界: Encapsulation

封装即绘制强边界。在 Web 浏览器中，这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上，这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据，或者区分允许用户查看的数据和不允许用户查看的数据。

AWS CloudFormation Misconfiguration: Insecure SNS Topic Storage

JSON
YAML

Abstract

该模板定义了未加密的 SNS 主题。

Explanation

默认情况下，SNS 主题不会进行静态加密。这可能会将数据暴露给未经授权的查看者。

示例 1：以下示例模板由于没有定义 AWS KMS 密钥标识符而无法对 SNS 主题进行加密。


{
    "AWSTemplateFormatVersion": "2010-09-09",
    "Description": "My SNS topic",
    "Resources": {
        "MySNSTopic": {
            "Type": "AWS::SNS::Topic",
            "Properties": {
                "Subscription": [
                    {
                        "Endpoint": "MySNSEndpoint",
                        "Protocol": "sqs"
                    }
                ],
                "TopicName": "MyTopic"
            }
        }
    }
