Earlier this year, I helped to organize a workshop at Schloss Dagstuhl on Empirical Evaluation of Secure Development Processes. I think the workshop was a tremendous success, we’ve already seen publications inspired by it, such as Moving Fast and Breaking Things: How to stop crashing more than twice, and I know there’s more forthcoming. I’m…

I’m happy to say that some new research by Jay Jacobs, Wade Baker, and myself is now available, thanks to the Global Cyber Alliance. They asked us to look at the value of DNS security, such as when your DNS provider uses threat intel to block malicious sites. It’s surprising how effective it is for…

There’s a fascinating paper, “Tuning Out Security Warnings: A Longitudinal Examination Of Habituation Through Fmri, Eye Tracking, And Field Experiments.” (It came out about a year ago.) The researchers examined what happens in people’s brains when they look at warnings, and they found that: Research in the fields of information systems and human-computer interaction has…

Then he explained the name was important for inspiring the necessary fear. You see, no one would surrender to the Dread Pirate Westley. The DREAD approach was created early in the security pushes at Microsoft as a way to prioritize issues. It’s not a very good way, you see no one would surrender to the…

Today is John Harrison’s 352nd birthday, and Google has a doodle to celebrate. Harrison was rescued from historical obscurity by Dava Sobel’s excellent book Longitude, which documented Harrison’s struggle to first build and then demonstrate the superiority of his clocks to the mathematical and astronomical solutions heralded by leading scientists of the day. Their methods…

There’s a new paper from Mark Thompson and Hassan Takabi of the University of North Texas. The title captures the question: Effectiveness Of Using Card Games To Teach Threat Modeling For Secure Web Application Developments Gamification of classroom assignments and online tools has grown significantly in recent years. There have been a number of card…
