摘要
随着物联网(IoT)的快速发展,越来越多的IoT节点设备被部署,但伴随而来的安全问题也不可忽视。IoT的网络层节点设备主要通过无线传感网进行通信,其相较于互联网更开放也更容易受到拒绝服务等网络攻击。针对无线传感网面临的网络层安全问题,提出了一种基于序列模型的网络入侵检测系统,对网络层入侵进行检测和报警,具有较高的识别率以及较低的误报率。另外,针对无线传感网节点设备面临的节点主机设备的安全问题,在考虑节点开销的基础上,提出了一种基于简单序列模型的主机入侵检测系统。实验结果表明,针对无线传感网的网络层以及主机层的两个入侵检测系统的准确率都达到了99%以上,误报率在1%左右,达到了工业需求,这两个系统可以全面有效地保护无线传感网安全。
With the rapid development of Internet of Things(IoT),more and more IoT node devices are deployed,but the accompanying security problem cannot be ignored.Node devices at the network layer of IoT mainly communicate through wireless sensor networks.Compared with the Internet,they are more open and more vulnerable to network attacks such as denial of service.Aiming at the network layer security problem faced by wireless sensor networks,a network intrusion detection system based on sequence model was proposed to detect and alarm the network layer intrusion,which achieved higher recognition rate and lower false positive rate.Besides,aiming at the security problem of the node host device faced by wireless sensor network node devices,with the consideration of the node overhead,a host intrusion detection system based on simple sequence model was proposed.The experimental results show that,the two intrusion detection systems for the network layer and the host layer of wireless sensor network both have the accuracy more than 99%,and the false detection rate about 1%,which meet the industrial requirements.These two proposed systems can comprehensively and effectively protect the wireless sensor network security.
