Ok, then the documentation needs to be updated. As written it is a *tad*

Define "too weak".

If you're talking about an encrypted database, then yes. If you're talking
about transport layer security, then maybe not.

Being a paranoid DBA, I'm all for strong security like some of the newer
features introduced IBM's IDS 11 (That's the old Informix database).
However, I'm also practical.
When applying security, you need to take a look at the entire system, use
case and potential threats.

It is interesting is that you have Sun's view of the world and IBM's. IBM is
"pushing" their DRDA in to all of their products and are writing their front
end tools/adaptors to this specification, such that RoR, Java, Python and I
think Perl will be able to use a common adaptor to touch all of their
databases. (Read DB2[i,z,luw], and IDS) Not sure how Cloudscape/Derby fits
in with their strategy since they're dropping support in 2008.

Is Sun and/or the community going to support DRDA for Derby/JavaDB?
