title: Prevent Firebird database access on other server with different username/password
body: <p>I created a Firebird database by an account other than sysdba. If I put a copy of this db to another machine, I can open it by sysdba account and the 'masterkey' password. Thus this is real risk if some one can take a copy of it.</p>
  
  <p>Is there some way to prevent this scenario?</p>
