Artificial Neural Network Based DGA Botnet Detection
Authors: Wu Jiaxuan
Published: July 2020

In the recent years, botnet has become a serious threat to network security. As the result, the botnet detection solution is becoming an important topic for network security. DNS request is usually the first step to contact the C&C server of the bots controlled by the bot master and the detection of the DNS request domains is an effective way in detecting the bots. However, most botnets based on DNS protocol adopt Domain Generation Algorithm (DGA), which can change the domain randomly to hide themselves. Therefore, the traditional signature-based approach is rendered ineffective. Compared with the conventional ways of detection, the detection based on machine learning can obtain better detection result. In this work, we propose a botnet detection architecture based on Artificial Neural Network. We implement and evaluate the practicability of this solution with real datasets.

Published: July 2020

Major traffic accidents caused by snow cover and ice on pavements are responsible for large numbers of casualties and extensive property losses each year around the globe. A full-scale heat-pipe-based active snow-melting test system for outdoor asphalt roads was constructed to study and analyze its working performance on in-service asphalt highways. Based on long-term monitoring data, the active snow-melting system was analyzed to determine the temperature-field distribution pattern and relevant influencing factors as well as its performance on asphalt pavements. The research results show that: (1) the system exhibited excellent performance. Three natural snowfall events occurred on the full-scale test platform. In each event, the snow-melting system was able to effectively melt the snow. (2) Under long-term low-temperature conditions in winter, the active snow-melting system was able to increase the pavement temperature by approximately 10 °C. (3) In winter, the underground soil temperature decreased by approximately 4 °C as a result of heat extraction by the underground heat pipes and gradually recovered to its previous level as the outdoor ambient temperature gradually increased. This finding suggests that underground soil can provide heat to the snow-melting system for an extended period of time and continuously ensure its pavement snow-melting performance. The engineering application on the G18 Highway further demonstrates the effectiveness and reliability of active snow-melting systems based on heat-pipe technology.

Published: July 2020

With the development of times and technology, the iprovement of technology has promoted the progress of blueberry juicing device at the same time. However, there are still defects. The current blueberry juicing device cannot improve the yield and anthocyanin content. Therefore, it is easy to waste raw materials. So a device to improve the juice yield and anthocyanin content in blueberry juice is designed to solve this problem. The device enables the squeezed residue discharged into the distillation drum through the slag discharge tube. At the same time, citric acid and sucrose solution is added into the distillation cylinder combined with solution storage tank. Hence it enables the heating of the heating silk base and make a small amount of juice in the residue extracted and evaporated under acidic conditions. Meanwhile, it is conducive to the dissolution of anthocyanins in the residue so that the evaporated steam is discharged into the cooling tube through the distillation tube for condensation and then into the collection tube for collection. The device can improve the juice yield and anthocyanin content of blueberry juice.

Published: July 2020

The application of distributed power in the system has changed many characteristics of the traditional distribution network. Based on the consideration of the randomness of the load and the fluctuation and randomness of the output of the distributed generation, a new reconfiguration model of the distribution network with microgrid is established in this paper. Dynamic reconstruction is not a simple superposition of reconstructions in sub-periods. The influence of the number of switching operations on the operation mode between adjacent sub-periods and the overall optimality of the objective function must also be considered. The mathematical probability models of distributed generations and load are constructed in this paper. The dynamic reconfiguration is completed on the basis of probabilistic power flow. The objective function is calculated by stochastic power flow. The optimization algorithm is applied to the reconstruction process. The simulation results verify the effectiveness of the proposed model and algorithm in dynamic reconstruction.
