Lakera's research paper, "Gandalf the Red: Adaptive Security for LLMs," addresses the need for adaptive defenses in the rapidly evolving landscape of Large Language Model (LLM) security, emphasizing that static defenses are insufficient against increasingly sophisticated attackers. The study introduces the Dynamic Security and Utility Threat Model (D-SEC), which helps balance the trade-offs between security and usability, highlighting the importance of adaptive defenses that evolve alongside attacker strategies. Key strategies outlined include restricting application scope, implementing defense-in-depth, and leveraging adaptive security measures based on user behavior to enhance protection without significantly degrading usability. The research also showcases Gandalf, a gamified red-teaming platform that aids in uncovering LLM vulnerabilities by leveraging human creativity and interactive feedback, thus informing the development of more robust security strategies. The findings underscore the challenge of maintaining a balance between robust security measures and maintaining a positive user experience, particularly in the context of LLM applications.
