How to Secure an AI System
To secure an AI system, address both standard software security and AI-specific risks: defend against prompt injection with input and output filtering, minimize and protect sensitive data in prompts and logs, apply least-privilege to any tools or actions the AI can take, add guardrails that limit outputs and behaviors, and monitor for abuse and anomalies. For agents that take actions, require permissions and human approval for sensitive steps. Security must be designed in from the start, not added after an incident.
AI adds new attack surfaces to normal software risk. Here's a practical checklist to secure an AI system—from prompt injection to over-permissioned agents.
Cover both layers
Secure standard software (auth, access, encryption) plus AI-specific risks—see securing AI systems and enterprise AI security.
The AI-specific steps
| Risk | Defense |
|---|---|
| Prompt injection | Input/output filtering |
| Data leakage | Minimize data in prompts/logs |
| Model/API abuse | Rate limits, auth |
| Over-permissioned agents | Least-privilege |
Defend against prompt injection
Filter inputs and outputs, don't trust model output for sensitive actions without checks, and separate trusted instructions from untrusted content—see what is prompt injection.
Protect data
Minimize sensitive data in prompts and logs, encrypt it, and enforce access control—the data privacy discipline, including for offshore work.
Secure agents with least-privilege
An agent that takes actions is a bigger target. Give it least-privilege, scope actions tightly, require approval for sensitive steps, and log everything—see AI agent security risks and guardrails.
Monitor and respond
Monitor for abuse and anomalies, and have an incident response plan ready.
Design it in
AI security can't be bolted on after an incident—it's designed into data flow, access, and agent permissions from the start.

Questions raised by this field note.
Straightforward guidance for evaluating scope, fit, and the next step.
01How do I secure an AI system?
Address standard software security plus AI-specific risks: defend against prompt injection, protect data in prompts and logs, apply least-privilege to tools and actions, add guardrails, and monitor for abuse. For agents, require permissions and human approval for sensitive steps.
02What are the main AI-specific security risks?
Prompt injection, data leakage through prompts and outputs, model and API abuse, poisoned training data, and over-permissioned agents taking unintended actions. Each needs specific defenses beyond normal software security.
03How do I secure an AI agent?
Give it least-privilege access, scope its actions tightly, require approval for sensitive operations, validate its actions, log everything, and keep a human in the loop for high-stakes steps. An over-permissioned agent is a major risk.
