云备份自定义权限策略参考_云备份(Cloud Backup)-阿里云帮助中心

如果系统权限策略不能满足您的要求，您可以创建自定义权限策略实现最小授权。使用自定义权限策略有助于实现权限的精细化管控，是提升资源访问安全的有效手段。本文介绍<云服务名称>使用自定义权限策略的场景和策略示例。

什么是自定义权限策略

在基于RAM的访问控制体系中，自定义权限策略是指在系统权限策略之外，您可以自主创建、更新和删除的权限策略。自定义权限策略的版本更新需由您来维护。

创建自定义权限策略后，需为RAM用户、用户组或RAM角色绑定权限策略，这些RAM身份才能获得权限策略中指定的访问权限。
已创建的权限策略支持删除，但删除前需确保该策略未被引用。如果该权限策略已被引用，您需要在该权限策略的引用记录中移除授权。
自定义权限策略支持版本控制，您可以按照RAM规定的版本管理机制来管理您创建的自定义权限策略版本。

常见自定义权限策略场景及示例

云备份提供备份恢复权限分离功能。给指定RAM用户添加RAM权限，使得该RAM用户对此备份库只能进行备份或者恢复操作，避免未经授权的误操作。

禁止恢复/取回的权限策略

单击脚本左上角复制按钮，快速复制脚本。例如：

{
    "Version": "1",
    "Statement": [
        {
            "Effect": "Deny",
            "Action": [
                "hbr:CreateRestore",
                "hbr:CreateRestoreJob",
                "hbr:CreateHanaRestore",
                "hbr:CreateUniRestorePlan",
                "hbr:CreateSqlServerRestore"
            ],
            "Resource": [
                "acs:hbr:*:1178037424989531:vault/v-0000ryfi******piu",
                "acs:hbr:*:1178037424989531:vault/v-0000ryfi******piu/client/*"
            ]
        }
    ]
}

说明

v-0000ryfi******piu为目标备份库ID。

禁止备份/归档的权限策略

单击脚本左上角复制按钮，快速复制脚本。例如：

{
    "Version": "1",
    "Statement": [
        {
            "Effect": "Deny",
            "Action": [
                "hbr:CreateUniBackupPlan",
                "hbr:UpdateUniBackupPlan",
                "hbr:DeleteUniBackupPlan",
                "hbr:CreateHanaInstance",
                "hbr:UpdateHanaInstance",
                "hbr:DeleteHanaInstance",
                "hbr:CreateHanaBackupPlan",
                "hbr:UpdateHanaBackupPlan",
                "hbr:DeleteHanaBackupPlan",
                "hbr:CreateClient",
                "hbr:CreateClients",
                "hbr:UpdateClient",
                "hbr:UpdateClientSettings",
                "hbr:UpdateClientAlertConfig",
                "hbr:DeleteClient",
                "hbr:DeleteClients",
                "hbr:CreateJob",
                "hbr:UpdateJob",
                "hbr:CreateBackupPlan",
                "hbr:UpdateBackupPlan",
                "hbr:ExecuteBackupPlan",
                "hbr:DeleteBackupPlan",
                "hbr:CreateBackupJob",
                "hbr:CreatePlan",
                "hbr:UpdatePlan",
                "hbr:CreateTrialBackupPlan",
                "hbr:ConvertToPostPaidInstance",
                "hbr:KeepAfterTrialExpiration"
            ],
            "Resource": [
                "acs:hbr:*:1178037424989531:vault/v-0000ryfi******piu",
                "acs:hbr:*:1178037424989531:vault/v-0000ryfi******piu/client/*"
            ]
        }
    ]
}

说明

v-0000ryfi******piu为目标备份库ID。

防止RAM用户误删备份数据的RAM Policy示例如下：

{
    "Version": "1",
    "Statement": [{
        "Effect": "Deny",
        "Action": [
            "hbr:DeleteBackupClient",
            "hbr:DeleteContact",
            "hbr:DeleteContactGroup",
            "hbr:DeleteVault",
            "hbr:DeleteJob",
            "hbr:DeleteClient",
            "hbr:DeleteHanaBackupPlan",
            "hbr:DeleteClients",
            "hbr:DeleteBackupSourceGroup",
            "hbr:DeleteBackupPlan",
            "hbr:DeleteHanaInstance",
            "hbr:DeleteSqlServerInstance",
            "hbr:DeleteSnapshot",
            "hbr:DeleteSqlServerSnapshot",
            "hbr:DeleteSqlServerLog",
            "hbr:DeleteVcenter",
            "hbr:DeleteUdmEcsInstance",
            "hbr:DeleteAppliance",
            "hbr:DeleteUniBackupClient",
            "hbr:DeleteUniBackupPlan",
            "hbr:DeleteUniBackupCluster",
            "hbr:DeleteUniRestorePlan"
        ],
        "Resource": [
            "acs:hbr:*:{uid}:vault/{vaultId}",
            "acs:hbr:*:{uid}:vault/{vaultId}/*"
        ]
    }]
}

说明

其中，vaultId表示需要保护的备份库ID，如果要保护所有仓库，请填写星号（*）。
