In the past months we have extended our behaviour analysis introducing new features such as the ACL or device policies. For this reason we have rearranged the menus and create a new Policy menu (you can read more here) that contains all the configurations used by ntopng to trigger alerts. Sue to this, some pages […]

Exporting (Custom) Flows with Avro in nProbe Cento
This summer we introduced nProbe Cento 2.0. Before this release, Cento was supporting JSON serialization only when exporting flows to Kafka. JSON is straightforward and widely used, but it can be verbose and less efficient for high-throughput or resource-sensitive environments. To address these challenges, when exporting flows to ntopng, some time ago we introduced a […]
HowTo Monitor Router Interfaces Congestion Using SNMP
Sometimes it happens that your router is congested, and you ask yourself “How is it possible?” or “Who is responsible for congesting the network?” or “Which router/port is congested?”. You could simply answer the last question by using the SNMP/Flow Exporters Usage: HowTo Monitor SNMP Interfaces Utilisation and Congestion Rate; but what about the other […]
How nDPI Introduced Behaviour Analysis in Suricata
Last week we have attended Suricon 2024, the annual conference about Suricata and presented our work on how nDPI has been integrated with Suricata. At ntop we like to contribute to other open source projects we use and like, such as Suricata and Wireshark. One of the main limitations of Suricata is its inability to […]
A Deep Dive Into Traffic Fingerprints
Last week during SharkFest Europe 2024 we have presented what are network fingerprints and how they work. During the talk we (Luca and Ivan) have described how we have extended nDPI with support of network fingerprints, and how this work has been also integrated in Wireshark. We believe that fingerprints are an interesting technology that […]
Introducing ntopng Hosts Activity Monitor
Many users requested us a simple way to visualise hosts activity overtime. In essence have the ability to answer questions like: What hosts were active during the week-end When a host is using most of the network. What hosts were active when a certain event happened. This is what hosts activity monitor does. In the […]
