Over the last several months, Jim Hogan and I have been kicking around ideas with regard to the issue of security in the Internet of Things (IoT). This all began with an off-hand comment I made at a Hogan panel at DAC. The idea is that some non-traditional approaches to security at the system-level -- particularly based on biological analogies -- should become relevant. This topic surfaces from time to time (there was even a blog about it last year in EETimes), but rarely seems to go very deep. We thought it was time to drop down a level and to delve into why this should be relevant to the IoT and how the mechanics might work. We hope you find it interesting. Alternative security strategies Security techniques in the Internet have largely drawn inspiration from physical security -- keys, firewalls, trusted zones, and more. However, there are other possible sources of inspiration, biology being an obvious example. We routinely talk of viruses, but that analogy extends only to the concept of a malicious attacker and the spread of infection, not so much to methods of defense. This is unfortunate, because the ability of living organisms to defend against infection … Continue reading →

Oct 13, 2014 by Matt Shipman A new paper examines security risks and policy questions related to the growing field of synthetic biology. While the author doesn't think the field is ripe for exploitation by terrorists, it does highlight significant gaps in our understanding of the nuts and bolts of lab work in synthetic biology that can contribute to security risks. "The driving question here is whether terrorists can easily draw on published synthetic biology research to develop new bioweapons," says the paper's author, Kathleen Vogel, a biochemist/social scientist at NC State who focuses on biosecurity issues. "The policy community is engaged in a long-running debate on how and whether synthetic biology should be governed or regulated to protect public well-being without stifling science and innovation." Synthetic biology involves the design of new biological components, devices or systems that don't exist in nature, or the redesign of existing natural biological systems. Synthetic biology aims to make biological systems work more efficiently or to design biological tools for specific applications such as developing more effective antibiotics. To address the security question, Vogel looked at how easily synthetic biology results could be replicated. Specifically, she looked at how technological advances diffuse and … Continue reading →

Ive written before about how mathematics can be used to unify lots and lots of different disciplines. Well, heres another great example from an article (behind paywall) from 2007. Its about how Stephen Oh, the co-founder of AccuScore, brought his knowledge of population genetics to sports: So in 2002, Oh began writing code that simulated football teams instead of human genomes. Genes were replaced with players; mutation rate and selection pressure became the probability that a pass would be completed or that a player would run for a touchdown. Each generation became a discrete play in a game. The rules of American football, in which each play depends cleanly on the ones before it, lent themselves to modelling the game this way. And so the idea behind Accuscore was born. I love this kind of thing. Read more from the original source: Quantitative Biology and Quantitative Football … Continue reading →

TIME Health Research Those Pesky House Flies May Actually Improve Our Health Getty Images According to new research in 'Genome Biology' The house fly is a rarely celebrated insect, but new research published Tuesday finally provides the pest with some positive recognition. The house fly (Musca domestica) has a genome that could actually give scientists insight into pathogen immunity, helping humans live healthier lives, researchers write in the journal Genome Biology. And its all because of their, well, gross-factor. Since the house fly lives on animal and human waste, according to Science Daily, [t]hey are an important species for scientific study because of their roles as waste decomposers and as carriers of over 100 human diseases, including typhoid, tuberculosis and worms. Their immunity system genes can be studied to help humans be healthier in toxic and disease causing environments, the researchers add, and detoxification genes could help scientists find better ways to manage toxic environments.
