JBShield is a groundbreaking defense mechanism that analyzes and manipulates activated concepts to protect Large Language Models from malicious jailbreak attacks.

• Uses Linear Representation Hypothesis to understand how jailbreak attacks bypass safety guardrails
• Identifies and manipulates safety-critical concepts to detect and neutralize attacks
• Demonstrates superior performance compared to existing defense methods
• Provides a more durable solution by addressing the underlying mechanisms of jailbreaks

This research addresses critical security vulnerabilities in LLMs, offering organizations a stronger shield against attacks that could potentially extract harmful content, sensitive information, or bypass content policies.
