Security is a critical aspect of any database system, and SQL Server is no exception. Microsoft has recently published three white papers that provide valuable insights into various security-related topics in SQL Server. In this article, we will briefly discuss these white papers and their significance.
1. Engine Separation of Duties for the Application Developer
Separation of duties is an important consideration when it comes to databases and database applications. This white paper focuses on the topics that application developers should be aware of in order to achieve proper separation of duties. By defining schemas and roles effectively, a distinction can be created between users who manipulate data and those who administer the database. The paper also provides a heuristic example to guide developers in implementing separation of duties.
2. Database Encryption in SQL Server 2008 Enterprise Edition
With the introduction of transparent data encryption (TDE) in SQL Server 2008, users now have multiple options for encrypting their data. This white paper compares TDE with other encryption methods, such as cell-level encryption, Encrypting File System (EFS), and BitLocker Drive Encryption. TDE, which works at the file level, is the optimal choice for bulk encryption to meet regulatory compliance or corporate data security standards. The paper assumes familiarity with concepts like virtual log files and the buffer pool, and provides technical implementations of TDE.
3. Cryptography in SQL Server
Cryptography plays a crucial role in ensuring data security in SQL Server. However, its implementation is often not well understood, leading to incomplete or ineffective security measures. This white paper provides an overview of cryptographic functionality in SQL Server and discusses its practical applications in authentication, signed procedures, permissions, and encryption. The focus is on practical ways for database professionals to utilize cryptography in SQL Server.
By reading these white papers, SQL Server users can gain a deeper understanding of security concepts and best practices. Implementing the recommendations outlined in these papers can help enhance the security of their databases and protect sensitive data from unauthorized access.
