Domino effects in the critical infrastructure
KUBELKA, Václav
The title of thesis is Domino effects in critical infrastructure and sets the objective to analyse the interaction between the representatives of individual critical infrastructure sectors. In case of failure in one sector, which would cause a domino effect and subsequently limited functionality or a failure in other sectors, the consequences for the population and the entire affected area would be enormous. This reason, as well as general topicality of this problem led me to focus my thesis on the area of critical infrastructure. Probably the most feared is power failure, which currently occurs very often and sometimes affects areas larger than cities, regions, and even states. Fortunately, all infrastructure representatives are usually best prepared for this kind of failure, and therefore its start and a short-term effect have practically no significant impact on their normal functioning. But for longer exposure exact consequences cannot be estimated because it depends on specific circumstances around individual representatives. The thesis is divided into several parts. The theoretical part, which is further subdivided, includes three chapters concerning critical infrastructure. The chapter setting the fundamental terms, which are used further in the thesis, enables to understand the inclusion of critical infrastructure. The historical development of the critical infrastructure and its position from the point of view of the European Union and also of the Czech Republic is also mentioned in the theoretical part. Finally, there are itemized and characterized individual critical infrastructure sectors. Very important questions dealing witch the protection of the critical infrastructure are discussed at the end of the theoretical part. It is important components involved in it are mentioned there, as well as various procedures supporting the effectivity, according to several publications. The practical part is also divided into chapters. The first part concerns interviews with specialists representing each sector of the critical infrastructure. Each of these representatives was asked about the effect of possible failures in other sectors that may arise in these situations. The question is whether the sectors tend to be influenced and thus to cause a domino effect, which could even result in the collapse of the companies represented by them. These interviews are then written in an adapted form. To see the interview data more easily, they are processed into tables according to the individual sectors of critical infrastructure and then commented.
