Client - Server / Distributed Database security

I am seeking information pertaining to client - server database security, and am at present looking for an article entitled.

"Distributed Database Security, Computers & Security, 1994, by D.Harris & D.Sidwell"

I would also appreciate any information regarding client - server / distributed database issues, and how oracle & ingres (any client - server database) tools tackle various issues involved in distributed / Client - server database security.

Thanks, Brian.
