🔐 Google SAIF (Secure AI Framework) – Summary
SAIF is Google’s proposed Secure AI Framework designed to help organizations secure AI systems in a structured and comprehensive way. It builds on Google’s security expertise and aligns with secure software development practices, adapted specifically for AI/ML systems.
🎯 SAIF Goals
- Provide a security-by-design approach for AI.
- Address emerging AI-specific threats (e.g., prompt injection, model theft).
- Guide organizations in building and maintaining trustworthy AI systems.
🧱 Core Pillars of SAIF
1. Secure the AI System Architecture
- Apply Zero Trust principles to AI pipelines.
- Ensure segmentation, least privilege, and secure interfaces (e.g., APIs).
2. Secure the AI Supply Chain
- Validate and verify data, models, and dependencies.
- Use software bills of materials (SBOM) and signed artifacts.
- Prevent data poisoning and model tampering.
3. Secure the AI Model
- Protect models from:
- Adversarial inputs
- Prompt injection
- Model inversion and theft
- Implement robustness testing, model watermarking, and access controls.
4. Secure the AI Usage
- Monitor and control inputs and outputs.
- Implement rate limiting, policy enforcement, and content filtering.
- Defend against abuse like jailbreaking and misuse of outputs.
5. Secure the Deployment Environment
- Harden infrastructure: secure model hosting, inference APIs, and GPU/TPU environments.
- Use encryption in use, confidential computing, and MLOps security.
6. Secure the People and Processes
- Define clear roles/responsibilities for AI security.
- Train developers and operators on AI risks and response.
- Conduct red teaming, threat modeling, and incident response planning.
✅ Key Principles Behind SAIF
| Principle | Description |
|---|---|
| Defense in Depth | Layered security across the entire AI lifecycle |
| Threat-Informed | Uses real-world threats and frameworks like MITRE ATLAS |
| Built-in Security | Security from the start—not bolted on later |
| Adaptable | Works across organizations of different sizes and industries |
