If you want to use the secure HTTPS protocol instead of the HTTP protocol, you only need to change the URL for starting the PPM front-end as follows.
https://<loadbalancer>:<loadbalancer-https-port>/ppm/html
Example
https://localhost:4443/ppm/html
The HTTPS protocol is already activated in load balancer and can be used without changing the configuration. By default, a signed certificate generated by the load balancer is used for HTTPS support. Most browsers do not support it, however, because it does not contain any valid root certificate of an approved certification authority. The PPM Operation Guide describes how to create a valid certificate for HTTPS support of the load balancer.
Using the HTTPS protocol for the load balancer secures all communication between the PPM front-end and the PPM server. The PPM Operation Guide describes how to encrypt RMI data communication between the PPM server components.
