Security and Authentication

Note:

In this documentation, "SSL" refers to both TLS (Transport Layer Security) and SSL (Secure Sockets Layer). The connector supports SSLv3 and TLS 1.2. The SSL version used for the connection by default is the highest version that is supported by both the connector and the server.

To protect data from unauthorized access, Netezza data stores may require connections to be authenticated with user credentials or the SSL protocol. The Simba Netezza ODBC Driver provides full support for all authentication protocols supported by your Netezza server. For information about configuring authentication on your Netezza server, see the IBM Netezza System Administrator's Guide.

If your Netezza server uses the MIT Kerberos or Active Directory Kerberos protocol, you only need to provide your Netezza user name. If your server uses a non-Kerberos authentication method such as LDAP, you must provide your Netezza user name and password. For information about how to specify your credentials for the connection, see Creating a Data Source NameCreating a Data Source Name.

In addition, the connector supports SSL connections with one-way authentication using SSL version 3.

It is recommended that you enable SSL whenever you connect to a server that is configured to support it. SSL encryption protects data and credentials when they are transferred over the network, and provides stronger security than authentication alone.
