TL;DR; AI doesn’t break STRIDE. It breaks the idea that systems have fixed roles. Agentic AI systems built on LLMs don’t behave like traditional components. They act like users, services, and data pipelines at the same time, often crossing trust boundaries. MAESTRO provides a layered way to model those risks across modern AI systems. In practice, you’ll end up using both—and treating AI agents lik...
The strongest version of this narrative is its recognition that traditional threat modeling frameworks like STRIDE are insufficient for agentic AI systems, which dynamically cross trust boundaries and assume multiple roles. The introduction of MAESTRO as a layered framework provides a necessary evolution in security thinking, acknowledging that AI systems introduce novel risks—such as memory poisoning, prompt injection, and ecosystem manipulation—that don’t fit neatly into STRIDE’s categories.
