Schema-Based Access Control for SQL Server Databases

Schema-Based Access Control for SQL Server Databases explores the importance of implementing effective access controls in database systems. The article highlights the principle of least privilege, emphasizing that all users, including Database Administrators (DBAs), should only have permissions relevant to their job. It introduces a structured schema-based approach to access control using ANSI SQL permissions hierarchy and database roles. This approach simplifies assigning permissions and ensures that users inherit the necessary privileges at the schema level. The article also references the role-based security in SQL Server, allowing permissions to be assigned to roles or groups of users rather than individual users. It provides insights into fixed server and fixed database roles and their predefined permissions. By mapping logins to database user accounts and adding them to appropriate roles, effective access control can be achieved in SQL Server databases.
