September 14th, 2012

A couple students in my research group and I did a bunch of analysis of the Twitter response to the iPhone 5 announcement this past Wednesday (Sept. 12). We put all our findings into a snazzy infographic. Check it out!

Social engineering

October 27th, 2011

In class we’ve talked about how social engineering is a fundamental part of hacking into systems. Here are two fantastic stories about how a security consultant has robbed more than 1,000 banks in order to prove to his clients that security means more than using good passwords (article 1, article 2). They are excellent reads!

Midterm News

October 21st, 2011

The midterm from Wednesday is now online. For those of you who were not in class today, we went over the midterm. Everyone has the opportunity to rework (and resubmit) problems they didn’t get full credit on for additional points (you will receive half the full points for each problem you lost points on on the original midterm). This is in everyone’s interest to do, so please take advantage of it – work your results out on a separate sheet of paper and submit your reworked problems attached to your original midterm on Monday.

If you weren’t in class today, please contact me to find a time when you can stop by and pick your midterm up.
