David Allsopp commented on CASSANDRA-2274:
------------------------------------------
D'oh, I hadn't realized encryption was implemented now! Spent too much time on
old versions...
@Richard - Dropping a keyspace is a Thrift operation, and I think you can
already define different levels of access for 'normal' read/write access versus
'dangerous' schema operations.
The crux of the above issue, however, is that inter-node messaging is separate
from the Thrift communications - so even with Thrift authentication enabled, a
node can join the cluster and read data. Presumably the inter-node encryption
fixes this.
Verifying IP addresses might still be useful as per the sub-issue, but it's a
minor point if proper encryption is in place.

> 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.
