Martin Zaun commented on DERBY-2109:
------------------------------------
Rick,
thanks for the summary on the backward compatibility issues, which only arise,
as you've correctly described, under both, A) and B).
For 100% completeness, I'd have two technical additions:

...and to run the security checks themselves (which require an AuthPermission,
a PropertyPermission, and a FilePermission -- see template.policy).

... and
3) If the customer shuts down the engine via a connection URL with
"shutdown=true;", then the customer will also need to supply credentials, i.e.,
user/password attributes in the URL.

Good summary. Thanks, Martin

> Add mechanisms for controlling system-level privileges in Derby. See the
> related email discussion at
> http://article.gmane.org/gmane.comp.apache.db.derby.devel/33151.
> The 10.2 GRANT/REVOKE work was a big step forward in making Derby more
> secure in a client/server configuration. I'd like to plug more client/server
> security holes in 10.3. In particular, I'd like to focus on authorization
> issues which the ANSI spec doesn't address.
> Here are the important issues which came out of the email discussion.
> Missing privileges that are above the level of a single database:
> - Create Database
> - Shutdown all databases
> - Shutdown System
> Missing privileges specific to a particular database:
> - Shutdown that Database
> - Encrypt that database
> - Upgrade database
> - Create (in that Database) Java Plugins (currently Functions/Procedures,
> but someday Aggregates and VTIs)
> Note that 10.2 gave us GRANT/REVOKE control over the following
> database-specific issues, via granting execute privilege to system
> procedures:
> Jar Handling
> Backup Routines
> Admin Routines
> Import/Export
> Property Handling
> Check Table
> In addition, since 10.0, the privilege of connecting to a database has been
> controlled by two properties (derby.database.fullAccessUsers and
> derby.database.defaultConnectionMode) as described in the security section of
> the Developer's Guide (see
> http://db.apache.org/derby/docs/10.2/devguide/cdevcsecure865818.html).
