Using packet capture and storage, telecommunications carriers can provide the legally required secure and separate access to targeted network traffic and can use the same device for internal security purposes. Collecting data from a carrier system without a warrant is illegal due to laws about interception.
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.
As promiscuous mode can be used in a malicious way to capture private data in transit on a network, computer security professionals might be interested in detecting network devices that are in promiscuous mode. In promiscuous mode, some software might send responses to frames even though they were addressed to another machine.
A packet capture appliance is a standalone device that performs packet capture. [1] Packet capture appliances may be deployed anywhere on a network, however, most commonly are placed at the entrances to the network (i.e. the internet connections) and in front of critical equipment, such as servers containing sensitive information.

Most current Unix-like systems provide a mechanism by which a program can capture network traffic to and from the machine running the program and, in some cases, other traffic to which that machine is attached. However, these mechanisms are significantly different from one another; the libpcap library provides a common API to access these ...
Argus monitors all network traffic, data plane, control plane and management plane, not just Internet Protocol (IP) traffic. Argus captures much of the packet dynamics and semantics of each flow, with a great deal of data reduction, so you can store, process, inspect and analyze large amounts of network data efficiently.
A protocol analyzer is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel.Such a channel varies from a local computer bus to a satellite link, that provides a means of communication using a standard communication protocol (networked or point-to-point).
