Opis:
Cybersecurity has benefitted from Artificial Intelligence (AI) technologies for attack detection. However, recent advances in AI techniques, in tandem with their misuse, have outpaced parallel advancements in cyberattack classification methods that have been achieved through academic and industry-led efforts. We describe the shift in the evolution of AI techniques, and we show how recent AI approaches are effective in helping an adversary attain his/her objectives appertaining to cyberattacks. We also discuss how the current architecture of computer communications enables the development of AI-based adversarial threats against heterogeneous computing platforms and infrastructures.

Opis:
Infrastruktura transportu kolejowego zapewnia codzienny przewóz dużej liczby osób i ładunków. Znaczenie kolei pod względem zapewnienia sprawności obsługi na danym obszarze czyni z niej infrastrukturę krytyczną. Obserwuje się istotny rozwój wykorzystania technologii informatycznych na kolei, podobnie jak we wszystkich innych branżach. Z tego względu zarządzanie koleją, jako systemem fi zycznym, należy zastąpić zarządzaniem koleją, jako systemem cyberfi zycznym. Infrastruktura kolejowa jest narażona na znaczące ataki zarówno w przestrzeni fi zycznej, jak i w cyberprzestrzeni. Artykuł jest poświęcony zarządzaniu sieciami komunikacyjnymi, służącymi do transmisji danych i partycjami, rozumianymi jako logicznie wydzielone zasoby informatyczne (służące do przetwarzania danych), wykorzystywanymi na potrzeby transportu kolejowego. Systemowo, wielopoziomowe, bezpieczne i niezależne (ang. System Multiple Independent Levels of Security – MILS) przetwarzanie danych spełnia wysokie wymagania dotyczące bezpieczeństwa systemu. MILS jest niezawodną architekturą bezpieczeństwa opartą na koncepcji separacji i kontrolowanego przepływu danych. W artykule opisano możliwości wykorzystania platformy MILS w systemie teleinformatycznym i systemie sterowania ruchem kolejowym.

Opis:
In this paper we present current key challenges with respect to Critical Infrastructure Protection and to their resiliency. As our world becomes more and more interconnected via open networks with the cyberspace, many new challenges arise. Therefore, we frame the problem within three distinctive domains: real world natural events, human (organisational and legal), and cyber one. Within our analysis we present how current technologies, tools and methodologies can be used to address certain problems within those domains. Moreover, we stress the fact that there is a limited number of initiatives that aim at proposing the holistic (all hazard) approach addressing all the domains at once.

Opis:
The work is devoted important issues of the management in maritime critical infrastructure of functional safety analysis, in particular the safety integrity level (SIL) verification of safety functions to be implemented within the distributed control and protection systems with regard to cyber security aspects. A method based on quantitative and qualitative information is proposed for the SIL (IEC 61508, 61511) verification with regard of the evaluation assurance levels (EAL) (ISO/IEC 15408), the security assurance levels (SAL) (IEC 62443), and the number of protection rings described in the Secure Safety (SeSa-SINTEF) methodology. The proposed approach will be composed of the following items: process and procedure based safety and cyber security management, integrated safety and security assessment of industrial control system (ICS) of the maritime critical infrastructure. Proposed methodology is illustrated on case study that based on the part of installation critical maritime infrastructure.

Opis:
The model is developed for the intellectualized decision-making support system on financing of cyber security means of transport cloud-based computing infrastructures, given the limited financial resources. The model is based on the use of the theory of multistep games tools. The decision, which gives specialists a chance to effectively assess risks in the financing processes of cyber security means, is found. The model differs from the existing approaches in the decision of bilinear multistep quality games with several terminal surfaces. The decision of bilinear multistep quality games with dependent movements is found. On the basis of the decision for a one-step game, founded by application of the domination method and developed for infinite antagonistic games, the conclusion about risks for players is drawn. The results of a simulation experiment within program implementation of the intellectualized decision-making support system in the field of financing of cyber security means of cloudbased computing infrastructures on transport are described. Confirmed during the simulation experiment, the decision assumes accounting a financial component of cyber defense strategy at any ratios of the parameters, describing financing process.

Opis:
The majority of operations, as well as the physical and chemical processes, which take place on offshore Natural Gas installations are controlled by computer systems. These computer systems are vulnerable to cyber-attacks. If successful, such attacks can have disastrous and far-reaching consequences, including human casualties, large-scale pollution, and immense financial cost. In this paper we identify one possible way that an attacker can inflict material damage, by altering the parameters of the gas hydrate inhibition system. The formation of gas hydrates can completely halt operations for a prolonged period of time, could damage equipment, and directly endanger human lives. To raise the level of protection we propose the implementation of two lines of defense the second based on machine learning algorithms. Appreciating the sophistication of attacks, the inherent risks and complexity of multi-billion offshore energy assets we highlight the need for further research intended to address safety loopholes.

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.
