Skill Guide
The practice of governing the development, deployment, and operation of AI systems to protect data, ensure model integrity, and adhere to legal, regulatory, and ethical standards.
Scenario
You are given a basic Python ML project skeleton using scikit-learn and pandas for a toy dataset. The project has no security considerations.
Scenario
Deploy a pre-trained sentiment analysis model behind a REST API (using Flask or FastAPI) that must be production-ready for a customer-facing application.
Scenario
A healthcare startup wants to deploy an AI tool that suggests potential diagnoses based on clinician notes. The tool will process sensitive patient health information (PHI).
Apply for specific technical controls: TensorFlow Privacy/Opacus for implementing differential privacy in model training; Seldon Core/KServe for building secure, scalable model serving with built-in observability; Vault for secrets management (API keys, database credentials) in pipelines; Censius/Arthur AI for continuous monitoring of model performance, bias, and drift in production.
Use as governance and assessment blueprints: NIST AI RMF and ISO 42001 for building a comprehensive, auditable AI governance program; OWASP LLM Top 10 to identify and mitigate specific vulnerabilities in large language model applications; MITRE ATLAS to understand the adversarial tactics and techniques targeting ML systems.
Answer Strategy
Use the MLOps lifecycle as your framework. A strong answer will map specific security practices to each phase: (1) Data: provenance tracking, consent management, minimization; (2) Development: secure coding, dependency scanning; (3) Training: privacy-preserving techniques, access logs; (4) Deployment: secure serving, API hardening; (5) Monitoring: drift detection, adversarial monitoring; (6) Retirement: secure data/model deletion. Sample: 'I embed security gates throughout our MLOps pipeline. For data, we enforce cataloging and anonymization in our feature store. During development, we run SAST/DAST scans on notebooks and require peer review for model code. In deployment, models are served via containers with non-root users, and endpoints are protected by OAuth. We continuously monitor for data drift and model integrity in production using a platform like Arthur, with clear runbooks for incident response.'
Answer Strategy
Tests knowledge of third-party risk and specific LLM threats. The response should address: (1) Data sovereignty: where is the prompt/response data processed and stored? (2) Model security: potential for prompt injection, data leakage from training data, and lack of audit trails. (3) Compliance: does the provider's data processing agreement (DPA) meet GDPR/CCPA requirements? (4) Operational risk: lack of control over model updates and potential for downtime. Strategy: Propose a formal vendor security assessment, a proof-of-concept in a sandboxed environment with synthetic data only, and a clear data processing addendum before any real customer data is used.
