Hands-on threat modeling

Sebastien Deleersnyder
Thursday June 16, 09:00 - 17:00

This is a Threat Modeling course for DevOps Engineers to improve reliability and security of delivered software. We will teach an iterative and incremental threat modeling method.

You will perform threat modeling in 4 sprints. Exercises are built upon a fictional system, migrating a legacy system towards a cloud application:

  • Modeling a hotel booking web and mobile application, sharing a REST backend
  • Threat identification as part of migrating the system to AWS
  • AWS threat mitigations for the booking system build on microservices
  • Building an attack library for CI/CD pipelines

  • Threat modeling introduction
  • Diagramming
  • Identifying threats
  • Addressing threats
  • Practical threat modeling
  • Threat modeling resources
Learning goal
