To view IAM policies, you can use the Google Cloud Console, gcloud CLI, or the REST API. In the Console, navigate to 'IAM & Admin' from the main menu, then select 'IAM' to see all members and their assigned roles for the current project. You can switch between projects, folders, or organization levels to view policies at different hierarchy levels.
Using gcloud CLI, the command 'gcloud projects get-iam-policy PROJECT_ID' retrieves the IAM policy for a specific project. For organizations, use 'gcloud organizations get-iam-policy ORG_ID', and for folders, use 'gcloud resource-manager folders get-iam-policy FOLDER_ID'. Adding '--format=json' or '--format=yaml' outputs the policy in your preferred format.
IAM policies consist of bindings that connect members (users, service accounts, groups) to roles. When viewing policies, you'll see role assignments like 'roles/editor' or 'roles/viewer' mapped to identities such as 'user:example@gmail.com' or 'serviceAccount:sa@project.iam.gserviceaccount.com'.
The Policy Analyzer tool provides advanced capabilities for understanding effective permissions. It helps answer questions like 'Who can access this resource?' or 'What resources can this user access?' This is particularly useful for complex environments with inherited permissions.
For individual resources like Cloud Storage buckets or Compute Engine instances, you can view resource-level IAM policies through their respective console pages or using resource-specific gcloud commands like 'gcloud storage buckets get-iam-policy BUCKET_NAME'.
Regularly reviewing IAM policies helps ensure the principle of least privilege is maintained, identifying overly permissive access or unused permissions that could pose security risks.
Viewing IAM Policies in Google Cloud Platform
Why Viewing IAM Policies is Important
Understanding how to view IAM policies is fundamental for cloud security and access management. IAM policies define who has what level of access to which resources in your GCP environment. Being able to view these policies allows you to:
• Audit current access permissions across your organization • Troubleshoot access-related issues when users cannot perform expected actions • Ensure compliance with security requirements and least privilege principles • Identify potential security risks from overly permissive access
What Are IAM Policies?
An IAM policy is a collection of bindings that associate one or more members (users, service accounts, groups, or domains) with a specific role. Each binding grants the permissions defined in that role to the specified members for a particular resource.
IAM policies exist at multiple levels in GCP: • Organization level - applies to all resources in the organization • Folder level - applies to all projects within the folder • Project level - applies to all resources within the project • Resource level - applies to specific resources like Cloud Storage buckets or Compute Engine instances
How to View IAM Policies
Using the Google Cloud Console: 1. Navigate to IAM & Admin in the Cloud Console 2. Select IAM from the left menu 3. Choose the appropriate project, folder, or organization 4. View the list of members and their assigned roles
Using gcloud CLI:
To view project-level IAM policy: gcloud projects get-iam-policy PROJECT_ID
To view organization-level IAM policy: gcloud organizations get-iam-policy ORGANIZATION_ID
To view folder-level IAM policy: gcloud resource-manager folders get-iam-policy FOLDER_ID
To view resource-specific IAM policy (example for Cloud Storage): gcloud storage buckets get-iam-policy gs://BUCKET_NAME
Output Format Options: Add --format=json or --format=yaml to get structured output for easier parsing and review.
Understanding Policy Output
When you view an IAM policy, you will see: • bindings - array of role-to-member associations • etag - used for concurrency control when updating policies • version - policy version number (1, 2, or 3)
Exam Tips: Answering Questions on Viewing IAM Policies
• Know the correct commands: Remember that get-iam-policy is used for viewing, while set-iam-policy is used for updating policies
• Understand hierarchy inheritance: Policies are inherited from parent resources. A user granted access at the organization level will have that access in all folders and projects below
• Differentiate between roles and permissions: Roles contain permissions. When viewing policies, you see role assignments, not individual permissions
• Remember resource-specific commands: Different resource types may have slightly different commands for viewing their IAM policies
• Policy version matters: Version 3 policies support conditional role bindings. Be aware of policy versions when answering questions about IAM conditions
• Console vs CLI: Know that both methods provide the same information, but CLI offers more flexibility for scripting and automation
• Principle of least privilege: When asked about best practices for reviewing policies, emphasize checking for overly broad access and ensuring minimal necessary permissions
• Effective policy: Remember that the effective policy for a resource is the combination of policies set on that resource and all its ancestors in the hierarchy
