Shared Security Responsibility
In cloud computing, security is a shared responsibility between the cloud provider and the customer. This model ensures that both parties are accountable for maintaining the security and integrity of the cloud environment.
Cloud Provider Security Responsibilities
Here's a breakdown of each cloud provider's security responsibilities:
| Cloud Provider | Security Responsibilities |
|---|---|
| AWS | Security "of" the cloud (infrastructure, network, hardware) |
| Azure | Security of infrastructure, network, hardware (varies by service type) |
| Google Cloud | Security of infrastructure, network, hardware (shared fate model) |
Customer Security Responsibilities
Customers are responsible for securing their applications, data, and identities in the cloud. This includes:
- Configuring IAM permissions
- Encrypting data
- Implementing network security controls
Understanding Shared Responsibility
Understanding the shared responsibility model is critical to ensuring the security and integrity of the cloud environment. By knowing their roles and responsibilities, businesses can effectively manage their cloud security and ensure compliance with regulatory requirements.
