Control

Mechanisms for overseeing and constraining an AI system's behavior, from input limits and guardrails to monitoring, human override, and kill switches.
What is Control?
Control in AI is the set of mechanisms for overseeing and constraining an AI system’s behavior so that it stays within the bounds its operators intend.
The mechanisms range from hard limits coded into the system to organizational processes that keep people able to step in. What unites them is direction: a controlled system can be stopped, corrected, or overridden by its operators; an uncontrolled one does whatever its training and inputs produce.
Types of AI Controls
Auditors sort controls by when they act, and the scheme transfers cleanly to AI.
- Preventive controls stop unwanted behavior before it happens: input filters, guardrails on what the system will discuss or do, permission boundaries, and caps on the size or rate of actions it takes.
- Detective controls surface problems as they occur: logging every action, monitoring outputs for anomalies, and alerting when behavior drifts from the norm.
- Corrective controls restore safe operation once something goes wrong: human override, rollback to a previous model version, and a kill switch that halts the system outright. Human-in-the-loop design goes further and requires a person’s approval before any output takes effect, which turns every decision into a checkpoint.
Example of AI Controls
The cost of missing controls has a precise price tag. On 1 August 2012, Knight Capital deployed faulty trading software that began flooding the US stock market with unintended orders.
No pre-trade limit stopped the orders (a preventive control), no alert isolated the malfunctioning servers fast enough (detective), and the firm had no practiced procedure for shutting the system down (corrective). In roughly 45 minutes, Knight lost about $440 million and nearly collapsed.
The same anatomy applies to AI systems that act autonomously: action limits bound what any single run can do, live monitoring catches abnormal behavior in minutes rather than quarters, and a rehearsed shutdown path means someone can actually pull the plug.
