    Opis:
    Cybercriminals during the COVID-19 coronavirus pandemic have redefined both their targets and the form of their cyberattacks. The increased dependence of people around the world on the Internet is driving increasingly bold hacking attacks. Business unit managers are forced to implement better and better security of data resources, which should be organized and at the same time characterized by confidentiality, integrity, and availability. The purpose of the article was to identify and analyse the impact of the COVID-19 pandemic on the cyber security of the business entity. In realizing the purpose of the article, the starting point was a theoretical introduction to cybersecurity. Then, based on the Cybercrime: Covid-19 Impact report developed by Interpol, it was indicated that the coronavirus pandemic has a very high impact on the cyber threat panorama. To analyse the actual market situation, the effects of the cyber-attack on CD PROJEKT Capital Group were analysed.

    Maritime Cyber Security
    Opis:
    Today’s shipping industry is largely digitalized and networked, but by no means immune to cyber attacks. As recent incidents show, attacks, particularly those targeting on the misleading of navigation, not only pose a serious risk from an economic perspective when disrupting maritime value chains, but can also cause collisions and endanger the environment and humans. However, cyber defense has not yet been an integral part of maritime systems engineering, nor are there any automated tools to systematically assess their security level as well-established in other domains. In this paper, we therefore present a holistic BRidge Attack Tool (BRAT) that interactively offers various attack implementations targeting the communication of nautical data in maritime systems. This provides system engineers with a tool for security assessments of integrated bridge systems, enabling the identification of potential cyber vulnerabilities during the design phase. Moreover, it facilitates the development and validation of an effective cyber defense.

    Opis:
    Okres XXI wieku jest bezprecedensowy, jeżeli chodzi o rozwój w obszarze technologii. Użytkownicy cyberprzestrzeni muszą proaktywnie korzystać z praktyk związanych zachowaniem bezpieczeństwa, aby były one realnie skuteczne i odczuwalne. Celem artykułu było zbadanie wpływu dynamicznie postępującej cyfryzacji na cyberbezpieczeństwo systemów teleinformatycznych oraz świadomości ich użytkowników w tym zakresie. Przeprowadzone badania jednoznacznie wskazują, iż istnieje kilka obszarów cyberbezpieczeństwa, w których należałoby poczynić kroki mające na celu zwiększenie świadomości społeczeństwa. Główny obszar stanowi uświadomienie, że każdy użytkownik Internetu może być potencjalnym celem ataku cybernetycznego. Kolejnym istotnym obszarem, który został uwidoczniony podczas analizy odpowiedzi na pytania ankietowe, jest rażąca polityka zarządzania hasłami praktykowana przez użytkowników Internetu. W artykule wykorzystano następujące metody i techniki badawcze: metody ankietowe, metody indukcji jako formy przechodzenia od szczegółu do ogółu, metodę dedukcji jako formę uogólniającą i wnioskową, analizę literatury oraz danych statystycznych. Poruszana tematyka w opracowaniu wskazuje na konieczność prowadzenia oraz rozwoju badań nad sposobem, w jaki społeczeństwo reaguje na zmiany zachodzące w cyberprzestrzeni.
    The period of the 21st century is unprecedented in terms of developments in technology. Users of cyberspace must proactively use security preservation practices to be realistically effective and noticeable. The purpose of the article was to study the impact of rapidly advancing digitization on the cyber security of ICT systems and the awareness of their users in this regard. From the research, it was clear that there are several areas of cyber security in which steps should be taken to increase public awareness. The main area is awareness that any Internet user can be a potential target of a cyber attack. Another important area that was highlighted during the analysis of survey responses is the blatant password management policies practiced by Internet users. The following research methods and techniques were used in the article: survey method, induction method as a form of going from the particular to the general, deduction method as a form of generalization and inference, analysis of literature and statistical data. The topics discussed in the article indicate the need to conduct and develop research on how society responds to changes in cyberspace.

    GNSS PRN Pseudorange Code
    Opis:
    Pseudo-Random Noise (PRN) Gold code was selected for utilisation as the Global Navigation Satellite System (GNSS) pseudo-range measurement code sequence. Recent studies revealed a potential security vulnerability issue due to the Gold PRN code utilisation in a GNSS-related cyber-attack known as GNSS spoofing. Here a PRN code construction method based on chaotic-form logistic map is proposed as an alternative to the existing Gold code practice. Dubbed Chaotic Ranging Code (CRC), is a PRN code generation method that generates ranging code with orthogonal properties as good as, if not better, then those of the Gold PRN code, while assuming the encryption embedded in the proposed CRC code provides improved GNSS information security.

    Opis:
    The technology that has evolved with innovations in the digital world has also caused an increase in many security problems. Day by day the methods and forms of the cyberattacks began to become complicated, and therefore their detection became more difficult. In this work we have used the datasets which have been prepared in collaboration with Raymond Borges and Oak Ridge National Laboratories. These datasets include measurements of the Industrial Control Systems related to chewing attack behavior. These measurements include synchronized measurements and data records from Snort and relays with the simulated control panel. In this study, we developed two models using this datasets. The first is the model we call the DNN Model which was build using the latest Deep Learning algorithms. The second model was created by adding the AutoEncoder structure to the DNN Model. All of the variables used when developing our models were set parametrically. A number of variables such as activation method, number of hidden layers in the model, the number of nodes in the layers, number of iterations were analyzed to create the optimum model design. When we run our model with optimum settings, we obtained better results than related studies. The learning speed of the model has 100\% accuracy rate which is also entirely satisfactory. While the training period of the dataset containing about 4 thousand different operations lasts about 90 seconds, the developed model completes the learning process at the level of milliseconds to detect new attacks. This increases the applicability of the model in real world environment.

    Opis:
    Analysis of modern interstate conflicts, trends in the development of forms of warfare. It is shown that confrontation is characterized by various forms, is hidden in nature and is carried out mainly in the political, economic, informational and other spheres. It is proved that a significant part of hybrid wars are information operations used for the destructive impact on society, commercial activities, politics and economics using information and communication space and technologies. The article expresses the need to create a theoretical basis for combating cyber attacks in special telecommunication systems as an integral part of the national security of the state. The development of methods for hiding information as well as providing information during video streaming and images in networks is underway. The basic calculations are given at the initial stages of information hiding and methods for ensuring the latent transfer of data in telecommunication systems.
    W artykule dokonano analizy współczesnych konfliktów międzypaństwowych oraz kierunków rozwoju form walki zbrojnej. Pokazano, że konfrontacja charakteryzuje się różnymi formami, jest ukryta w naturze i prowadzona jest głównie w sferze politycznej, gospodarczej, informacyjnej i innych. Udowodniono, że znaczna część wojen hybrydowych to operacje informacyjne wykorzystywane do destrukcyjnego oddziaływania na społeczeństwo, biznes, politykę i ekonomię, wykorzystujące informacyjno-komunikacyjną przestrzeń i technologię. W artykule wyrażono potrzebę stworzenia teoretycznej podstawy zwalczania cyberataków w specjalnych systemach telekomunikacyjnych jako integralnej części bezpieczeństwa narodowego państwa. Opracowano metodę ukrytej informacji, a także dostarczania informacji w przesyłaniu strumieni wideo i obrazów w sieciach. Podstawowe obliczenia są podane na początkowych etapach ukrywania informacji i metod zapewnienia bezpieczeństwa cybernetycznego w systemach telekomunikacyjnych.

    Opis:
    The maritime industry is undergoing a rapid evolution through the introduction of new technology and the digitization of existing services. At the same time, the digital attack surface is increasing, and incidents can lead to severe consequences. This study analyses and gives an overview of 46 maritime cyber security incidents from the last decade (2010-2020). We have collected information from open publications and reports, as well as anonymized data from insurance claims. Each incident is linked to a taxonomy of attack points related to onboard or off-ship systems, and the characteristics have been used to create a Top-10 list of maritime cyber threats. The results show that the maritime sector typically has incidents with low frequency and high impact, which makes them hard to predict and prepare for. We also infer that different types of attackers use a variety of attack points and techniques, hence there is no single solution to this problem.

    Opis:
    The Covid-19 pandemic brought a problem related to the inability to timely update security systems on ships during a voyage and the need to encrypt data stored in ship information systems (SISs) and shipping company information systems. The analysis of new types of worldwide cyberattacks showed that they were set off by an increase in the use of remote-controlled autonomous technologies and a spread of telework. It was proved that on ships: a) there are no cybersecurity specialists; b) there is no means of identification of cyber threats and no response plans; c) there is a lack of cybersecurity training for crews; d) encryption of confidential ship data is barely used; e) crew is a vulnerability factor in ship's security. The analysis of cyber incidents allowed us to develop a basic response plan to protect ship control systems. It was demonstrated that the basic plan can be continuously updated and improved in accordance with: a) the real state of ship systems; b) the results of performance analysis of crew actions; c) the emergence of new types of cyberattacks. To improve the security of confidential data in ship information networks theoretical framework for the development of encrypted data search engines with the identification of “dangerous” keywords for the ship information systems (SISs) was proposed. A data exchange protocol, basic requirements for SISs, and an algorithm for detecting “dangerous” keywords in messages were developed. A test search engine on encrypted data was presented, and the main components of the system were highlighted. The functionality of the system was experimentally proved, and the accuracy and speed of search on encrypted data were determined.

    Opis:
    Ships, ports and offshore facilities are increasingly becoming dependent on modern information and opera-tional technology. Cyber incidents on ships can create disruptions of critical systems that cause problems for the ship’s safe operation. Therefore, the shipowners must be prepared to cope with rising cyber threats. In or-der to prevent cyber incidents happening on ships and in the companies, essential steps must be taken on the management level. This paper introduces results of two surveys on cybersecurity and cyber awareness carried out in between 2017 – 2019 among the shipping companies operating in Estonia. Feedback was received from 12 shipowners out of 19 and the results show that at least 7 organisations had been the victims to different types of cyberattacks. The results indicate that shipowners are not paying enough of attention to potential cyber threats and education of their employees. Finally, the paper proposes cyber risk mitigation means for the shipowners.

    Opis:
    As a result of the last decades development of technology and increased connectivity of maritime vessels, the need for maritime cyber security is undoubtedly present. In 2017, IMO officially recognized “… the urgent need to raise awareness on cyber threats and vulnerabilities to support safe and secure shipping, which is operationally resilient to cyber risks”. Thus, Maritime Cyber Resilience is seen as key by IMO in the improvement of the maritime cyber security. It is assumed that human error is the cause of more than half successful cyber-attacks. If technology somehow fails, in example because of a cyber threat, the human is expected to handle the problem and provide a solution. It is therefore necessary to focus on the human aspect when considering maritime cyber threats. This paper aims to provide a working definition of “Maritime Cyber Resilience”. Further, the paper argues why the human should be a focus of study, as the human is at the sharp edge in a potential maritime cyber emergency.

    Opis:
    In recent years, various types of commerce including transport have suffered significant damage and costs due to cyber-attacks. The geographic scope of freight transportation has no boundaries, attacks can be launched almost anywhere there is an Internet connection. Therefore, there is no immunity from the failure of computer systems and information of delivery processes in the networks of organizations and companies engaged in maritime transportation. In addition, while the consequences of cyber-attacks on major shipping lines and ports, as well as the digital systems of logistics companies, can be comprehensively analyzed, the vulnerability of ships remains insufficiently studied. This paper offers an analysis of the risks in the field of maritime freight transport and the main factors of influence such as digitization on the safety of the transport process. The basic threats to the information system of the ship are defined and the techniques of risk analysis for the ship information security is proposed.
