How do you select the right network forensic tool?

Network forensics is the process of capturing, analyzing, and presenting network data for security investigations. It can help you identify the source, scope, and impact of cyberattacks, as well as collect evidence for legal purposes. But how do you select the right network forensic tool for your needs? Here are some factors to consider.

1 Your goals and requirements

Before you choose a network forensic tool, you need to define your goals and requirements. What kind of network data do you want to capture and analyze? How much storage and processing power do you need? How often do you need to perform network forensics? How do you want to present and report your findings?

The key is to be flexible. Network Forensics has three major outcomes. You may find a file where the code is benign, a known malicious file or an unknown malicious file. The latter will be more complex to investigate. However, in any case, you should be ready to pivot as your forensic investigation changes. Overall, It is likely that your time, tools and resources will need to change along the way.
