Open-source flow monitoring with SENSOR: Benefits and trade-offs - Help Net Security

Flow monitoring tools are useful for tracking traffic patterns, planning capacity, and spotting threats. But many off-the-shelf solutions come with steep licensing costs and hardware demands, especially if you want to process every packet. A research team at the University of Tübingen has built an alternative: an open-source, cost-effective, and distributed platform for collecting unsampled IPFIX data. Their system, called SENSOR, uses open-sour…
