Review and apply role recommendations

This page explains how to view, understand, and apply role recommendations. Role recommendations help you enforce the principle of least privilege by ensuring that principals have only the permissions that they actually need.

Before you begin

Required IAM roles

This section describes the IAM roles and permissions that you need in order to work with role recommendations.

View recommendations

To get the permissions that you need to view role recommendations, ask your administrator to grant you the following IAM roles on the resource that you want to view recommendations for (project, folder, or organization):

  • Role Viewer (roles/iam.roleViewer)
  • IAM Recommender Viewer (roles/recommender.iamViewer)
  • To view project-level recommendations: Project IAM Admin (roles/resourcemanager.projectIamAdmin)
  • To view folder-level recommendations: Folder IAM Admin (roles/resourcemanager.folderIamAdmin)
  • To view organization-level recommendations: Organization Admin (roles/resourcemanager.organizationAdmin)

For more information about granting roles, see Manage access.

These predefined roles contain the permissions required to view role recommendations. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

  • iam.roles.get
  • iam.roles.list
  • recommender.iamPolicyRecommendations.get
  • recommender.iamPolicyRecommendations.list
  • recommender.iamPolicyInsights.get
  • recommender.iamPolicyInsights.list
  • recommender.iamPolicyLateralMovementInsights.get
  • recommender.iamPolicyLateralMovementInsights.list
  • resourcemanager.RESOURCE.getIamPolicy, where RESOURCE is the resource type that you want to view recommendations for (projects, folders, or organizations)

You might also be able to get these permissions with custom roles or other predefined roles.

Apply and dismiss recommendations

To get the permissions that you need to view, apply, and dismiss role recommendations, ask your administrator to grant you the following IAM roles on the resource that you want to manage recommendations for (project, folder, or organization):

  • Role Viewer (roles/iam.roleViewer)
  • IAM Recommender Admin (roles/recommender.iamAdmin)
  • To manage project-level recommendations: Project IAM Admin (roles/resourcemanager.projectIamAdmin)
  • To manage folder-level recommendations: Folder IAM Admin (roles/resourcemanager.folderIamAdmin)
  • To manage organization-level recommendations: Organization Admin (roles/resourcemanager.organizationAdmin)

For more information about granting roles, see Manage access.

These predefined roles contain the permissions required to view, apply, and dismiss role recommendations. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

  • iam.roles.get
  • iam.roles.list
  • recommender.iamPolicyRecommendations.get
  • recommender.iamPolicyRecommendations.list
  • recommender.iamPolicyInsights.get
  • recommender.iamPolicyInsights.list
  • recommender.iamPolicyLateralMovementInsights.get
  • recommender.iamPolicyLateralMovementInsights.list
  • recommender.iamPolicyRecommendations.update
  • resourcemanager.RESOURCE.getIamPolicy, where RESOURCE is the resource type that you want to manage recommendations for (projects, folders, or organizations)
  • resourcemanager.RESOURCE.setIamPolicy, where RESOURCE is the resource type that you want to manage recommendations for (projects, folders, or organizations)

You might also be able to get these permissions with custom roles or other predefined roles.

Review and apply recommendations

The easiest way to review and apply your recommendations is to use the Google Cloud console. Additionally, if you want to automatically create a custom role when you apply a recommendation, you must use the Google Cloud console.

You can also review and apply recommendations with the Google Cloud CLI and the Recommender API.

Console

  1. In the Google Cloud console, go to the IAM page.

    Go to IAM

  2. Select a project, folder, or organization.

  3. In the list of principals that have access to your project, find the Analyzed permissions column.

    For each role granted to a principal, this column shows any security-related insights. These insights highlight patterns in how your principals access resources. For example, some insights highlight excess permissions, or permissions that a principal does not need. Other insights highlight service accounts with lateral movement capabilities:

    If there is a recommendation available to address an insight, the Google Cloud console displays the Recommendation available icon.

  4. If there are recommendations to review, click a Recommendation available icon to get details about the recommendation.

    If the recommendation is to replace the role, the role recommendation always suggests a set of predefined roles that you can apply.

    In some cases, the role recommendation also suggests creating a new custom role at the project level. If a custom role recommendation is available, the Google Cloud console shows it by default. To switch to the predefined role recommendation, click View recommended predefined role.

  5. Review the recommendation carefully, and make sure you understand how it will change the principal's access to Google Cloud resources. Except in the case of recommendations for Google-managed service accounts, a recommendation will never increase a principal's level of access. See How role recommendations are generated for more information.

    To learn how to review recommendations in the console, see Review recommendations on this page.

  6. Optional: If the recommendation is to create a custom role, update the Title, Description, ID, and Role launch stage as needed.

    If you need to add permissions to the custom role, click Add permissions.

    If you need to remove permissions from the custom role, clear the checkbox for each permission that you want to remove.

  7. Take action on the recommendation.

    To apply the recommendation, click Apply or Create and apply. If you change your mind in the next 90 days, use the recommendations history to revert your choice.

    To dismiss the recommendation, click Dismiss, then confirm your choice. You can restore a dismissed recommendation as long as the recommendation is still valid.

  8. Repeat the previous steps until you have reviewed all of your recommendations.

gcloud

Review your recommendations:

To list your recommendations, run the gcloud recommender recommendations list command:

gcloud recommender recommendations list \
    --location=global \
    --recommender=google.iam.policy.Recommender \
    --RESOURCE_TYPE=RESOURCE_ID \
    --format=FORMAT

Replace the following values:

  • RESOURCE_TYPE: The resource type that you want to list recommendations for. Use the value project, folder, or organization.
  • RESOURCE_ID: The ID of the Google Cloud project, folder, or organization that you want to list recommendations for. Project IDs are alphanumeric strings, like my-project. Folder and organization IDs are numeric, like 123456789012.
  • FORMAT: The format of the response. Use json or yaml.

The response is similar to the following example. In this example, a service account has not used any permissions from the Compute Admin role (roles/compute.admin) in the past 90 days. As a result, the role recommendation suggests that you revoke the role:

[

              "pathFilter": {
                "/iamPolicy/bindings/*/condition/expression": "",

                "/iamPolicy/bindings/*/role": "roles/compute.admin"
              },
              "resource": "//cloudresourcemanager.googleapis.com/projects/example-project",
              "resourceType": "cloudresourcemanager.googleapis.com/Project"
            }
          ]
        }
      ]
    },
    "description": "This role has not been used during the observation window.",

      "category": "SECURITY",
      "securityProjection": {
        "details": {
          "revokedIamPermissionsCount": 708
        }
      }
    },
    "priority": "P4",
    "stateInfo": {
      "state": "ACTIVE"
    }
  }
]

Review each recommendation carefully, and consider how it will change the principal's access to Google Cloud resources. To learn how to review recommendations from the gcloud CLI, see Review recommendations on this page.

To apply a recommendation:

  1. Use the gcloud recommender recommendations mark-claimed command to change the recommendation's state to CLAIMED, which prevents the recommendation from changing while you apply it:

    gcloud recommender recommendations mark-claimed \
        RECOMMENDATION_ID \
        --location=global \
        --recommender=google.iam.policy.Recommender \
        --RESOURCE_TYPE=RESOURCE_ID \
        --format=FORMAT \
        --etag=ETAG \
        --state-metadata=STATE_METADATA
    

    Replace the following values:

    • RECOMMENDATION_ID: The unique identifier for the recommendation. This value appears at the end of the name field in the recommendation. In the example shown above, the ID is fb927dc1-9695-4436-0000-f0f285007c0f.
    • RESOURCE_TYPE: The resource type that you want to manage recommendations for. Use the value project, folder, or organization.
    • RESOURCE_ID: The ID of the Google Cloud project, folder, or organization that you want to manage recommendations for. Project IDs are alphanumeric strings, like my-project. Folder and organization IDs are numeric, like 123456789012.
    • FORMAT: The format of the response. Use json or yaml.
    • ETAG: The value of the etag field in the recommendation, such as "dd0686e7136a4cbb". Note that this value can include quotes.
    • STATE_METADATA: Optional. Comma-separated key-value pairs that contain your choice of metadata about the recommendation. For example, --state-metadata=reviewedBy=alice,priority=high. The metadata replaces the stateInfo.stateMetadata field in the recommendation.

    If the command succeeds, the response shows the recommendation in a CLAIMED state, as shown in the following example. For clarity, the example omits most fields:

    [
      {
        "description": "This role has not been used during the observation window.",
        "recommenderSubtype": "REMOVE_ROLE",
        "etag": "\"df7308cca9719dcc\"",
        "name": "projects/123456789012/locations/global/recommenders/google.iam.policy.Recommender/recommendations/fb927dc1-9695-4436-0000-f0f285007c0f",
        "stateInfo": {
          "state": "CLAIMED",
          "stateMetadata": {
            "reviewedBy": "alice",
            "priority": "high"
          }
        }
      }
    ]
  2. Get the allow policy for the project, then modify the allow policy so that it reflects the recommendation.

  3. Update the recommendation's state to SUCCEEDED, if you were able to apply the recommendation, or FAILED, if you could not apply the recommendation:

    gcloud recommender recommendations COMMAND \
        RECOMMENDATION_ID \
        --location=global \
        --recommender=google.iam.policy.Recommender \
        --RESOURCE_TYPE=RESOURCE_ID \
        --format=FORMAT \
        --etag=ETAG \
        --state-metadata=STATE_METADATA
    

    Replace the following values:

    • COMMAND: Use mark-succeeded, if you were able to apply the recommendation, or mark-failed, if you could not apply the recommendation.
    • RECOMMENDATION_ID: The unique identifier for the recommendation. This value appears at the end of the name field in the recommendation. In the example shown above, the ID is fb927dc1-9695-4436-0000-f0f285007c0f.
    • RESOURCE_TYPE: The resource type that you want to manage recommendations for. Use the value project, folder, or organization.
    • RESOURCE_ID: The ID of the Google Cloud project, folder, or organization that you want to manage recommendations for. Project IDs are alphanumeric strings, like my-project. Folder and organization IDs are numeric, like 123456789012.
    • FORMAT: The format of the response. Use json or yaml.
    • ETAG: The value of the etag field in the recommendation, such as "dd0686e7136a4cbb". Note that this value can include quotes.
    • STATE_METADATA: Optional. Comma-separated key-value pairs that contain your choice of metadata about the recommendation. For example, --state-metadata=reviewedBy=alice,priority=high. The metadata replaces the stateInfo.stateMetadata field in the recommendation.

    For example, if you marked the recommendation as having succeeded, the response shows the recommendation in a SUCCEEDED state. For clarity, this example omits most fields:

    [
      {
        "description": "This role has not been used during the observation window.",
        "recommenderSubtype": "REMOVE_ROLE",
        "etag": "\"dd0686e7136a4cbb\"",
        "name": "projects/123456789012/locations/global/recommenders/google.iam.policy.Recommender/recommendations/fb927dc1-9695-4436-0000-f0f285007c0f",
        "stateInfo": {
          "state": "SUCCEEDED",
          "stateMetadata": {
            "reviewedBy": "alice",
            "priority": "high"
          }
        }
      }
    ]

REST

These instructions assume that you have authenticated and set the GOOGLE_APPLICATION_CREDENTIALS environment variable.

Review your recommendations:

To list all available recommendations for your project, use the Recommender API's recommendations.list method.

Before using any of the request data, make the following replacements:

  • RESOURCE_TYPE: The type of the resource that you want to manage recommendations for. Use the value projects, folders, or organizations.
  • RESOURCE_ID: The ID of the Google Cloud project, folder, or organization that you want to manage recommendations for. Project IDs are alphanumeric strings, like my-project. Folder and organization IDs are numeric, like 123456789012.
  • PAGE_SIZE: Optional. The maximum number of results to return from this request. If not specified, the server will determine the number of results to return. If the number of recommendations is greater than the page size, the response contains a pagination token that you can use to retrieve the next page of results.
  • PAGE_TOKEN: Optional. The pagination token returned in an earlier response from this method. If specified, the list of recommendations will start where the previous request ended.
  • FILTER: Optional. A filter expression to restrict the recommendations returned. You can filter recommendations based on the stateInfo.state field. For example, stateInfo.state:"DISMISSED" or stateInfo.state:"FAILED".

HTTP method and URL:

Review recommendations

Each recommendation includes information to help you understand why the recommendation was made.

Console

To help you understand why the recommendation was made, the Google Cloud console shows the principal's permission usage, as reported by the policy insight associated with the recommendation. For example, it might show a list like the following:

To help you understand the impact of applying the recommendation, the Google Cloud console also shows a color- and symbol-coded list of permissions. This list indicates how the principal's permissions will change if you apply the recommendation. For example, it might show a list like the following:

The types of permissions associated with each color and symbol are as follows:

  • Gray with no symbol: Permissions that are in both the principal's current role and the recommended roles.

  • Red with a minus sign : Permissions that are in the principal's current role, but not in the recommended roles because the principal hasn't used them in the past 90 days.

  • Green with a plus sign : Permissions that are not in the principal's current role, but are in the recommended roles. This type of permission appears only in recommendations for Google-managed service accounts.

  • Blue with a Machine learning icon : Permissions that are in both the principal's current role and the recommended roles, not because the principal has used the permissions in the past 90 days, but because Recommender has determined through machine learning that they are likely to need those permissions in the future.

Some recommendations are also associated with lateral movement insights. Lateral movement insights identify roles that allow a service account in one project to impersonate a service account in another project. If a recommendation is associated with a lateral movement insight, the Google Cloud console also shows the following:

  • The service account's origin project: The project that the service account with impersonation permissions was created in.

  • Service accounts that can be impersonated in this project: A list of all of the service accounts in the current project that the service account with impersonation permissions can impersonate.
