“…As the production line has been expanded with IoT devices to enable communication with the Industry 4.0 concept, which also enables communication via the external WAN environment, it is also more vulnerable to possible attacks from the external network. Another major disadvantage of the Fibaro IoT device and thermostat is that these devices are very poorly secured, as has been demonstrated in recent research on these IoT devices [58]. In order to perform test scenarios in the form of cyber-attacks, the attacks were led from a single personal computer.…”

Internet of Things (IoT) devices are not only finding increasing use in ordinary households, but they have also become a key element for the Industry 4.0 concept. The implementation of industrial IoT devices into production streamlines the production process and reduces production costs. On the other hand, connected IoT devices bring new security risks to production and expose an industrial environment to new types of attacks. The article analyzes the vulnerability of the production line with implemented industrial IoT devices with consideration of a possible Distributed Denial-of-service (DDoS) attack led by attackers from the internet. Various types of DDoS attacks abusing the presence of IoT devices in the system were performed on an automated production line implementing sorting, preparation, and dosing of bulk and liquid materials for filling into containers. The leading attacks caused failure of the production line during the production, as well as the dysfunction of communication with IoT devices. The article also demonstrates the implementation of countermeasures against DDoS attacks and possible strategies to protect and mitigate such attacks on the production line.

“…The tests were performed in three different scenarios, each lasting 90 s on the same network topology. The authors' previous experience with DDoS attacks [17,28,30] conducted on various devices, pointed to the fact that a medium-sized botnet, as used in the experiments in the article, can completely flood the device in 60 s, and the experiment will show the result. Another 30 s were examined to capture the recovery of the IoT device after the end of the 60 s attack.…”

“…Our previous experience with the Fibaro Home Center Lite small gateway and the Honeywell thermostat already points to the fact that it is possible to use a DDoS attack to disable a specific IoT device during the attack and prevent communication between the smart home user and the IoT device, thus preventing communication and collecting information from the IoT sensor. The Honeywell thermostat was unable to send an alarm notification to the mobile application and so failed to inform in time the smart home user of the threats detected by the sensor during the attack [30].…”

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.
