Benjamin Coverston commented on CASSANDRA-6018:
-----------------------------------------------
Perhaps what we really need here is a hook for a filter chain on the commit
log. CASSANDRA-4148 would also need something like this.
> Add option to encrypt commitlog

>
> We are going to start using cassandra for a billing system, and while I can
> encrypt sstables at rest (via Datastax Enterprise), commit logs are more or
> less plain text. Thus, an attacker would be able to easily read, for example,
> credit card numbers in the clear text commit log (if the calling app does not
> encrypt the data itself before sending it to cassandra).
> I want to allow the option of encrypting the commit logs, most likely
> controlled by a property in the yaml.
