|Issue Date:||2022-04-01 15:01:32 (UTC+8)|
|Abstract:||隨著資安攻擊和數據洩露的迅速增加，資訊安全已成為全球關注的重要問題。人工智慧可以幫助人類自動分析攻擊，特別是分析攻擊意圖以生成威脅情報。基此，本研究旨在透過人工智慧模型自動地識別封包的攻擊意圖。我們提出一個基於 Transformer 的語言模型，藉由分析 MITRE 網站上的文章來學習戰術（意圖）和攻擊封包之間的關係。該模型嵌入一個封包並輸出一個表示封包內容及其意圖的高維向量。本研究亦建立一套標籤數據集生成流程，使用無監督學習方法生成用於訓練語言模型的標籤數據，有效減輕人工標記大數據資料集的負擔。實驗結果顯示，本研究微調的多標籤分類語言模型在識別封包攻擊戰術的 F1 分數為 1。|
Cybersecurity has become a primary global concern with the rapid increase in security attacks and data breaches. Artificial intelligence can help humans analyze attacks, specifically to generate threat intelligence. This study aims to automatically identify the intention of attack packets through an artificial intelligence model. We propose a Transformer-based language model that learns the relationship between tactics (intentions) and attack packets by analyzing the articles on the MITRE website. The model embeds a packet and outputs a high-dimensional vector representing packet content and its intent (if any). This study also establishes a label dataset generation process by using an unsupervised learning method to generate label data for training language models, effectively reducing the burden of manually labeling big data datasets. The experimental results show that the multi-label classification language model fine-tuned in this study has an F1 score of 1 for identifying packet attack tactics.
