Enable 'require_ssl' Cluster Parameter


Amazon Redshift supports Secure Sockets Layer (SSL) connections to encrypt data and server certificates to validate the server certificate that the client connects to.

By default, cluster databases accept a connection whether it uses SSL or not. To configure your cluster to require an SSL connection, set the require_ssl parameter to true in the parameter group that is associated with the cluster.

For further information about AWS Redshift SSL support refer to the AWS Redshift documentation.


Enforce TLS/SSL on your Redshift cluster to keep your data secure in transit by encrypting the connection between the clients and your clusters.
