Launch a Virtual Network Sensor instance on Oracle Cloud Infrastructure

Procedure

1. Specify Virtual Network Sensor deployment settings and download the Virtual Network Sensor image from Trend Vision One.
   1. In the Trend Vision One console, go to Network Security → Network Inventory → Virtual Network Sensor.
   2. Click Deploy Virtual Network Sensor.
      The Virtual Network Sensor Deployment panel appears.
   3. Select Oracle Cloud Infrastructure for the platform.
   4. Click Download Disk Image to download the Virtual Network Sensor image and extract the image from the downloaded file.
   5. Set the Admin password and confirm the password.
      The password must contain the following:

      • 12 to 32 characters
      • Both uppercase and lowercase characters
      • At least one number (0-9)
      • At least one special character: ~!`@#$%^&*()/_+=[]{}-\|<>',.?:;" or space

      Note This step is used to set the default admin password to access the Virtual Network Sensor command line interface after deployment.

   6. Select the Connection method.
      • Direct connection: the Virtual Network Sensor connects to Trend Vision One directly. Make sure the Virtual Network Sensor is able to connect to the internet when using this configuration.
      • Connect using a custom proxy: the Virtual Network Sensor connects to Trend Vision One through a third-party proxy. After choosing this method, configure the following fields:
        • Proxy address: Specify the IP address of the proxy.
        • Proxy port: Specify the connecting port of the proxy.
        • Proxy server requires authentication: (Optional) Select if the proxy requires authentication credentials.
          • User name: Specify the user name for the proxy credentials.
          • Password: (Optional) Specify the password for the proxy credentials.
      • Connect using a Service Gateway as proxy: the Virtual Network Sensor connects to Trend Vision One through a Service Gateway. Select a Service Gateway to use for this method.

        Important The Virtual Network Sensor must be able to connect to a Service Gateway with the Forward Proxy Service configured and enabled. For more information, see Manage services in Service Gateway.
