This session will cover my transition from academic security research at Northeastern’s Seclab into a role of industrial security engineering. We will dive into recent major infrastructure security projects at Block, such as a system to integrate acquisitions into the Block service mesh and bringing security infrastructure features from our Data Center and AWS EKS to AWS Lambda. Through these deep dives we will share how an academic background helps in industrial security engineering.
