Security Information Sharing for the Polish Power System
PublikacjaThe Polish Power System is becoming increasingly more dependent on Information and Communication Technologies which results in its exposure to cyberattacks, including the evolved and highly sophisticated threats such as Advanced Persistent Threats or Distributed Denial of Service attacks. The most exposed components are SCADA systems in substations and Distributed Control Systems in power plants. When addressing this situation...

Approach to security assessment of critical infrastructures' information systems
PublikacjaThis study presents an approach to the security assessment of the information systems of critical infrastructures. The approach is based on the faithful reconstruction of the evaluated information system in a computer security laboratory followed by simulations of possible threats against the system. The evidence collected during the experiments, stored and organised using a proprietary system InSAW, may later be used for the creation...

Data Model Development for Security Information Sharing in Smart Grids
PublikacjaThe smart grid raises new security concerns which require novel solutions. It is commonly agreed that to protect the grid, the effective collaboration and information sharing between the relevant stakeholders is prerequisite. Developing a security information sharing platform for the smart grid is a new research direction which poses several challenges related to the highly distributed and heterogeneous character of the grid. In...

Security Requirements and Controls for Incident Information Sharing in the Polish Power System
PublikacjaAmong the strategies of protecting information assets of the power system, sharing of information about current cybersecurity incidents between energy operators appears to be a prerequisite. Exchange of information leads to the effective detection of attacks and exploited vulnerabilities as well as the identification of countermeasures. This paper presents the results of continuation of our works on developing a secure and efficient...

Relating Information Culture to Information Policies and Management Strategies
PublikacjaBusiness and information managers have struggled to meet several challenges in aligning information strategies and business cultures. The consequences of a misalignment or misfit of strategy and culture are well known in business literature, and better guidance on how to better align strategy and culture is needed. This means expanding the puzzle to align business and information cultures, align business and information strategies,...

What is information?
PublikacjaPrzedstawiono zarys metodologii konstrukcji miar informacyjnych opartej na sterowaniu zdarzeniowym. Podejście takie umożliwia jawne uwzględnianie wpływu kontekstu, kryterium użyteczności i protokołu postępowania na ilość informacji. Podano szereg przykładów obejmujących systemy rozproszone, transmisję danych, środowiska niekooperacyjne i in. wraz z oceną wynikowej przepustowości. Wskazano dalsze kierunki badań, m. in. w kierunku...

What is information?
PublikacjaPojęcie informacji było dotąd kwantyfikowane głównie w terminach statystycznych, dając początek shannonowskiej teorii informacji i zasad cyfrowej transmisji danych. Współczesne systemy komunikacyjne łączące skomplikowane, inteligentne i autonomiczne podmioty wymagają nowego spojrzenia na miary informacji, uwzględniającego kontekst i semantykę przekazu oraz racjonalne działania podmiotów. W niniejszym eseju zaproponowano podejście...
