In the article, a modification of Formal Model of Risk Analysis FoMRA was proposed. The Modified FoMRA (1) method takes into account the guidelines of ISO/IEC 27001 and ISO/IEC 27005 standards. The applied modification and abstraction by resources and security controls (also called countermeasures) significantly shortened the time of risk weight calculation in comparison with the MEHARI method. An attempt was also made to further reduce the time of risk analysis using agents collecting information and data from various network nodes, from operating systems and devices, and additional agents containing information on reports on security procedures, security services, security management and organizational activities related to the information systems (maintenance, insurance, outsourcing contracts, etc.) and transfer it to the local FoMRA1 database. The obtained results indicate that the proposed method together with agents installed in various nodes enable a quick reaction to the system threats and prevention of their impacts (quasi-real-time security monitoring system)

In a connected and uncertain world, where almost two thirds of the world's population are now online, the integration of digital tools in the social and economic context is becoming a priority and an imposed choice for any organization. As a result, the strategic position of the Information System (IS) in these organizations is necessarily linked to performance. The creation of added value or net benefits through the use of these platforms becomes an ultimate and strategic objective for any organization. This study evaluates the success of the information system (IS) for electronic payment of port fees. From a quantitative approach of a hypothetico-deductive nature and using partial least squares structural equation modeling (PLS-SEM), we found that the success of the IS implies a quality of the electronic payment system, as well as the information produced influences the use and satisfaction of the users and finally these last two findings impact the individual and organizational performance of the organizations. (Net benefits).

Background: The purpose of this study is to create a theoretical framework for analyzing the causal relationship between supply chain management practices and firm performance, in the FMCG sector of Pakistan. A quantitative research approach was adopted, in which a multi-item scale Web-based survey using a structured online questionnaire was utilized to collect the primary data. A total of 232 questionnaires were collected from a sample of Karachi-based FMCG companies in Pakistan. Confirmatory Factor analysis and internal consistency were used to test the reliability and fitness of the measurement model, and structural equation modeling-SEM was employed to test the proposed hypotheses. Empirical findings reveal that there is a significant positive relationship between SCM practices and firm performance. However, the results of the individual-level analysis of SCM practices appear to vary from practice to practice. Of various SCM practices, supplier strategic partnership SSC with the highest beta value (i.e., ß = 0.488; t-value = 32.381; p _ 0.000) was found to have the greatest impact on firm performance, followed by information sharing customer relationship, and finally the outsourcing. This study will guide supervisors with a more in-depth understanding of SCM practices and their potential contribution to firm performance. The findings also encourage managers to place supplier strategic partnerships and information systems on high priority, on both inter-firm and intra-firm relationships, as prerequisites for achieving superior firm performance. The propositions and results of the study provide managers with guidelines about effective management of upstream supply chain networks and awareness of the potential synergies that arise from suppliers and the information system. This article further enriches the literature in an evolving area of supply chain management practices. Two key factors facing supply chain managers and scholars are addressed, and establish their ability to drive firm performance.

Modern integrated information and telecommunication systems are upgraded on a continuous basis. Such systems contain both new and old components. The approaches to developing individual components of access control systems are different in the majority of cases. As a rule, modernization of outdated but efficient systems that have been operating without any failures for long periods of time is economically unfeasible. Such an approach requires that different subsystems function based on shared data. This necessitates the coordination of various access control systems in order to ensure proper information security levels. This article examines how joint functioning of various versions of access control systems deployed in IT and telecommunication spheres may be achieved at the stage of their modernization. Potential ways in which information flows may bypass the security policies of one of the access control systems concerned are determined. The authors discuss traditional access control models. For role-based and thematic access control models, specific hypotheses are formulated to comply with security policies when different versions of access control systems work together. The structure of the model assuming that different versions of access control systems operate jointly has been developed. Based on the model, the necessary and sufficient conditions are determined under which unauthorized information flows are prevented. The security theorem for the joint functioning of different versions of access control systems is presented and proved. The results of the study showed that the methodological basis for coordinating access control models applicable to information and telecommunication systems undergoing modernization consists in observing, separately, the equality of information flows between shared objects in each of the versions of the access control systems. The approaches developed in this article can be extended to combined access control systems.

Soldiers of the Territorial Defense Forces (TDF) (Polish name: Wojska Obrony Terytorialnej - WOT) have been supporting medical services and local government entities in the fight against COVID-19 for over 2 years. During the pandemic period, as the number of cases increased, so did the number of operations carried out by TDF soldiers. The considerations presented in the article are related to the territorial defense forces, and the aim of research is to check, verify, and evaluate the status of involvement of TDF in supporting public administration, sanitation and emergency services in the fight against the Sars-CoV-2 coronavirus pandemic. The research hypothesis was adopted, which assumed that the IT application implemented in the Territorial Defense Forces supporting the activities of the Territorial Defense Forces would enable universal access by entities of the non-military system applying for TDF assistance and would shorten the time needed to provide assistance. The implementation of the above-outlined aims of the article required answers to research questions: To what extent did the "Pomoc WOT" IT platform support the public administration, sanitary and emergency services in the fight against the pandemic? The following empirical research methods were applied: the method of analysis and criticism of the literature of the research subject and statistical methods concerning non-military actors, to which the soldiers of the TDF provided support in the fight against COVID-19. From among theoretical methods, the following were used: analysis, synthesis, and inference methods. Scientific research results. More than 1,000 TDF soldiers are deployed every day to carry out the tasks in the fight against the pandemic, providing support in dozens of hospitals and sanitary stations, vaccination points, as well as blood donation and transfusion centers. "WOT Pomoc" application implemented in the TDF Command was developed to facilitate submission, without physical contact, of support requests for TDF soldiers. Through its use, each of the state's non-military system entities eligible to receive military support has the ability to log into the application and submit a request for support. This eliminated the need for multi-level approval of requests, from the voivode up to the Minister of Defense. Since the launch of the application, all the activities related to submitting requests are done automatically, without the need to perform additional actions, and information about the approval of the request is transferred directly to the appropriate brigade commander of the Territorial Defense Forces.

Semantic checking of railway infrastructure information support data is one of the ways to improve the consistency of information system data and, as a result, increase the safety of train traffic. Existing ontological developments have demonstrated the applicability of description logic for modelling railway transport, but have not paid enough attention to the data resources structure and the railway regulatory support. In this work, the formalization of the tabular presentation of data and the rules of railway transport regulations is carried out using the example of a connection track passport and temporary speed restrictions using ontological means, data wrangling and extraction tools. Ontologies of the various formats data resources and railway station infrastructure, tools for converting and extracting data have been developed. The semantic checking of the compliance of railway information system data with regulatory documents in terms of the connection track passport is carried out on the basis of a multi-level concretization model and integration of ontologies. The mechanisms for implementing the constituent ontologies and their integration are demonstrated by an example. Further research includes ontological checking of natural language normative documents of railway transport.

In this paper a modification of Mike Cohn's test pyramid is described for adaptation during testing in distributed information processing systems which allows expanding the possibilities of testing and applying the features of such systems. Recommendations for further use of the mechanisms of modified Mike Cohn's pyramid are developed. The method of testing the user interface software of the nodes of a distributed system was improved to differ from the existing techniques by including a mechanism of simulation of its operation to allow testing of individual components of the system interface. It is shown that in comparison with end-to-end testing of user interfaces the advantages of using the mechanisms of user interface test simulators allow reducing the time spent on testing any UI service. The time is reduced by decreasing the number of simultaneous user interface services. With a small number of nodes, end-to-end testing of user interfaces is faster than simulation testing of the same user interfaces. As the number of nodes increases, the time required to test the services of a distributed system by simulation tests becomes shorter than the time required to test the same system by a traditional method.

Nowadays Information Systems (IS) become more and more distributed, complex, and heterogeneous. Such nature of IS make them or their components a Black Box. Although classical software operates according understandable logic, modern complex software often shows non-determinism in its operation. Artificial Intelligence (AI) based on Artificial Neural Networks (ANN) is an example of such systems. This paper considers IS architecture consisting of 4 components, one of which represents non-determinism as an "Machine Intuition". The architecture is derived from 3-tier computer architecture and based on psychological findings. This approach allowed building a simple and user/developer friendly model. Practical value of the architecture is concluded in ability to better understand, design, and develop the IS containing units with non-deterministic behavior, deal with AI overfitting, underfitting, and threat problems. Architecture and principles represented in this paper can be applied not only to AI/ANN but different IS types.

The specificity of tool provisioning is conditioned using tooling, the quantity of which exceeds the nomenclature of the manufactured goods considerably. Therefore, for modern enterprises, first-priority issues are harmonizing the processes of tool provisioning systems, increasing the level of the reaction of this system to changes, obtaining operational control over the production system, and, thus, improving the efficiency of the production process. In this paper, a mathematical model of decision-making based on determining the optimal strategy for the process flow was proposed to improve the efficiency of the information system for quality management of tool provisioning. It is suggested to use the sustainable development factor of information system for quality management of tool provisioning to make decisions about the path of the tooling process, which considers the requirements of international standards for management systems (ISO 9001, ISO 45001, etc.). This model is based on the application of graph optimization theory, fuzzy logic, and Markov chains. The use of this model is universal and will increase the validity of operational management decisions, increase productivity, reduce resource dependency, and, therefore, reduce the costs of tool provisioning, which directly affects the cost of production and competitiveness of the enterprise as a whole.

Currently, the processing and transmission of the vast amount of information accompanying material flows are performed using modern computer and telecommunications technologies. However, the achieved results differ depending on the company's preparation to receive a specific information technology (IT). One of the main problems, that need to be solved before starting the implementation of an integrated management system, is to set up all the rules for indexing and labeling information contained in databases. This issue is of key importance because it unifies records in databases making them unique based on their features and/or parameters, furthermore it enables qualification and selection of information according to specific criteria. Moreover, it facilitates data accumulation process. The research conducted on the content of databases showed items inactive for over 5 years, in an amount of 28% to 45%, in the majority of the surveyed enterprises. This situation requires database cleaning and only active index files can be used for generating a new database. The database cleaning process should aim to organize information in current materials management databases for present data processing needs, furthermore it should also prepare existing resources for transfer to the new IT system

Aktualnie przetwarzanie i przesyłanie ogromu informacji towarzyszących przepływom materialnym realizowane jest za pomocą nowoczesnych technologii komputerowych i telekomunikacyjnych. Jednak uzyskiwane efekty są bardzo różne w zależności od przygotowania przedsiębiorstwa do przyjęcia określonej techniki informatycznej. Jednym z zasadniczych problemów, z jakimi należy uporać się przed rozpoczęciem wdrożenia zintegrowanego systemu zarządzania, jest ustalenie wszelkich zasad indeksowania i znakowania informacji zawartych w bazach danych. Zagadnienie to ma kluczowe znaczenie, bowiem z jednej strony ujednolica zapisy informacyjne w bazach i czyni je unikalnymi ze względu na cechy czy parametry, z drugiej zaś, umożliwia selekcjonowanie i wybieranie informacji według określonych kryteriów oraz agregowanie danych. Wykonane badania zawartości baz danych wykazały, że w większości badanych przedsiębiorstw występowały pozycje nieaktywne od ponad 5 lat, w ilości od 28 do 45%. Sytuacja taka wymaga oczyszczenia bazy danych i dopiero pliki aktywnych indeksów mogą być podstawą utworzenia nowej bazy materiałowej. Istotnym efektem tej operacji ma być z jednej strony uporządkowanie informacji w aktualnych bazach związanych z gospodarką materiałową dla bieżących potrzeb przetwarzania danych, z drugiej przygotowanie istniejących zasobów do migracji do nowego systemu informatycznego.
