The Model That Wrote Your Code Can’t Secure It

A practitioner framework for governing AI-driven risk across the software development lifecycle, and why architectural independence is the only defense that holds.

LLM Application Security LPI

AI coding tools accelerate development. They also introduce vulnerabilities at scale, hallucinate security findings, and cannot audit the supply chains they’re embedded in. Asking an LLM to certify the safety of its own code is asking the student to grade their own exam. 

This paper explains why, and what to do about it.

Why LLMs cannot govern their own security, and why future better models won’t fix it

The four control points in the AI development lifecycle where independent governance must be applied
