IPIGuard: A Novel Tool Dependency Graph-Based Defense Against Indirect Prompt Injection in LLM Agents (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for detecting Indirect Prompt Injection (IPI) attacks rely on assumptions about the model's inherent security, which lacks structural constraints on agent behaviors. |
| Approach: | They propose a novel task execution paradigm that models the agents’ task execution process as a traversal over a planned Tool Dependency Graph (TDG). |
| Outcome: | The proposed model reduces unintended tool invocations triggered by injected instructions, enhancing robustness against IPI attacks. |
