Setting permissions on database objects can be quite complicated if you don t fully understand the implications of the settings. In general, there are several good ways to manage permissions in databases of any size: w Use roles to grant permissions. Managing roles is much easier than granting permissions to individual users. Roles should be designed based on specific job functions and should provide only necessary permissions. Create a hierarchical role system. Some users may require basic read access to specific tables, while others will require full access to some tables and only read access to others. Since roles can be contained in other roles, it might be worthwhile to create groups such as DB Basic Access, DB Intermediate Access, and DB Full Access. The intermediate role could contain Basic Access permissions plus additional permissions. Use stored procedures. Apart from security management benefits, stored procedures execute much faster than the same SQL statements executed manually, and can thus cut down on network traffic. They also make interactions with database objects easier for developers and end users. We ll talk about the performance benefits of stored procedures later in this chapter. Assign permissions on views and stored procedures. If your database contains an employee information table that includes basic information (such as employee names and employee numbers) and sensitive information (such as salary figures), you may choose to create a view or stored procedure that does not return sensitive data. As long as the view owner has access to the table, the user of the view will be able to access all of the data in the table. You can deny everyone access to the table except for the owner of the view or stored procedure. You can then grant users access to the view or stored procedure without worrying that they will query sensitive information.

Though it won t necessarily prevent users from modifying information, auditing can be a very powerful security tool. SQL Server 7 lets you automatically log actions performed by users on specific database objects. Although technically it won t prevent wrongdoing or protect data directly, auditing is a vital function of any secure database server implementation. To view auditing information, do the following: 1. Expand the Management folder for the server for which you want to view the audit logs. 2. In the SQL Server Logs folder, click the Current log to view the most recent information, or click an Archive log to view older data. 3. You can modify the view by clicking the log name and selecting View. You can also click a column heading to sort by that value. Figure 4-13 shows some sample auditing information. The information displayed includes the date and time of the logged item, the process ID that generated the event, and the text of the logged message. One of the most difficult parts of regularly reviewing audit logs is that there is a lot of information that is not necessarily

Setting Alerts
In addition to the default alerts, you can track other actions of interest. You can log specific information by configuring SQL Server alerts in the SQL Server Agent alerts option. To set an alert, do the following: 1. Expand the Management folder. Expand the SQL Server Agent folder, right-click Alerts, and select New Alert. You ll see this dialog box:
2. Name the alert and choose SQL Server Event Alert for the Type. Check the Enabled box. 3. To define the alert condition, choose to report on an error message number (which may be user-defined) or on all events that have a specific severity. You can also assign the alert to only a specific database. Finally, enter the text for the error message. 4. Optionally, you can use the settings on the Response tab to notify database administrators of problems. Click OK to accept the settings.
