论文摘要
网络安全动力学是一种数学方法,用于建模和分析网络中的网络攻击防御互动。在本文中,我们推进了一种最新的特征,以表征一种网络安全动力学,即预防和反应性网络防御动力学,该动力学是高度非线性系统模型的家族。我们证明,当时间依赖性参数是ergodic时,其具有时间相关参数的通用形式的这种动力学在全球上具有吸引力,并且当时间依赖性参数具有更强的(几乎)周期性的属性时(几乎)周期性。我们的结果取代了最先进的结果,包括相同类型的动力学,但与时间无关的参数是全球收敛的。
Cybersecurity dynamics is a mathematical approach to modeling and analyzing cyber attack-defense interactions in networks. In this paper, we advance the state-of-the-art in characterizing one kind of cybersecurity dynamics, known as preventive and reactive cyber defense dynamics, which is a family of highly nonlinear system models. We prove that this dynamics in its general form with time-dependent parameters is globally attractive when the time-dependent parameters are ergodic, and is (almost) periodic when the time-dependent parameters have the stronger properties of being (almost) periodic. Our results supersede the state-of-the-art ones, including that the same type of dynamics but with time-independent parameters is globally convergent.
