Hi Pri,

If you grant someone file system access to either a firebird database
file or a firebird backup, then they can make themselves a SYSDBA.
Read Geoff Worboys paper which addresses this and several other issues.

If your security requirement means that "No matter people
can copy the database, if they cannot open it", then embedded is not a
good choice. A terminal services delivery model is a good way to get
the ease of deployment with the security of no filesystem access to
the database by untrusted users.
