Proxy Configuration

If the Virtual Sensor is behind a Proxy server, you need to enable a Proxy configuration using the Enable Proxy menu option. Authentication (Basic) of the Virtual Sensor connection to your Proxy server can be enabled by configuring the Proxy user and password fields.

The Virtual Sensor uses Secure Sockets Layer (SSL) protocol (HTTPS) to secure its connection to the Qualys web application, in a similar way that a web browser does to a secure web server. If the Qualys connection must pass through a Proxy server, then you must enable the Proxy option on the Virtual Sensor. This configuration re-directs Qualys outbound connections through the Proxy server.

Your Proxy server must be configured to tunnel or pass through the SSL session to the Qualys web application. This ensures a secured end-to-end connection. SSL bridging or tunnel termination must not be configured in your Proxy server when supporting the Virtual Sensor.

To configure Proxy support, perform the following steps:

1. Go to Set up Network menu option.
2. Choose Proxy Configuration and press Enter to continue.
3. Select Enable Proxy and click OK.
4. When the Enter the proxy server details prompt appears, provide the proxy server parameters:
   • Proxy IP Address - Enter the Proxy server’s IP address.
   • Proxy Port - Enter the port number assigned to the Proxy server.
5. Click Next to select the authentication type from NoAuth, BasicAuth and NTLMAuth.
   If you select authentication type as BasicAuth or NTLMAuth, you need to provide user name and password.
   • Proxy User - Enter the user name for Proxy authentication. If authentication is not enabled at the Proxy level, leave the entry field blank.
   • Proxy Password - Enter the password for Proxy authentication. If authentication is not enabled at the Proxy level, leave the entry field blank.
