What is Shared Responsibility Model in Cybersecurity?
The shared responsibility model divides security obligations between the cloud provider and the customer. Cloud providers secure the underlying infrastructure (physical security, hypervisor, network), while customers secure their data, configurations, identity management, and application code. The exact division varies by service type: IaaS, PaaS, and SaaS each shift different responsibilities to the provider.
Why Shared Responsibility Model Matters for Your Cybersecurity Career
Misunderstanding the shared responsibility model is the root cause of many cloud security failures. Organizations assume the cloud provider handles security that is actually their responsibility. Every cybersecurity professional working with cloud services must understand where provider responsibility ends and customer responsibility begins.
