SQL Database Security - Authorization

Introduction

Authorization is a crucial aspect of database security, ensuring that only authorized users and applications can access and manipulate data within the database.

This page covers the fundamental concepts and how we handle user permissions.

User Roles

We have defined several user roles:

• Admin: Full access to all data.
• Editor: Can create, modify, and delete data.
• Viewer: Can only view data.

These roles define the level of access each user will have.

Authorization Process

Each user request is processed through a series of checks:

• Check User ID: Does the user have the necessary permissions for the request?
• Check Role: Is the user assigned to the correct role?
• Check Data: Is the requested data within the allowed scope?

The system will return a response indicating success or failure based on these checks.

Example Scenario

User requests to view employee data.

The system verifies the user's role. The user is authorized to view employee data. The response will be: 'Access granted.'

Code Snippets (Illustrative - Not Executable)

Note: This is just a conceptual example to demonstrate the logic. Actual implementation would be more complex.

``` // Hypothetical code for checking permissions function checkPermission(user, data) { // Logic to determine if user has permission to access data // Example: Check if user has the 'employee' role return user.hasRole('employee'); }
