HTTPS Recommended
When administrative security is enabled on the local license server, the use of HTTPS is strongly recommended to protect license server data being transmitted during administrative operations. (To use the HTTPS protocol, you must enable it on your license server machine.) For more information, see Base URL for the License Server.
Optionally, you can use the security.http.auth.enabled license server policy to enforce the use of HTTPS when administrative security is enabled. See Administrative Security Policies on the License Server for details.
