Steps to do after DBDefence installation

Database encryption

Accessing protected database

Effectively encrypts entire database

Existing 3rd party encryption solutions for SQL Server use extended procedures to call functions in DLLs. The call to outside for SQL Server is very resource expensive. Additionally such procedures can't handle large binary types. Our solution uses completely different approach. You do not need to call UDFs to encrypt values. Instead SQL Server encrypts all information which comes to the protected database. Does not matter which type or what table. Does not matter is it data or stored procedure.

Typical error message accessing protected database:

Works transparently

DBDefence does not use UDFs for encryption. So you do not need to wrap any fields into UDF calls. Everything in the database encrypted automatically. To unlock access to the database you need to execute one SQL statement with the correct password.

Hides schema of the database

DBDefence protects system tables as well so you can't access database or even browse it's catalog.

Possible to encrypt databases for 3rd party applications

Suppose you have a 3rd party application and you do not have the source code or can't insert unlocking SQL statement. In this case it is possible to intercept database connection. After successful login to the protected database whole application works as usually.

Passwords not traceable with the profiler

Currently calls to extended procedures of 3rd party encryption solutions can be traced with the Profiler. Adiministrator can catch the password easily. DBDefence uses OPEN MASTER KEY statement which is not displayed by the Profiler.

Supports SQL Server 2005, 2008 and SQL Express

DBDefence supports SQL SQL Server 2005, 2008 and SQL Express on X86 and X64 Platforms.

Easy integration into existing projects.

To install DBDefence on the client side you need to copy blockkk.dll, set one key in the registry and run very short SQL script on the target SQL Server. Such easy steps can be done from any installer systems.

Secure database distribution

You can create the database, protect it and include in your installer. In the installer, you install DBDefence and attach protected database with a single CREATE DATABASE .. FOR ATTACH statement. Database schema and data never exposed to DBA.
