The VPC Access page of the Cloud Firewall console provides real-time information about traffic between virtual private clouds (VPCs). This way, you can detect suspicious traffic and mitigate risks at the earliest opportunity. The VPC Access page provides statistics on the traffic, IP addresses, sessions, ports, and assets involved in communications between VPCs.


The required VPC firewall is enabled. Otherwise, the VPC Access page does not provide traffic analysis data.

For more information about how to enable a VPC firewall, see Activate Cloud Firewall.

    • Ranking of IP Addresses by Traffic: You can view the top 10, 20, or 50 IP addresses with the highest traffic. You can also view the details of inbound and outbound traffic for each IP address.
    • Ranking of Sessions Between VPCs by Visits and Traffic: You can view the ranking of sessions between VPCs. You can also view the traffic volume, session type, number of sessions, and ports for each type of session.

      In the Rankings of Sessions Between VPCs by Visits and Traffic section, you can click View in the Ratio column to view the proportions of ports in a specific type of session.

    • Open Ports by Traffic: You can view the proportions of all open ports.
    • Open Ports and Assets: You can view the details of traffic between VPCs. The details include basic information about open ports and your assets.

      You can click the Download icon in the upper-right corner above the port or asset list to download the open ports or assets to a CSV file to your computer for check and analysis.
