Subject [jira] Commented: (DERBY-2109) System privileges
Date Wed, 27 Feb 2008 17:49:51 GMT

Daniel John Debrunner commented on DERBY-2109:
----------------------------------------------

I'm prepared to commit this patch but I think there are a number of follow changes that would
need to be done before a 10.4 release is made. I guess if it's committed to trunk then it
can always be backed out from the branch if it doesn't seem ready for release.

 - figuring out the principal names in the policy files - I'd be interested to see the implementation
of SystemPrincipal you used to try and implement the required functionality

 - related to the previous one is having more time to understand this:
+            // An alternative approach of normalizing all names within
+            // SystemPrincipal has issues; see comments there.
+            principals.add(new SystemPrincipal(user));
+            principals.add(new SystemPrincipal(getAuthorizationId(user)));

>From a security point of view does this have the potential to allow one user to piggy
back on the permissions of another user?

 - ensuring the new security objects that are serializable have serialization ids to ensure
compatibility across releases

 - making the  new security objects final

Thanks for working on the functionality through many patches!

> 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).
