Merged summary

TL;DR - This paper reframes agent security as a contextual authorization problem rather than one of detecting malicious-looking actions. It proposes four continuously evaluated properties to better define attacks, defenses, and benchmarks.

  • Source Authorization verifies who issued each command.
  • Task and Action Alignment ensure actions serve the agent’s authorized objective.
  • Data Isolation controls information flow across privilege boundaries.
  • The framework casts indirect prompt injection as an authorization violation and argues snapshot benchmarks cannot adequately assess data isolation.
