摘要:

互联网已经成为安全攻击和入侵者的主要对象。这些攻击可能导致系统故障、网络崩溃、数据损坏或被盗。网络入侵检测系统(IDS)是一种通过观察网络流量来识别未经授权和恶意行为的工具。最先进的入侵检测系统被设计成通过检查关于攻击的完整信息来检测攻击。这意味着IDS只能在攻击在受到攻击的系统上执行并可能对系统造成损害之后才能检测到攻击。在本文中,我们提出了一个端到端的早期入侵检测系统,以防止网络攻击之前,他们可能会造成任何更多的损害,系统受到攻击,同时防止不可预见的停机和中断。我们采用基于深度神经网络的分类器进行攻击识别。该网络以监督的方式进行训练,以从原始网络流量数据中提取相关特征,而不是依赖于大多数相关方法中使用的手动特征选择过程。此外,我们引入了一个新的度量,称为早期,以评估我们提出的方法检测攻击的早期程度。我们在CICIDS2017数据集上对我们的方法进行了经验评估。结果表明,我们的方法表现良好,达到了0.803的整体平衡精度。

英文摘要:

The Internet has become a prime subject to security attacks and intrusions by attackers. These attacks can lead to system malfunction, network breakdown, data corruption or theft. A network intrusion detection system (IDS) is a tool used for identifying unauthorized and malicious behavior by observing the network traffic. State-of-the-art intrusion detection systems are designed to detect an attack by inspecting the complete information about the attack. This means that an IDS would only be able to detect an attack after it has been executed on the system under attack and might have caused damage to the system. In this paper, we propose an end-to-end early intrusion detection system to prevent network attacks before they could cause any more damage to the system under attack while preventing unforeseen downtime and interruption. We employ a deep neural network-based classifier for attack identification. The network is trained in a supervised manner to extract relevant features from raw network traffic data instead of relying on a manual feature selection process used in most related approaches. Further, we introduce a new metric, called earliness, to evaluate how early our proposed approach detects attacks. We have empirically evaluated our approach on the CICIDS2017 dataset. The results show that our approach performed well and attained an overall 0.803 balanced accuracy.
