One-day workshop by Thomas Vissers and Tim Van Hamme
Large Language Models (LLMs) open up a new realm of possibilities in application development, but they also pose significant challenges. Their non-deterministic nature and broad use cases complicate testing, while unpredictable failures (“hallucinations”) and novel attack vectors (“prompt injections”) add risk.
This workshop covers LLM-based applications, highlights unique threats, and offers hands-on testing and hardening techniques. Attendees will learn to set up and secure basic LLM-driven solutions in their organizations.
Learning goal: Learn how LLM applications work and are architected, the unique security challenges they introduce, and the current best practices in LLM security—along with their limitations.
