In this chapter, all aspects of security will be discussed. Logins and Users will be covered, as well as SQL Server 2008’s built-in roles. Some new features are available for policy management. This chapter will also review user roles and schemas, as well as the pros and cons of granting access to objects. The tradeoff between more granular security and less granular security will be discussed. SQL Authentication will be covered in great detail, along with the pros and cons of each method. The SQL Server Surface Area Configuration tool will be covered as well as the provisioning of the accounts used for SQL Server Services. Principals As we begin to look at SQL Server 2008 security management, a good place to start is to define what SQL Server considers a principal. Principals are entities that can request SQL Server resources and their scope of influence depends on the definition scope of the principal. Windows-level principals have a Windows permission scope, SQL Server-level principals have server-level permissions and Database-level principals have database-level permissions. A Security identifier (SID) is assigned to every principal. The following shows the hierarchy of SQL Server 2008 principals and how logins and database users can be mapped to security objects. Fixed server and database roles are not shown here but are discussed in the next section. Te s T Da y Tip Make sure that you are familiar with this hierarchy and how the principals can be mapped.

Server-level roles are fixed roles that have a serverwide permission scope.
