Using encryption requires that you issue certs, so inherently you are becoming
a CA when you use it.

If your requirement for this function is that you must be your own CA then I
would agree it will work, however, if you are required to use an external CA
like VeriSign or GeoTrust anyone who has the ability to obtain a certificate
will be able to get into your system.
> Restrict Cassandra cluster node joins to a list of named hosts

> Key: CASSANDRA-2274
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2274
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.7.2
> Environment: All
> Reporter: Andrew Schiefelbein

> Because firewalls and employees are not infallible it would be nice to
> restrict the ability of any node to join a cluster to a list of named hosts
> in the configuration so that someone would be unable to start a node and
> replicate all the data locally. I understand that in order to do this the
> person must know the seed servers and the cluster name and to extract the
> data they will need a userid and password but another level of security would
> be to force them to execute any brute force attack from a locked down server
> instead of replicating all the data locally.
