🔐 Module 2: Identity, Security & Compliance (Intermediate)

Welcome to the world of security! 🌍 Now that we know how to build things in Azure, we need to learn how to protect them. In this module, we will learn about identities (who you are), security (keeping bad guys out), and compliance (following the rules). Think of it like a castle – you build walls, guard towers, and only let trusted people inside.

🎯 Learning Objectives

• Understand Microsoft Entra ID (Azure AD) and how it manages users.
• Learn about Single Sign-On (SSO) and Multi-Factor Authentication (MFA).
• Use Role-Based Access Control (RBAC) to give the right permissions.
• Secure your resources with Azure Security Center and Azure Defender.
• Protect secrets with Azure Key Vault.
• Enforce rules with Azure Policy and Azure Blueprints.

📖 Warm-up Story: The Secure Castle

Imagine you are the king or queen of a big castle 🏰. Inside the castle, you have treasure, important documents, and many rooms.

You need to make sure that:

• Only the right people can enter the castle (Identity).
• Guards check IDs at the gate (Authentication).
• Some rooms are off-limits to most people (RBAC).
• You have security cameras to watch everything (Azure Security Center).
• You have rules that everyone must follow (Azure Policy).

In this module, you will learn how to build your own secure castle in Azure!

📘 Main Lessons

1. Microsoft Entra ID – The Identity Service

Definition: Microsoft Entra ID (formerly Azure AD) is a cloud-based service that manages users and their access to resources.

Why important: It is the central place where you control who can access your Azure resources.

Simple: Like a school register – it has the names of all students and who can enter which classroom.

Real-life: A company uses Entra ID to manage employee logins to all their apps.

School: The school uses a system to manage student and teacher logins.

Home: Your Microsoft account is an Entra ID identity.

Nigerian: A Lagos bank uses Entra ID to manage employee access to banking apps.

    Entra ID = Master list of users and their permissions
    ├── Users (people)
    ├── Groups (teams)
    └── Applications (apps they can use)
    

✅ Summary: Entra ID is the service that manages identities in Azure.

---

2. Tenants – Your own space in Azure

Definition: A tenant is a dedicated instance of Entra ID for your organisation. It is like your own private copy of the service.

Why important: It keeps your users and data separate from other organisations.

Simple: Like having your own locker at school – only you have the key.

Real-life: Each company has its own tenant.

School: The school has its own tenant for all teachers and students.

Home: Not used at home.

Nigerian: A fintech has its own tenant for its employees.

    Tenant = Your private directory in Entra ID

---

3. Users and Groups – Who are you?

Definition: A user is a person (or application) that needs access. A group is a collection of users.

Why important: Groups make it easy to give permissions to many people at once.

Simple: A user is like a student; a group is like a class.

Real-life: A company has users (employees) and groups (Marketing, Sales, IT).

School: Students are users; a class is a group.

Home: Family members are users; the "family" is a group.

Nigerian: A startup has users (employees) and groups (Developers, Managers).

    User = Individual person
    Group = Collection of users (e.g., "Finance Team")
    

✅ Summary: Users are individuals; groups are collections of users.

---

4. Single Sign-On (SSO) – One login for everything

---

6. Role-Based Access Control (RBAC) – Who can do what?

Definition: RBAC assigns permissions to users, groups, or applications based on their roles.

Why important: You give people only the permissions they need.

Simple: Like a school where teachers can grade, but students can only view.

Real-life: An admin can create VMs, a reader can only view them.

School: The principal can change settings, but the librarian can only view.

Home: Parents have full control, children have limited access.

Nigerian: A company gives developers "contributor" rights but not "owner".

Role	Permissions
Owner	Can do everything

    ├── Secrets (passwords, keys)
    ├── Keys (encryption keys)
    └── Certificates (SSL/TLS)
    

✅ Summary: Key Vault securely stores your secrets.

---

10. Managed Identities – Automatic identity for Azure services

Definition: A managed identity is an identity that Azure creates for a service (like a VM or Function) so it can authenticate to other Azure services.

Why important: You don't need to store credentials – Azure handles it.

Simple: Like a security badge that is automatically given to a robot.

Real-life: A VM uses a managed identity to access Key Vault.

---

11. Azure Policy – Enforce rules

Definition: Azure Policy is a service that lets you create rules to enforce standards across your resources.

Why important: It prevents people from making mistakes, like creating VMs in the wrong region.

Simple: Like school rules – you can't run in the hallway.

Real-life: A company uses a policy to only allow VMs in a specific region.

School: A policy ensures all school resources use the same naming convention.

Home: Not used at home.

Nigerian: A bank uses policies to ensure all VMs are in South Africa.

    Policy: Allowed locations = South Africa, Europe
    If VM created in US → Policy denies it
    

✅ Summary: Azure Policy enforces rules to keep things consistent.

---

12. Azure Blueprints – Create compliant environments

Definition: Azure Blueprints is a service that lets you define a set of resources, policies, and roles to create a repeatable environment.

    - CanNotDelete (prevents deletion)
    - ReadOnly (prevents changes)
    

✅ Summary: Resource locks protect important resources from being deleted or changed.

---

14. Tags – Labels for organisation

Definition: Tags are key-value pairs (like "Project: Website" or "CostCenter: Marketing") that you add to resources.

Why important: They help you organise, track costs, and manage resources.

Simple: Like putting sticky notes on your belongings to know what they are for.

Real-life: A company tags resources by project, department, and environment (Dev/Prod).

School: Tags can show which class uses which resource.

Home: You might tag photos with names and dates.

Nigerian: A startup tags resources by region (Lagos, Abuja).

    Tag: Environment = Production
    Tag: Department = Finance
    Tag: Project = PayrollApp
    

✅ Summary: Tags are labels that help you organise and track resources.

---

15. Defense in Depth – Multi-layered security

Definition: Defense in depth is a strategy that uses multiple layers of security to protect your resources. If one layer fails, another layer stops the attack.

Why important: It's like having multiple doors – if a thief breaks one, there is still another locked door.

Simple: Like a castle with walls, a moat, and guards.

Real-life: A company uses network firewalls, MFA, and encryption.

School: The school has locks on doors, security cameras, and passwords.
