Cloud Security Architecture
Public cloud environments require layered controls around identity, network topology, data protection, deployment governance, and continuous monitoring. Cloud security is designed to reduce risk from misconfiguration, credential abuse, lateral movement, and untrusted workloads.
What it is for
- Hosting workloads, data, and shared services in multi-account or multi-region landscapes
- Supporting developer delivery with secure landing zones and managed platform services
- Enforcing boundary controls between internet, app, data, and operations planes
- Meeting regulatory, audit, and resiliency requirements for business-critical systems
Design principles
- Least privilege IAM with role separation and just-in-time access
- Private-only connectivity with explicit ingress and egress rules
- Encryption everywhere for data at rest and in transit
- Centralized logging, security posture management, and alerts
