Modelagem e Verificação de Regras de Segurança em um Ambiente OpenFlow com Rede de Petri Colorida

The discussion of alternatives to the Internet architecture has been the subject of research for several years, resulting in a number of solutions and mechanisms that can help even the current approach. Within this context, the paradigm of Software Defined Networking (SDN) is becoming popular due to recent initiatives based on OpenFlow. This article presents an analysis of security policy rules applied in an environment based on OpenFlow. The analysis of the security policy rules is realized based on data obtained from a simulation of a scenario, modeled using Colored Petri Nets (CPN), and validated by the state space generated from the outputs of this model. The collected results are for a specific scenario. However, the approach is useful to analyze several types of systems. Thus, this research demonstrates that is feasible to employ CPN to model and validate security rules in an OpenFlow-based SDN.
