Daniel John Debrunner commented on DERBY-2196:
----------------------------------------------
Rick> 2) I had to broaden the socket accept privileges to all port numbers.
This is because, after accepting a connection request on the distinguished
port, the server then opens up a connection with the client on another port,
whose number is unpredictable.
Should the permission then be broken into two, one for the accept on the
distinguished port, and then connect(?) on all ports or a range of port
numbers?
> Run standalone network server with security manager by default

> From an e-mail discussion:
> ... Derby should match the security provided by typical client server
> systems such as DB2, Oracle, etc. I
> think in this case system/database owners are trusting the database
> system to ensure that their system cannot be attacked. So maybe if Derby
> is booted as a standalone server with no security manager involved, it
> should install one with a default security policy. Thus allowing Derby
> to use Java security manager to manage system privileges but not
> requiring everyone to become familiar with them.

> PROTECTED]
> I imagine such a policy would allow any access to databases under
> derby.system.home and/or user.home.
> By standalone I mean the network server was started though the main() method
> (command line).
