Module 3: Azure Security 🔵
Learn Microsoft Azure security implementation and monitoring.
Learning Objectives
- • Understand Azure security architecture and services
- • Master Azure Active Directory and identity management
- • Configure network security and monitoring
- • Implement Azure security best practices
Azure Security Architecture
Azure provides a comprehensive security framework with multiple layers of protection.
Security Layers
- • Physical Security: Data center protection
- • Infrastructure Security: Network and compute security
- • Application Security: Code and configuration security
- • Data Security: Encryption and access controls
- • Identity Security: Authentication and authorization
Security Services
- • Azure Security Center: Unified security management
- • Azure Sentinel: SIEM and SOAR platform
- • Azure Key Vault: Secrets and key management
- • Azure Information Protection: Data classification
- • Azure DDoS Protection: DDoS mitigation
Azure Active Directory (Azure AD)
Identity Management
- • User Management: Create and manage user accounts
- • Group Management: Organize users into groups
- • Role-based Access Control: Assign permissions
- • Conditional Access: Dynamic access policies
- • Multi-factor Authentication: Enhanced security
Authentication Methods
- • Password Authentication: Traditional username/password
- • Windows Hello: Biometric authentication
- • Certificate-based: Smart card authentication
- • OAuth 2.0/OpenID Connect: Modern protocols
- • SAML: Single sign-on integration
Network Security
Azure provides comprehensive network security controls for protecting resources.
Network Security Components
- • Network Security Groups: Firewall rules for subnets
- • Application Security Groups: Logical grouping of VMs
- • Azure Firewall: Cloud-native network security
- • Virtual Networks: Network isolation and segmentation
- • Private Endpoints: Private service connections
Network Design Best Practices
- • Hub-Spoke Architecture: Centralized network management
- • Subnet Segmentation: Separate subnets by purpose
- • Network Security Groups: Layer 4 filtering
- • Azure Firewall: Layer 7 filtering
- • ExpressRoute: Private network connections
Azure Sentinel
Azure Sentinel is a cloud-native SIEM and SOAR solution for security operations.
SIEM Capabilities
- • Data Collection: Log ingestion from multiple sources
- • Threat Detection: AI-powered threat detection
- • Incident Management: Case management and investigation
- • Hunting: Proactive threat hunting
- • Dashboards: Security visualization
SOAR Features
- • Playbooks: Automated response workflows
- • Connectors: Third-party integrations
- • Custom Analytics: KQL query language
- • Machine Learning: Advanced analytics
- • Community Content: Shared security content
Data Protection
Azure provides comprehensive data protection capabilities for securing sensitive information.
Encryption Services
- • Azure Key Vault: Centralized key management
- • Customer-managed Keys: User-controlled encryption
- • Azure Disk Encryption: VM disk encryption
- • Storage Service Encryption: Storage account encryption
- • Transparent Data Encryption: Database encryption
Data Governance
- • Azure Information Protection: Data classification
- • Data Loss Prevention: Sensitive data protection
- • Retention Policies: Data lifecycle management
- • Access Reviews: Regular permission audits
- • Privileged Identity Management: Just-in-time access
