Cloud Security Principles
What Is Cloud Security?
Cloud security refers to the policies, controls, and technologies used to protect data, applications, and infrastructure hosted in cloud environments from threats and unauthorized access.
The Shared Responsibility Model
Cloud security operates on a shared responsibility model, where the cloud provider secures the underlying infrastructure, while the customer is responsible for securing their data, identities, applications, and configurations within the cloud.
Key Cloud Security Principles
| Principle | Description |
|---|---|
| Identity and Access Management | Controls who can access cloud resources and what they can do |
| Data Encryption | Protects data stored and transmitted within the cloud |
| Configuration Management | Prevents misconfigurations that expose resources publicly |
| Continuous Monitoring | Detects unusual activity across cloud resources |
Common Cloud Security Risks
Misconfigured storage buckets, weak identity controls, and lack of visibility across multi-cloud environments are among the most common causes of cloud security incidents.
Cloud security principles protect data and workloads hosted with a provider, but the underlying operating systems - Linux and Windows - still need to be secured directly.
