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.參考文獻 [1] A. Vaswani, N.
