What is Network Forensics?

Network forensics is about looking at how computers talk to each other. It helps us understand what happens in a company's computer systems. This is important when we need to find out if someone did something wrong using computers. To do network forensics well, we need to follow certain steps and use special tools. These tools help us see and understand the information that moves between computers.

We'll talk about the steps to do network forensics and the tools we can use. We'll also explain how network forensics is different from looking at just one computer, and why both are needed to solve computer crimes.

What is Network Forensics?

Network forensics looks at how computers talk to each other on networks. It checks the information that moves between computers. This helps find out if someone did something bad using computers. Network forensics looks at network traffic, logs, and other data about network use. It helps solve computer crimes, network problems, and data theft. The main job of network forensics is to find and keep digital proof that can be used in court. By looking at network records, people who solve computer crimes can piece together what happened.

They can see how people talk and when things happen. This helps them understand crimes or strange events better. When looking at the records, they check for signs of people talking, if files were changed, if certain words were used, and other clues that something bad might have happened.

Network Forensics Examination Steps

Identification

First, decide what you need to look at. This helps you know what information to collect and what tools to use. This step is very important for the whole process.

Preservation

Next, keep the evidence safe. Make copies of important data and store them securely. Collect data in a way that keeps it unchanged. Use tools like Autopsy or Encase to keep the evidence safe.

Collection

Now, gather the data. You can do this by hand or with special tools. It's often best to use both ways. By hand, you look at each file. With tools, you use software to check network traffic and get data.

Examination

Look closely at the collected data. Check for unusual things that might show a security p
