#threatmodel

0 posts0 participants0 posts today

Some of my colleagues at #AWS have created an open-source serverless #AI assisted #threatmodel solution. You upload architecture diagrams to it, and it uses Claude Sonnet via Amazon Bedrock to analyze it.

I'm not too impressed with the threats it comes up with. But I am very impressed with the amount of typing it saves. Given nothing more than a picture and about 2 minutes of computation, it spits out a very good list of what is depicted in the diagram and the flows between them. To the extent that the diagram is accurate/well-labeled, this solution seems to do a very good job writing out what is depicted.

I deployed this "Threat Designer" app. Then I took the architecture image from this blog post and dropped that picture into it. The image analysis produced some of the list of things you see attached.

This is a specialized, context-aware kind of OCR. I was impressed at boundaries, flows, and assets pulled from a graphic. Could save a lot of typing time. I was not impressed with the threats it identifies. Having said that, it did identify a handful of things I hadn't thought of before, like EventBridge event injection. But the majority of the threats are low value.

I suspect this app is not cheap to run. So caveat deployor.

i have debilitating #imposterSyndrome 😆 25y experience in #security, but i know for a fact that i am unusually good at facilitating a #threatmodel. you have to get people to trust you enough to tell you things they don't feel great about or would do differently after we meet but that's the thing— together we create remediation plans that let people do their best work & they weave security and privacy into their work and when you meet again you can see how much better things are, it's parade time

Continued thread

it's lucky for some team out there that i find few things are as satisfying as transmogrifying a team of 3 into a team of 9. or 90 into 270.

even i know that's good math! they start spotting problems before they get in front of me for their second and third #threatmodel.
