How Historical Traffic Behaviour Analysis Works

Posted · Add Comment

In ntopng we have implemented various techniques for analysing historical traffic. This post shows you the options available: In timeseries you can see the current traffic rate (line) or the traffic rate of the previous period of time (dotted). This allows you to visually analyse when traffic deviates from previous period of time (see for […]

DoS Detection Using ntopng and NetFlow/IPFIX

Recently ntopng has been used in academia for detecting DoS (Denial of Service) attacks using NetFlow flows. In this thesis (note that the document it is written in Italian) it is shown how ntopng has been successfully used collect flow and use them to detect DoS attacks. Enjoy !

Despite ntop has implemented rich network metrics over the years, the two most important metrics that people keep asking us are volume (how much) and time (how long).  Timeseries offer a quick view of the traffic and allow people to immediately spot traffic peaks or absence of transmissions. They are good for traffic analysis but […]

As previously announced, we have added a new entry in the nBox product list: the nBox Mini. This is a small rugged device with 1 and 2.5 Gbit Ethernet port designed to be used as turn key solutions for monitoring small-mid size networks (typically up to 255 hosts), it is preconfigured to accept mirrored traffic […]

HowTo Analyse NetFlow/IPFIX/sFlow pcap Traces

Posted · Add Comment

Dumping sFlow/NetFlow/IPFIX flows in pcap format can be very useful for troubleshooting or for creating a compact traffic dump. For instance you can dump flow traffic with n2disk (wireshark, or tcpdump) and store them in pcap format, and eventually share them with a shared disk or sent via email. Flows are usually analysed live with […]
