UnverifiedGuards sit between the model and the tool functions, bearing responsibility for safety validation by checking before any tool is called, and are a key mechanism for defending against prompt injection and abnormal operations.73% similarUnverifiedAn effective prompt injection defense system typically requires a combination of input content filtering, instruction source tracing, and pre-execution intent verification, as relying solely on the model's own safety training is insufficient to resist adversarial examples.71% similarUnverifiedBy cross-comparing malicious injection scenarios with benign control scenarios, test results can be classified into four categories: true security, false security, security vulnerability, and over-defense.70% similarUnverifiedA safety probe is a defense mechanism that detects malicious prompts by reading vectors from the model's internal hidden layers, without relying on the model's output.69% similar
