Varkey, Mariam, John, Jacob, S., Umadevi K..  2022.  Automated Anomaly Detection Tool for Industrial Control System. 2022 IEEE Conference on Dependable and Secure Computing (DSC). :1—6.
Industrial Control Systems (ICS) are not secure by design–with recent developments requiring them to connect to the Internet, they tend to be highly vulnerable. Additionally, attacks on critical infrastructures such as power grids and nuclear plants can cause significant damage and loss of lives. Since such attacks tend to generate anomalies in the systems, an efficient way of attack detection is to monitor the systems and identify anomalies in real-time. An automated anomaly detection tool is introduced in this paper. Additionally, the functioning of the systems is viewed as Finite State Automata. Specific sensor measurements are used to determine permissible transitions, and statistical measures such as the Interquartile Range are used to determine acceptable boundaries for the remaining sensor measurements provided by the system. Deviations from the boundaries or permissible transitions are considered as anomalies. An additional feature is the provision of a finite state automata diagram that provides the operational constraints of a system, given a set of regulated input. This tool showed a high anomaly detection rate when tested with three types of ICS. The concepts are also benchmarked against a state-of-the-art anomaly detection algorithm called Isolation Forest, and the results are provided.

In view of the problem that the health status and safety monitoring of the traditional intelligent home are mainly dependent on the manual inspection, this paper introduces the intelligent home-based remote monitoring system by introducing the Internet-based Internet of Things technology into the intelligent home condition monitoring and safety assessment. The system's Android remote operation based on the MVP model to develop applications, the use of neural networks to deal with users daily use of operational data to establish the network data model, combined with S3C2440A microcontrollers in the gateway to the embedded Linux to facilitate different intelligent home drivers development. Finally, the power line communication network is used to connect the intelligent electrical appliances to the gateway. By calculating the success rate of the routing nodes, the success rate of the network nodes of 15 intelligent devices is 98.33%. The system can intelligent home many electrical appliances at the same time monitoring, to solve the system data and network congestion caused by the problem can not he security monitoring.

With the continuously development of smart meter-reading technologies for decades, remote information collection of electricity, water, gas and heat meters have been realized. Due to the difference of electrical interfaces and communication protocols among various types of meters, communication modes of meter terminals are not so compatible, it is difficult to realize communication optimization of electricity, water, gas and heat meters information collection services. In addition, with the development of power consumption information acquisition system, the number of acquisition terminals soars greatly and the data of terminal access is highly concurrent. Therefore, the risk of security access is increasing. This paper presents a light-weighted security access scheme of power line communication based on multi-source data acquisition of electricity, water, gas and heat meters, which separates multi-source data acquisition services and achieve services security isolation and channel security isolation. The communication reliability and security of the meter-reading service of "electricity, water, gas and heat" will be improved and the integrated meter service will be realized reliably.
