The internet in general is typically diverse, from the perspective of malware attacks, due to distinct configurations, firewall rules, antimalware signature sets, intrusion detection, and router policies etc. However many networks still have limited internal diversity, making them vulnerable to malware spreading. Diversity can provide a malware-halting technique and this paper models the spreading of infectious malware over networked computing devices using a model comprising a simple graph with N nodes of L types. A good measure of a model's diversity is the number of node types L. Nodes of the same type share an exploitable vulnerability, whereas nodes of different types have no common exploitable vulnerability. An epidemiological model represents the spreading phase of multi-malware outbreaks. The analysis of this phase establishes a lower bound on the diversity L needed by various halting techniques proposed for spreading networks with three different topologies: i)Sparse and homogeneous, ii) Sparse and inhomogeneous, iii) Dense and homogeneous.

This paper is behind a paywall. The abstract claims a novel approach to SCADA IDS based on multi-attributes but does not say what those attributes are. It also claims a ‘comprehensive solution to mitigate varied cyberattack threats’. Information is limited in the abstract but there is little indication that major progress can be found in the full paper.
