Corey will give an overview of what threat modeling is, and how to use it to highlight security concerns early on in the SDLC. This will lead into a demonstration of using pytm, a Pythonic framework for threat modeling, to identify threats to Jurassic Park’s systems within your favorite Python IDE.

#Pandas is a great library for reading and manipulating data. Chris Malec gave an overview of pandas, focusing on how to read in some common data types, create filters to specific table cells, apply functions to your data, merge tables together, and create nice plots as well as summary tables from your data.
