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 binary/TLV format for data serialization, implemented in our open-source nDPI library. However, despite this being an open format, it is not widely used. For this reason, in order to improve interoperability with other solutions, we …

Released Cento 2.0: Hardware Flow Table Offload, Avro Export and Much More
This is to announce that Cento 2.0 is out! This new major release introduces many new great features. First of all it adds support for offloading flows to Napatech SmartNICs featuring Flow Manager. This new feature has been presented at IEEE HPSR (IEEE International Conference on High Performance Switching and Routing) and demonstrated to provide a significant performance boost and dramatically reduce the PCIe and memory bandwidth utilisation when processing 100 Gbit (or more) links with full-speed traffic. This can be used both by standard cento to accelerate passive monitoring, …

Advancements in Traffic Processing Using Programmable Hardware Flow Offload
This week we have presented at the IEEE HPSR (IEEE International Conference on High Performance Switching and Routing) our latest work that shows how nProbe can benefit of acceleration provided by modern SmartNICs to achieving multi-100 Gbit traffic processing (both passive and inline) on low-end servers while deep-packet inspecting traffic using nDPI. If you want to know more about it, you can view the presentation slides, or read thw paper. Your feedback is welcome. Enjoy ! …

HowTo Build a 100 Gbit NetFlow Sensor Using nProbe Cento
When it comes to monitor a distributed network, to get a picture of the Network traffic flowing through the uplinks or on critical Network segments, NetFlow like technologies are usually the answer. nProbe Pro/Enterprise and nProbe Cento are software probes that can be used to build versatile sensors able to export flow information in many different formats, including NetFlow v5/v9/IPFIX, Kafka, Elasticsearch, ClickHouse, MySQL, CSV files, etc. All this at very high speed. nProbe Pro/Enterprise has been designed for low/mid rate (1/10 Gbps) while nProbe Cento has been designed to …

Enabling Zeek and Suricata On-Demand at 40/100 Gbit using PF_RING
Overview Those of you who have some experience with IDS or IPS systems, like Zeek and Suricata, are probably aware of how CPU intensive and memory consuming those applications are due to the nature of the activities they carry on (e.g. signatures matching). This leads to high system load and packet loss when the packet rate becomes high (10+ Gbi+) making these IDSs unlikely to be to deployed on high-speed networks. As nProbe Cento can analyse networks up to 100 Gbit while using nDPI for ETA (Encrypted Traffic Analysis), ntopng …

Introducing nProbe Cento 1.14
This is to announce a new release of the ntop’s 100 Gbit probe, nProbe Cento 1.14. In this version we have integrated the latest features from nDPI, the ntop’s Deep-Packet-Inspection engine, that is now 2.5x faster than the previous version. Flows are enriched with Flow Risks, which represents a set of issues detected by nDPI, and a Flow Score, which is computed based on the risks severity, to indicates how bad is each flow. The flow dump has also been improved by adding the Community ID (a flow identifier which …

Introducing nProbe Cento 1.12: Combining Visibility and Cybersecurity at 100 Gbit
This is to announce the released of cento 1.12 that is a maintenance release for ntop’s 100 Gbit probe. In this version we have integrated support of the latest nDPI features to combine processing speed with latest innovations in application detection an cybersecurity. Cento’s JSON output has been greatly enhanced and it includes all the nDPI-dissected information by streaming JSON-based data to Kafka or ElasticSearch/Syslog consumers. This to make cento useful to cybersecurity analysis by combining visibility and security at 100 Gbit by streaming. Enjoy! Changelog New Features Core engine …
