SQL Server is the dominant relational database in the Windows market and data security is a huge and growing concern for all businesses. Securing SQL Server is one of the most important responsibilities of the SQL Server professional.
SQL Server Distilled, Second Edition is a very carefully researched, clearly explained book on securing SQL Server, by an author who knows SQL Server inside and out. If you follow the practical guidelines that are clearly set out in this book, then you stand a very good chance of making sure that the data stored in your database is secure and that the conversation between your applications and the database is secure (preventing SQL injection attacks, etc.). For example, any database administrator who implemented the security precautions detailed in the book would not have been affected by the infamous Slammer virus.
This second edition offers practical advice on how to implement good practices that will ward off future viruses before they are even created, and it contains new content that reflects all updates to SQL Server's security mechanisms.
