AI Agent Threat Model · Production-Ready Guide

AI Agent Threat Modeling — Your Agent Went Into Production Without Threat Model Last Night and Was Compromised by Prompt Injection.

Your agent had no threat model, no STRIDE analysis and no security controls. A prompt injection attack compromised all agents. 12,000 compromised sessions, data exfiltration, your CTO called the CSO. Here's how to prevent it.

What is Threat Modeling? Simply explained.

Think of threat modeling like a risk analysis before building a house: you want to know what dangers exist before you build. For AI agents, this means: STRIDE analysis for attack vectors, asset identification for critical components, risk assessment for prioritization and security controls for protection. Good threat modeling means: STRIDE, asset ID, risk assessment and security controls.

Real-World Scars: Production Incidents

SCAR #1: Prompt Injection without Threat ModelCRITICAL

Prompt injection attack without threat model. 12,000 compromised sessions, data exfiltration. Fix: Threat model, STRIDE analysis.

Root Cause: No threat model. Lessons: Enable threat model with STRIDE analysis.

SCAR #2: Data Poisoning without Asset IDHIGH

Data poisoning without asset identification. Training data compromised, model behavior changed. Fix: Asset identification, data provenance.

Root Cause: No asset identification. Lessons: Enable asset identification with data provenance.

Immediate Actions: What to do today?

Enable STRIDE Analysis

Enable STRIDE threat modeling for all AI agents.

Enable Asset Identification

Enable asset identification for critical components.

Enable Security Controls
