Subject [jira] Commented: (DERBY-2109) System privileges
Date Fri, 18 Jan 2008 20:58:34 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12560541#action_12560541
] 

Rick Hillegas commented on DERBY-2109:
--------------------------------------

The wildcarded Principal name is only needed for the case that we want to grant privileges
to principals of the form *@databaseName (or PUBLIC@databaseName). If we agree that we aren't
going to use the policy file to regulate privileges at the database level, then the existing
policy file syntax will cover the remaining wildcard case (the system-wide wildcard) as John
and Martin have pointed out:

grant {
  // grant any user to shutdown the engine
  permission org.apache.derby.security.SystemPermission "shutdownEngine";

  // grant any user to create databases anywhere
  // (to succeed actual locations require additional file permission grants)
  permission org.apache.derby.security.DatabasePermission "directory:<<ALL FILES>>",
"create";
};

By eliminating the two special characters, * and @, we eliminate most of the escaping cases.
And we don't need to specify PUBLIC in the policy file. If SystemPrincipal represents a system-wide
UserName, then I think we clear up a lot of the confusion.

> 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).
