Description
SQL server is the most widely used database platform in the world, and a large percentage of these databases are not properly secured, exposing sensitive customer and business data to attack.
In Securing SQL Server, 2e, readers learn about the potential attack vectors that can be used to break into SQL server databases as well as how to protect databases from these attacks. In this book written by Denny Cherry, a Microsoft SQL MVP and one of the biggest names in SQL server today, readers learn how to properly secure a SQL server database from internal and external threats using best practices as well as specific tricks the authors employ in their roles as database administrators for some of the largest SQL server deployments in the world.
"Denny Cherry is what would happen if Bill Gates and AC/DC got together to create a sibling. He's a bare-knuckles, no holds-barred technologist, and you can bet that if he tells you that something does or doesn't work, he's speaking from experience. Active in the community, his passion is sharing. You'll enjoy this book."--Buck Woody, Senior Technology Specialist, Microsoft

"Securing SQL Server - Protecting Your Database from Attackers and SQL Injection Attacks and Defense are two new books out on SQL security. The first, Securing SQL Server - Protecting Your Database from Attackers, author Denny Cherry takes a high-level approach to the topic. The book explains how to secure and protect a SQL database from attack. The book details how to configure SQL against both internal and external-based attacks. This updated edition includes new chapters on analysis services, reporting services, and storage area network security. For anyone new to SQL security, Cherry does a great job of explaining what needs to be done in this valuable guide. In and SQL Injection Attacks and Defense, editor Justin Clarke enlists the help of a set of experts on how to deal with SQL injection attacks. Since SQL is so ubiquitous on corporate networks, with sites often running hundreds of SQL servers; SQL is prone to attacks. SQL injection is a technique often used to attack databases through a website and is often done by including portions of SQL statements in a web form entry field in an attempt to get the website to pass a newly formed rogue SQL command to the database. SQL injection is a code injection technique that exploits security vulnerability in a website's software. The vulnerability happens when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. With that, the need to defend servers against such attacks is an imperative and SQL Injection Attacks and Defense should be required reading for anyone tasks with securing SQL servers." --RSA Conference
