- Measuring the Impact of DMARC's Part in Preventing Business Email Compromise
- This paper (done in partnership with Jay Jacobs and Wade Baker) Since 2016, the Global Cyber Alliance (GCA) has been working to accelerate adoption of DMARC, an email security standard, by providing tools and resources to aid implementation. This paper measures the economic benefit from that activity. In less than two years, GCA’s DMARC initiative has resulted in more than 5,700 organizations across more than 180 countries adopting DMARC. This has lead to significant financial benefits across a diverse array of industries and governments. The full report is at the GCA website.
- Threat Modeling in 2018: Attacks, Impacts and Other Updates
- My Blackhat 2018 talk is about how attacks always get better, and that means your threat modeling needs to evolve. This talk looks at what's new and important in threat modeling, organizes it into a simple conceptual framework, and makes it actionable. This includes new properties of systems being attacked, new attack techniques (like biometrics confused by LEDs) and a growing importance of threats to and/or through social media platforms and features. Take home ways to ensure your security engineering and threat modeling practices are up-to-date. (The slides are available as a PDF or online viewer.)
- That Was Close! Reward Reporting of Cybersecurity 'Near Misses'
- From the abstract: "While information regarding the causes of major breaches may become public after the fact, what is lacking is an aggregated data set, which could be analyzed for research purposes. This research could then provide clues as to trends in both attacks and avoidable mistakes made on the part of operators, among other valuable data... An alternative is a voluntary reporting scheme, modeled on the Aviation Safety Reporting System housed within NASA, and possibly combined with an incentive scheme. Under it, organizations that were the victims of hacks or “near misses” would report the incident, providing important details, to some neutral party. This database could then be used both by researchers and by industry as a whole. People could learn what does work, what does not work, and where the weak spots are.

- Engineers are People Too
- Keynote at SOUPS 2010 . In Engineers Are People Too Adam Shostack will address an often invisible link in the chain between research on usable security and privacy and delivering that usability: the engineer. All too often, engineers are assumed to have infinite time and skills for usability testing and iteration. They have time to read papers, adapt research ideas to the specifics of their product, and still ship cool new features. This talk will bring together lessons from enabling Microsoft's thousands of engineers to threat modeling effectively, share some new approaches to engineering security usability, and propose new directions for research.
- The Crisis In Information Security
- This is a high level and very well reviewed talk that I'm giving discussing some of the lessons from the New School. I've also been speaking on threat modeling. The slides are designed to support the talk, rather than stand on their own.
- The New School of Information Security (book)
- Adam Shostack and Andrew Stewart. We examine some of the ongoing shortcomings of the information security profession, and propose some very practical steps that any individual or organization can take to improve things. Available from fine booksellers now.
- Older writing on Threat Modeling
At a Security Modeling workshop, I presented Experiences Threat Modeling at Microsoft, a title which is pretty self explanatory. (Slightly updated from the workshop version.)
In MSDN magazine, Uncover Security Design Flaws Using The STRIDE Approach and Reinvigorate your Threat Modeling Process are about how I'm thinking about threat modeling and some lessons learned. MSDN also published Getting Started With The SDL Threat Modeling Tool.
A series of blog posts on lessons learned threat modeling at Microsoft. The series can be downloaded as a Word doc, The Trouble with Threat Modeling.
As mentioned above, Elevation of Privilege: the Threat Modeling Game is the easy way to get started threat modeling. You can download a copy from Github, and there's a blog post with the announcement. My Black Hat 2010 talk The easy way to get started threat modeling covers some of why the game works, as does a longer paper, Elevation of Privilege: Drawing Developers into Threat Modeling (PDF).

A philosophical digression on the relationship of liberty and security
"The freedom which we enjoy in our democratic government extends also to our ordinary life. We throw open our city to the world, and never by alien acts exclude foreigners from any opportunity of learning or observing although the eyes of an enemy may occasionally profit by our liberality. We live exactly as we please and yet are just as ready to encounter every legitimate danger. If with habits not of labor but of ease, and courage not of art but of nature, we are still willing to encounter anger, we have the double advantage of not suffering hardships before we need to, and of facing them in the hour of need as fearlessly as those who are never free from them. The price of courage will surely be awarded most justly to those who best know the difference between hardship and pleasure and yet are never tempted to shrink from danger. And it is only democratic people who, fearless of consequences, confer their benefits not from calculations of expediency but in the confidence of liberality.From The Funeral Oration by Pericles of Athens, 431 B.C.
