Security and Authentication
To protect data from unauthorized access, Redshift data stores require all connections to be authenticated using user credentials. Some data stores also require connections to be made over the Secure Sockets Layer (SSL) protocol, either with or without one-way authentication.
The Simba Amazon Redshift JDBC Driver provides full support for these authentication protocols. For detailed configuration instructions, see Configuring Authentication and SSL.
The SSL version that the connector supports depends on the JVM version that you are using. For information about the SSL versions that are supported by each version of Java, see "Diagnosing TLS, SSL, and HTTPS" on the Java Platform Group Product Management Blog: https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https.
Note:
The SSL version used for the connection is the highest version that is supported by both the connector and the server, which is determined at connection time.
