Role-Based Access Control (RBAC) Module Overview

The Role-Based Access Control (RBAC) module is a critical component of any authentication system designed to manage access rights within an organization or application. This module provides a structured and scalable way to define permissions and enforce security policies based on user roles, such as admin, student, instructor, or other custom-defined roles.

Purpose

The primary purpose of the RBAC module is to streamline access control by assigning permissions and privileges to users based on their roles within an organization or system. Instead of granting permissions individually to each user, RBAC allows developers to define roles and assign permissions to those roles. This approach ensures that users only receive the level of access necessary for their job functions, enhancing security and reducing the risk of unauthorized access.

RBAC is particularly useful in environments where multiple user types interact with a system, such as in educational platforms (students, instructors, admins), enterprise applications, or any system requiring fine-grained access control.

Benefits

Implementing RBAC offers several key benefits:

1. Simplified Permissions Management: Instead of managing permissions for each user individually, RBAC allows developers to define roles and assign permissions to those roles. This reduces complexity and administrative overhead.

2. Enhanced Security: By enforcing strict role-based access policies, RBAC minimizes the risk of unauthorized actions. Users are granted only the permissions necessary for their roles, reducing the attack surface.

3. Improved Auditing and Compliance: With RBAC, it is easier to track user activities and ensure compliance with organizational or regulatory requirements. Audit logs can be generated based on role-based access attempts.

4. Scalability: The RBAC module is designed to scale with the needs of your organization. New roles and permissions can be added as needed without disrupting existing configurations.

5. Fine-Grained Control: RBAC allows for precise control over user actions, such as restricting certain operations (e.g., deletion or editing) based on a user’s role.

Usage Scenarios

The RBAC module is applicable in various scenarios, including:

1. Multi-Tenant Applications: In platforms where multiple users interact with the system under different roles (e.g., admins managing tenant accounts, instructors teaching courses, students accessing course materials).

2. Enterprise Resource Planning (ERP): Restricting access to sensitive data or features based on user roles within an organization.

3. Educational Platforms: Managing access for different user types such as:

   • Admins: Full access to system settings, user management, and reporting tools.
   • Instructors: Access to course materials, grade books, and student records.
   • Students: Limited access to course content, assignments, and grades.

4. Healthcare Systems: Enforcing strict access control for patient data based on roles such as doctors, nurses, administrators, or patients themselves.

5. Content Management Systems (CMS): Allowing different roles (authors, editors, admins) to perform specific actions like creating, editing, publishing, or deleting content.

6. API Security: Securing APIs by enforcing RBAC policies to ensure only authorized users can access specific endpoints based on their roles.

Conclusion

The Role-Based Access Control module is a powerful tool for developers seeking to implement secure and scalable access control mechanisms in their applications. By leveraging predefined user roles and assigning permissions accordingly, this module simplifies permission management, enhances security, and ensures compliance with organizational policies. Whether managing an educational platform, enterprise application, or any other system requiring role-based access, the RBAC module provides a robust solution for developers to enforce fine-grained control over user access.

# Role-Based Access Control Module Documentation

This module implements **Role-Based Access Control (RBAC)** to manage permissions and access control within the system based on user roles.

## Features

### Role Hierarchy
- Define parent-child relationships between roles to inherit permissions. For example, a "Manager" role can have access rights inherited from an "Employee" role.

### Permission Scoping
- Assign specific permissions to roles for different resources or contexts (e.g., database tables, API endpoints, or file directories).
- Permissions can be scoped to individual records, such as allowing a student to view only their own records.

### Fine-Grained Permissions
- Define granular permissions at the action level (e.g., CRUD operations: Create, Read, Update, Delete) for specific resources.
- Example: Allow "instructors" to update course details but not delete them.

### Session Management
- Track active user sessions and enforce role-based access checks during each request.
- Implement session timeout and automatic logout after inactivity.

### Auditing and Logging
- Log all access attempts and changes in permissions for auditing purposes.
- Generate reports on unauthorized access attempts or permission violations.

### Integration with Identity Providers
- Integrate with third-party identity providers (e.g., LDAP, OAuth) to synchronize user roles and permissions.

### Multi-Tenant Support
- Manage multiple organizations or tenants within a single system by applying role-based policies per tenant.

### Dynamic Role Assignment
- Assign or revoke roles dynamically based on real-time conditions or events.
- Example: Automatically promote a user to "admin" during specific time periods.

### API Security
- Protect RESTful APIs and web services with RBAC checks to ensure only authorized users can access endpoints.

Role-Based Access Control Module Documentation

This documentation provides details about the Role-Based Access Control (RBAC) module, including its purpose, key concepts, and example implementations in different technologies.

Overview

The RBAC module allows you to define permissions and access control based on user roles. It enforces security policies where users are assigned specific roles (e.g., admin, student, instructor), and these roles determine what actions they can perform within the system.

Key Concepts

• User: An individual entity that interacts with the system.
• Role: A set of permissions assigned to a user, determining what actions they are allowed to take.
• Permission: Specific actions or resources a role can access (e.g., “view”, “edit”).
• Resource: The object or endpoint being accessed (e.g., “/api/users”).

API Reference

FastAPI Endpoint Example

The following example shows a FastAPI endpoint that demonstrates RBAC functionality:

from fastapi import FastAPI, Depends, HTTPException
from typing import List
from rbac.models import Role, Permission, User
from rbac.auth import requires_role

app = FastAPI()

@app.get("/users")
@requires_role("admin")
async def get_users() -> List[User]:
    return users_db  # Replace with your actual data source

React UI Example

Here’s a React component snippet that demonstrates role assignment:

import React, { useState } from 'react';

function RoleAssignment() {
  const [userRoles, setUserRoles] = useState({
    userId: 1,
    roles: ['admin', 'student']
  });

  const toggleRole = (role) => {
    setUserRoles(prev => ({
      ...prev,
      roles: prev.roles.includes(role)
        ? prev.roles.filter(r => r !== role)
        : [...prev.roles, role]
    }));
  };

  return (
    <div>
      <h2>Assign Roles to User {userRoles.userId}</h2>
      <ul>
        <li>
          <button onClick={() => toggleRole('admin')}>
            {userRoles.roles.includes('admin') ? 'Remove Admin' : 'Add Admin'}
          </button>
        </li>
        <li>
          <button onClick={() => toggleRole('student')}>
            {userRoles.roles.includes('student') ? 'Remove Student' : 'Add Student'}
          </button>
        </li>
      </ul>
    </div>
  );
}

export default RoleAssignment;

Data Schema Example (Pydantic)

The following Pydantic models define the data schema for RBAC:

from pydantic import BaseModel

class Permission(BaseModel):
    action: str
    resource: str

class Role(BaseModel):
    name: str
    permissions: List[Permission]

class User(BaseModel):
    id: int
    username: str
    roles: List[str]
