Network Background Traffic Simulation Based on Log

A simulation network environment is required for the development and evaluation of IDS (Intrusion Detection System), and network traffic simulation is the key technique in testing IDS. To work out the definition of attack type and background traffic in testing IDS, new network background traffic simulation software based on log is designed and developed referred to related technique and software in detail. Real network environment is simulated by this software to test IDS. The experimental results imply this simulation software is able to playback network traffic simulation data dynamically with various rates based on log and modify log data. This method improves the flexibility of testing IDS.
