KEYNOTE: BSides Knoxville - Why We Break Things… The Neuroscience Of Hackers!
A highlight of my career, I was able to combine the my research in Neuroscience with my experience on the Getting Into Infosec Podcast and present my findings and reflections.
Pacific Hackers: Applying Pareto’s Principle To Securing AWS Organizations
DEF CON 27 Cloud Village
Ayman Elsawah - Using Paretos Principle for Securing AWS with SCPs - DEF CON 27 Cloud Village
Abstract
In this talk I will walk through the use of pareto’s 80/20 rule to add significant security to your AWS accounts at scale with little effort (but lots of testing). We will be leveraging the power of AWS Organizations and Service Control Policies (SCPs) to accomplish our goals. This will be a technical talk and guide on taking advantage of AWS Organizations and SCP from scratch and lessons learned from using it in the wild. If you have not yet utilized AWS Organizations and have (or plan to have) multiple AWS accounts, this talk is for you.
This talk assumes you have secured your individual AWS accounts at the basic level by locking down your root accounts with 2FA, and etc.

Federating AWS IAM Authentication using STS and Shibboleth
- At Pinterest I created an SSO helper tool (in Python) using STS, Shibboleth (yeah I know), that would provide temporary access to engineers.
- No one had anything like this available out there it was beyond it’s time.
- I discovered a bug in their metadata system that made calling STS a problem
