Abstract
當前的資安事件經常給企業或組織帶來巨大的損失,因此資安分析師需要快速利用洩露的資訊來獲取有價值的資訊。本研究結合大語言模型技術和Retrieval-Augmented Generation (RAG) 方法,應用於實際的資安分析事件。透過RAG技術,我們能夠從大量的對話紀錄中有效識別每段對話的關鍵點、參與者和討論主題等重要訊息,大幅節省資安事件調查的時間成本。 同時,考量到商業應用和資料隱私,我們使用LLaMA2和QLoRA微調的生成式模型,確保提示語(Prompt)資料保存在本地端環境中,並達到如GPT-4般精準的回應。最後,我們展示了如何利用RAG模型協助進行資安分析,突顯資安分析師關注的重點。
