Subject [jira] Commented: (DERBY-2109) System privileges
Date Fri, 14 Mar 2008 18:14:24 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12578880#action_12578880

Martin Zaun commented on DERBY-2109:
------------------------------------

While NetworkServerControl authentication was a missing security feature that 2109 attempted
to address, there were a couple of unresolved questions at the time of the decision to postpone
some of the 2109 until after 10.4, for instance:

- If I remember correctly, there was a discussion how NSC authentication relates to JMX, which
has its own authentication mechanism; a question was if we then require two authentications,
one by JMX and another one by NSC, or if NSC in this case does not do its own authentication
check for shutdown. But I'm not sure remember this topic correctly.

- Should we require user credentials for network server startup when running with authentication
or should NSC not check user credentials upon shutdown when the server was started without
ones? (Or should we have a default identity "APP" like with jdbc clients?)

When browsing through the committed parts of the patch, it slipped my attention that the authentication
check in NetworkServerControlImpl was still in effect (unlike the check for authorization).
If we decide to disable them for 10.4 it can be very easily done by making checkShutdownPrivileges()
a dummy method (and keeping the remaining code for user credentials support).

> 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).
