| Internet epidemics have been long discovered and studied. However, few have noticed that non-Internet epidemics which take advantage of Social Networks are also destructive to information systems.
In this paper, we think of the non-Internet viruses which transfer through portable devices, especially flash drives. We take Rose epidemic as a case study and build a model with a system of differential equations and closed-form solutions, for three propagation scenes of Rose correspondingly. With both theoretical and numerical analysis, we find out that (1) Rose is able to infect hosts as exponentially as the Internet-based worms do;(2) In the Internet Bar scene, it is difficult to contain Rose even with reactive recovery measures; (3) the most influential factors for Rose’s propagation are the amount of hosts and portable devices and the lifetime of Internet Bar machines, while the arrival rate of clients and the proportion of immune machines only affect in the Print Service Office scene. |
