An enterprise organization is establishing a standardized self-service provisioning and access management workflow for engineering teams in Google Cloud. The cloud architecture team must implement an access lifecycle model that meets the following security and governance requirements: Developers must be able to discover and request workload access through a self-service workflow with approval and justification. Access must automatically lapse after a defined time window to maintain Zero Standing Privileges (ZSP) and prevent privilege accumulation. Direct role assignments to individual user identities must be avoided across all environments. Automated project provisioning workflows must prevent services from receiving default, overly permissive roles such as roles/editor upon creation. Which combination of IAM and governance controls should you implement?

Manage access using workload-specific access groups integrated with a Just-In-Time (JIT) self-service tool with auto-expiring memberships, assign IAM roles to these groups, and enforce the `constraints/iam.automaticIamGrantsForDefaultServiceAccounts` organization policy constraint.: ### What Workload Access Groups and JIT Lifecycle Management Are Workload-specific **access groups** and **Just-In-Time (JIT) group management tools** provide a scalable, self-service mechanism for governing permissions across Google Cloud resources. Instead of binding IAM roles directly to individual users, roles are assigned to dedicated access groups representing specific job functions. A self-service tool (such as JIT Groups) evaluates access requests, enforces justification and approval workflows, and automatically expires user memberships when the approved duration concludes. ### How It Meets the Requirements - **Self-service discovery and approvals**: Dedicated access group management tools allow developers to discover workload groups, submit business justifications, and route requests to designated workload owners for approval. - **Zero Standing Privileges (ZSP)**: Auto-expiring group memberships add friction to long-term access retention, automatically revoking user membership and preventing gradual privilege creep over time. - **Group-based role assignment**: Assigning IAM roles to access groups rather than individual user identities simplifies auditing and adheres to foundational IAM best practices. - **Preventing overly permissive defaults**: Enforcing the `iam.automaticIamGrantsForDefaultServiceAccounts` organization policy constraint disables the automatic assignment of `roles/editor` when new services or projects are provisioned. ### Key Advantages - **Reduced administrative overhead**: Workload owners manage group membership approvals without needing administrative IAM privileges on the project hierarchy. - **Comprehensive audit trail**: JIT tooling captures access request justifications, approver IDs, and timestamps in central audit logs. - **Enforced least privilege**: Prevents newly created service accounts from acquiring broad default project permissions. - **Automated decommissioning of access**: Timed membership revocation ensures access terminates automatically without requiring manual deprovisioning scripts. ### Why This Is Optimal Combining JIT-managed access groups with organization policy constraints establishes a secure, repeatable self-service model. It enforces least-privilege access during runtime and guarantees baseline guardrails are inherited by every newly provisioned project.

An enterprise organization is establishing a standardized self-service provisioning and access management workflow for engineering teams in Google Cloud. The cloud architecture team must implement an access lifecycle model that meets the following security and governance requirements:

Developers must be able to discover and request workload access through a self-service workflow with approval and justification.
Access must automatically lapse after a defined time window to maintain Zero Standing Privileges (ZSP) and prevent privilege accumulation.
Direct role assignments to individual user identities must be avoided across all environments.
Automated project provisioning workflows must prevent services from receiving default, overly permissive roles such as roles/editor upon creation.

Which combination of IAM and governance controls should you implement?

Utilize Cloud Identity Groups for Business collaboration groups for IAM role assignments, and delegate group creation and membership management directly to all developers without approval guardrails.

Manage access using workload-specific access groups integrated with a Just-In-Time (JIT) self-service tool with auto-expiring memberships, assign IAM roles to these groups, and enforce the constraints/iam.automaticIamGrantsForDefaultServiceAccounts organization policy constraint.

Assign IAM roles directly to individual developer accounts using IAM Conditions with scheduled expiration timestamps, while allowing default service account provisioning during project creation.

Grant standing primitive Owner roles to developers via a central infrastructure pipeline, and schedule automated nightly scripts to delete and recreate project IAM policies.
