The document identifies five broad categories of risk:
  • Privilege: When agents are granted too much access, a single compromise can cause far more damage than a typical software vulnerability.
  • Design and configuration flaws, where poor setup creates security gaps before a system even goes live.

  • Structural risk, where interconnected networks of agents can trigger failures that spread across an organization’s systems.
