Zero Trust

A security model requiring continuous verification for every request, assuming no implicit trust regardless of origin. Core principles include least privilege access, micro-segmentation, and never trust, always verify.

Key Principles

• Verify explicitly before granting access
• Enforce least privilege for all entities
• Assume breach in all environments
• Secure all data in transit and at rest

Zero Trust for AI Agents (IBM, Jeff Crume)

• Agentic AI (systems that act, not just think) expands attack surface through API interactions, tool calls, data movement, and sub-agent creation
• Requires Zero Trust applied to:
  • Agent-to-agent communication
  • Agent-to-API call validation
  • Data flow security
  • Sub-agent authorization
• Traditional security models insufficient for autonomous agent ecosystems

  • Speaker: Jeff Crume, IBM Distinguished Engineer
  • Context: Age of Agentic AI—systems that act (API interactions, tool calls, transactions, data movement)
  • Key points:
    • Zero Trust principles applied to AI agents
    • Continuous verification for agent actions
    • Secure data flow and sub-agent authorization
