Argus is the first data network flow system, invented by Carter Bullard at Georgia Tech in the early 1980s and adapted for cybersecurity incident response at Carnegie Mellon's Software Engineering Institute's first Computer Emergency Response Team (CERT) in the late 1980s. Since then, network flow technology has evolved into a crucial component of modern networking and cybersecurity, with Argus playing a significant role in this progress.

Argus is a network auditing solution that provides an engine for auditing all network traffic, not just IP.

It was inspired by the Public Switched Telephone Networks (PSTN) Call Detail Record (CDR) and is designed to track all network activities in a way that supports all types of network management functions, including security monitoring. Auditing is a critical component of NIST's security controls.

The Argus Project is an open-source initiative focusing on demonstrating proofs of concept for all aspects of large-scale network awareness obtained from network traffic data.

Argus aspires to be at the "bleeding edge" of network flow technology, rapidly analyzing packets on the wire or in captures to produce the most comprehensive network flow data possible.

The Argus system aims to handle a broad range of network flow data processing concerns, including scale, performance, application, privacy, and value.

Although Argus is a proof of concept project, it has been operationally deployed in the US Government, the US Department of Defense, the Department of Homeland Security, the Department of Energy, large enterprises, and university networks worldwide.

It is widely used in network research, enabling a variety of projects ranging from network performance analysis to situational awareness, cyber security, machine learning, and even chip design for Software Defined Networks (SDNs).

The Argus architecture is intended to facilitate network auditing on a modest to very large scale.

Real-time data contains a wealth of information that can be kept in files for later processing or cobbled together to offer real-time network data streams for simple network awareness, large-scale distributed visibility, and even active cyber protection.

Argus is a free and open-source project licensed under the GNU General Public License version 2. In order to ensure that everyone may use Argus, if the GPL is not to your satisfaction, please contact Argus for information on other licensing alternatives.

Argus is a network auditing system that monitors network traffic. It is made up of two packages in total. A packet processing network flow sensor, argus, that generates Argus flow data, and a collection of argus data processing programs, called argus-clients, that can be coupled to build high-performance data flow pipelines for processing network data in real-time, or uncoupled to support large data science analytics, such as statistical analysis and machine learning, are the core components of the argus system.

A simple report, such as billing or resource use reports, can be generated on an endpoint basis using the records that have been collected and processed. When reporting on network function degradation or verifying SLAs, Argus performance measurements can be used to provide information. Because of the ability to annotate network flow data with geolocation information, reports can be organized by nation, state, and AS number.

AirCrack-ng is compatible with a wide variety of wireless cards that use the Atheros, Hermes, or Prism chipsets. After installing the drivers, begin collecting packets using the supplied capture tool airodump-ng, which captures and assembles the required packets. Once a significant number of packets has been collected, the AirCrack-ng application can be used to decrypt the data.

7. Wireshark

Few programs are as useful to IT professionals as Wireshark, the de facto standard for network packet capture. Wireshark enables you to capture and visualize network packets at a fine level. After decompressing these packets, you can use them for real-time or offline analysis. This program enables you to magnify your network traffic and then filter and drill down into it, assisting with network analysis and, ultimately, network security.

Wireshark is a network protocol analyzer or an application that captures packets passing over a network connection, such as one connecting your computer to your home office or the internet. In a typical Ethernet network, the term "packet" refers to a distinct unit of data.

Wireshark is the world's most popular packet sniffer. Wireshark, like any other packet sniffer, performs three functions:

  1. Wireshark listens in real-time to a network connection and then captures whole streams of traffic - potentially tens of thousands of packets at a time.
  2. Through the use of filters, Wireshark is capable of slicing and dicing all of this random live data. By employing a filter, you can retrieve only the data that you require.
  3. Wireshark, like any other decent packet sniffer, enables you to dive right into the heart of a network packet. Additionally, it enables the visualization of full conversations and network streams.

Wireshark is useful for a variety of tasks, including diagnosing network performance issues. Wireshark is frequently used by cybersecurity professionals to trace connections, analyze the contents of suspicious network transactions, and spot surges in network traffic. It's a critical component of any IT professional's toolset - and preferably, the IT professional possesses the necessary skills to utilize it.

8. Tcpdump

Tcpdump is a command-line utility for capturing and analyzing network traffic passing through your system. It is frequently used to assist in troubleshooting network issues and as a security tool.

Tcpdump is a robust and adaptable tool that comes with a plethora of options and filters. It may be used in a variety of situations. Because it is a command-line tool, it is excellent for use on distant servers or devices without a graphical user interface in order to collect data for subsequent analysis. Additionally, it can be run in the background or as a scheduled job via technologies such as cron.

It is included with the majority of Linux/Unix-based operating systems. Additionally, tcpdump allows us to save the recorded packets to a file for later study. It stores the file in the pcap format, which may be inspected using the tcpdump command or an open-source graphical user interface (GUI) program called Wireshark (Network Protocol Analyzer), which can read tcpdump pcap format files.

This software is based on the libpcap interface, a system-independent portable interface for capturing network datagrams at the user level. Contrary to its name, tcpdump may also capture non-TCP communications, such as UDP and ICMP. One of the key advantages of this technology is its widespread availability, which has made it the de facto standard format for collected network traffic. The tcpdump tool is included with a large number of BSD, Linux, and Mac OS X distributions, and a Windows version is available. Due to its extensive history, there are also a plethora of references available on the Internet and in text form for those interested in learning the tool.
