Scada Systems

In the current age, cyber security is an essential element of any information system. A key aspect is in the critical information infrastructure, where information security has become a top priority for information and network security experts. The interoperability of an ICT infrastructure with other components of it is an important aspect of its life cycle. Because Supervisory Control and Data Acquisition (SCADA) systems form part of the critical infrastructure, their cyber protection is particularly important in strategically important industrial and infrastructure sites — power plants, refineries, oil pipelines, treatment plants, manufacturing facilities, communications and transportation infrastructures. Along with the advancement of technology, the increasing number of Scada devices available online, the vulnerability of the sectors controlled by them has also increased. In the world of Internet of things (everything), the end devices cause a new wave of possible vulnerabilities in SCADA. They become the new places for attacks and breaches trough wich the system may be accessed or even compromised. There are a number of critical infrastructures in the Community whose disruption or destruction would have significant cross-border implications for more than one sector as a result of the interdependence of interconnected infrastructures. Such European critical infrastructures have been established and launched under a common procedure developed by the European Commission, with security requirements assessed according to a common minimum approach. The present article exposes and examines the critical infrastructures of the European Union and Bulgaria. Trough presenting the structure of a Scada system the vulnerabilities and the various possibilities of attacking it were analised. As an example, a specific case based on trees has been considered, and the obtained results were summarized and visualized. The consequences were analized and respecctive conclusion was done.

Types Of Information

The rapid development of information and communication technologies has increased the vulnerabilities of various networks, systems and objects as well as made it much more difficult to ensure their reliable protection and security. All these factors have led to the fact that the world's leading countries have begun to pay considerable attention to cybersecurity and critical information infrastructure protection. However, the protection of various types of information with restricted access (in particular, confidential information) at critical infrastructure objects remains unexplored. With this in mind, the paper analyzes the existing approaches of the world's leading countries to the confidential information protection at critical infrastructure. The analysis revealed that today there are no comprehensive, multifunctional methods of protecting confidential information at critical information infrastructure. In addition, the classification of critical information infrastructure objects according to information security requirements is developed. This classification by determining the type of processing information, possible access modes and criticality category, allows to ensure unity of approaches to protection of these objects belonging to different types, including information systems, automated control systems and information-telecommunication networks.

The article discusses the competences and powers of the state authorities of the Russian Federation within their legal status in the field of ensuring the security of critical information infrastructure. Some functions and authorities in the field of information security have changed in a number of federal executive bodies. In particular, the Federal Security Service, on the basis of a presidential decree, is authorized to create a state system for detecting, preventing and eliminating the consequences of computer attacks on information resources of the Russian Federation. However, not all rights and obligations are enshrined; a number of powers cause the duality of the legal status of certain federal bodies of state power. The clarity and unambiguity of securing the rights and obligations of state bodies authorized in the field of information security are guarantees for effectively ensuring the security of important information infrastructure facilities.

Triboelectrostatic Separation

Background: The fly ash produced by coal-fired power plants is an industrial waste. The environmental pollution problems caused by fly ash have been widely of public environmental concern. As a waste of recoverable resources, it can be used in the field of building materials, agricultural fertilizers, environmental materials, new materials, etc. Unburned carbon content in fly ash has an influence on the performance of resource reuse products. Therefore, it is the key to remove unburned carbon from fly ash. As a physical method, triboelectrostatic separation technology has been widely used because of obvious advantages, such as high-efficiency, simple process, high reliability, without water resources consumption and secondary pollution. Objective: The related patents of fly ash triboelectrostatic separation had been reviewed. The structural characteristics and working principle of these patents are analyzed in detail. The results can provide some meaningful references for the improvement of separation efficiency and optimal design. Methods: Based on the comparative analysis for the latest patents related to fly ash triboelectrostatic separation, the future development is presented. Results: The patents focused on the charging efficiency and separation efficiency. Studies show that remarkable improvements have been achieved for the fly ash triboelectrostatic separation. Some patents have been used in industrial production. Conclusion: According to the current technology status, the researches related to process optimization and anti-interference ability will be beneficial to overcome the influence of operating conditions and complex environment, and meet system security requirements. The intelligent control can not only ensure the process continuity and stability, but also realize the efficient operation and management automatically. Meanwhile, the researchers should pay more attention to the resource utilization of fly ash processed by triboelectrostatic separation.

The Republic of Korea also suffered direct and indirect damages from the Fukushima nuclear accident in Japan and realized the significance of security due to the cyber-threat to the Republic of Korea Hydro and Nuclear Power Co., Ltd. With such matters in mind, this study sought to suggest a measure for improving security in the nuclear power plant. Based on overseas cyber-attack cases and attacking scenario on the control facility of the nuclear power plant, the study designed and proposed a nuclear power plant control network traffic analysis system that satisfies the security requirements and in-depth defense strategy. To enhance the security of the nuclear power plant, the study collected data such as internet provided to the control facilities, network traffic of intranet, and security equipment events and compared and verified them with machine learning analysis. After measuring the accuracy and time, the study proposed the most suitable analysis algorithm for the power plant in order to realize power plant security that facilitates real-time detection and response in the event of a cyber-attack. In this paper, we learned how to apply data for multiple servers and apply various security information as data in the security application using logs, and match with regard to application of character data such as file names. We improved by applying gender, and we converted to continuous data by resetting based on the risk of non-continuous data, and two optimization algorithms were applied to solve the problem of overfitting. Therefore, we think that there will be a contribution in the connection experiment of the data decision part and the optimization algorithm to learn the security data.

Concentrated Solar Power Plants

Concentrated solar power plants belong to the category of clean sources of renewable energy. The paper discusses the possibilities for the use of molten salts as storage in modern CSP plants. Besides increasing efficiency, it may also shift their area of application: thanks to increased controllability, they may now be used not only to cover baseload but also as more agile, dispatchable generators. Both technological and economic aspects are presented, with focus on the European energy sector and EU legislation. General characteristics for CSP plants, especially with molten salt storage, are discussed. Perspectives for their development, first of all in economic aspects, are considered.
