CISO Decision Guide for AI Security Governance

This guide is designed for Chief Information Security Officers (CISOs), security architects, and AI program owners who are tasked with governing AI adoption while maintaining the ability to reconstruct actions taken by AI agents. It outlines the evolving landscape of security as AI systems become more autonomous, emphasizing the need for a robust evidence architecture that can track agent actions, decisions, and tool interactions. The document details the shift from pre-AI to post-AI security controls, highlighting the importance of managing not just access but also the decisions made by AI agents. It identifies two foundational problems that define the next era of security and presents a framework for using governed agents to enhance investigation and response capabilities. Additionally, the guide discusses the critical decisions that CISOs must make regarding agent governance, supply chain management, identity and privilege control, data exposure, and incident response, stressing the necessity of having a comprehensive view of actions taken across systems to ensure effective security management.
