If not configured during setup, you can enable a secure HTTPS Connection Handler and authentication using dsconfig.

Note:

By default, the PingDataMetrics server can open up to 20 simultaneous database connections. The HTTP Connection handler that runs the REST API servlet has a default value of 15 connections. If the PingDataMetrics server receives requests through multiple HTTP Connection Handlers, make sure that the total number of request handlers does not exceed the maximum number of database connections.

When authentication is enabled, the REST API service requires HTTP basic authentication. Requests are authenticated against entries in the api-users LDIF backend, or entries in cn=Root DNs,cn=config. Root distinguished name (DN) users have many privileges by default. To restrict access, authenticate with users in the api-users backend instead, to prevent the unnecessary use of more privileged account credentials.
