Hi Sanjay and welcome to Firebird!

There is no inherent security built into Firebird. If anyone get their
hands on your .gdb-file, they don't even need to know your password to read
its content Of course, a plain copy could make the file corrupt, but
backing it up and restoring onto another system, will give SYSDBA of the
new system full access to your data.

What you can do is:

* avoid giving anyone access to the file itself.
* encrypt your data before putting them into the database
* remove source code for stored procedures etc.

This last point is just if you're afraid of anyone duplicating your system
(e.g. competitors), whereas the others are important if you want to protect
the data itself.
