## Blog posts

- [Architecting Trust: An Executive's Field Guide to AI Security](https://aragrow.me/blog/architecting-trust-course/): Eight short parts that turn AI security from a black box into decisions you can own. Learn to ask the right questions of any tool or vendor, and tell a real answer from a hand-wave. Built for the person who signs off, not the person who codes.
- [Architecting Trust, Module 01: How AI Actually "Thinks"](https://aragrow.me/blog/architecting-trust-how-ai-thinks/): Two simple facts about how AI works explain almost every risk you'll face: it keeps no memory of its own, and it has no built-in way to rank the instructions it reads. Here's what that means for your business.
- [Architecting Trust, Module 02: Prompt Injection, the #1 AI Risk](https://aragrow.me/blog/architecting-trust-prompt-injection/): The attack at the top of every AI risk list is made of nothing but words. Here's how prompt injection works, and the three-part combination that turns it from a prank into a breach.
- [Architecting Trust, Module 03: The Stealth Frontier](https://aragrow.me/blog/architecting-trust-stealth-frontier/): The obvious defense against prompt injection is to filter out the bad instructions.

- [Architecting Trust, Module 05: Measuring Trust](https://aragrow.me/blog/architecting-trust-measuring-trust/): A great demo is not a quality bar. How to actually prove an AI works, the three checks that catch a confident made-up answer, and five questions that reveal whether a vendor measures quality or just hopes for it.
- [Architecting Trust, Module 06: The Executive Playbook](https://aragrow.me/blog/architecting-trust-executive-playbook/): The whole guide assembled into one posture: no single wall, layered defenses that each assume the last one fails, a separation of trust to contain the worst case, and a named owner for the day it goes wrong.
- [Architecting Trust, Module 07: Your AI Readiness Self-Assessment](https://aragrow.me/blog/architecting-trust-readiness-assessment/): The interactive finale.
