Configuring security settings

About this task

By default, the endpoint ports from all services are available in the domain on HTTP protocol and access control is not enforced. You can enable the Hypertext transfer protocol secure (HTTPS) as a default connection protocol by following the steps in the Procedure section.

Procedure

  1. Open browser and type https://<FQDN_of_zUnderstand_container>/ad/admin and go to Configure > Environments > "Your environment" > Servers and security > Security. The Security settings page is displayed.
  2. Select a protocol type.
    Note: If you select HTTPS as a connection protocol, both TLS 1.2 and TLS 1.3 are supported.
  3. If you do not have custom certificates, then you can select the Self signed certificate files. This option displays the default certificate that is used in WebSphere Liberty profile service and Authentication Server (DEX) and configures all other IBM ADDI services to use the same certificate.
    1. If the certificate is expired or a new Fully Qualified Domain Name (FQDN) has been defined on the machine, then you can regenerate the certificate by checking the Generate new self signed certificate files option.
    2. Once the option is selected, a new field is displayed to enter the new keystore password reveal.
    3. Click Save.
  4. Click OK when a confirmation dialog is displayed. The saving process takes several minutes.
  5. Note: If you encounter a Page not found message while reloading the browser, this means that the service is still restarting. You can try reloading the page after a minute and then you can repeat the process as required.
    Once the process is complete, an alert dialog appears prompting you to restart the browser. This happens because the browser does not yet recognize or trust the newly installed certificate, resulting in an untrusted certificate warning that blocks the access to all the pages within the IBM Z Understand Configuration Service Admin.
