----------------------------------------------
For the record, I still think this is really iptables' job.

> It's possible for a node to join an existing cluster (with perhaps more
> stringent security restrictions i.e. not using AllowAllAuthentication) and
> issue destructive commands that affect the cluster at large (e.g. drop
> keyspace via cassandra-cli, etc).
> This can be circumvented with a pluggable security module that could be used
> to implement basic node vetting/identification/etc.
