The Cyber Challenge Network traffic flow data has been carefully simulated in a realistic manner at NGAS R&T Space Park (www.northropgrumman.com) which mimics operations and anomalies that correspond to real-world events. The simulated data is over 217 hours (≈9 days) and captures the interactions between hosts in the network. The dataset contains the to-from information of the interactions along with the time stamps. The time-aggregated graph representing the whole network has 125 nodes and 352 undirected edges connecting them.
