What are network forensic analysis tools? We need to Know

Network Forensics is a discipline that deals with conducting retrospective analysis to accumulate evidence from a cyberattack. It thoroughly inspects network traffic to facilitate the identification of adversaries, blind spots within the framework used to carry out an attack, etc.

A host of tools are at the disposal of the security operations team that allows for conducting network forensic analysis. These tools analyse North-South and East-West network traffic to its granular details for conducting network audits, comprehending network transactions, and using protocols and software for optimal Network Forensic investigation.

Once the tools analyse the traffic, they convert the raw data into a format comprehensible by humans. The data contains information about each network transaction like source IP, destination IP, packet count, MAC address, etc.

Network forensics tools aid in fortifying networks against both subtle and malevolent threats. They assist an enterprise in gaining a comprehensive understanding of its network environment and avoiding data breaches that could cost them money, a competitive advantage, or both. When dealing with a range of technical, operational, and organisational issues, having a detailed record of network activity can be extremely beneficial.

Artificial Intelligence (AI) and Machine Learning (ML)-enabled Vehere PacketWorker is the top-notch network forensic tool with an integrated content management system that makes analysis easier and eliminates the need for third-party software. While conducting the investigation or threat analysis the use of advanced analytics provides better investigative.

Evidence collection, indexing, and analysis are key to network forensic investigations. To access data and aid in analysis, investigators must rely on effective tools.

Network forensics is used by investigators and cybercrime professionals to track down all network transactions and create timelines based on network events logs.

There are two methods for performing network forensics investigation. The first is the “catch it as you can” technique, which involves recording and analysing all network data. To save earlier data for future forensics, this technology necessitates a lot of storage.

The “stop, look, and listen” strategy comprises analysing each data packet that travels across the network and only collecting what is deemed suspicious and worthy of further examination; this method can consume a lot of computing power but requires less storage space.

Analyzing the events leading up to an attack in great detail not only aids in the development of a powerful threat hunting and response mechanism enabling cyber situational awareness, but it also aids in the prevention of future assaults.
