MAESTRO Threat Modeling
Replace a generic security review with an agent-aware one that lists the attack types specific to agents and pairs each with a concrete defence before you ship.
Description
Run an agent-specific security review before you ship, using the MAESTRO categories. They are: risks from the model itself, threats to the data, attacks from inside and outside the system, and red-team probing. This takes classic threat modeling, such as STRIDE and LINDDUN, and adapts it to how agents get attacked. That includes prompt injection, memory poisoning, tool misuse, data theft, and agent-on-agent attacks. The output is a list of threats, each one tied to a concrete defence.
When to apply
Run this before any agent goes to production, above all when it has tool access, a free-running loop, multi-agent coordination, or sensitive data. Run it again after every real change in capability. Do not use it instead of normal application security. MAESTRO adds to AppSec, it does not replace it. Don't apply it when the system really is a single-turn chat with no tools, no memory, and no access to private data. There is no agent attack surface to model.
What it involves
- Enumerate foundation-model threats
- Enumerate data-protection threats
- Enumerate internal threats
- Enumerate external threat vectors
- Map defensive controls to each threat
- Red-team the agent against the catalogue
