Subject [jira] Commented: (DERBY-2109) System privileges
Date Mon, 18 Dec 2006 17:34:21 GMT
    [ http://issues.apache.org/jira/browse/DERBY-2109?page=comments#action_12459413 ] 
            
Dag H. Wanvik commented on DERBY-2109:
--------------------------------------

> CONCLUSIONS
> 
> 1) Using Java Security to police engineShutdown and createDatabase
>    will mean that additional privileges (doAs or doAsPrivileged) must
>    be granted not just to derby.jar but to all ProtectionDomains above
>    Derby on the call stack.

Can't this be avoided by running authentication and
doAs/doAsPrivileged inside a plain doPrivileged's PrivilegedAction? Then we
just need to allow derby.jar the "doAs/doAsPrivileged" permission? Or
is there something special about these permissions?

> 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).
