Title: A stochastic model of cyber attacks with imperfect detection
Authors: Rui Fang - Shantou University (China) [presenting]
Abstract: A cyber security model with imperfect detection is introduced, in which one attacker launches multiple attacks against the target with adjusted strength based on the previous attacking outcome. Several sufficient conditions leading to the usual stochastic order on the first time to observe a truly compromised target, to observe a successful attack and to compromise the target are developed, respectively. The probability for the target to be truly compromised before observing some number of successful attacks is proved to increase (decrease) in the attacking (defense) strength. Monte Carlo simulations are also conducted to empirically illustrate the theoretical results.
