Require OS Login

01 Sign in to Google Cloud Management Console with the organizational unit credentials.

02 Click on the deployment selector from the top navigation bar, select ALL to list all the existing deployments, then choose the Google Cloud organization that you want to examine.

03 Navigate to Cloud Identity and Access Management (IAM) dashboard at https://console.cloud.google.com/iam-admin/iam.

04 In the navigation panel, select Organization Policies to access the list with the cloud organization policies available for your GCP organization.

05 Click inside the Filter by policy name or ID filter box, select Require OS Login to return the "Require OS Login" policy.

06 Click on the name of the GCP organization policy returned at the previous step.

07 On the Policy details page, under Effective policy, check the Enforcement configuration attribute status. If the Enforcement attribute status is set to Not enforced, the policy is not enforced for your GCP organization, therefore the OS Login feature is not enabled by default for all newly created Google Cloud projects within the selected organization.

08 Repeat steps no. 2 – 7 for each organization available in your Google Cloud account.

01 Run organizations list command (Windows/macOS/Linux) using custom query filters to list the ID of each GCP organization created within your Google Cloud account:

gcloud organizations list
    --format="table(name)"

02 The command output should return the requested organization identifiers (IDs):

ID
112233441122
123412341234

03 Run resource-manager org-policies describe command (Windows/macOS/Linux) using the ID of the GCP organization that you want to examine as identifier parameter, to describe the enforcement configuration of the "Require OS Login" policy, available for the selected organization:

gcloud alpha resource-manager org-policies describe
"compute.requireOsLogin"
    --effective
    --organization=112233441122
    --format="table(booleanPolicy)"

04 The command request should return the requested configuration information:

BOOLEAN_POLICY
{}

05 Repeat step no. 3 and 4 for each organization created within your Google Cloud account.

01 Sign in to Google Cloud Management Console with the organizational unit credentials.

02 Click on the deployment selector from the top navigation bar, select ALL to list all the existing deployments, then choose the Google Cloud organization that you want to reconfigure.

03 Navigate to Cloud Identity and Access Management (IAM) dashboard at https://console.cloud.google.com/iam-admin/iam.

04 In the navigation panel, select Organization Policies to access the list with the cloud organization policies available for your GCP organization.

05 Click inside the Filter by policy name or ID box, select Require OS Login to list only the "Require OS Login" policy.

06 Click on the name of the GCP organization policy listed at the previous step.

07 On the Policy details page, click on the EDIT button from the dashboard top menu to edit the selected policy.

08 On the Edit policy configuration page, perform the following actions:

1. Under Applies to, select Customize to choose the type of the policy to apply (i.e. customized policy).
2. Under Enforcement, select On to enable the "Require OS Login" policy for the selected GCP organization.
3. Click SAVE to apply the changes and enforce the constraint policy at the organization level.

09 If required, repeat steps no. 2 – 8 to enable the required policy for other organizations available in your Google Cloud account.

01 Run resource-manager org-policies enable-enforce command (Windows/macOS/Linux) using the ID of the Google Cloud Platform (GCP) organization that you want to reconfigure as identifier parameter, to enforce the "Require OS Login" policy (i.e. "compute.requireOsLogin" constraint) for the selected GCP organization:

gcloud alpha resource-manager org-policies enable-enforce
"compute.requireOsLogin"
    --organization=112233441122

02 The command request should return the reconfigured organization policy metadata:

booleanPolicy:
  enforced: true
constraint: constraints/compute.requireOsLogin
etag: abcdabcdabcd
updateTime: '2020-09-14T15:00:00.000Z'

03 If required, repeat step no. 1 and 2 to enforce the necessary policy for other GCP organizations created within your Google Cloud account.
