Tivoli Workload Scheduler provides a secure, authenticated, and encrypted connection mechanism for communication based on the Secure Sockets Layer (SSL) protocol, which is automatically installed with Tivoli Workload Scheduler.
Tivoli Workload Scheduler also provides default certificates to manage the SSL protocol that is based on a private and public key methodology.
If you do not customize SSL communication with your own certificates, Tivoli Workload Scheduler uses the default certificates that are stored in the default directories to communicate in SSL mode.
