Configure USM Appliance to Use a Proxy

Applies to Product: USM Appliance™ LevelBlue OSSIM®

By default, USM Appliance does not need to go through any proxy server, so proxy configuration is disabled. However, should you need to use a proxy in your environment, USM Appliance provides two options: manual (external) and alienvault-proxy (built-in), for proxy configuration.

If your company requires all network traffic to go through a proxy server before reaching the Internet, you can configure the proxy in USM Appliance.

To configure USM Appliance to use an external proxy

  1. Connect to the LevelBlue Console through SSH and use your credentials to log in.

    The LevelBlue Setup menu displays.

  2. Select System Preferences.
  3. Select Configure Network.
  4. Select Proxy Configuration.
  5. Click manual, or move the cursor to manual then press the spacebar, to make your selection.
  6. Type the user name for the proxy.
  7. Type the password for the proxy user. The password will not be displayed.
  8. Type the port number used by the proxy.
  9. Type the IP address or hostname of the proxy.
  10. Press <Back> until you are on the LevelBlue Setup menu again. Select Apply all Changes.

  11. Press <Yes> to confirm.

    USM Appliance applies the changes and restarts all the services, which may take several minutes.

Additionally, USM Appliance includes a built-in proxy that you may find useful, especially if you have more than one USM Appliance deployed. You can dedicate a USM Appliance All-in-One or USM Appliance Server to be the proxy server and the other USM Appliance instances will go through it to reach the Internet. For example, you can use this setup to control how updates are received from LevelBlue. Only the dedicated USM Appliance (the proxy) downloads the updates from LevelBlue, the other instances download the updates from the proxy instead, increasing performance and security.

You need to perform the same configuration in every USM Appliance instance deployed in your network.

To configure USM Appliance to use its built-in proxy

  1. Connect to the LevelBlue Console through SSH and use your credentials to log in.

    The LevelBlue Setup menu displays.

  2. Select System Preferences.
  3. Select Configure Network.
  4. Select Proxy Configuration.
  5. Click alienvault-proxy, or move the cursor to alienvault-proxy then press the spacebar, to make your selection.
  6. Press <Back> until you are on the LevelBlue Setup menu again. Select Apply all Changes.

  7. Press <Yes> to confirm.

    USM Appliance applies the changes and restarts all the services, which may take several minutes.
