A Step-by-Step Guide to Analyzing Traffic with Wireshark

To do packet analysis with Wireshark, follow these steps:

  1. Download and install Wireshark on your computer.
  2. Open Wireshark and select the interface that you want to monitor from the “Interface” drop-down menu in the toolbar.
  3. Click on the “Start” button to begin capturing packets.
  4. As packets are captured, they will be displayed in the packet capture window. You can use the various filters and statistics in Wireshark to analyze the packets and gain insights into your network traffic.
  5. To begin analyzing a packet, simply select it from the packet capture window and examine the information that is displayed in the various panes of the Wireshark interface.
  6. For example, let’s say that you want to analyze a packet that was sent from the IP address to the IP address First, you would use the filter “ip.addr== && ip.addr==” to only display packets that were sent between these two IP addresses.
  7. Then, you would select one of the packets from the filtered list and examine the information in the “Packet Details” and “Packet Bytes” panes.
  8. In the “Packet Details” pane, you would see information about the protocol that was used to send the packet, the source and destination addresses, and other details.
  9. In the “Packet Bytes” pane, you would see the raw data of the packet in both hexadecimal and ASCII formats.
  10. By examining the information in these panes, you can gain insights into the packet and understand how it was sent and what information it contains.
  11. You can continue to use filters and examine packets in this way to gain further insights into your network traffic and identify potential security threats or network issues.
