To build a reusable security model, use this Skill to define entities, trust relationships, and invariants for your target system. These durable models can then be saved and loaded to guide future research sessions.

Yes, you can create security models for diverse targets including source, web, cloud, binary, supply-chain, Android, Apple, and Microsoft systems. The modeling constructs support this wide range of environments.

You need a MaxTAC environment with Python installed, along with the workspace_db and corpus_helper libraries. You must also define a workspace root, model ID, target, and summary to initialize.

Start a new security model by running the model.py init script with arguments for your workspace root, model ID, target, subsystem kind, and a summary. This creates the foundational structure for your research.

Invariant receipts help capture and maintain durable security models by recording specific conditions that must remain true across sessions. This ensures consistency and avoids redundant work during complex system analysis.

Model reuse depends on the stability of your defined entities, relations, and invariants. If the target system architecture changes significantly, you must update the security model constructs to maintain accurate research analysis.
