Network forensics in cyber security is the process of collecting and analyzing data that is related to a network. This data can be collected from computers, routers, switches and other devices connected to the network. The information that is collected can help with investigations as well as identify strategies for improving an organization's security efforts.
Administrators can use Network Forensic Analysis Tools (NFATs) to monitor their network for unusual activity, do forensic analysis, and acquire a comprehensive picture of their environment. It looks at three NFATs to get a better understanding of the tool: SilentRunner, NetIntercept, and NetDetector.
The goal of network forensic analysis is to monitor network traffic in order to detect and prevent attacks, as well as to collect evidence in order to determine the source of an attack.
Identification, preservation, collection, examination, analysis, and presentation, as well as incident response, are all steps in a network forensics investigation.
Modern network forensic techniques confront a number of obstacles that must be overcome in order to improve the methodologies. High storage speed, the need for plenty of storage space, data integrity, data privacy, access to IP addresses, and the location of data extraction are only a few of the major challenges.
