8.2 Random Error Spreading on Interconnected Networks

Several epidemic models have been used to describe how an infection (such as a malware) can spread over a network [2, 14, 23, 28, 6, 29]. However, these models assume homogeneous spreading (just as the underlying epidemic models usually do), which is not suitable in most real-life situations. The reason why they are considered to be unsuitable is that the structure of networks is usually heterogeneous. A couple of approaches that take into account heterogeneity in the case of disease spreading are described in [12] and [15]. In this section, we briefly summarize a general model for random error spreading on an heterogeneous network that was introduced in [10]. Subsequently, we illustrate how it can be used in various situations (e.g., to describe consequences of a cyberattack) and discuss several issues that might arise when applying it.
