Overview

Framework analysis demonstrates an integrated Zero Trust architecture for autonomous AI agents, highlighting enhanced accountability and runtime control in enterprise environments.

Key Points

  • To establish a comprehensive Zero Trust governance framework that addresses delegated authority, runtime tool control, and accountability for autonomous AI agents in enterprise systems.
  • Conducted a structured critical synthesis of literature across agentic AI security, machine identity, Zero Trust, runtime enforcement, and AI governance.
  • Developed the AIGATE framework comprising eight governance layers that map explicit authority and operational controls across the agent lifecycle.
  • Demonstrated practical implementation concepts using three illustrative operational scenarios spanning security operations centers, DevOps, and finance.
  • Identified persistent governance gaps in conventional IAM and Zero Trust models regarding dynamic delegated authority, intent tracking, and runtime tool use by autonomous agents.
  • Formulated the eight-layer AIGATE architecture to enforce intent-bound access, least agency, runtime tool-call control, and continuous human-attributable audit trails.
