Password protect a SQL database

I have almost completed an application using VB Express 2005 that connects to a SQL Express 2005 database. This will be a single user environment. I want to password protect the database so that the application (which will know the password) can connect to it but if somebody copies the database from the application directory and tries to open it themselves, they will need the password to do so. Using VB 2005 I cannot find a way to add the password to the database.

Once I add the password to the database, do I simply need to modify the connection string with this password so the application can talk to the database without being prompted for a password?

Thanks.

Anyone with ADMIN rights to the PC can copy the mdf/ldf and attach it to another server - you cannot protect the mdf/ldf from a person with these rights - there is no database password in MS SQL.

So in Access where I could simply go to tools, security, set password...the new latest and greatest SQL Server doesn't have password protection? If they took it away, anything easy I can do instead? Again, it's a single computer environment that lots of people will use without any login required for the computer.

Hi ghall426;

This is a quote from Microsoft about this product....

In addition, like the other members of the SQL Server 2005 product line, SQL Server 2005 Express has the ability to encrypt database data, thereby ensuring that sensitive data can be accessed only by users who have the appropriate permissions. SQL Server 2005 Express supports both symmetric and asymmetric data encryption.

Some additional research may might allow you to determine if this could be implemented in your situation.

Hopes this helps.

From what I have seen, the security in all versions of SQL Server are far superior to those in Access (I have a 8 line VB program to give you the password for an Access file ;) ).

While the Admin access to SQL Server is not ideal in all situations, there are ways of blocking it (unfortunately I can't remember them :( ); on a well-structured network this isn't a problem, but obviously if all users are Admins then it is.

With Access, anybody who can search the web can get either the source code for free (if they know what to look for, and I'm not telling!), or a pre-written program for a low price.
