NSPW 2009 Papers Online

[See only posts in English]

Just a quick note: The final papers for the New Security Paradigms Workshop 2009 are now online, including my own (also here). Two of them got their share of public attention already, Maritza Johnson’s Laissez-faire file sharing (in Bruce Schneier’s blog) and Cormac Herley’s So Long, And No Thanks for the Externalities: The Rational Rejection of Security Advice by Users (Schneier’s blog; New School of Information TechnologyHeise.de). For those of you who can afford the trip, the authors will present these two papers again in a session at ACSAC, December 7-11.

Swiss Cheese Security

I’m off for the New Security Paradigms Workshop in Oxford, where I will present what I currently call the Swiss Cheese security policy model. My idea is to model security mechanisms as classifiers, and security problems in a separate world model as classification problems. In such a model we can (hopefully) analyze how well a mechanism or a combination of mechanisms solves the actual problem. NSPW is my first test-driving of the general idea. If it survives the workshop I’m going to work out the details. My paper isn’t available yet; final versions of NSPW papers are to be submitted a few weeks after the workshop.
