论文摘要
入侵检测是提供计算机网络安全性的重要机制之一。由于攻击的增加以及对医学,商业和工程等其他领域的依赖不断增加,因此通过网络提供服务并维持网络安全已成为一个重大问题。入侵检测系统(IDS)的目的是开发能够将常规通信与异常通信区分开的模型,并采取必要的行动。在该领域的不同方法中,人工神经网络(ANN)已被广泛使用。但是,基于ANN的ID遇到了两个主要问题:低检测精度和弱检测稳定性。为了克服这些问题,本文提出了一种基于深神经网络ANS支持向量机分类器的新方法,该方法受到“分裂和征服”哲学的启发。提出的模型以更好的准确性来预测攻击,以使入侵检测相当相似。对于我们的实证研究,我们利用了KDD99数据集。我们的实验结果表明,新方法提高了95.4%的分类精度。
Intrusion detection is one of the important mechanisms that provide computer networks security. Due to an increase in attacks and growing dependence upon other fields such as medicine, commerce, and engineering, offering services over a network and maintaining network security have become a significant issue. The purpose of Intrusion Detection Systems (IDS) is to develop models which are able to distinguish regular communications from abnormal ones, and take the necessary actions. Among different methods in this field, Artificial Neural Networks (ANNs) have been widely used. However, ANN-based IDS encountered two main problems: low detection precision and weak detection stability. To overcome these problems, this paper proposes a new approach based on Deep Neural Network ans Support vector machine classifier, which inspired by "divide and conquer" philosophy. The proposed model predicts the attacks with better accuracy for intrusion detection rather similar methods. For our empirical study, we were taking advantage of the KDD99 dataset. Our experimental results suggest that the new approach enhance to 95.4 percent classification accuracy.
