SSL Settings

It provides functionality to support SSL offloading based on configurations.

Overview​

As many applications are running over HTTPS, for the WAF / ADC solution to inspect user payload, it is necessary to decrypt SSL/TLS traffic. The following settings allow users to configure SSL offloading based and optional re-encryption in Haltdos solution. The performance of SSL offloading will vary based on chosen model.

SSL Settings

How to Use:​

  1. Go To WAF > Listeners > SSL Settings
  2. Configure Your Settings
  3. Click Save Changes.

Encrypt Traffic to Upstream​

This specifies WAF should re-encrypt traffic before sending it to the back-end web application.

Note

We can listen to non-HTTPS traffic and send it as HTTPS traffic to the back end server.

This option specifies if the WAF should enable HTTPS traffic for the configured website.

    Accepted values: Enable / Disable

    Accepted values: Select the uploaded SSL Certificate 

    Default: Blank
SSL Ciphers​

It is a set of algorithms or a set of instructions/steps that helps to establish a secure connection between two entities — usually the client (a user's browser) and the web-server they're connecting to (your website). Users can select respective ciphers from the drop-down.

SSL Ciphers Suites​

SSL Session Timeout​

This option allows users to specify the SSL session timeout in minutes for every HTTPS request on the listener.

    Accepted values: Integer
