AI Security Governance Model

This document outlines a comprehensive governance structure for managing adversarial security risks in AI systems, establishing clear organizational responsibilities, oversight mechanisms, and accountability frameworks.

Governance Structure Overview

The AI security governance model is structured in five interconnected layers:

1. Strategic Governance: Board and executive leadership
2. Tactical Oversight: Security management and program governance
3. Operational Implementation: Day-to-day security operations
4. Technical Execution: Security engineering and technical controls
5. Verification & Validation: Independent assessment and assurance

This layered approach ensures that security governance extends from strategic direction through to technical implementation and independent validation.

Implementation Framework

To implement this governance model effectively, organizations should follow these key steps:

1. Governance Foundation

Establish the fundamental governance elements:

1. Security Charter: Document defining the security mission and authority
2. Policy Framework: Hierarchical policy structure from principles to procedures
3. Committee Structure: Formal establishment of governance committees
4. Responsibility Assignment: Clear documentation of roles and accountabilities

2. Risk Management Integration

Embed risk management throughout the governance structure:

1. Risk Appetite Definition: Board-approved statement of risk tolerance
2. Risk Assessment Methodology: Standardized approach to risk evaluation
3. Risk Register: Centralized tracking of security risks
4. Risk Treatment Process: Structured approach to risk mitigation

3. Metrics and Reporting

Implement measurement and reporting mechanisms:

1. Metric Definition: Clear definition of key performance indicators
2. Data Collection: Reliable processes for gathering security metrics
3. Reporting Framework: Standardized reporting at appropriate governance levels
4. Dashboard Development: Visual representation of security posture

4. Governance Maturity Evolution

Plan for governance evolution over time:

1. Maturity Assessment: Baseline evaluation of governance maturity
2. Improvement Roadmap: Phased plan for governance enhancement
3. Capability Development: Systematic building of governance capabilities
4. Continuous Evaluation: Ongoing assessment of governance effectiveness
