Open Data Handbook

This handbook discusses the legal, social and technical aspects of open data. It can be used by anyone but is especially designed for those seeking to open up data. It discusses the why, what and how of open data – why to go open, what open is, and the how to ‘open’ data.

Particle Discovery and the Role of Bayes in Design of Hypothesis Tests

Statistics Colloquium

Tuesday, Feb 21st at 4pm in Clark 107, University of Virginia

Speaker:  Richard Lockhart from Simon Fraser University

The discovery of the pentaquark, announced in Stepanyi et al (2003). Phys Rev Lett, 91, 252001, illustrates the problem of finding bumps in histograms as evidence of the existenceof hitherto  undetected particles.  The later retraction of a claim based on a P-valuebelow 3 parts in a billion illustrates the need for some care in designing hypothesis tests. I will discuss the Poisson process models used and the resulting tests for missing components in a mixture.  I propose to apply prior distributions describing the sought after bump and indicate the nature of resulting Neyman Pearson tests.  The discussion has a few features which I think merit attention: 1) I recommend the use of sample size dependent priors to design good tests; 2) I draw an analogy between this problem and goodness-of-fit; 3) I am led to test statistics whose asymptotic law is that of the integral of a log-Gaussian process. If I have time I will discuss the potential use of priors in testing ill-defined null hypotheses.

Lethal Autonomous Robots and Responsibility

Science, Technology, and Society Program
Spring 2012 Colloquium Series
Date:  Thursday Feb. 23,  2012
Time:  3:30 – 5:00 p.m
Location:  Rodman Room, Thornton Hall, University of Virginia

In the second STS colloquium talk of 2012 Merel Noorman, a postdoc at the STS department, will present her current research on autonomous military robots and responsibility. One of the primary ethical concerns about future military robots is that these technologies will further obfuscate the distribution of responsibility, as they become more complex and increasingly capable of autonomous operation. Who will be held responsible when these robots make life and death decisions? In her talk, Merel will take a closer look at the discourse on autonomous military robots in order to explore how we can best address such concerns.

Toward Proactive Mitigation of Advanced Multi-tier Botnets

Topic

Toward Proactive Mitigation of Advanced Multi-tier Botnets

Date and Time

February 8, 2012 from 5 pm – 6 pm

Abstract

In this talk I will present our on-going efforts to mitigate the advanced botnets. Botnet is a network of compromised machines, exploited to carry out malicious acts such as spam, phishing, denial of service attacks, and stealing sensitive data such as passwords and banking credentials. The detection and mitigation of these botnets have proven to be quite challenging. Malware authors, supported by a thriving underground economy, have demonstrated professional quality sophistication in creating codes highly adaptive to existing mitigation efforts.

We have explored a series of botnet mitigation approaches directed toward (i) creating new analysis and de-obfuscation methods to rapidly expose the botnets’ command and control protocols in a timely manner, (ii) in-depth analysis to explore the fundamental limits and weaknesses of the advanced botnet architecture, and (iii) designing an effective enumerator (or “mapping” of bot networks) to locate bot-infected hosts on the Internet.

Our research direction fundamentally differs from existing Intrusion Detection System (IDS) approaches. Unlike IDS, which is geared towards protecting local hosts within its perimeter, an enumerator will enable identification of both local and remote infections. Identifying remote infections is crucial, given that there are numerous computers on the Internet that are not under the protection of IDS-based systems. The resulting enumeration has been used for spam blocking, firewall configuration, DNS rewriting, and alerting sys-admins regarding local infections.
