Risk assessment and mitigation of information security threats in 5G networksSmirnov, Ivan (Avtor) Koucheryavy, Yevgeni (Avtor) IMT-20205Gwireless technologiestechnical specificationinformation securityCASEThe 5G communication networks have been destined to become one of the pillars of the digital economy, driven by artificial intelligence (AI), machine learning (ML), Big Data, Internet of Things (IoT) and robotization. The 5G networks have inherited many vulnerabilities from the preceding systems. In this regard, the issue of a proper information security (IS) is one of the highest priorities. Our aim is to assess the risks of realizing some IS threats in 5G wireless networks and propose security measures to mitigate them. In particular, we analyze vulnerabilities for the 5G networks related to the user device (UE), wireless interface (Air Interface), core network (CN), application server, open-source applications, AI, physical layer threats, threats from a poorly secured 4G/LTE network, SDN security related to vulnerabilities in SSH using various attacks such as Terrapin attack, as well as regulatory requirements. We propose measures to reduce by some 16% the threat probabilities and their impacts benefitting from ISPs and telecoms to avoid problems related to the data availability, leakage and compromise.20252026-06-10 12:51:04Članek v reviji183299UDK: 004.056ISSN pri članku: 0013-5852COBISS_ID: 280416003sl
