Serving on Computers & Security Editorial Board

COSEAs of January 2014, I’m serving on the editorial board of Elsevier’s Computers & Security journal. Apparently, it is the official journal of Technical Committee 11 (computer security) of the International Federation for Information Processing (IFIP). The journal is in its 29th year, which makes it one of the oldest archival publications in the field of computer security. One of the main goals of the editorial board nowadays is to arrange quality reviews with quick turn-around.

 

Final Report on Internet Voting

final reportAfter about 18 months of work, the Internet Voting Panel I served on has released its final report on February 12 and
submitted it to the Legislative Assembly of British Columbia. The report contains the panel’s conclusions and recommendations, and summarizes the benefits and challenges of implementing Internet voting for provincial or local government elections in B.C. On October 23, 2013 the panel published a Preliminary Report for a six-week public comment period, ending on December 4, 2013.  The panel reviewed the commentary, including additional submissions from experts, academics and vendors in the Internet voting community. The report can be found on the panel’s web site.

What research do I really do?

My department has made a short introductory video-clip about my research group LERSSE. For those who won’t read papers but still want to get an idea about what kind of research my graduate students do, just sit back and enjoy this 3-minute long summary.

Popular press continues to discuss research of my graduate students on Social BotNets. The most recent article (by Eagle Gamma) appeared in Infoworld in early April. Unlike earlier coverage, it discusses more recent work (Design and Analysis of a Social Botnet), in which an economic analysis of Social Botnet feasability and challenges for throttling them is discussed.

Project Presentations at Graduate Course in Security

Students in my graduate course on computer security are presenting their term papers on April 10. The topics vary from evaluation of Sybil detection mechanisms to detection of DDoS attacks on grid clusters. This mini-conference is open to public.

The Impact of Password Meters on Password Selection

Password meters tell users whether their passwords are “weak” or “strong.” In this paper, we report on a laboratory experiment to examine whether these meters influenced users’ password selections when they were forced to change their real passwords, and when they were not told that their passwords were the subject of a study. We observed that the presence of meters yielded significantly stronger passwords. We then performed a followup field experiment to test a different scenario: creating a password for an unimportant account. In this scenario, we found that the meters made no observable difference: participants simply reused weak passwords that they used to protect similar low-risk accounts. We conclude that meters result in stronger passwords when users are forced to change existing passwords on “important” accounts and that individual meter design decisions likely have a marginal impact.

More details are in the paper, which will be presented at CHI ’13 held April 27-May 3.

Teaching Security and Privacy in Online Social Networks

This term, I’m teaching a graduate seminar-based course on security and privacy in online social networks. Students in the course are reading, presenting, critiquing, and discussing most significant and most recent papers from top venues on the subject. They also do a project related to security and write a term paper based on it. More information about can be found at the course web site.
