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 →

For years traffic monitoring tools assumed traffic was in clear text. This because when the Internet was created all the main protocols such as DNS, HTTP, SMTP, Telnet, POP were in clear. With this practice it was easy to report … Continue reading →

RFC8520 (Manufacturer Usage Description) specifies what is the intended (from the manufacturer standpoint) network behaviour of a network device. Being it defined in JSON format by the device manufacturer, it can be used for simple single-task devices such as a … Continue reading →

Icinga2 is an open source monitoring system which checks the availability of hosts and services, notifies users of outages and generates performance data for reporting. Thanks to its scalability and extensibility, it has become very popular (as Nagios successor) and … Continue reading →

nProbe (and ntopng) is a traditional packet-based application, whose lifecycle is Capture a packet and dissect/decode it Update the representation in memory of the network traffic (e.g. the flow table) Export the information Using packets for traffic analysis has several … Continue reading →

A few months ago, with ntopng 3.8, we introduced support for continuous traffic recording, that allows you to drill down historical data from the timeseries level up to raw packets. This is useful when troubleshooting a network issue or analysing a … Continue reading →

In the early Internet days, each network protocol was designed for a specific purpose: SMTP for sending emails, HTTP for the web and so on. In order to make sure that implementations where compliant with the specification, there was an … Continue reading →

For a while we have investigated how to combine system and network monitoring in a simple and effective way. In 2014 we have done a few experiments with Sysdig, and recently thanks to eBPF we have revamped our work to … Continue reading →
