▪The cache and backend databases are protected by a traditional authentication mechanism in which a user has to provide a valid user ID and password combination to connect to a database. You can also use the operating-system-based external authentication mechanism available with solidDB^®.

▪The user account that is used for the IBM InfoSphere CDC instances to access the databases has to have sufficient privileges to access and modify the data and metadata. A database administrator username is recommended.

▪The IBM InfoSphere CDC instances uses scrambling to store the user names and passwords, that is, the authentication data is encrypted using a weak encryption method.

▪The traffic between the IBM InfoSphere CDC replication engines and the databases is encrypted in all cases. The encryption is provided, or available, in the database-specific JDBC drivers.

▪The traffic between IBM InfoSphere CDC replication engines is unencrypted.
