The purpose of the theoretical part of the study was to find out how ransomware programs work and what kind of threats they pose. In addition, the detection and prevention of ransomware were presented. In addition to ransomware, modern backup and recovery methods and their use in recovering from a ransomware attack were investigated. In the empirical part of the study, recovery methods were studied in practice and the methods used in recovery were compared. The topic of the research is important because ransomware pose a constant and serious threat to all networked information systems. The literature review was conducted as a literature analysis, using existing research information. In the empirical section, recovery testing was carried out in an attempt to compare different recovery methods. In the theoretical part of the study, it was found that recovery from a ransomware attack is a complex entity and recovery plans should be included in the business continuity planning. The empirical sections of the study found how different recovery methods affect recovery time and thereby the ability of organizations to recover from a possible ransomware attack.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-05-24T10:04:03Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-05-24T10:04:03Z (GMT).
