April 12th, 2019, Communication Institute PhD student Rokas Grincevičius defended his dissertation, "Improvement of Cybersecurity Management Using Resilience Models in Organisations."

The PhD dissertation deals with cyber resilience perceptions.

There is a growing number of calls to increase systems’ resilience to cyber threats. However, there are no methodologies, which describe how these processes should be implemented. Therefore, the study clarified cyber resilience perceptions and outlined the main elements of cyber resilience in organisations.

The organisational cyber resilience to cyber threats was analysed in the context of several management levels, thus creating conditions for further cyber resilience processes analysis. In order to form a theoretical basis of the organisation's model of cyber resilience, a scientific literature analysis was conducted. Thereby methods of systematisation, synthesis, comparison and generalisation were applied. Conceptual modelling and visualisation methods were used to formulate the model. Qualitative empirical research was used to validate the model.

The methods used in the empirical research: expert interview, qualitative content analysis, and analysis of secondary source data.
