Setting Username and Password For Cassandra database
cassandra
Solution
You can create users with passwords that have ro or rw access at the column family level. For Cassandra 0.7 or earlier, you can find an overview here: http://www.datastax.com/docs/0.7/configuration/authentication
For 1.0 and later, authentication was moved into the examples directory. You can find an example of how to configure it (same as before) here: http://devblog.michalski.im/2012/04/05/adding-simple-authentication-to-cassandra/
In general, Cassandra developers seem to recommend segregating your Cassandra database via firewall over relying on user/pass authentication. If you can go this route, it's much preferred.
For additional security, you can also encrypt inter-node communication: http://wiki.apache.org/cassandra/InternodeEncryption
