With the emerging Internet of Things (IoT) technologies, malware spreading over increasingly connected networks becomes a new security concern. To capture the heterogeneous nature of the IoT networks, we propose a continuous-time Susceptible-Infected-Recovered (SIR) epidemic model with two types of malware for heterogeneous populations over a large network of devices. The malware control mechanism...
Many computer viruses cause repeated epidemics of malwares and induce a serious challenge for IT security. IT security needs to apply the countermeasures iteratively during series of epidemic events to stop the propagation process. We consider a modification of Susceptible-Infected-Recovered model with impulses of control and present the model of propagation of two forms of malware. We discuss the...
The security risks incurred by the spread of malware in computer and wireless networks can be reduced by the immunization of nodes, using security and antivirus patches. Malware, which captures personal and corporate confidential data, induces different damages, including costs generated by the necessity to compensate disclosure of private information, loss of money and social damage caused by loss...
