Is it possible to password protect an SQL server database?

Question

Is there any way to password protect an SQL server database without using commercial third party tools? What can help me achieve this?

Answer 1

In SQL Server 2008, you have transparent data encryption which allows you to set a password and certificate so that MDFs and Backups can not be restored or attached without the correct password/certificates.
