hi i would like to know is there any possible ways that i can protect
my firebird database from unauthorised user.

currently the database (*.fdb) is stored in a networked pc. alot of
people have the access to it. but not all of them has the right to
access it. due to lack of security anyone can just copy out the fdb
any open it up at their workstation or home.

is there any way that i can protect this? either directly protect the
data (encryption) or the database?
