VMware strongly recommends that you configure SSL certificates for authentication of View Connection Server instances, security servers, and View Composer service instances.
A default SSL server certificate is generated when you install View Connection Server instances, security servers, or View Composer instances. You can use the default certificate for testing purposes.
Replace the default certificate as soon as possible. The default certificate is not signed by a Certificate Authority (CA). Use of certificates that are not signed by a CA can allow untrusted parties to intercept traffic by masquerading as your server.
