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.

The following article presents the results on the impact of encryption algorithms and the cryptographic hash function on the QoS (Quality of Service) transmission in a computer network. A network model supporting data encryption using the AES algorithm and the MD5 and SHA hash functions used in VPN tunnels was designed and tested. The influence of different data length on the quality of transmission in a secured network was studied. The measurements and tests of networks were performed according to two methodologies ITU-T Y.1564 and RFC 2544. The impact of the data encryption mechanism on bandwidth, data loss and maximum delays was examined. The secured network tests were performed with different combinations of encryption algorithms and hash functions of the VPN tunnel in the ESP (Encapsulating Security Payload) transport mode.
