Hello,

thanks for your answers and proposals, my problem is effectively for
distribute a product based on FireBird or Interbase
and protect structure from access
my only problem is the SYSDBA account, it's the only weakness of security,
but as one cannot remove the SYSDBA user,
my data base remains accessible to all that can copy my fdb file despite
username and password !

For an other way, any can say me if it's exist an trigger or event when a
user connect on database that call a script ? this
simple way allow to protect all fdb file's from any intrusion !!!! with this
simple connect function I have the solution for efficient
protect my fdb files

Thanks for your help
