The Elevation of Privilege game has had way more staying power than I would have expected. But the online experience in this time of global pandemic has left out some of the magic that made it work. So I was really skeptical when Simon Gibbs from Agile Stationery mailed me about an approach to playing…

So Chris Romeo has a blog post, “Threat modeling: better caught than taught.” In it, he advocates for threat modeling being a skill passed on informally. And, like many things in threat modeling, that’s attractive, sounds fun, and is utterly wrong. Let’s threat model this: What are we working on? Scaling threat modeling across all…

Contextualisation of Data Flow Diagrams for security analysis is a new paper to which I contributed: “Abstract: Data flow diagrams (DFDs) are popular for sketching systems for subsequent threat modelling. Their limited semantics make reasoning about them difficult, but enriching them endangers their simplicity and subsequent ease of take up. We present an approach for…

Practicing physical distancing has already dramatically changed how we work, and will continue to do so. Being physically distant means we can’t use a whiteboard to help us talk through “what are we working on?” There are technical facets of threat modeling, like using visual models to show and scope “what are we working on?”…

This post comes from a conversation I had on Linkedin with Clint Gibler. He wrote: One challenge I’ve heard from a number of companies is that, with say 3-5 AppSec engineers supporting 500 – 1000 devs, you can’t TM every story, or even every epic. So what do you focus on? The high risk /…

This is useful in and of itself, and is also the sort of thing that more standards bodies should do, by default. It’s all too common to have a new standard come out without…

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…

Quick: are all the flowers the same species? People regularly ask me to promote their threat modeling work, and I’m often happy to do so, even when I have questions about it. There are a few things I look at before I do, and I want to share some of those because I want to…

The White Box, and its accompanying book, “The White Box Essays” are a FANTASTIC resource, and I wish I’d had them available to me as I designed Elevation of Privilege and helped with Control-Alt-Hack. The book is for people who want to make games, and it does a lovely job of teaching you how, including…
Read More The White Box Essays (Book Review)It’s well known that adoption rates for multi-factor authentication are poor. For example, “Over 90 percent of Gmail users still don’t use two-factor authentication.” Someone was mentioning to me that there are bonuses in games. You get access to special rooms in Star Wars Old Republic. There’s a special emote in Fortnite. (Above) How well…
