Common Vulnerabilities in Database Security

Creating an enterprise security plan is a complex endeavour. It involves evaluating multiple threats that gain access through many network paths to a hodgepodge of different applications and systems. With the focus on systems and paths, databases are frequently overlooked. Securing the database should be a fundamental tenet for any security practitioner when developing his or her security plan. The database is the source of data, the "crown jewels" in the information economy. Any security effort must start with this in mind and end with the strongest level of controls applied at the database layer.

Writing Secure Transact-SQL

There are plenty of good sources of information about how to deploy SQL Server in a secure fashion. However, these resources are often targeted at database administrators tasked with securing already developed applications. In addition, there is a rich body of information that discusses writing secure .NET and ASP.NET code, including .NET code that accesses SQL Server. However, many of these resources focus on the data access code that runs on the application servers rather than the Transact-SQL (T-SQL) code that executes within SQL Server. Developing T-SQL code that runs securely on SQL Server is the primary focus of this column.

Get all from Table A that isn't in Table B

A common requirement when building a data warehouse is to be able to get all rows from a staging table where the business key is not in the dimension table. For example, I may want to get all rows from my STG_DATE table where the DateID is not in DIM_DATE.DateID.

For Loop Container Samples

One of the new tasks in SQL Server 2005 is the For Loop Container. In this article we will demonstrate a few simple examples of how this works. Firstly it is worth mentioning that the For Loop Container follows the same logic as most other loop mechanism you may have come across, in that it will continue to iterate whilst the loop test (EvalExpression) is true. There is a known issue with the EvalExpression description in the task UI being wrong at present. (SQL Server 2005 Beta 2).

File Inserter Transformation

SQL Server 2005 has made it a lot easier for us to loop over a collection and with each iteration do something with the item retrieved. In this article we are going to show you how to iterate over a folder looking at the files within and doing something with those files. In this instance we will be entering the filename into a SQL Server table and we will then load the actual files we have just found into another SQL Server table. You will note here that there is still the need to load the file names into a table as an intermediate step just as we need to do in SQL Server 2000.

Workflow Constraints (Logical OR)

To do some of the stuff we wanted in SQL Server 2000 DTS we had put together some serious glue code and to be honest it wasn't pretty. One of the things that we used to have to do this way was if we wanted to implement using workflow constraints a Logical OR. Well that has changed and it is now really simple and this article is going to show you how to implement it.
