All connections to the ZENworks Object Store are secured through SSL. However, all connections from the ZENworks Server to the ZENworks Data Store are not secure because they use an unencrypted JDBC connection. You might want to take precautions to ensure that the connections between all ZENworks Servers and the ZENworks Data Store are as secure as possible. For example, you might want to use a private network for all communications between the ZENworks Server and its Data Store.
ZENworks administrator credentials are stored in the ZENworks Object Store. No administrator credentials are stored in the Data Store, which ensures that they are not passed as clear text.
