Policy Syntax

Last updated: 2022-02-09 16:16:21


    Access policies can be used to grant access to RUM. They use JSON-based access policy syntax. You can authorize specified principals to perform specified operations on specified RUM resources through the access policy syntax.

    The access policy syntax describes the basic elements and usage of the policy. For the description of the policy syntax, see Permission.

    Policy Syntax

    CAM policy:

                 "condition": {"key":{"value"}} 

    Element usage

    • version is required. Currently, only the value "2.0" is allowed.
    • statement describes the details of one or more permissions. It contains a permission or permission set of multiple other elements such as effect, action, resource, and condition. One policy has only one statement.
      1. effect describes whether the statement result is an "allow" or "explicit deny", which is required.
      2. action describes the allowed or denied action (operation). An operation can be an API (prefixed with "name") or a feature set (a set of specific APIs prefixed with "permid"). This element is required.
      3. resource describes the details of authorization. A resource is described in a six-segment format. Detailed resource definitions vary by product. For more information on how to specify resources, see the product documentation corresponding to the resource statement you are writing. This element is required.
      4. condition describes the condition for the policy to take effect. A condition consists of operator, action key, and action value. A condition value may contain information such as time and IP address. Some services allow you to specify additional values in a condition. This element is optional.

    Specifying effect

    If access to a resource is not explicitly granted (allowed), then it is implicitly denied. It can also be explicitly denied, which ensures that users cannot access the resource even if they are granted the access permission by other policies. Below is an example of specifying the "allow" effect:

    "effect" : "allow"

    Specifying action

    RUM defines console operations that can be specified in a policy. The specified operations are divided into reading part of APIs (apm:Describe*) and all APIs (apm:*) according to the operation nature.

    Below is an example of specifying the allowed operations:

    "action": [

    Specifying resource

    The resource element describes one or more operation objects, such as RUM resources. All resources can use the following six-segment format:


    The parameters are as detailed below:

    Parameter Description Required
    qcs Tencent Cloud service abbreviation, which indicates a service of Tencent Cloud Yes
    project_id Project information, which is only used to enable compatibility with legacy CAM logic and generally can be left empty No
    service_type Product abbreviation, which is rum here Yes
    region Region information Yes
    account Root account information of the resource owner, i.e., root account ID in the format of uin/${OwnerUin}, such as uin/100000000001 Yes
    resource Resource details prefixed with instance Yes

    Below is a sample six-segment description of a RUM resource:


    Use Cases

    Grant the read and write permissions of specified resources based on resource ID. The root account ID is 1250000000:

    Sample: granting the sub-user the permission to query the business system (ID: rum-vpasY123).

      "version": "2.0",
      "statement": [
              "effect": "allow",
              "action": [
              "resource": [
