A user needs access to the client computer, operating system, and network on which the server is located. Usually, this access is the responsibility of technical support specialists or network administrators. However, in smaller environments, this responsibility may fall to a DBA or developer instead.

The first level of security that pertains strictly to SQL Server allows a client to access a server. This security level is always the responsibility of database administrators. SQL Server supports three security models: SQL Server Authentication Requires a login and password from each user. These may be different from his or her network login and password and may be different from one instance of SQL Server to another. This model was the first to be developed; it was implemented by Sybase. Before SQL Server 7.0, it was called standard security. In fact, in SQL Server 7.0 and SQL Server 2000, it is not possible to configure a server to work in this mode only. If SQL Server Authentication is needed, the DBA should configure the server to use mixed model security. Windows NT/2000 Authentication Introduced by Microsoft, it allows SQL Server logins and passwords to be based on Windows NT network logins and passwords. This practice is easier for both the user (who has to remember only one login and password combination) and the administrator (who can manage all logins and passwords centrally). Before SQL Server 7.0, it was called integrated security. Mixed model SQL Server and Windows NT/2000 Authentication A combination of the previous two models, it allows some users to log in with their network account while allowing other users (who may or may not have a Windows account) to use their SQL Server login.

Access to a server does not automatically provide a user with access to a database. An administrator has to assign a database to a login in one of the following manners: The administrator creates a database user that corresponds to the login in each database to which the user needs access.

The administrator configures a database to treat a login/database user as a member of a database role. Such a user inherits all permissions from the role. The administrator sets a login to use one of the default user accounts: guest or database owner (dbo). Once access to a database has been granted, the user can see all database objects because the object definitions are stored in system tables to which every user has read access.
Permissions
Permissions are the final level of SQL Server security. To have access to user-defined database objects, a user has to have permissions to perform actions on them. There are three types of permissions in SQL Server: Object permissions Allow a user to read and change data and execute stored procedures Statement permissions Allow a user to create and manage database objects Implied permissions Allow members of fixed roles and owners of database objects to perform activities that are not part of the object or statement permissions Roles Users can be granted permissions individually or as members of a database role. Roles are the SQL Server equivalent to groups in Windows NT or roles in Microsoft Transaction Server. In earlier versions of SQL Server, a user could belong to only one role. This restriction led to some pretty unrefined security solutions. A user can now be a member of many database roles. Therefore, roles can be used to provide a sophisticated security model, managing access to the required functionality and database objects. Object Permissions The following table indicates which object permissions are applicable to which database objects: Stored Procedure User-Defined Function Column
