In this recipe, we’ll create access control policies in Startree ThirdEye. Here we restrict access by region, however access control policies can be used to restrict access of any data dimension to any set of Okta groups or other user attributes. For a more in-depth explanation of how access control and authorization works in ThirdEye, see Access Control in Thirdeye. We’ll create an alert with regional data in the US and Canada, and restrict access to the alert data to 3 categories of users:
  • Regional analysts
    • Assigned to Okta group regional_analysts_us or regional_analysts_ca.
    • View alerts for their region.
    • Manage anomalies and investigations for their region.
  • Global Viewers
    • Assigned to Okta group global_viewers.
    • View alerts, anomalies, and investigations for any region.
  • Admins/makers:
    • Assigned to Okta group thirdeye_admin.
    • Create alerts for any region.
    • Manage authorization policies.

​
Recipe outline

  1. Handle prerequisites and setup
  2. Create the namespaces we’ll use to group our ThirdEye resources
  3. Restrict access to ThirdEye resources with access control policies
  4. Create an alert with separate timeseries for US and Canada data using dimension exploration

​
Prerequisites

  1. Obtain your StarTree cloud bearer token.
  2. Log into the Authorization server’s UI. If your ThirdEye is at https://thirdeye.my-env.my-org.startree.cloud, then the authorization server ui is at https://my-env.my-org.startree.cloud/auth/swagger-ui/index.html.
The alert will use data from the pageviews demo dataset and dimension exploration to segment the data into different regions.

​
Namespaces

First, we’ll create a set of namespaces to group our ThirdEye alerts, anomalies and other resources. The access control policies will apply to these namespaces instead of individual resources. Namespaces are string values that must match regex ^[a-z0-9-_]+$. We set the namespace of alerts and its enumeration items in the alert configuration. Anomalies and investigations are automatically assigned to the namespace of the alert or enumeration item it is assigned to. Resources that do not have a configured namespace are placed in the default namespace. In this recipe, we’ll create 3 namespaces:
  • thirdeye_dx_alerts - This will contain the dimension exploration alerts.
  • regional_analysts_us - This will contain the US dimension and all related investigations and anomalies.
  • regional_analysts_ca - This will contain the CA dimension and all related investigations and anomalies.
All other ThirdEye resources like alert templates, datasets, and data sources will go into the default namespace. ThirdEye resources placed in labeled containers. The individual namespace permissions are broken down in this table: ThirdEye Namespace Permissions

​
Create the namespaces

Here are the JSON payloads needed to create the namespaces. To enable each, copy and paste the code directly into the Swagger UI’s create namespace tool.
If you get a 403 Forbidden error, this means you do not have permission to create namespaces. Reach out to ThirdEye support for help.

​
thirdeye_dx_alerts

{
  "name": "thirdeye_dx_alerts",
  "description": "ThirdEye dimension exploration alerts.",
  "enabled": true
}

​
regional_analysts_us

{
  "name": "regional_analysts_us",
  "description": "Anomalies and investigation for US.",
  "enabled": true
}

​
regional_analysts_ca

{
  "name": "regional_analysts_ca",
  "description": "Anomalies and investigation for Canada.",
  "enabled": true
}

​
Policies

Next, let’s create the policies. Like ThirdEye resources, policies are assigned to a namespace. A policy will only apply to resources in its namespace, except for one special case: Policies in the default namespace are applied to all resources.

​
Create the policies

To enable each, copy and paste the code directly into the Swagger UI’s create policy tool.

​
Grant read and write access to the admin group

This policy allows users in the thirdeye_admin Okta group to read and write all entities. We assign the policy to the default namespace, so all entities are covered. 
{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:default:default",
  "priority": 1,
  "rule": "subject_user_groups CONTAINS 'thirdeye_admin'",
  "description": "Allow users in the thirdeye_admin Okta group to read and write all entities."
}

​
Grant read access to global viewers

This policy allows users in the global_viewers Okta group to read all entities. Same as before, this policy goes in the default namespace to cover all entities. 
{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:default:default",
  "priority": 2,
  "rule": "subject_user_groups CONTAINS 'global_viewers' AND action='read'",
  "description": "Allow users in the global_viewers Okta group to read all entities."
}

​
Grant read access for all alert templates

This policy allows all users to read the alert templates. Since alert templates are used to render alerts, but cannot be used to view data by themselves, we can use a lenient read policy. This policy will cover the standard ThirdEye alert templates, which are in the default namespace. 
{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:default:default",
  "priority": 3,
  "rule": "resource_srn_entity='thirdeye-alert_template' AND action='read'",
  "description": "Allow all users to read ThirdEye alert templates."
}

​
Grant read access for the dimension exploration alerts

This policy allows all users to read the ThirdEye alerts in the thirdeye_dx_alerts namespace. When we create an alert, we must also assign it to the thirdeye_dx_alerts namespace so all users can see it. 
{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:thirdeye_dx_alerts:default",
  "priority": 4,
  "rule": "action='read'",
  "description": "Allow all users to read all entities in the thirdeye_dx_alerts namespace."
}

​
Grant read+write access to anomalies and investigations in the regional namespaces.

Finally, let’s create policies to allow our regional analysts to read and write anomalies and investigations in their namespaces. 
{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:regional_analysts_us:default",
  "priority": 1010,
  "rule": "subject_user_groups CONTAINS 'regional_analysts_us' AND (resource_srn_entity='thirdeye-anomaly' OR resource_srn_entity='thirdeye-rca_investigation')",
  "description": "Allow users in the regional_analysts_us okta group to read and write anomalies and investigations in the regional_analysts_us namespace."
}

{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:regional_analysts_ca:default",
  "priority": 1110,
  "rule": "subject_user_groups CONTAINS 'regional_analysts_ca' AND (resource_srn_entity='thirdeye-anomaly' OR resource_srn_entity='thirdeye-rca_investigation')"
  "description": "Allow users in the regional_analysts_ca okta group to read and write anomalies and investigations in the regional_analysts_ca namespace."
}

​
(Optional) Grant read access to all entities in the regional namespaces

We may want to create alerts without dimension exploration, but still have the anomalies and investigations stay in a regional namespace. For this use-case, we create the alert in the regional namespace instead of the thirdeye-dx-alerts namespace. We’ll then add a policy to allow our regional analysts read access to all entities in their namespace. 
{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:regional_analysts_ca:default",
  "priority": 1100,
  "rule": "subject_user_groups CONTAINS 'regional_analysts_ca' AND action='read'",
  "description": "Allow ca viewers read access to us resources."
}

{
  "policyType": "ALLOW",
  "namespaceSrn": "srn:zone:namespace:regional_analysts_us:default",
  "priority": 1000,
  "rule": "subject_user_groups CONTAINS 'regional_analysts_us' AND action='read'",
  "description": "Allow us viewers read access to us resources."
}

​
Create the Alert and Enumeration Items

Finally, it’s time to create the alert. This alert uses the startree-threshold-dx template and the pageviews demo dataset. The alert has two enumeration items: one for data from the US and one for data from Canada. The alert itself is created in the thirdeye_dx_alerts namespace that anyone can read, and the enumeration items are created in their region-specific namespace. Check that the dataSource and dataset template properties match the names for your instances. Paste this alert body in ThirdEye’s Create Alert JSON editor: 
{
  "name": "Views-Threshold-Dx-Recipe-Demo",
  "auth": {
    "namespace": "thirdeye_dx_alerts"
  },
  "template": {
    "name": "startree-threshold-dx"
  },
  "cron": "0 0 5 ? * MON-FRI *",
  "templateProperties": {
    "dataSource": "pinot",
    "dataset": "pageviews",
    "aggregationFunction": "SUM",
    "seasonalityPeriod": "P7D",
    "lookback": "P90D",
    "monitoringGranularity": "P1D",
    "sensitivity": "3",
    "aggregationColumn": "views",
    "queryFilters": "${queryFilters}",
    "max": "${max}",
    "min": "${min}",
    "enumerationItems": [
      {
        "name": "country='US'",
        "params": {
          "queryFilters": "AND country='US'",
          "max": "900000",
          "min": "120000"
        },
        "auth": {
          "namespace": "regional_analysts_us"
        }
      },
      {
        "name": "country='CA'",
        "params": {
          "queryFilters": "AND country='CA'",
          "max": "900000",
          "min": "10000"
        },
        "auth": {
          "namespace": "regional_analysts_ca"
        }
      }
    ]
  }
}

​
Results

With the access control policies in place, the alert will look different for the different user groups.

​
ThirdEye admins and global viewers

This is how the alert will look for the thirdeye admins and global viewers. We can see the timeseries and anomalies for both US and Canada. Alert seen by the thirdeye admin.

​
Regional analysts for US

This is how the alert will look for the US analysts. Only the timeseries and anomalies for the US are visible. Alert seen by the regional analyst in US.

​
Regional analysts for Canada

This is how the alert will look for the Canada analysts. Only the timeseries and anomalies for Canada are visible. Alert seen by the regional analyst in Canada.
