Training: Advanced Whiteboard Hacking – aka Hands-on Threat Modeling

This updated Black Hat edition training offers hands-on threat modeling exercises based on real-world projects, to equip participants with skills as Threat Modeling Practitioners. The course integrates exercises using MITRE ATT&CK, Agile and DevOps practices, and includes a challenge on threat modeling a Machine Learning-Powered Chatbot. Participants will engage in CTF-style challenges, battling for control over an offshore wind turbine park, in a threat modeling war game.

For beginner to intermediate learners, the training includes a two-hour introductory self-paced module. Exercises focus on practical use cases with detailed environments, questions, and templates. Students, in teams of 3-4, will do challenges: - Diagramming techniques for a travel booking service - Threat modeling cloud-based update services for IoT kiosks - Developing attack trees against a nuclear research facility - Using MITRE ATT&CK for SOC Risk-Based Alerting systems - Mitigating threats in payment services with microservices and S3 buckets - Applying the OWASP Threat Modeling Playbook in agile development - Securing CI/CD pipelines

Each exercise concludes with group discussions and documented solutions. Participants receive the Threat Modeling Playbook, a year of online learning platform access, and will get feedback and guidance on an after-training assignment.
