## AI overview

This article explains how to build zero-trust AI agents with Google's Agent Development Kit (ADK). It presents an autonomous customer support and returns agent as an example and recommends hard infrastructure-level controls: cryptographic signatures for database writes, kernel-level sandboxing with gVisor for dynamic code execution, and deterministic gateways for validating I/O, business logic, and data leakage. These controls address prompt injection, unauthorized state changes, credential leakage, and host compromise.

## Source excerpt

Building autonomous AI agents that mutate production state requires moving beyond soft system prompts to a robust zero-trust architecture. To secure Google Agent Development Kit (ADK) workflows against prompt injections and malicious execution, developers must implement hardware-backed cryptographic signatures for database writes, kernel-level sandboxing with gVisor for dynamic code, and deterministic semantic gateways for I/O validation. By enforcing these hard security boundaries at the infrastructure level, you can safely deploy multi-tool AI agents without risking unauthorized data manipulation or server compromise.
