T\u00e4m\u00e4 tutkielma tarkasteli kriittisen infrastruktuurin teknologisia haavoittuvuuksia keskittyen erityisesti kiristysohjelmahy\u00f6kk\u00e4yksiin, kriittisen infrastruktuurin j\u00e4rjestelm\u00e4kokonaisuuksiin ja niiden v\u00e4listen yhteyksien luomiin riskeihin.

As the amount of notorious ransomware attacks on critical infrastructure increase, more rigorous analysis of the common vulnerabilities and the risks they create for critical infrastructure is needed. This thesis aimed to create a wide understanding of why and how these attacks should be addressed by answering the following research questions: \u201chow has current scientific literature recognized the risks of ransomware attacks on different systems used by critical infrastructure?\u201d and \u201cwhich systems are targeted in ransomware attacks on critical infrastructure?\u201d. By analysing these issues this thesis aimed to give a concrete example of how ransomware attacks tend to happen to the multiple technological systems modern critical infrastructure utilize in their daily operations, and how the increasing interconnectedness of these systems has affected the situation. This thesis found that modern critical infrastructure employs different kinds of systems with varying levels of security in their implementations. Previous attacks suggest that a system connected to the internet often makes critical infrastructure vulnerable to attack, even in situations where the connected system is not directly used in operational actions. Furthermore, we find that the interconnectedness of these systems creates risks that have been underappreciated when developing new technology aimed at increasing efficiency.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2024-06-17T09:46:55Z\r\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-06-17T09:46:55Z (GMT).
