Proposta e implementação de mecanismos de segurança aplicados ao contexto do CAARF-SDN

Abstract

The application of experimental networks through the combination of different paradigms, such as Context Sensitive Networks and Software-Defined Networks (SDNs), has proved to be a promising approach to the field of research and innovation in computers networks due to the combination of their main benefits such as scalability, dynamism, flexibility, easy management, role control, programming and network adaptation to meet user context changes and preferences. However, despite the various advantages arising from these new paradigms of networks, the literature study reveals some existing security challenges, since in addition to introducing new vulnerabilities to the context of computational networks, that paradigms end up potentiating existing vulnerabilities, in a much more critical way, increasing the risks of exploiting vulnerabilities by malicious users and cybercriminals. This work aims to analyze and catalog vulnerability and threats that exist in the context of the CAARF-SDN hybrid, with the objective of measuring the risks related to the aspects of Information Security (Confidentiality, Integrity, Availability, Non-Repudiation and Authenticity). In a second moment, solutions are proposed through the planning, implementation and validation of security mechanisms to address vulnerabilities and mitigate threats identified in the context of the CAARF-SDN framework, increasing network security, as well as its resources and services
