SQL Security: Roles and Permissions

Create and Assign a Role

Create a role named 'data_analyst' with SELECT permission on the 'Customer' table and assign it to a user named 'analyst_user'.

Expected output: A role 'data_analyst' with SELECT permission on 'Customer' and assigned to 'analyst_user'.

Hint: Use CREATE ROLE, GRANT, and sp_addrolemember or ALTER ROLE commands.

Review and Audit Roles

List all roles in your database and the permissions assigned to each role.

Expected output: A report showing roles and their permissions.

Hint: Use system views like sys.database_principals and sys.database_permissions.

A permission is a specific right to perform an action on a database object, such as SELECT or INSERT. A role is a collection of permissions that can be assigned to users to simplify access management.

Roles simplify permission management by grouping permissions, making it easier to assign, modify, and audit access rights consistently across multiple users.

It means granting users only the minimum permissions necessary to perform their tasks, reducing the risk of unauthorized access or accidental data modification.
