Objectives
- Understand the "Shared Responsibility Model" in a hybrid context.
- Identify hybrid-specific security risks and how to mitigate them.
- Learn about Zero Trust architecture and its application to hybrid cloud.
1. Shared Responsibility Model
Security is a partnership between you and the cloud provider.
- Cloud Provider Responsibility: Security OF the cloud (Physical data centers, core networking, hardware).
- Customer Responsibility: Security IN the cloud (Your data, application code, identity management, and the "bridge" connecting to on-premises).
2. Hybrid Security Risks
- Increased Attack Surface: More entry points (on-premises, cloud, and the connection between them).
- Misconfigurations: Inconsistent security policies between environments.
- Access Control: Complications in managing permissions across different systems.
- Insecure Connections: Risk of data interception if tunnels are not properly encrypted.
3. Mitigating Risks
- Zero Trust Architecture: Never trust, always verify. Every request (even from within the network) must be authenticated and authorized.
- Encryption Everywhere: Use encryption for data at rest (on-premises and in the cloud) and data in transit.
- Regular Audits: Use automated tools (e.g., Security Command Center) to scan for vulnerabilities and compliance violations.
Practical Exercise: Security Audit
- A user is able to access a database in the cloud from an unmanaged personal laptop at home. Which security principle has been violated?
- List 3 security measures you would implement to protect the connection between your data center and the cloud.
- Define the "Shared Responsibility" for a Managed Kubernetes service (like GKE or AKS) in a hybrid setup.
