Multi-Trigger Crypto CAT Bonds with On-Chain Settlement: Valuation and Optimal Design
Yue Wang, Yijia Li, Maochao Xu +1
Cryptocurrencies have experienced repeated large-scale losses from protocol exploits and exchange breaches, exposing insurers and investors to severe operational risks. This paper…
A Framework for Digital Asset Risks with Insurance Applications
Zhengming Li, Jianxi Su, Maochao Xu +1
The remarkable growth of digital assets, starting from the inception of Bitcoin in 2009 into a 1 trillion market in 2024, underscores the momentum behind disruptive technologies an…
Statistical Modeling of Data Breach Risks: Time to Identification and Notification
Maochao Xu, Quynh Nhu Nguyen
It is very challenging to predict the cost of a cyber incident owing to the complex nature of cyber risk. However, it is inevitable for insurance companies who offer cyber insuranc…
Modeling Multivariate Cyber Risks: Deep Learning Dating Extreme Value Theory
Mingyue Zhang Wu, Jinzhu Luo, Xing Fang +2
Modeling cyber risks has been an important but challenging task in the domain of cyber security. It is mainly because of the high dimensionality and heavy tails of risk patterns. T…
Should the Ransomware be Paid?
Rui Fang, Maochao Xu, Peng Zhao
Ransomware has emerged as one of the most concerned cyber risks in recent years, which has caused millions of dollars monetary loss over the world. It typically demands a certain a…
Pricing cyber insurance for a large-scale network
Lei Hua, Maochao Xu
Facing the lack of cyber insurance loss data, we propose an innovative approach for pricing cyber insurance for a large-scale network based on synthetic data. The synthetic data is…
Joint Cyber Risk Assessment of Network Systems with Heterogeneous Components
Gaofeng Da, Maochao Xu, Jingshi Zhang +1
Cyber risks are the most common risks encountered by a modern network system. However, it is significantly difficult to assess the joint cyber risk owing to the network topology, r…
Cyber Epidemic Models with Dependences
Maochao Xu, Gaofeng Da, Shouhuai Xu
Studying models of cyber epidemics over arbitrary complex networks can deepen our understanding of cyber security from a whole-system perspective. In this paper, we initiate the in…
A New Approach to Modeling and Analyzing Security of Networked Systems
Gaofeng Da, Maochao Xu, Shouhuai Xu
Modeling and analyzing security of networked systems is an important problem in the emerging Science of Security and has been under active investigation. In this paper, we propose…
An Extended Stochastic Model for Quantitative Security Analysis of Networked Systems
Maochao Xu, Shouhuai Xu
Quantitative security analysis of networked computer systems is one of the decades-long open problems in computer security. Recently, a promising approach was proposed in \cite{XuT…
A Characterization of Cybersecurity Posture from Network Telescope Data
Zhenxin Zhan, Maochao Xu, Shouhuai Xu
Data-driven understanding of cybersecurity posture is an important problem that has not been adequately explored. In this paper, we analyze some real data collected by CAIDA's netw…
Characterizing Honeypot-Captured Cyber Attacks: Statistical Framework and Case Study
Zhenxin Zhan, Maochao Xu, Shouhuai Xu
Rigorously characterizing the statistical properties of cyber attacks is an important problem. In this paper, we propose the {\em first} statistical framework for rigorously analyz…
Predicting Cyber Attack Rates with Extreme Values
Zhenxin Zhan, Maochao Xu, Shouhuai Xu
It is important to understand to what extent, and in what perspectives, cyber attacks can be predicted. Despite its evident importance, this problem was not investigated until very…
Some inequalities of linear combinations of independent random variables: II
Xiaoqing Pan, Maochao Xu, Taizhong Hu
Linear combinations of independent random variables have been extensively studied in the literature. However, most of the work is based on some specific distribution assumptions. I…
