More about Ntopng

Ntopng basically is a network traffic probe that will monitor network usage. It is based on libpcap, a Library written as part of a larger program called TCPDump. Ntopng is based on Redis key value server rather than traditional database, leverages nDPI for protocol discovery, supports host geolocation, and can display real-time flow analysis for connected hosts.


Main Features of Ntopng:

  • Packet capture → Packet capture / transmission using basic hardware with PF_RING. Zero-copy package distribution across threads, applications, and virtual machines. Includes Libpcap support for seamless integration with legacy applications.
  • Traffic recording → Lossless network traffic recording of 10 Gbit and above with n2disk. Industry standard PCAP file format. It allows to quickly retrieve packages using BPF. Accurate traffic reproduction with disk2n.
  • Network probe → nProbe- NetFlow v5 / v9 / IPFIX extensible probe with plug-in support for L7 content inspection.
  • Report on the use of the IP protocol → Even going so far as to classify it by type of protocol.
  • Traffic analysis → High speed web based traffic analysis and flow collection using ntopng. Persistent traffic statistics in RRD format. Layer 7 analysis leveraging nDPI, an open source DPI framework. Even going so far as to classify the traffic according to the source / destination.
  • Geolocate and Overlay Hosts → This will be done on a geographic map.
  • Alert engine → We can capture anomalous and suspicious hosts.
  • Produce network traffic statistics → Using HTML5 / AJAX technology.
  • We will have full support for current network protocols → Including IPv4 and IPv6.
