本文提出一种基于Transformer和GMM的自适应网络入侵检测框架,利用BERT嵌入聚类实现未知攻击的连续识别,在检测和分类任务中分别达到100%和95.6%的召回率与准确率。

摘要:

在本文中,我们提出了一种自适应框架,用于对网络流量中的新兴攻击进行连续检测、识别和分类。该框架采用Transformer编码器架构,以双向方式捕获隐藏模式,以区分恶意流量和合法流量。最初,该框架专注于准确检测恶意活动,在区分攻击流量和良性流量方面实现了100%的完美召回率。随后,该系统通过利用高斯混合模型(GMM)对从高维BERT嵌入中提取的特征进行聚类,逐步识别未知攻击类型。这种方法使框架能够随着新攻击簇的发现而动态调整其识别能力,同时保持较高的检测精度。即使在整合了额外的未知攻击簇之后,该框架仍保持高水平性能,在分类准确率和召回率上均达到95.6%。结果表明,所提出的框架在适应不断演变的威胁的同时,在检测和识别任务中均保持了高精度,验证了其有效性。我们的最终目标是开发一个可扩展的、实时的入侵检测系统,使其能够随着不断变化的网络威胁态势持续演进。

英文摘要:

In this paper, we present an adaptive framework designed for the continuous detection, identification and classification of emerging attacks in network traffic. The framework employs a transformer encoder architecture, which captures hidden patterns in a bidirectional manner to differentiate between malicious and legitimate traffic. Initially, the framework focuses on the accurate detection of malicious activities, achieving a perfect recall of 100\% in distinguishing between attack and benign traffic. Subsequently, the system incrementally identifies unknown attack types by leveraging a Gaussian Mixture Model (GMM) to cluster features derived from high-dimensional BERT embeddings. This approach allows the framework to dynamically adjust its identification capabilities as new attack clusters are discovered, maintaining high detection accuracy. Even after integrating additional unknown attack clusters, the framework continues to perform at a high level, achieving 95.6\% in both classification accuracy and recall.The results demonstrate the effectiveness of the proposed framework in adapting to evolving threats while maintaining high accuracy in both detection and identification tasks. Our ultimate goal is to develop a scalable, real-time intrusion detection system that can continuously evolve with the ever-changing network threat landscape.
