Analysis and control stratagems of flash disk virus dynamic propagation model

Abstract

Computer virus mainly contain two kinds: network viruses and flash disk (FD) viruses, we name viruses as FD‐virus which spread by the latter way. Many researchers have studied the network virus in light with epidemiology such as susceptible‐infected‐susceptible, susceptible‐infected‐recovered, susceptible‐exposed‐infective‐recovered (SEIR) and susceptible‐infectious‐detected‐removed, but there are few studies on FD virus propagation. In this paper, a new dynamic propagation model of FD‐virus, namely FD‐SEIR, is discussed. Unlike other existing computer virus propagation models, FD‐SEIR mainly considers the FD‐virus propagation between host and FD, which is embodied by introducing the FD state and new propagation rate. Furthermore, several related dynamics properties are investigated, along with the analysis of how to control the FD‐virus prevalence based on the equilibrium stability. The simulation results show that the proposed model can serve as a basis for understanding and simulating FD‐virus epidemics. Copyright © 2011 John Wiley & Sons, Ltd.

Influence of Removable Devices' Heterouse on the Propagation of Malware

“…Recently, the researches concerning malware have focused on those pieces malware spreading via removable devices [9][10][11][12][13]. Different from these researches, we present a model with a detailed depiction of the heterogeneity in removable devices' using rate.…”

“…To capture the influences of removable devices on malware, some mathematical models have been proposed [9][10][11][12][13]. In [9], Song et al presented the model by coupling a susceptible-infected-recovered (SIR) model with a susceptible-infected-susceptible (SIS) model [14].…”

“…In the model, a removable device would be infected with a certain rate if it was used on an infectious computer and then the infected removable device can infect other computers whenever it was used on them. To depict the computers which have been infected but are not yet infectious, Jin and Wang [10] put forward the susceptible-exposed-infected-recovered (SEIR) model by introducing the "exposed" state into the SIR model. L. X. Yang and X. Yang [11] further considered the model where the "exposed" state had limited infection ability.…”

Epidemic Model of Algorithm-Enhanced Dedicated Virus through Networks

“…Recently, a diversity of interesting results on this epidemic spread model [14][15][16][17][18][19][20][21] has been demonstrated; however, plentiful fascinating works, including barely developed viruses endowed with abilities, need to be exploited. Thanks to the great advance of algorithm and computing capability, artificial intelligence develops rapidly.…”

Modeling and Analyzing the Spread of Flash Disk Worms via Multiple Subnets

“…Jin and Wang describe the FD-SEIR model to analyze and control the Flash Disk worms [10]. Besides, Song et al present the worms model about the cross infection of computers and removable devices [11].…”
