Resumo


A programabilidade resultante da abordagem Software Defined Networking (SDN) facilita a integração das funcionalidades de firewalls, sistemas de prevenção de intrusão (IPS) e switches, permitindo a rápida reconfiguração da rede em caso de detecção de anomalias. Neste artigo, a arquitetura proposta visa estruturar uma medida de segurança distribuída que integra firewall, IPS, switches e uma entidade controladora para suportar instâncias de Internet das Coisas (IoT), permitindo a identificação de comportamento anômalo de dispositivos IoT pelo IPS, levando então a SDN a bloquear os ataques o mais próximo possível das fontes, reduzindo o volume de tráfego malicioso e isolando o dispositivo infectado do resto da rede..
