AWS CloudFormation Misconfiguration: FinSpace Missing Customer-Managed Encryption Key

Abstract

配置没有为静态数据指定任何客户管理的加密密钥。

Explanation

客户管理的密钥不用于加密静态数据。

默认情况下，如果启用了加密，AWS 会使用 AWS 管理的密钥来加密静态数据。客户管理的密钥允许组织使用他们选择的加密密钥来加密数据。这使组织可以更好地控制和记录加密过程。

因此，客户管理的密钥通常是满足以下要求的解决方案的一部分，包括但不限于：
- 敏感数据访问的审核日志
- 数据驻留
- 更换、禁用或销毁密钥

请注意，格式为 aws/service-name 的密钥是为 AWS 管理的密钥保留的。
