CAISO GRC Methodology

A comprehensive framework for AI security governance, risk management, and compliance

Methodology Overview

Introduction to the CAISO GRC Framework

The CAISO Governance, Risk, and Compliance (GRC) Framework provides a structured approach to managing the unique security challenges presented by AI systems while integrating with existing cybersecurity GRC practices. This comprehensive methodology addresses the full spectrum of AI security governance, from policy development to risk management to regulatory compliance.

Traditional cybersecurity GRC approaches often fail to adequately address the unique characteristics of AI systems, including model-specific vulnerabilities, data governance requirements, ethical considerations, and emerging AI-specific regulations. The CAISO GRC Framework bridges this gap by providing specialized methodologies and tools while maintaining alignment with enterprise security objectives.

Core Principles

  • Integrated Approach: Combines AI governance with cybersecurity governance for comprehensive coverage
  • Risk-Based Prioritization: Focuses resources on the highest-risk AI systems and components
  • Continuous Assessment: Implements ongoing monitoring rather than point-in-time assessments
  • Adaptive Response: Evolves with the changing AI threat landscape and regulatory environment
  • Collaborative Governance: Engages stakeholders across the organization in AI security governance
  • Transparent Accountability: Establishes clear ownership for AI security risks
  • Ethical Foundation: Incorporates ethical considerations into all aspects of AI security governance

Framework Components

CAISO GRC Framework Components
