Smart devices along with sensors are gaining in popularity with the promise of making life easier for the owner. As the number of sensors in an Internet of Things (IoT) system grows, a question arises as to whether the transmission between the sensors and the IoT devices is reliable and whether the user receives alerts correctly and in a timely manner. Increased deployment of IoT devices with sensors increases possible safety risks. It is IoT devices that are often misused to create Distributed Denial of Service (DDoS) attacks, which is due to the weak security of IoT devices against misuse. The article looks at the issue from the opposite point of view, when the target of a DDoS attack are IoT devices in a smart home environment. The article examines how IoT devices and the entire smart home will behave if they become victims of a DDoS attack aimed at the smart home from the outside. The question of security was asked in terms of whether a legitimate user can continue to control and receive information from IoT sensors, which is available during normal operation of the smart home. The case study was done both from the point of view of the attack on the central units managing the IoT sensors directly, as well as on the smart-home personal assistant systems, with which the user can control the IoT sensors. The article presents experimental results for individual attacks performed in the case study and demonstrates the resistance of real IoT sensors against DDoS attack. The main novelty of the article is that the implementation of a personal assistant into the smart home environment increases the resistance of the user’s communication with the sensors. This study is a pilot testing the selected sensor sample to show behavior of smart home under DDoS attack.

IoT传感器在智能家居环境中抵抗DDoS攻击的能力。

随着传感器的普及，智能设备和传感器正日益普及，并有望使所有者的生活更加轻松。随着物联网（IoT）系统中传感器的数量的增加，出现了一个问题，即传感器与IoT设备之间的传输是否可靠以及用户是否正确，及时地收到警报。带有传感器的物联网设备部署的增加会增加安全隐患。物联网设备经常被滥用来创建分布式拒绝服务（DDoS）攻击，这是由于物联网设备防止滥用的安全性较弱。当DDoS攻击的目标是智能家居环境中的IoT设备时，本文从相反的角度看问题。本文研究了物联网设备和整个智能家居如果从外部成为针对智能家居的DDoS攻击的受害者将如何表现。有人提出了安全性问题，即合法用户是否可以继续控制并从IoT传感器接收信息，这在智能家居的正常运行期间可用。从直接管理IoT传感器的中央单元以及用户可以控制IoT传感器的智能家居个人助理系统受到攻击的角度出发，进行了案例研究。本文介绍了案例研究中针对单个攻击的实验结果，并演示了真正的物联网传感器对DDoS攻击的抵抗力。该文章的主要新颖之处在于，将个人助理实施到智能家居环境中会增加用户与传感器通信的阻力。这项研究是对所选传感器样本进行测试以显示智能家居在DDoS攻击下的行为的试验。
