I am super-excited to announce that my new book, Threat Modeling: Designing for Security (Wiley, 2014) is now available wherever fine books are sold!
The official description:
If you’re a software developer, systems manager, or security professional, this book will show you how to use threat modeling in the security development lifecycle and the overall software and systems design processes. Author and security expert Adam Shostack puts his considerable expertise to work in this book that, unlike any other, details the process of building improved security into the design of software, computer services, and systems — from the very beginning.
- Find and fix security issues before they hurt you or your customers
- Learn to use practical and actionable tools, techniques, and approaches for software developers, IT professionals, and security enthusiasts
- Explore the nuances of software-centric threat modeling and discover its application to software and systems during the build phase and beyond
- Apply threat modeling to improve security when managing complex systems (or even simple ones!)
- Manage potential threats using a structured, methodical framework
- Discover and discern evolving security threats
- Use specific, actionable advice regardless of software type, operating system, or program approaches and techniques validated and proven to be effective at Microsoft and other top IT companies
Threat Modeling: Designing for Security is full of actionable, tested advice for software developers, systems architects and managers, and security professionals. From the very first chapter, it teaches the reader how to threat model. That is, how to use models to predict and prevent problems, even before you’ve started coding.
Threat Modeling: Designing for Security is jargon-free, accessible, and provides proven frameworks that are designed to integrate into real projects that need to ship on tight schedules.
For more information, I’ve set up a small book website: threatmodelingbook.com.
Amazon has Kindle edition, and is saying that the paperback will ship in “9-11 days.” I believe that’s startup issues in getting the books to and through the warehousing system, but don’t know details. I will be having a book signing at RSA, Wednesday at 11 AM in Moscone South. (iCal reminder.)
In light of me already spending time on what to put on which blog, but more importantly, not wanting readers to have to subscribe to three blogs, I’ll be blogging about threat modeling here on New School.

Yesterday, I announced that I’ve set up a mailing list. You may have noticed an unusual feature to the announcement: a public commitment to it being low volume, with a defined penalty ($1,000 to charity) for each time I break the rule.
You might even be wondering why I did that.
In the New School, we study people, and their motivations. Knowing that introspection is a fine place to start, a poor place to end and an excellent source of mis-direction, I talked to several people who seem like the sort I want on my list about their experience with mail lists.
The first thing I heard was fairly unanimous: people don’t subscribe because they get spammed.
The perception is that many people who create lists like this abuse those lists. So to address that, I’m using a commitment device: a promise, made publicly in advance. By making that promise, I give myself a reason to hold back from over-mailing, and I give myself a way to constrain helping others with my list. (But not eliminate such help — perhaps that’s a bad idea, and it should be just about those new things where I’m a creator. Would love your thoughts.)
The second issue I heard is that unsubscribing tends to feel like an interpersonal statement, rather than a technical one (such as “I get too much email.) So I promise not to be offended if you unsubscribe, and I promise to be grateful if you tell me why you unsubscribe. This is why I love Twitter: I control who I listen to. It’s also why I think the “unfollow
unsubscribe bug” (real or imagined) was such a good thing. It provided a socially acceptable excuse for unfollows.
Are there other factors that hold you back from signing up for a mailing list like mine? Please let me know what they are, I’d love to address them if I can.

I’d like to nominate Xfinity’s “walled garden” for the worst user experience in computer security.
For those not familiar, Xfinity has a “feature” called “Constant Guard” in which they monitor your internet for (I believe) DNS and IP connections for known botnet command and control services. When they think you have a bot, you see warnings, which are inserted into your web browsing via a MITM attack.
Recently, I was visiting family, and there was, shock of all shocks, an infected machine. So I pulled out my handy-dandy FixMeStick*, and let it do its thing. It found and removed a pile of cruft. And then I went to browse the web, and still saw the warnings that the computer was infected. This is the very definition of a wicked environment, one in which feedback makes it hard to understand what’s happening. (A concept that Jay Jacobs has explicitly tied to infosec.)
So I manually removed Java, and spent time reading the long list of programs that start at boot (via Autoruns, which Xfinity links to if you can find the link), re-installed Firefox, and did a stack of other cleaning work. (Friends at browser makers: it would be nice if there was a way to forcibly remove plugins, rather than just disable them).
As someone who’s spent a great deal of time understanding malware propagation methods, I was unable to decide if my work was effective. I was unable to determine the state of the machine, because I was getting contradictory signals.
My family (including someone who’d been a professional Windows systems administrator) had spent a lot of time trying to clean that machine and get it out of the walled garden. The tools Xfinity provided did not work. They did not clean the malware from the system. Worse, the feedback Xfinity themselves provided was unclear and ambiguous (in particular, the malware in question was never named, nor was the date of the last observation available). There was no way to ask for a new scan of the machine. That may make some narrow technical sense, given the nature of how they’re doing detection, but that does not matter. The issue here is that a person of normal skill cannot follow their advice and clean the machine. Even a person with some skill may be unable to see if their work is effective. (I spent a good hour reading through what runs at startup via Autoruns).
I understand the goals of these walled garden programs. But the folks running them need to invest in talking to the people in the gardens, and understand why they’re not getting out. There’s good reasons for those failures, and we need to study the failures and address those reasons.
Until then, I’m interested in hearing if there’s a worse user experience in computer security than being told your recently cleaned machine is still dirty.
* Disclaimer: FixMeStick was founded by friends who I met at Zero-Knowledge Systems, and I think that they refunded my order. So I may be biased.

I’m on the program committee this year, and am looking forward to great submissions.

Rich Mogul over at Securosis (N.B. I’m a contributing analyst there) has a great post on how, due to human error, some of his AWS credentials got nabbed by some miscreants and abused. We here at the New School love it when folks share how they were compromised and what they did about it. It is this sort of transparency that helps us all. Kudos to Rich for being willing to share his pain for our benefit.

At Light Blue Touchpaper, Ross Anderson says “We have a vacancy for a postdoc to work on the psychology of cybercrime and deception for two years from October.”
I think this role has all sorts of fascinating potential, and wanted to help get the word out in my own small way.

Remarkably, some software that people host on your behalf, where you have no contract or just a contract of adhesion, can change at any time.
This isn’t surprising to those who study economics, as all good New School readers try to do. However, this is a reminder/request that when you move, please resubscribe to New School. We have some interesting announcements forthcoming, and will try to get more interesting content up soon.

The next Workshop on the Economics of Information Security will be held June 11-12 at Georgetown University, Washington, D.C. Many of the papers look fascinating, including “On the Viability of Using Liability to Incentivise Internet Security”, “A Behavioral Investigation of the FlipIt Game”, and “Are They Actually Any Different? Comparing 3,422 Financial Institutions’ Privacy Practices.”
Not to mention “How Bad Is It? – A Branching Activity Model to Estimate the Impact of Information Security Breaches” previously discussed here.
