Creating Effective Sigma Rules with AI

Creating Effective Sigma Rules with AI

Can Threat Detection be enhanced with AI? Ashish sat down with Dave Johnson, Senior Threat Intelligence Advisor at Feedly, at BSides SF 2024, where Dave also presented a talk.

Dave shares his journey in cyber threat intelligence, including his 15-year career with the FBI and his transition to the private sector. The conversation focuses on the innovative use of large language models (LLMs) to create Sigma rules for threat detection and the challenges faced along the way. Dave spoke about his four approaches to creating Sigma rules with AI, ultimately highlighting the benefits of prompt chaining and Retrieval Augmented Generation (RAG) systems.
