The Impact

To comply with electric power grid automation strategies, new cyber-security protocols and protection are required. What we now experience is a new type of protection against new disturbances namely cyber-attacks. In the same vein, the impact of disturbances arising from faults or cyber-attacks should be surveyed by network vulnerability criteria alone. It is clear that the diagnosis of vulnerable points protects the power grid against disturbances that would inhibit outages such as blackouts. So, the first step is determining the network vulnerable points, and then proposing a support method to deal with these outages. This research proposes a comprehensive approach to deal with outages by determining network vulnerable points due to physical faults and cyber-attacks. The first point, the network vulnerable points against network faults are covered by microgrids. As the second one, a new cyber-security protocol named multi-layer security is proposed in order to prevent targeted cyber-attacks. The first layer is a cyber-security-based blockchain method that plays a general role. The second layer is a cyber-security-based reinforcement-learning method, which supports the vulnerable points by monitoring data. On the other hand, the trend of solving problems becomes routine when no ambiguity arises in different sections of the smart grid, while it is far from a big network’s realities. Hence, the impact of uncertainty parameters on the proposed framework needs to be considered. Accordingly, the unscented transform method is modeled in this research. The simulation results illustrate that applying such a comprehensive approach can greatly pull down the probability of blackouts.

Smart Grid Technology

An existing power grid is going through a massive transformation. Smart grid technology is a radical approach for improvisation in prevailing power grid. Integration of electrical and communication infrastructure is inevitable for the deployment of Smart grid network. Smart grid technology is characterized by full duplex communication, automatic metering infrastructure, renewable energy integration, distribution automation and complete monitoring and control of entire power grid. Wireless sensor networks (WSNs) are small micro electrical mechanical systems which are accomplished to collect and communicate the data from surroundings. WSNs can be used for monitoring and control of smart grid assets. Security of wireless sensor based communication network is a major concern for researchers and developers. The limited processing capabilities of wireless sensor networks make them more vulnerable to cyber-attacks. The countermeasures against cyber-attacks must be less complex with an ability to offer confidentiality, data readiness and integrity. The address oriented design and development approach for usual communication network requires a paradigm shift to design data oriented WSN architecture. WSN security is an inevitable part of smart grid cyber security. This paper is expected to serve as a comprehensive assessment and analysis of communication standards, cyber security issues and solutions for WSN based smart grid infrastructure.

With the increased investment and deployment of embedded computing and communication technologies in the power system – the smart grid vision is shaping up into a reality. The future power grid is a large cyber physical system (CPS) which is vulnerable to cyber security threats. Among the three major subsystems of a power grid – generation, transmission and distribution – this survey focuses on the transmission subsystem because most of the cyberization of the grid has been happening in this subsystem. This is due to the need for distributed measurement, monitoring and control to retain the stability, security, and reliability of power transmission system. Given the geographically dispersed generation facilities, substations, control centers, data concentrators etc., efficient data communication is required, and therefore large scale networking – either proprietary or leased – is happening. The goal of this paper is not to be comprehensive to include all efforts of securing the transmission system from cyber borne threats, but to provide a survey of various vulnerabilities, and countermeasures proposed by various research efforts. One of the focus area in this survey is the Phasor Measurement Units (PMUs) and Wide Area Measurement System (WAMS) technology – mostly due to our familiarity with the issues for this specific technology deployment – rather than any attempt to indicate that this is the most vulnerable technology in the transmission subsystem. Our hope is that this survey will familiarize any uninitiated reader with the issues and provide incentive to undertake systematic research programs to thwart cyber attacks on our national power delivery infrastructure.

Growing concern about healthcare information security in the wake of alarmingly rising cyber-attacks is being given symmetrical priority by current researchers and cyber security experts. Intruders are penetrating symmetrical mechanisms of healthcare information security continuously. In the same league, the paper presents an overview on the current situation of healthcare information and presents a layered model of healthcare information management in organizations. The paper also evaluates the various factors that have a key contribution in healthcare information security breaches through a hybrid fuzzy-based symmetrical methodology of AHP-TOPSIS. Furthermore, for assessing the effect of the calculated results, the authors have tested the results on local hospital software of Varanasi. Tested results of the factors are validated through the comparison and sensitivity analysis in this study. Tabulated results of the proposed study propose a symmetrical mechanism as the most conversant technique which can be employed by the experts and researchers for preparing security guidelines and strategies.

The smart grid has been using more and more power electronic devices as an improvement to the current electrical power system along with plug-and-play integration of alternating sources of power. It has adopted the latest wired/wireless technologies incorporated into electric devices for timely information flow, control and on-demand interaction with customers. So, smart grid is reliable, efficient, and user as well as environment friendly. The grid keeps on getting smarter with better availability of new materials, storage systems, and alternative sources of energy. Though, this paper encompasses all sectors of smart grid, not limited to, smart transmission line, smart distribution generation, smart storage, smart communication, cyber security, and environment friendliness, it has demonstrated the wireless prototype of remote interaction between the consumers and the utility company. In countries like Nepal where power grid infrastructure is limited mostly to cities and energy supply is far below its demand, there is a great potential for energy market growth having minimal barriers to renewables.

The Impact

As our daily lives and socioeconomic activities have increasingly come to depend on information systems and networks, the impact of disruptions to these systems and networks have also become more complex and diversified. In urban areas, where people, goods, money, and information are highly concentrated, the possibility of chain failures and confusion beyond our expectations and experience is especially high. The vulnerabilities in our systems and networks on have become the targets of cyber attacks, which have come to cause socioeconomic problems with increasing likelihood. To counter these attacks, technological countermeasures alone are insufficient, and countermeasures such as the development of professional skills and organizational response capabilities as well as the implementation of cyber security schemes based on public-private partnerships (PPP) at the national level must be carried out as soon as possible. In this JDR mini special issue on Cyber Security, I have tried to expand the scope of traditional cyber security discussions with mainly technological aspects. I have also succeeded in including non-technological aspects to provide feasible measures that will help us to prepare for, respond to, and recover from socioeconomic damage caused by advancing cyber attacks. Finally, I am truly grateful for the authors’ insightful contributions and the referees’ acute professional advice, which together make this JDR mini special issue a valuable contribution to making our society more resilient to incoming cyber attacks.
