Sandboxing Untrusted Python

- Python lacks built-in safe execution for untrusted code due to its introspective and mutable runtime.
- Attempts to restrict Python's runtime can be bypassed through introspection and exception handling.
- Older sandboxing solutions like sandbox-2 offer OS-level isolation, making Docker or VMs preferable.
- AI/ML's reliance on Python raises security concerns, especially with AI agents executing untrusted code.
- LLMs have architectural flaws, such as prompt injection, leading to security vulnerabilities.
- Isolation strategies include filesystem, network, credential scoping, and runtime isolation.
- Firecracker and Docker provide agent-level isolation, while gVisor is suited for task-level isolation.
- WebAssembly (WASM) offers a promising approach for low-overhead, task-level isolation with explicit permissions.
- Future-proofing AI agent systems requires planning for failure and implementing robust isolation layers.
