Use this concept to understand how PCAP files help capture, analyze, and identify network traffic and assets in operational technology environments using Cyber Vision Center.


A packet capture (PCAP) file is a file format that

  • records raw network traffic data captured from a network interface,

  • preserves the exact communication packets that are exchanged between various assets, and

  • enables network analysis and asset identification when imported into Cyber Vision Center.

PCAP file usage

To analyze traffic from your OT network, upload PCAP files to Cyber Vision Center. Use the Cyber Vision Classic UI to upload PCAP files.

When you import the file, Cyber Vision Center creates and identifies assets and associates them with their properties and communication patterns. You can then view these assets throughout the system, including on the main dashboard.


Upload a PCAP file

Upload a PCAP file to the system to analyze network diagnostic or security information.

Uploading a PCAP file allows you to review and inspect captured packet data using system analysis tools. This is typically performed during troubleshooting or forensic investigations.

Before you begin

  • Ensure you have the required permissions to upload files.

  • Have the PCAP file ready and accessible from your local system.

Procedure

  1. From the main menu, choose Admin > Sensors > PCAP Upload.

  2. Click Upload a new file.

  3. Click Choose a file or drag and drop to upload. Add the file in the box.

  4. Click Upload to start the process.

    Note

    The system displays the status for DPI and Snort during the upload.

    If you upload a large file, you can pause the upload. To resume, select the same PCAP file with the browse button and click Resume.

After you upload the PCAP file, you can analyze it in the system.

What to do next

  • Review the upload confirmation.

  • Analyze the uploaded PCAP if needed.
