Introduction to Azure Role-Based Access Control (RBAC)

1. What Is Azure RBAC?

Role-Based Access Control (RBAC) is Azure’s built-in authorization system that allows organizations to manage access to resources securely and efficiently. Instead of granting broad permissions, RBAC ensures least privilege, meaning users get only the access they need to perform their tasks.

RBAC is essential for:

• Securing cloud environments

• Delegating responsibilities safely

• Preventing accidental or malicious changes

2. Key RBAC Concepts

🔐 Role

A role defines a set of allowed actions. Common built-in roles include:

• Reader – View resources only

• Contributor – Create and manage resources (no access control)

• Owner – Full access, including role assignments

👤 Assignment

A role assignment connects a role to a user, group, managed identity, or service principal.

🎯 Scope

The scope determines where the role applies:

• Management Group

• Subscription

• Resource Group

• Individual Resource

Permissions inherit downward, making scopes a powerful access-control mechanism.

3. Step-by-Step: Create Your First Role Assignment

✅ Step 1: Log in to Azure Portal

Go to:
👉 https://portal.azure.com

✅ Step 2: Navigate to Access Control (IAM)

1. Open a Resource Group (e.g., MyRG)

2. Select Access control (IAM) from the left menu

✅ Step 3: Add Role Assignment

1. Click + Add → Add role assignment

2. Select Role: Reader

3. Assign access to: User

4. Select user: developer1@rshnetwork.com

5. Scope: Resource group – MyRG

6. Click Save

✔️ The user now has read-only access to the resource group.

4. Best Practices for Azure RBAC

✅ Follow the least privilege principle
✅ Assign roles at the lowest possible scope
✅ Use Azure AD groups instead of individual users
✅ Review role assignments regularly
✅ Avoid using Owner role unless absolutely necessary
