Evaluation of Cyber Security and Modelling of Risk Propagation with Petri Nets
AbstractThis article presents a new method of risk propagation among associated elements. On the
basis of coloured Petri nets, a new class called propagation nets is defined. This class provides
a formal model of a risk propagation. The proposed method allows for model relations between
nodes forming the network structure. Additionally, it takes into account the bidirectional relations
between components as well as relations between isomorphic, symmetrical components in various
be adapted to the propagation model of any systems’ characteristics; however, it is intentionally
proposed to assess the risk of critical infrastructures. In this paper, as a proof of concept example, we
show the formal model of risk propagation proposed within the project Cyberspace Security Threats
Evaluation System of the Republic of Poland. In the article, the idea of the method is presented as
well as its use case for evaluation of risk for cyber threats. With the adaptation of Petri nets, it is
possible to evaluate the risk for the particular node and assess the impact of this risk for all related
nodes including hierarchic relations of components as well as isomorphism of elements. View Full-Text
