Questions on threat modelling

1)How to Integrate threat modelling into jira work flows?2)How/where to store the threat models so that can be easily be reviewed for future reference?In my experience diagrams/pdfs become obsolete and no one views them in the future?3)How to ensure all threats are covered ? How to know that we have threat modelled enough?4)How is threat modelling  different from a secure design review ?

I'm Izar Tarandach - and if you have questions, I may have answers!Q&A

Hi everyone, I’m Izar Tarandach, a Sr Staff Engineer at Datadog these days helping develop security products. Previously, I helped Squarespace, Autodesk, DellEMC RSA, IBM, and Bridgewater Associates design and implement product- and enterprise-wide security solutions, offering guidance in the design and implementation of secure systems and products.I’m also a co-author of "Threat Modeling: A Practical Guide for Development Teams", O'Reilly with Matthew Coles, and part of the "Threat Modeling Manifesto" band. I wrote the Continuous Threat Modeling Handbook and lead the OWASP pytm project, the first (I think!) threat-model-with-code framework out there.Currently I am looking into the bridge between Observability and Security. I’m excited to talk about that, secure development and engineering, threat modeling, careers in cybersecurity, Threat Modeling Manifesto, my favorite movies, dogs, what is that funny fish and anything in between.How it works: Add your questions below any time before

NPS for threat modeling

Hello everyone!I am searching for ideas or experiment feedback on how to gather a sort of TM “NPS score” as a measure on how well or not we’re doing with our engineering teams. Hint: Sending MS Forms surveys don’t really work.Looking past the “number of threat models performed”, “number of security work items opened” (and maybe never worked on), etc… how would you measure the actual value that is brought (or not) to various engineering teams as you educate/have them perform threat modeling?As I am endeavoring in some development work to create a custom Azure DevOps extension for NFRs to bring stuff in-band of engineering teams (and ensure something more cyclic too), I have some rough ideas, but would like to open the question to the experts :)Thanks!

NIST Maturity mover using Threat Modeling

My organization is working to move our NIST maturity and one of the ways my team can help is in the area of Threat Modeling. There are some specific questions around TM but it seems that NIST looks at Networking, Database and Application Threat Modeling separately.  To be honest, I didn’t know modeling was done in different pillars but holistically.Here are a few of the NIST questions.  I would love feedback on how I can use a tool like IriusRisk to move the needle on these.Which of the following describe how network threat modeling is performed by the organization? TM performed against network attack surfaces Against data flow What is the estimated % of all databases for which the organization performs threat modeling to identify and prioritize potential threats? Which of the following describe the organization's implementation of threat modeling #3 is focused on application TM incorporated in SDLCBTW - NIST defines SDLC as System Development Lifecycle

Anyone tried to apply "Collaborative modeling" ideas in your threat modelling?

https://freecontent.manning.com/better-software-development-with-collaborative-modeling/ - I’ve come across this book and the ideas look very applicable to what we do with threat modelling.Anyone familiar with these ideas? Have you tried it? Any other thoughts?

Question on reddit: Threat Modeling sometimes not the best option for adressing security? Request for comments

Sharing this from a post by u/RoAmbk on r/threatmodeling, I thought it would be good to get this community’s input.Hi,I sometimes need to help projects in the web/cloud domain, some of them are green field projects. Threat modeling is a vital part of the SSDLC of these projects. On the other hand, there are guidelines like OWASP Top 10, OWASP ASVS, and many more that can help getting to a certain security level.I prefer to first follow guidelines and only after these have been assessed, perform threat modeling to detect risks and mitigate them.I had the experience that putting threat modeling before assessing a guideline is not as effective for these kind of projects.On the other hand, threat modeling is best when assessing a very custom solution like an embedded system with networked and legacy components.Do you have some thoughts and comments? I would be very interested in your opinion.Thank you What do you think? (source: https://www.reddit.com/r/threatmodeling/comments/10xaxsm/thre

What makes trust boundaries a challenging concept?

I routinely hear people struggle. Perhaps it's been too long since I first encountered it. Have you heard a good explanation of why it's hard? Do you have one of your own? What helped you overcome it? How do you teach it, or elicit boundaries when you’re leading threat modeling work?

threat model tool - threatware

This community seems like an appropriate place to share approaches to threat modelling, so I thought I’d share an open source tool called threatware that I created to help validate and manage threat models.  I wrote a longer blog post discussing the origin of it, but this community might find some of the design decisions I made when I created the (suggested) process and tool - see An Opinionated Approach - as relevant discussion topics for challenges we all face when operating a threat modelling program of work.Hope you find it interesting, maybe even useful.  Happy to discuss.

Has anyone experienced with integrating TM in automated pipelines?

It seems to me that with the growing number of tools supporting threat modeling or working with TMs in an automated fashion (IR,shiftleft,OTM) a lot of possibilities open up for integrating these in CI/CD or other workflows.Are you aware of any implemented use cases in this direction? Are there any working examples for generating a TM (even for a small well understood domain) based on code or config changes for instance?

Threat Models in SBOMs

SBOMs are a critical part to helping secure the software supply chain.  Having a catalogue of libraries and components in an SBOM is obviously the key element of this, so that it can be queried by security tools to identify known vulnerabilities.  So far so good. I can’t help thinking that including a threat model in the SBOM would help to provide some additional context about the security decisions made by the vendor.  What I mean is that as a software vendor, I choose my third party components and include them in my software.  When I do that, I may make some security decisions such as including a library with a known vulnerability because I know that we don’t use that library in a way that exposes the vulnerability.  A threat model would be a way for me to communicate this to readers of my SBOM.What do the SBOMmers think of this?  Has any work been done in the area of marrying threat modeling and SBOMs?

Threat modeling: mandatory or nah?

I came across an article that I can’t seem to find again. It asked if threat modeling should be a mandatory practice. We might all want to agree that it should (as we are a threat modeling community). However, I don’t believe the answer is binary. I think there is a spectrum that the answer lies on, and every organization has its point on that spectrum that they will be at that will evolve at some rate.I’d love to discuss everyone’s thoughts on this subject. Maybe a specific practice worked at one place but didn’t work at another. Also, something I think is interesting. Does trending threat modeling toward being mandatory help define a mature threat modeling process?

How do you define the success criteria for threat modeling?

How do you determine the “success” of a threat model program? Is there any Key Performance Indicators you’re using?It is not just the # of threat models created or # of threats reported, but the impact it makes. I’m curious how the community measures the impact of a threat model?

What's your favorite Threat Modeling methodology?

Since there are many different threat modeling methodologies (STRIDE, PASTA, DREAD, etc), I’d like to ask the community members:Which methodology is your favorite, and why? I’ve only used STRIDE and I’m eager to hear everyone’s thoughts on the others.

What can threat modeling teach us about threat modeling? 🤪

The 4-question philosophy is of course a useful and proven tool for guiding the threat model, but perhaps those 4 questions can too be useful for guiding a successful threat modeling program.  Having spoken to so many different practitioners of threat modeling, it’s clear that there’s variances in schools of thought, processes that work for one organization versus another, motivations, and challenges that different teams/orgs encounter. I’d love to hear from the community your wisdom surrounding: What were you trying to build (who owned the activity, etc.)? What can go wrong (analysis paralysis, etc.)? What did you do about it? Finally…how did you evaluate if you did a good job?  Threat modeling is all about collaboration, so I’m curious what the community can share based on their experience

Threat modelling program and practice maturity dilemma

There are a few maturity models out there that one could apply to threat modelling however none that fit the mold. i am in search for a maturity model/framework to leverage as a yard stick to measure progress in threat modelling practice and threat modelling program. I wanted to seek expertise, advice and guidance from the community as to what folks are using or have used as a maturity framework that seem to work.

Example Software Supply Chain Threat Model

I’m reposting my friend, François Proulx’s supply chain analysis because I believe it to provide an excellent example of a thorough threat model. Yes, indeed, do read the post if you need to understand software supply security. But this analysis also demonstrates a couple of critical threat modelling methods:Cataloging the relevant attacks (often called a “threat library”) Analyzing how the attacks work, who the victim is, what the likely impact will be if compromised Identifying appropriate counter-measures, which may include defences, mitigations, monitoring, etc. Explaining in some detail how the analysis worksA #threat model isn’t its methods. I often hear people confuse method with model. There isn’t any STRIDE analysis (though this model makes effective use of attack trees). There’s only a single visual representation that might be called a data flow diagram (DFD) - and that is very loose. it’s more of a process flow. Neither of these are required to build a model (though they mi

How to start a Security Champions Program?

Hi folks!  I hear the term security champions being thrown around quite often and how important it is for some to start building the program. I’ve seen different companies approach the topic very differently with some succeeding and some outright failures. Some have started with initiatives to train their entire development organization to understand security a little better before heading down this path. Some have asked for volunteers and incentivize them to help be part of the team and help build the process. Others may go ahead and just select individuals themselves and “volunteer” them to be the bridge for the teams. My question for you all is, what has your experience been like? Is there a method that works better than others? What are some great ways to start this discussion with various teams and how do we get them more engaged? Where should a company start when thinking of building a Security Champions program? Are the any specifics that need to be considered before starting th
