set of empirical modes for producing and interpreting “data” or test results in ways that conflate prediction with prescription, acting as technological forms of supervision, monitoring, supposed deterrence, and ultimately control. Technologies of suspicion are predicated upon a frame...
