Cloud security involves securing applications and data in cloud environments — understanding the shared responsibility model, securing identity and access, data, network, configuration, and avoiding cloud-specific misconfigurations (a leading cause of cloud breaches).
The shared responsibility model
The cloud provider secures the CLOUD (infrastructure, hardware, managed services);
YOU secure what's IN the cloud (your data, access config, app security, configurations):
→ know the BOUNDARY — what the provider handles vs what you must
→ MOST cloud breaches are CUSTOMER MISCONFIGURATIONS, not provider failures
→ understand your responsibilities (a common source of confusion and breaches).
