Title: Building AI-Driven Cyber Defense Agents: From Theory to Practice

Large language models (LLMs) are opening up new possibilities in cybersecurity, from detecting threats to generating real-time responses. This tutorial explores how LLMs—
when combined with the LangChain framework—can be used to build intelligent and modular cyber defense agents. We start with the basics of using LLMs in cybersecurity,
including prompt design, chaining logic, memory, and interactive reasoning. Then, we show how LangChain can bring these pieces together to create systems that detect attacks, explain decisions, and suggest mitigation steps. We focus on building pipelines that use retrieval-augmented generation (RAG) to pull in threat intelligence and logs, helping
LLMs respond with context-aware answers. We also highlight how explainable AI can surface key indicators of attacks and guide response generation. Finally, we discuss
how to integrate external tools and APIs for automated mitigation.

Title: Intelligent Meta-Surfaces Assisted Unmanned Aerial Vehicle Networks: Revolutionizing 6G and Beyond

Unlocking the connectivity and efficiency of 6G networks involves exploring cutting-edge technologies like meta-surface.Meta-surfaces, also known as intelligent reflecting
surfaces (IRS), are metamaterials engineered with properties not found in naturally occurring materials. Reflecting on their potential, these surfaces could revolutionize wireless communication by manipulating electromagnetic waves in novel ways. IRS-assisted Unmanned Aerial Vehicle (UAV) networks are emerging as a promising solution to enhance
wireless communication coverage, reliability, and spectral efficiency in dynamic environments. By integrating IRS technology with UAV platforms, these networks can intelligently reconfigure the wireless propagation environment to support flexible deployment, energy-efficient transmissions, and improved user connectivity. This talk provides a concise overview of the key benefits,
challenges, and applications of IRS-assisted UAV networks, highlighting their potential in next-generation wireless systems such as disaster recovery, remote sensing, and mobile edge computing.
