Abstract
Sodinokibi Ransomware virus becomes a severe threat by targeting data encryption on a server, and this virus infection continues to spread to encrypt data on other computers. This study aims to mitigate by experiment with building a prevention system through computer network management. The mitigation process is carried out through static, dynamic, and Software-Defined Networking (SDN) analysis to prevent the impact of attacks through programmatic network management. SDN consists of two main components in its implementation, the Ryu controller and Open Virtual Switch (OVS). Result testing mitigation system on infected networks by crippling TCP internet protocol access can reduce virus spread by 17.13% and suppress Sodinokibi traffic logs by up to 73.97%. Based on the percentage data, SDN-based mitigation in this study is per the objectives to make it possible to mitigate Ransomware attacks on computer network traffic.
