Visualizations are a capability that can be leveraged to enrich cybersecurity defenders. Riverside is an open-source network security visualization tool that showcases live traffic between internal hosts and external remote hosts in a real-time network graph. While capturing netflow from internal network devices, users can traverse backwards in time to analyze previous network activity for enriched situational awareness and a thorough understanding of their network security posture. This utility supplements existing tooling to provide more insight for use cases such as incident response, analysis and investigation, and identification of true assets used within a network environment.
