Study Notes
Database Administration and Security
- Database security involves measures to protect databases from unauthorized access, service interruptions, and data loss.
- Data Administrator (DA) manages overall corporate data resources (manual and computerized).
- Database Administrator (DBA) maintains database environment, ensuring security, design, implementation, and maintenance.
- DA determines database contents and boundaries; DBA manages physical structures.
- DBA's tasks include designing, implementing, maintaining, and securing database structures.
- DA and DBA roles can overlap; if no DA, DBA handles both functions.
- DBA supports end-users, enforces policies, handles data backup/recovery, and monitors data usage.
SQL Security Model
- SQL security model specifies security restrictions enforced by the DBMS.
- Users are people or processes with database access and unique IDs.
- DBMS grants privileges for specific actions (e.g., SELECT, INSERT, DELETE, UPDATE) on database objects.
- Objects are database entities like tables, rows, columns, indexes.
- Privileges define user access rights to objects.
- Roles are named collections of privileges authorizing database access.
Database Users
- Security setup involves authentication and authorization.
- Users, groups, or processes access SQL server at either server or database levels.
- Server-level includes logins and server roles; database-level includes users and database roles.
Creating and Managing Logins
- Login establishes connection to SQL Server.
- Login must be mapped to a database user for database object access.
CREATE LOGIN
command creates a new login with specific password.ALTER LOGIN
modifies login name or password.- Database object access requires proper login mappings and user privileges.
Database Privileges
- Authorization controls access to database objects.
- Each object has an owner; privileges control modifications by other users.
GRANT
command provides database object access privileges to users or roles.REVOKE
command removes database object access privileges from users or roles.
Database Roles
- Roles group privileges for efficient user management.
- Roles streamline privilege assignment to multiple users.
- Database-level roles are predefined and can be customized.
- Predefined roles (e.g., db_owner, db_securityadmin) come with specific permissions.
- Assign predefined or customized user roles for effective database access management.
