示例：AppStream 2.0 实例集机器角色跨服务混淆代理问题预防

例 aws:SourceAccount 条件：
JSON
{
    "Version":"2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "appstream.amazonaws.com"
                ]
            },
            "Action": "sts:AssumeRole",
            "Condition": {
                "StringEquals": {
                    "aws:SourceAccount": "your AWS 账户 ID"
                }
            }
        }
    ]
}
例 aws:SourceArn 条件：
注意

如果要将一个 IAM 角色用于多个实例集，我们建议使用带通配符（*）的 aws:SourceArn 全局条件上下文键来匹配多个 AppStream 2.0 实例集资源。
