Azure 默认 Reader 与内置监控 Reader

Question

我正在尝试设置从安全角度监控数据的最佳角色。我的需求略有不同，所以我不想使用 Security Reader 角色（主要是因为 security reader 只能访问安全中心项目和基本资源和资源组查询）。因此，在阅读更多内容后，我偶然发现了 Monitoring Reader 角色和 Reader 角色。我通过了 JSON 中提到的权限。但是我不确定 JSON.

中是否涵盖了所有差异

例如，当我们谈论“监控 Reader”时

{
  "assignableScopes": [
    "/"
  ],
  "description": "Can read all monitoring data.",
  "id": "/subscriptions/{subscriptionId}/providers/Microsoft.Authorization/roleDefinitions/43d0d8ad-25c7-4714-9337-8ba259a9fe05",
  "name": "43d0d8ad-25c7-4714-9337-8ba259a9fe05",
  "permissions": [
    {
      "actions": [
        "*/read",
        "Microsoft.OperationalInsights/workspaces/search/action",
        "Microsoft.Support/*"
      ],
      "notActions": [],
      "dataActions": [],
      "notDataActions": []
    }
  ],
  "roleName": "Monitoring Reader",
  "roleType": "BuiltInRole",
  "type": "Microsoft.Authorization/roleDefinitions"
}

权限基本一样，就是可以查询日志。与 Reader 角色相比

{
  "assignableScopes": [
    "/"
  ],
  "description": "Lets you view everything, but not make any changes.",
  "id": "/subscriptions/{subscriptionId}/providers/Microsoft.Authorization/roleDefinitions/acdd72a7-3385-48ef-bd42-f606fba81ae7",
  "name": "acdd72a7-3385-48ef-bd42-f606fba81ae7",
  "permissions": [
    {
      "actions": [
        "*/read"
      ],
      "notActions": [],
      "dataActions": [],
      "notDataActions": []
    }
  ],
  "roleName": "Reader",
  "roleType": "BuiltInRole",
  "type": "Microsoft.Authorization/roleDefinitions"
}

现在从逻辑的角度来看，如果两个用户都能够执行 */read，Reader 角色是否自动有资格查询日志？如果不是，那有什么不同？还有哪个角色在访问可读数据方面更胜一筹？

参考：https://docs.microsoft.com/en-us/azure/role-based-access-control/built-in-roles#reader

PS : 我知道自定义角色，但想更好地了解内置角色。

Answer 1

Now from a logical standpoint if both the users are able to execute */read doesn't Reader role automatically qualify to query the logs?

他们都可以执行*/read，但是Reader不能查询日志。

If not, how is it different?

区别是Monitoring Reader可以执行Microsoft.OperationalInsights/workspaces/search/action和Microsoft.Support/*动作。

Also which role is superior in terms of access to readable data?

从角色定义的 actions 范围来看，显然 Monitoring Reader 在访问可读数据方面更胜一筹。
