用于基于DL的流量分类器更新的自主未知应用过滤和标记

Autonomous Unknown-Application Filtering and Labeling for DL-based Traffic Classifier Update

Jielun Zhang, Fuhao Li, Feng Ye, Hongyu Wu

摘要:

为了从根本上推进网络测量和管理,网络流量分类已经被广泛研究。机器学习是网络流量分类的有效方法之一。具体来说,深度学习(DL)已经引起了研究人员的广泛关注,因为它即使在加密的网络流量中也是有效的,而不会损害用户隐私和网络安全。然而,大多数现有模型都是从封闭世界数据集创建的,因此它们只能对先前采样和标记的现有类进行分类。在这种情况下,无法正确分类未知类。为了解决这个问题,提出了一个自主学习框架,以有效地更新基于DL的流量分类模型在主动操作。该框架的核心包括一个基于DL的分类器,一个自学习的分类器,和一个自主的自标记模型。自标记和自标记过程可以在主动操作期间生成新的数据集以支持分类器更新。所提出的框架的评估是在开放数据集上执行的,即,ISCX VPN-nonVPN,独立收集数据包。实验结果表明,该自主学习框架能够过滤未知类别的数据包,并提供准确的标签。因此,可以用自主生成的数据集成功地更新相应的基于DL的分类模型。

英文摘要:

Network traffic classification has been widely studied to fundamentally advance network measurement and management. Machine Learning is one of the effective approaches for network traffic classification. Specifically, Deep Learning (DL) has attracted much attention from the researchers due to its effectiveness even in encrypted network traffic without compromising neither user privacy nor network security. However, most of the existing models are created from closed-world datasets, thus they can only classify those existing classes previously sampled and labeled. In this case, unknown classes cannot be correctly classified. To tackle this issue, an autonomous learning framework is proposed to effectively update DL-based traffic classification models during active operations. The core of the proposed framework consists of a DL-based classifier, a self-learned discriminator, and an autonomous self-labeling model. The discriminator and self-labeling process can generate new dataset during active operations to support classifier update. Evaluation of the proposed framework is performed on an open dataset, i.e., ISCX VPN-nonVPN, and independently collected data packets. The results demonstrate that the proposed autonomous learning framework can filter packets from unknown classes and provide accurate labels. Thus, corresponding DL-based classification models can be updated successfully with the autonomously generated dataset.
