Evaluating Prompt Injection Defenses for Educational LLM Tutors: Security-Usability-Latency Trade-offs
Researchers evaluated prompt-injection defenses for educational LLM tutors, revealing inherent trade-offs between security, usability, and speed. A multi-layer safeguard pipeline achieved 46.34% attack bypass with zero false positives and 2.50ms latency, while competing systems like NeMo Guardrails eliminated bypasses but suffered 16.22% false positive rates and 1.3-second delays.
