The Agentic Fundamentals module has taken you through everything you need to know to reframe your mindset to secure agentic technology: the fundamentals of how the technology works, how we go about threat modelling such an advanced and unpredictable technology, and how we monitor it. From this module, Agent Hijacking, onwards, we will take a more in-depth look at each of the Top 10 vulnerabilities for Agentic Applications. Starting, naturally, with ASI01: Agent Goal Hijack. Let's go in depth and get hands-on!
