Iftop is a free software command-line system monitor tool developed by Paul Warren. It produces a real-time stream of incoming and outgoing network communications from the operating system iftop is running within. [2] By default, the connections are ordered by bandwidth usage, with only the largest ("top") bandwidth consumers shown.
A network tap is an even more reliable solution than to use a monitoring port since taps are less likely to drop packets during high traffic load. On wireless LANs , traffic can be captured on one channel at a time, or by using multiple adapters, on several channels simultaneously.
Zeek is a free and open-source software network analysis framework. Vern Paxson began development work on Zeek in 1995 at Lawrence Berkeley National Lab. [3] Zeek is a network security monitor (NSM) but can also be used as a network intrusion detection system (NIDS). [4] The Zeek project releases the software under the BSD license.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
Snort is a free open source network intrusion detection system (IDS) and intrusion prevention system (IPS) [4] created in 1998 by Martin Roesch, founder and former CTO of Sourcefire. [ 5 ] [ 6 ] Snort is now developed by Cisco , which purchased Sourcefire in 2013.
Data monitoring switches support either or both of the following internal management interfaces: A text-based command-line interface (CLI) accessed with a terminal emulation program either locally over a serial port or remotely over a secure (e.g., SSH) network connection; this interface is sometimes preferred by network administrators, although many data center professionals complain that CLI ...
Able to leverage more than one server to distribute the load of network monitoring. Inventory Keeps a record of hardware and/or software inventory for the hosts and devices it monitors. Platform The platform (Coding Language) on which the tool was developed/written. Data Storage Method Main method used to store the network data it monitors. License
Network detection and response (NDR) refers to a category of network security products that detect abnormal system behaviors by continuously analyzing network traffic. NDR solutions apply behavioral analytics to inspect raw network packets and metadata for both internal (east-west) and external (north-south) network communications.
