Secure cyber incident analytics framework using Monte Carlo simulations for financial cybersecurity insurance in cloud computing

摘要

The remarkable increasing demands of mitigating losses from cyber incidents for financial firms have beenrndriving the rapid development of the Cybersecurity Insurance (CI). The implementations of CI have coveredrna variety of aspects in cyber incidents, from hacking to frauds. However, CI is still at its exploring stage sornthat there are a number of dimensions that are uncovered by the current applications. The cyber attack onrncritical infrastructure is one of the serious issues that prevents the expansions of CI. This paper addresses CIrnimplementations focusing on cloud-based service offerings and proposes a secure cyber incident analyticsrnframework using big data, named as Cost-Aware Hierarchical Cyber Incident Analytics (CA-HCIA). Thernapproach is designed for matching different cyber risk scenarios, which uses repository data. We use MonternCarlo simulations for extracting the incident features based on the training datasets. The main algorithmsrnin CA-HCIA include Monte Carlo Cyber Feature Extraction (MC2FE) and Optimal Cost Balance (OCA)rnAlgorithms. Our experimental evaluation has provided the theoretical proof of the adoptability and feasibility.rnResults show that our proposal improves the cost of existing techniques in 7.98% and 15.39%.
