Microsoft SQL Security Across the MAESTRO Stack: Building Secure Agentic AI with Defense-in-Depth

A deep dive into securing agentic AI architectures using Microsoft SQL mapped against the MAESTRO threat modeling framework. Covers how SQL Server's built-in capabilities — including Always Encrypted, Row-Level Security, SQL Ledger, vector search, audit logging, and least-privilege execution — address each MAESTRO layer (Foundation Models, Data Operations, Agent Frameworks, Deployment, Observability, Compliance, Agent Ecosystem). Argues that Microsoft SQL can serve as a governed execution boundary for enterprise AI systems rather than just a data store, enabling defense-in-depth across the full AI operational stack.
