Most people use nDPI indirectly being it part of ntopng and many other non-ntop developed tools. However not many people know that nDPI can also be used from the command line to analyse network traffic. This is useful to create … Continue reading →

ntop tools are known for monitoring network traffic. However this traffic has to flow on physical networks and thus it is important to understand the physical network layout. LLDP (Link Layer Discovery Protocol) is a network protocol used to dynamically … Continue reading →

In short: encryption does not always mean that all the information exchanged is really encrypted. Another myth is that many people believe that the equation “encryption = security” holds. Unfortunately this is not true. This slide deck we presented at Sharkfest … Continue reading →

If you wonder how you can use Wireshark with containers, you now have a solution. This week we have presented at Sharkfest EU 2019 how we have integrated libebpfflow, our home-grown eBPF-based library for system introspection, with Wireshark. Thanks to … Continue reading →

This week we have presented at Suricon 2019 our work about unifying ntopng with Suricata. In short: Suricata is a great tool for analysing individual flows but It lacks a GUI It is blind to security threats when they use … Continue reading →

Summary With today’s traffic, most network IDSs (NIDS) have severe limitations in terms of visibility and ability to be easily circumvented by malware (for instance running a known service on a non-default port or the other way round), and thus … Continue reading →

Network traffic moving across a link often contains various types of traffic, for example in large companies it can include a mix of traffic coming from: Employees network Core company servers Guests network Other Analysing the traffic as a whole … Continue reading →

ntop believes that the future of traffic monitoring and network security will be played by the ability to inspect the behaviour of encrypted communications. It is fortunate that Sam Bocetta, a technical writer focused on network security and open source … Continue reading →

After nDPI v3 release, today we have rolled out an incremental update of nProbe Cento. In addition to fixing a few issues, we introduce in Cento some of the fingerprints implemented by nDPI so that we can move forward in … Continue reading →

Those who though that DPI died with the advent of traffic encryption should play with nDPI v3 that we’re introducing today. As already discussed, the pervasive use of encrypted traffic requires a new mindset when analysing network traffic. We decided … Continue reading →
