云安全涉及保护云环境中的应用程序和数据——理解共享责任模型、保护身份和访问、数据、网络、配置,以及避免云特定的配置错误(导致大多数云泄露的主要原因)。
共享责任模型
text
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).
