In today’s turbulent and complex times, the importance of the functional security and continuity of critical infrastructure (CI) is of particular importance. The Industry 4.0 (I4.0) toolset contains many technologies that support CI or are an integral part thereof. The purpose of this paper is to examine the relationship between CI and I4.0. The goal will be achieved by (1) conducting a systematic literature review using VOSviewer, (2) identifying leading research topics using Latent Dirichlet Allocation, (3) mapping the results obtained and identifying possibilities for further research. Web of Science, Scopus, and a set of specific keywords were used to select peer-reviewed papers presenting evidence of the considered connections. Selected clusters and topics were used to build a reference framework formed by relations between CI and I4.0. The results revealed that despite the popularity of both issues, studies examining the mutual relations between the same are lacking. The added value of the article is that it organizes the knowledge related to relations between I4.0 and CI, and indicates the research areas that require further scrutiny. It is the first comprehensive literature review focusing specifically on CI & I4.0.

The purpose of the presented research was to determine the effectiveness and sufficiency of measures put in place to protect the business continuity of critical infrastructure (CI) and key services (KSs) during the COVID-19 pandemic. The wide variety of research conducted in the area of business continuity maintenance during the COVID-19 pandemic does not change the fact that there is still a research gap in this area, particularly in terms of issues related to CI and KS protection. A systematic review of scientific publications revealed the need for continued research into this topic given the fact that only 19 papers related to CI continuity and 8 directly to KS operators could be identified. Holistic and interdisciplinary research is particularly needed to organize and systematize the existing scientific knowledge on the subject, and in practical terms, help organizations and institutions to better prepare for future continuity disruptions. A survey conducted between March and May 2021 among entities operating in Poland and classified as critical infrastructure operators as well as key service operators, subcontractors, and suppliers crucial to maintaining the continuity of critical infrastructure operations revealed that entrepreneurs, surprised by the speed and aggressive nature of the pandemic, mainly resorted to protective measures that were immediately available, standard solutions that did not require excessive financial and organizational effort. But in the face of long-term pandemic threat, such measures may no longer be sufficient, so it is important to intensify research into those precautions that require readaptation of work organization and organizational processes to protect key workers, increase supply chain resilience, and protect the work process.

Business Intelligence technology for over 20 years is the market leader in analytical processing of data. As numerous market researches demonstrate Business Intelligence has substantial affect on global competitiveness of enterprises and on the stability of their position in the market, which is particularly important in times of economic downturn. Although main users of this technology are large companies and corporations, software vendors are still looking for solutions that are also available for the SME (Small and Middle Enterprises) sector and non-profit enterprises. One option available recently is possibility to use Cloud Computing environment. The article considers the opportunities and risks posed by the organization of Cloud Business Intelligence system on the example of using it in SME sector.

Critical infrastructure (CI) business continuity is fundamental in today’s turbulent times. The new trend is the reference to essential services (ES). This paper aims to identify lead topics in the ES area and analyze actions to provide ES business continuity. The goal will be achieved by (1) identifying leading research topics using Latent Dirichlet Allocation, (2) conducting a systematic literature review using VOSviewer, (3) mapping the results obtained, and identifying possibilities for further research. Web of Science, Scopus, and specific keywords were used to select peer-reviewed papers discussing the ES issue. The results showed that, despite the importance of the ES issue, there are few publications related to the business continuity of ES. The work focuses on the relevance of ES to individual entities such as companies, cities, municipalities, and countries. There are also isolated works on ES security, but mainly in cybersecurity. The added value of the article is that it organizes the knowledge related to leading topics in the ES area from a Business, Management, and Accounting perspective and indicates the research areas that require further scrutiny. It is the first comprehensive literature review focusing specifically on ES.

This article presents a synthesis of knowledge about safety management procedures for critical infrastructure (CI) in the context of risk management theory and the provisions of the Polish law on emergency management of 26 April 2007. In this paper, the inadequacy of the accepted procedures at present is highlighted, as well as their continuous improvement and adaptation to prevailing political, legal, social and economic conditions. It proposes using the concept of scenario approach and situational management approach and technique analysis of interconnected decision areas (AIDA) and casebased reasoning (CBR) to develop integral situational resource model CI. The considerations presented in this paper lead to a proposed a new method for predicting, preventing and responding to emerging crises within the CI.
