Not all ntop users know that ntopng natively implements multitenancy support. Namely you can use ntopng to collect and analyse traffic from multiple users, and show to each user its own traffic, hiding all the rest. All you need to do is very simple Start ntopng and configure it to receive monitored traffic. You can […]
Rethinking Flow Visualisation in ntopng
For years ntopng has listed flows in a tabular view. Our users are used to it, and over time we have added new features and filtering capabilities. What we have not yet done, is rethink how flows are reported. Reworking the ntopng GUI is something we will tackle in the next major ntopng release, but […]
Scaling Up: How To Collect, Analyse, and Store Flows at Scale (100 Gbit+)
Most ntop tools such as nProbe cento and n2disk have been designed to run at high speed (today we consider 100 Gbit a high-speed link). ntopng instead has to perform many activities including behavioral traffic analysis that makes it unable to process traffic well above 10 Gbit. In this case you can use nProbe Cento […]
Using Python (including Jupyter Notebook) with ntopng
Most programmers and network/security administrators are familiar with the Python language. As from time to time we receive requests from our users for creating custom reports, or extracting other type of data (e.g. alerts or timeseries) from ntopng, we have decided to create a Python API for ntopng. Such API allows developers to extract data […]
HowTo Use Periodic Traffic Analysis in Cybersecurity
Since v5 ntopng has the ability to detect periodic activities, i.e. activities that are repeated periodically at a given pace (note that each activity can have a different frequency, and ntopng is able to detect them). Periodic activities are not bad per se (e.g. an email application fetches new messages every 5 minutes) but it […]
Short 1Q23 Roadmap
Happy new year ! At ntop we’re working hard even during these to finish new software releases that we plan to release this quarter. In our December 2022 webinar we have previewed our ongoing developments that we plan to complete soon, and that include: First release of cockpit-based totally redesigned nBox GUI that everyone can […]
HowTo Monitor Zoom Performance and Video/Call Quality
Zoom is a popular platform for video communications and team collaboration. As many other cloud services, network administrators need to supervise Zoom network traffic usage. DPI toolkits such as nDPI are useful for identifying Zoom traffic for supervising the network bandwidth used by your Zoom calls. Recently we have took advantage of this research work […]
What’s New in ntopng: Network Assets
Hello everybody! Welcome back to the weekly blog post of this serie used to update you with the latest ntopng features and graphical changes. Please let us know your feedback! Today we are going to talk about the Asset Map. Have you ever asked yourself, what are the NTP servers in your network? Or, are […]
ntop Webinar on Dec 14th: Community Meeting and Future Plans
Many things have happened this year: new products, several improvements to existing tools, and a lot of new ideas that we want to discuss with our community. For this reason we have organised a webinar on December 14th at 16:00 CET / 10:00 EST for meeting our community, show what we’re doing and plan where […]
Introducing Lua-based Host and Flow Behavioural Checks
With ntopng version 5 we have migrated performance sensitive sections of the ntopng engine from Lua to C++. This has enabled ntopng to scale up nicely while reducing resource needs such as CPU and memory. The drawback is that writing behavioural checks in C++ is not something that everyone can do. For this reason we […]
