GUEVARA, P et al. Basic definitions for discrete modeling of computer worms epidemics. Ing. Investig. [online]. 2015, vol.35, n.1, pp.79-85. ISSN 0120-5609.  https://doi.org/10.15446/ing.investig.v35n1.44323.

The information technologies have evolved in such a way that communication between computers or hosts has become common, so much that the worldwide organization (governments and corporations) depends on it; what could happen if these computers stop working for a long time is catastrophic. Unfortunately, networks are attacked by malware such as viruses and worms that could collapse the system. This has served as motivation for the formal study of computer worms and epidemics to develop strategies for prevention and protection; this is why in this paper, before analyzing epidemiological models, a set of formal definitions based on set theory and functions is proposed for describing 21 concepts used in the study of worms. These definitions provide a basis for future qualitative research on the behavior of computer worms, and quantitative for the study of their epidemiological models.
