Los ataques de denegación de servicio (DOS) en la seguridad de redes definidas por software (SDN).

Software-defined networks (SDN), unlike traditional networks, centralize traffic management through a single controller, which has enabled an evolution in network architecture. Despite the advantages of this centralization architecture, it is vulnerable to various cyber attacks, especially Denial of Service (DoS) attacks, these threats aim to saturate the network and affect the availability of the service, compromising the security of the information being transmitted. This research analyzes in detail the vulnerabilities that by nature have SDN networks in its three fundamental layers (application, control and data), identifies the main types of DoS attacks according to their vulnerabilities and their impacts on the technological infrastructure in each of the layers of the network. Additionally, several strategies for detecting and mitigating the DoS attacks found in the study are proposed, using monitoring tools, strong authentication, load balancing and data encryption. The results obtained show that the implementation of appropriate security measures, such as intrusion detection systems (IDS) and distributed controllers, considerably reduce the impact of attacks on SDN networks. In conclusion, it is indicated that a combination of multi-layered security approaches and good configuration practices ensures the resilience and stability of SDN networks.
