Gossip based aggregation protocols are a promising approach to monitoring large-scale decentralized IT infrastructures. Compared to traditional approaches they exhibit good properties of scalability, tolerance of churn, and communication overhead. Gossip-based protocols can compute statistical aggregates such as the average, sum or statistical distribution of an attribute across a large system. However,...
Compiler and architectural techniques can play a vital role in dependability enhancement of applications. These techniques have traditionally been focused on performance enhancement. However this trend is changing as reliability and security are becoming first-class constraints for application design. The goal of the workshop is to provide a common platform for researchers in the dependability community...
To achieve end-to-end security, traditional machine-to-machine security measures are insufficient if the integrity of the human-computer interface is compromised. GUI logic flaws are a category of software vulnerabilities that result from logic bugs in GUI design/implementation. Visual spoofing attacks that exploit these flaws can lure even security- conscious users to perform unintended actions....
This paper combines an analysis of data on security vulnerabilities (published in the Bugtraq database) and a focused source-code examination to: (i) develop a finite state machine (FSM) model to depict and reason about security vulnerabilities; and (ii) to extract characteristics shared by a large class of commonly seen vulnerabilities (e.g., integer overflow, heap overflow, format string, and stack...
