Room: Level 5

Sir Alwyn Williams Building

School of Computing Science, University of Glasgow

18 Lilybank Gardens, Glasgow, G12 8RZ

How to get here

Take the train to Glasgow Queen Street. On arrival, take the right-hand exit from the station (past the ticket office). On leaving the station you should see the entrance to Buchanan Street subway station immediately across the street. Take the subway to Hillhead. On leaving Hillhead station, turn right and walk along Byres Road to Great George Street. Turn right and walk up the hill past the Marks & Spencer, then turn right and walk along Lilybank Gardens. The Sir Alwyn Williams Building is at the far end of Lilybank Gardens, on the left.

Hillhead station is on the left of this campus map, the Sir Alwyn Williams Building is labelled D20.

David Kotz – Saluki: a High-Performance Wi-Fi Sniffing Program

Abstract: Building a campus-wide wireless LAN measurement system faces many efficiency, scalability and security challenges. To address these challenges, we developed a distributed Wi-Fi sniffing program called Saluki. Compared to our previous implementation and to other available sniffing programs, Saluki has the following advantages: (1) its small footprint makes it suitable for a resource-constrained Linux platform, such as those in commercial Wi-Fi access points; (2) the frame-capture rate increased more than three-fold over tcpdump with minimal frame loss; (3) all traffic between this sniffer and the back-end server was secured using 128-bit encryption; and (4) the traffic load on the backbone network was reduced to only 30% of that in our previous implementation. In this paper, we introduce the design and the implementation details of this high-performance sniffing program, along with preliminary evaluation results. – Paper URL

Biography: David Kotz is the Champion International Professor, in the Department of Computer Science, and Associate Dean of the Faculty for the Sciences, at Dartmouth College in Hanover NH. During the 2008-09 academic year he was a Visiting Professor at the Indian Institute of Science, in Bangalore India, and a Fulbright Research Scholar to India. At Dartmouth, he was the Executive Director of the Institute for Security Technology Studies from 2004-07. His research interests include security and privacy, pervasive computing for healthcare, and wireless networks. He has published over 100 refereed journal and conference papers. He is an IEEE Fellow, a Senior Member of the ACM, a member of the USENIX Association, and a member of Phi Beta Kappa. After receiving his A.B. in Computer Science and Physics from Dartmouth in 1986, he completed his Ph.D in Computer Science from Duke University in 1991 and returned to Dartmouth to join the faculty.

Saleem Bhatti – Reducing DNS Caching

Abstract: Traditionally, caching of DNS records has been conservative, using time to live (TTL) values of several hours or days. However, we propose that to support adventurous new capability via DNS, cache times can be reduced to low values, such as 1s or 0s. We present some experimental results to show DNS load with 0s values for TTL and make a request for volunteers to run the same experiment at their own sites!

Omair Uthmani – Risk Analysis for Criminal Context in Information Sharing Policies

Abstract: This presentation outlines of a novel system which maps the information sharing between two domains. It involves the definition of a formalized information sharing policy, which maps the organisation infrastructure which is exposed for the sharing between the domains. A unique element is the additional of a risk context, which is used to define the level of criminal risk involved in the sharing of information. The work shows the results of a survey done within the Scottish Police on the attitudes to criminal risks, and presents a novel system for defining criminal risk which can then be used within the information sharing policy. The work is currently funded by the Scottish Institute for Policing Research (SIPR).

Mat Miehling – Detection Framework for the Reduction of Click-through and ID Theft Fraud in Affiliate Marketing

Abstract: This presentation will focus on outlining criminal activity within affiliate marketing related to click-through and ID theft crime, based on real-life crime data. It shows the mechanisms that criminals might use in order to act fraudulently, and presents a framework that has been created in order to detect whether there is a risk from malicious affiliates. The work is funded by the FSA (Financial Services Authority), and aim to overcome some of the risks related to online fraud.
