Skill Guide
AI threat modeling is the systematic process of identifying, assessing, and mitigating security vulnerabilities and adversarial risks specific to AI/ML systems by leveraging structured threat frameworks like MITRE ATLAS, OWASP LLM Top 10, and NIST AI RMF.
Scenario
You are given access to a sample API for a customer service chatbot powered by a large language model. Your task is to perform an initial threat assessment.
Scenario
Your team has deployed a fraud detection model using transactional data. You must conduct a formal threat model before it handles production traffic.
Scenario
As a lead security architect, you are tasked with creating a repeatable threat modeling process for all AI projects in a financial institution.
MITRE ATLAS provides a knowledge base of adversary tactics and techniques against AI. OWASP LLM Top 10 lists the most critical web application security risks for LLMs. NIST AI RMF offers a governance-focused risk management structure. Use these in tandem: ATLAS/OWASP for tactical threat identification, NIST for strategic risk governance.
MLflow helps trace model/data lineage for provenance checks. Robust Intelligence and Counterfit are tools for automated adversarial testing and runtime protection. Use these to implement technical controls derived from your threat model (e.g., testing for evasion with Counterfit).
STRIDE can be adapted to categorize AI-specific threats (e.g., 'Spoofing' a model's prediction). Attack Trees help visualize complex multi-step AI attacks. Correlate AI threat models with IT security frameworks to ensure holistic defense.
Answer Strategy
Structure the answer using a phased approach: 1) Scope & Inventory (data sources, model architecture, endpoints), 2) Threat Identification (systematically apply OWASP LLM Top 10 for app-layer risks and MITRE ATLAS for adversarial ML risks), 3) Risk Assessment (prioritize using business impact, referencing NIST AI RMF for governance context), 4) Mitigation Planning (propose technical, process, and monitoring controls). Sample: 'I would begin by mapping the data flow from user input through the LLM to output, identifying all third-party components. I'd then apply the OWASP LLM Top 10 to catalog vulnerabilities like prompt injection and insecure output handling, cross-referencing MITRE ATLAS tactics like LLM Prompt Injection. Risks would be prioritized based on likelihood and impact to business operations, with mitigations such as input validation, output sandboxing, and continuous monitoring for anomalous query patterns.'
Answer Strategy
This tests communication and strategic alignment. Use the STAR method, but focus on how you translated technical AI threats into business terms (financial loss, compliance, reputational damage). Reference a framework like NIST AI RMF to structure the risk argument. Sample: 'In a previous role, our data science team wanted to deploy a predictive model with minimal input validation. I framed the threat of data poisoning not as a technical bug, but as a business continuity risk: a poisoned model could lead to catastrophic financial decisions. I presented a brief using the NIST AI RMF 'Govern' function to highlight our accountability for the model's outcomes. This led to the approval of a data provenance check and a model robustness testing phase in our MLOps pipeline.'
