Searching IAM policies samples

This page contains sample queries for various IAM policy search use cases.

Use Case: List IAM policies within your organization and format the output as tuples (RESOURCE, ROLE, MEMBER)

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456 \
  --page-size=50 \
  --flatten='policy.bindings[].members[]' \
  --format='table(resource, policy.bindings.role, policy.bindings.members)'

You can change the --scope to projects/12345678 or folders/1234567 to search within a project or folder instead of an organization.

You can add --query restrictions to get more specific resource search results.

You can add --asset-types restrictions to get more specific types of resources.

You can remove the --flatten and --format, if you don't want to format the results.

You can use csv instead of table to format the results into a csv.

You can add --limit to only get a subset of the search results. Without this flag, it will automatically page through all the search results.

Use Case: List IAM policies within your project

  gcloud asset search-all-iam-policies \
  --scope=projects/12345678

You can change the --scope to organizations/123456 or folders/1234567 to list all the IAM policies within your organization or folder instead of a project.

You can add --query restrictions to get more specific policy search results.

Use Case: List IAM policies that are set on resources with the word "foo" in the resource names

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456  \
  --query='resource:foo'

Use Case: List IAM policies that are set on organization/folder/project resources within your organization

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456  \
  --asset-types='cloudresourcemanager.*'

You can change the --asset-types flag to cloudresourcemanager.googleapis.com/Project to scope the search for only project resources.

Use Case: List viewers of a project

  gcloud asset search-all-iam-policies \
  --scope=projects/12345678 \
  --query='roles:roles/viewer' \
  --asset-types='cloudresourcemanager.*'
  --page-size=50 \
  --flatten='policy.bindings[].members[]' \
  --format='table(policy.bindings.members)'

Note: The command only returns the viewers from the IAM policies directly set on the project, but doesn't extend to searching the policies inherited from the project's parent resources.

Use Case: List projects where a user has the owner role

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456 \
  --query='policy:(roles/owner [e-mail])' \
  --asset-types='cloudresourcemanager.googleapis.com/Project'
  --page-size=50 \
  --format='table(resource)'

Note: The command only returns the projects whose direct IAM policies specify the user and the owner role, but doesn't extend to searching the policies inherited from the projects' parent resources.

Use Case: List roles that a user has upon a project

  gcloud asset search-all-iam-policies \
  --scope=projects/12345678 \
  --query='policy:[e-mail]' \
  --asset-types='cloudresourcemanager.googleapis.com/Project'
  --page-size=50 \
  --flatten='policy.bindings[]' \
  --format='table(policy.bindings.role)'

Note: The command only returns the roles from the IAM policies directly set on the project, but doesn't extend to searching the policies inherited from the project's parent resources.

Use Case: List permissions that a user has upon a project

  gcloud asset search-all-iam-policies \
  --scope=projects/12345678 \
  --query='policy:[e-mail] policy.role.permissions:""' \
  --asset-types='cloudresourcemanager.*'
  --page-size=50 \
  --format='default(explanation.matchedPermissions)'

Note: The command only returns the user's permissions obtained from the IAM policies directly set on the project, but doesn't extend to searching the policies inherited from the project's parent resources.

Use Case: List users that can access bigstore bucket

  gcloud asset search-all-iam-policies \
  --scope=projects/12345678 \
  --query='policy.role.permissions:storage.buckets' \
  --asset-types='cloudresourcemanager.*'
  --page-size=50 \
  --flatten='policy.bindings[].members[]' \
  --format='table(policy.bindings.members)'

Use Case: List service accounts that have owner role in order to detect risky policy settings

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456 \
  --query='policy:(roles/owner serviceAccount)' \
  --page-size=50 \
  --flatten='policy.bindings[].members[]' \
  --format='table(resource.segment(3):label=RESOURCE_TYPE, resource.basename():label=RESOURCE, policy.bindings.members)' \
  | grep serviceAccount

Note: Unlike the other commands, this should be run only in the Cloud Shell, because of the presence of Linux-specific commands.

Use Case: List resources that can be accessed by Gmail users

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456 \
  --query='policy:gmail.com' \
  --page-size=50 \
  --flatten='policy.bindings[].members[]' \
  --format='csv(resource, policy.bindings.role, policy.bindings.members)' \
  | grep @gmail.com

Note: Unlike the other commands, this should be run only in the Cloud Shell, because of the presence of Linux-specific commands.

Use Case: List resources that have roles granted to the whole domain

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456 \
  --query='policy:"domain:bigwhite.joonix.net"' \
  --page-size=50 \
  --flatten='policy.bindings[]' \
  --format='table(resource, policy.bindings.role)'

Use Case: List resources that have roles granted to the public

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456 \
  --query='memberTypes:(allUsers OR allAuthenticatedUsers)' \
  --page-size=50 \
  --format='table(resource)'

Use Case: List users/groups who can change IAM policies on organization/folder/project

  gcloud asset search-all-iam-policies \
  --scope=organizations/123456 \
  --query='policy.role.permissions:(resourcemanager.organizations.setIamPolicy OR resourcemanager.folders.setIamPolicy OR resourcemanager.projects.setIamPolicy)' \
  --page-size=50 \
  --format='json(resource, policy.bindings, explanation.matchedPermissions)'
