Introduction

AI agents are not just chatbots. They call tools, read data, and take actions. That makes access control and monitoring critical. This article explains what goes wrong, why it is not theoretical, and how to implement controls that actually stop attacks.

What is AI agent security?

AI agent security is the practice of constraining what an agent can do and observing what it actually does. It combines traditional access control with runtime monitoring tailored to the non-deterministic behavior of LLMs.

Best practices for implementing LLM access controls and monitoring

The specific question is: how do you implement access controls and monitoring for LLM-based agents? The answer starts with recognizing that the model is an untrusted component. You cannot rely on prompt instructions to enforce security.…
