Azure Security Tutorial

Overview

Welcome to the Azure Security tutorial. This guide walks you through the core security capabilities of Microsoft Azure, from identity management to data protection, network hardening, and compliance monitoring.

Identity & Access Management

Azure Active Directory (AAD)

Azure AD provides centralized identity management, single sign‑on, and multi‑factor authentication (MFA). Learn to configure conditional access policies, role‑based access control (RBAC), and identity protection.

Managed Identities

Managed identities eliminate credential storage by providing Azure services with an automatically managed identity in Azure AD.

Privileged Identity Management (PIM)

PIM helps you manage, control, and monitor privileged access to Azure resources. It enables just‑in‑time (JIT) role activation and access reviews.

Network Security

Network Security Groups (NSG)

NSGs filter inbound and outbound traffic to Azure resources. Use security rules to allow or deny traffic based on source, destination, port, and protocol.

Azure Firewall

Azure Firewall is a managed, stateful firewall-as-a-service that provides network‑level protection, threat intelligence filtering, and logging.

Azure DDoS Protection

Built‑in DDoS mitigation automatically protects your resources from large‑scale attacks.

Data Protection

Encryption at Rest

Azure uses Service‑Managed Keys (default) or Customer‑Managed Keys (CMK) with Azure Key Vault for encryption of storage accounts, disks, and databases.

Encryption in Transit

TLS/SSL is enforced for data moving between services and users. Azure Front Door and Application Gateway can enforce HTTPS only.

Azure Confidential Computing

Protect data while in use with hardware‑based secure enclaves, ensuring code and data remain confidential even from the cloud provider.

Monitoring & Compliance

Azure Security Center (Defender)

Provides unified security management and advanced threat protection across hybrid cloud workloads.

Azure Monitor & Log Analytics

Collect, analyze, and act on telemetry data. Set alerts for suspicious activity and integrate with Azure Sentinel.

Compliance Manager

Tracks compliance with standards such as ISO 27001, GDPR, and NIST, providing actionable insights.

Best Practices

  • Enable MFA for all privileged accounts.
  • Use least‑privilege RBAC and regular access reviews.
  • Deploy NSGs and Azure Firewall together for layered defense.
  • Encrypt data at rest and in transit; consider CMK for sensitive workloads.
  • Continuously monitor with Security Center and set automated alerts.
