Cyber Insurance for Heterogeneous Wireless Networks

Abstract

Heterogeneous wireless networks (HWNs), composed of densely deployed base stations of different types with various radio access technologies, have become a prevailing trend to accommodate ever increasing traffic demand. Nowadays, users rely heavily on HWNs for ubiquitous network access to support critical applications such as financial transactions, e-health, and public safety. Cyber risks, representing one of the most significant threats to network security and reliability, are increasing in severity. To address this problem, this article introduces the concept of cyber insurance to transfer the cyber risks in HWNs to a third-party insurer. First, a review of the enabling technologies for HWNs and their vulnerabilities to cyber risks is presented. Then the fundamentals of cyber insurance are introduced, and subsequently, a cyber insurance framework for HWNs is presented. Finally, open issues are discussed and the challenges are highlighted for integrating cyber insurance as a service of next generation HWNs.
