Previous studies have been dedicated to strategies for combating malware propagation in data networks. One method to combat these deleterious actions is to establish preventive policies for system operations using network macroscopic models based on epidemiological studies, which is an efficient alternative compared to other methods. Among several studies based on the susceptible-infected-removed (SIR) epidemiological model applied in the context of computer networks, the introduction of antidotal populations in models has provided adequate descriptions of the real behavior of networks under attack. Currently, the susceptible-infected-removed-antidotal (SIRA) model is considered realistic for representing robust and complex networks. In this study, an approach related to the connection of different networks is presented as malware combat strategy design, deriving the effect of a network reliability loss on its neighborhood. Two clustered SIRA networks connected with whole dynamics were analytically and numerically studied, which allowed us to obtain the fundamental parameters for describing the malware dissemination between connected networks. Disease-free and endemic conditions, and several possible qualitative behaviors associated with the parameter space were identified, permitting the calculation of the basal reproduction number. This calculation allowed the design of control strategies to be implemented during the planning of essential safety measures in data networks.

群集计算机网络中的恶意软件传播

先前的研究致力于解决数据网络中恶意软件传播的策略。对抗这些有害行为的一种方法是使用基于流行病学研究的网络宏观模型为系统运行建立预防策略,与其他方法相比,这是一种有效的替代方法。在基于在计算机网络环境中应用的易感性感染去除(SIR)流行病学模型的几项研究中,模型中解毒菌种群的引入充分描述了受攻击网络的真实行为。当前,易感性感染去除窦道(SIRA)模型被认为是现实的,可以代表强大而复杂的网络。在这项研究中,一种与不同网络的连接有关的方法被提出作为恶意软件对抗策略设计,从而推导了网络可靠性损失对其邻域的影响。对两个具有整体动力学联系的集群式SIRA网络进行了分析和数值研究,这使我们能够获得描述连接网络之间恶意软件传播的基本参数。确定了无病和地方病状况,以及与参数空间相关的几种可能的定性行为,从而可以计算基础繁殖数。通过这种计算,可以在计划数据网络中的基本安全措施期间实施控制策略的设计。对两个具有整体动力学联系的集群式SIRA网络进行了分析和数值研究,这使我们能够获得描述连接网络之间恶意软件传播的基本参数。确定了无病和地方病状况,以及与参数空间相关的几种可能的定性行为,从而可以计算基础繁殖数。通过这种计算,可以在计划数据网络中的基本安全措施期间实施控制策略的设计。对两个具有整体动力学联系的集群式SIRA网络进行了分析和数值研究,这使我们能够获得描述连接网络之间恶意软件传播的基本参数。确定了无病和地方病状况,以及与参数空间相关的几种可能的定性行为,从而可以计算基础繁殖数。通过这种计算,可以在计划数据网络中的基本安全措施期间实施控制策略的设计。并确定了与参数空间相关的几种可能的定性行为,从而可以计算基础繁殖数。通过这种计算,可以在计划数据网络中的基本安全措施期间实施控制策略的设计。并确定了与参数空间相关的几种可能的定性行为,从而可以计算基础繁殖数。通过这种计算,可以在计划数据网络中的基本安全措施期间实施控制策略的设计。
