Tungsten Cluster supports SSL, TLS and certificates for both communication and authentication for all components within the system, and to the underlying databases. This security is enabled by default and includes:
Authentication between command-line tools (cctrl), and between background services.
SSL/TLS between command-line tools and background services.
SSL/TLS between Tungsten Replicator and datasources.
SSL/TLS between Managers and datasources.
SSL/TLS between Tungsten Connector and datasources.
SSL for all API calls.
File permissions and access by all components.
If you are using a single staging directory to handle your complete installation, tpm will automatically create the necessary certificates for you. If you are using an INI based installation, then the installation process will create the certificates for you, however you will need to manually sync them between hosts prior to starting the various components.
It is assumed that your underlying database has SSL enabled and the certificates are available. If you need, and want, this level of security enabling, you can refer to Section 5.14, “Enabling Database SSL” for the steps required.
Due to a known issue in earlier Java revisions that may cause performance degradation with client connections, it is strongly advised that you ensure your Java version is one of the following MINIMUM releases before enabling SSL:
