Foundational Security Principles
Shared Responsibility Model
Understanding the division of security responsibilities between cloud providers and customers:
- Provider Responsibilities: Physical security, infrastructure, and platform services
- Customer Responsibilities: Data protection, identity management, and application security
- Shared Areas: Network controls, operating system patches, and firewall configuration
Defense in Depth Strategy
Implementing multiple layers of security controls:
- Perimeter Security: Web application firewalls and DDoS protection
- Network Security: Virtual private clouds and network segmentation
- Compute Security: Instance hardening and runtime protection
- Data Security: Encryption at rest and in transit
- Application Security: Secure coding and vulnerability management
