Here’s a structured summary of the lesson on Azure Key Vault for learning or exam preparation:Overview
  • Azure Key Vault is a managed service for securely storing and managing:
    • Cryptographic keys
    • Secrets (passwords, tokens)
    • X.509 certificates
  • Helps eliminate hard-coded credentials and protects high-value keys in FIPS 140-2 Level 2 HSMs.
1. Azure Disk Encryption (ADE)
  • Integrates Key Vault with:
    • BitLocker (Windows)
    • DM-Crypt (Linux)
  • Enables volume-level encryption for virtual machines.
  • Key points:
    • Check OS versions and minimum memory requirements.
    • Encryption is done using PowerShell walkthroughs.
2. Access Control and Policies
  • Two planes of management:
    1. Management Plane: Uses Azure RBAC to control vault administration.
    2. Data Plane: Uses Key Vault Access Policies to control access to keys, secrets, and certificates.
  • Allows granular permissions for:
    • Security teams
    • Developers
    • Applications
3. Network Security
  • Key Vault Firewall enables:
    • Denying public internet access
    • Restricting traffic to VNet service endpoints or authorized IP addresses
4. Monitoring and Auditing
  • Use diagnostic settings to log:
    • Audit events
    • Metrics
  • Analyze with:
    • Log Analytics
    • Azure Monitor Insights
  • Tracks:
    • Caller IP addresses
    • Failed operations
    • Latency
5. Certificate Management
  • Supports:
    • Provisioning self-signed certificates
    • Automated renewal via partner certificate authorities
    • Email alerts for certificate expiration
  • Important note: certificate access is a data plane operation, not management plane
AZ-500 Exam Focus
  • Skill area: Secure data and applications
  • Common exam points:
    • Understanding management vs data plane operations
    • Configuring network restrictions and access policies
    • Integrating Key Vault with ADE for VM encryption
    • Monitoring Key Vault operations for compliance
This lesson reinforces secure key and secret management, network restrictions, audit monitoring, and certificate lifecycle management—all crucial for both cloud security best practices and the AZ-500 exam.
