Segurança e Automação em Redes SDN: Desenvolvendo uma Ferramenta de Automação de Testes de Segurança em Redes SDN

Abstract

The advance of software-defined networks (SDN) has introduced new challenges and op portunities for network security. The importance of this topic is evident, especially when analyzing the widespread adoption of this architecture in networks such as 5G. This work presents the development of an automation tool for security testing in SDN networks, aiming to integrate security into CI/CD cycles. The tool is designed to mitigate human errors caused by the complexity of configuring these networks, allowing for security testing whenever new configurations are applied, thereby reducing vulnerabilities in production environments. In the experiments conducted, the tool was used to simulate attacks such as TCP, UDP, and ICMP packet flooding, as well as MAC address flooding attacks. The results show that, even in an emulated environment, denial-of-service attacks can cause significant downtime in SDN controllers, such as ONOS, affecting both connecti vity between devices and the performance of network services. The proposed tool provides efficient in automating security testing, serving as a practical solution for environments that require agility and precision in their maintenance operations.
