Windows 10 is one of the most used operating systems and as cyber threats become more prevalent to organisations and individuals this study offers knowledge about how to leverage group policy in the process of hardening Windows 10 operating system in simple, efficient, and scalable way. \n\nThe theoretical background of this study consists of known vulnerabilities, attack models, the security of Windows 10, hardening with group policy, and inspection of vulnerability scanners. With the support of this theoretical background the study was implemented as a case study where Windows 10 operating system was hardened with a preconfigured group policy. The vulnerabilities related to operating system were discovered by using five different vulnerability scanners. The scans were run before and after the hardening of the operating system. The success of hardening was evaluated through the vulnerability reports that were provided by the scanners. \n\nThe results show that hardening with preconfigured group policy did lessen the number of detected vulnerabilities. The was a big variety in the number of detected vulnerabilities between scanners as well as in the type of detected vulnerabilities and in the classification of these vulnerabilities. In addition to the result that the hardening enhances the security of Windows 10, this study also provides insights about the level of security of the operating system in general and what kind of results different vulnerability scanners provide related to the operating system. The study verifies that preconfigured group policies are beneficial in the process of hardening the operating system and high-lights the fact that multiple scanners should be used to detect vulnerabilities more comprehensively.\nThese results can be leveraged in organizations to help to plan what tools and procedures to use when detecting and preventing vulnerabilities.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2023-11-30T11:32:47Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-11-30T11:32:47Z (GMT).
