In the Principal column, find all rows that identify you or a group that
you're included in. To learn which groups you're included in, contact your

For all rows that specify or include you, check the Role column to see whether
the list of roles includes the required roles.

Perform this task\nif your organization uses VPC Service Controls to restrict services in projects that\nyou want VM Threat Detection to scan. For more information about\nVM Threat Detection, see\n[VM Threat Detection overview](/security-command-center/docs/concepts-vm-threat-detection-overview).\n\nBefore you begin\n\n\nMake sure that you have the following role or roles on the organization:\n\nAccess Context Manager Editor\n(`roles/accesscontextmanager.policyEditor`).\n\nCheck for the roles\n\n1.\n In the Google Cloud console, go to the **IAM** page.\n\n [Go to IAM](https://console.cloud.google.com/projectselector/iam-admin/iam?supportedpurview=organizationId)\n2. Select the organization.\n3.\n In the **Principal** column, find all rows that identify you or a group that\n you're included in.

In the **Select a role** list, select a role.\n6. To grant additional roles, click add **Add\n another role** and add each additional role.\n7. Click **Save**.\n\nCreate the egress and ingress rules\n\nTo allow VM Threat Detection to scan the VMs in VPC Service Controls perimeters, add\nthe required egress and ingress rules in those perimeters. Perform these steps\nfor each perimeter that you want VM Threat Detection to scan.\n\nFor more information, see\n[Updating ingress and egress policies for a service perimeter](/vpc-service-controls/docs/configuring-ingress-egress-policies#console)\nin the VPC Service Controls documentation.\n\n\nConsole\n\n1.

Select your organization or project.\n3. If you selected an organization, click **Select an access policy** and then select the access policy associated with the perimeter that you want to update.\n4. Click the name of the perimeter that you want to update.\n\n\n To find the service perimeter you need to modify, you can check your logs for entries\n that show `RESOURCES_NOT_IN_SAME_SERVICE_PERIMETER` violations. In those\n entries, check the `servicePerimeterName` field: \n\n ```\n accessPolicies/ACCESS_POLICY_ID/servicePerimeters/SERVICE_PERIMETER_NAME\n ```\n5. Click edit **Edit perimeter**.\n6. Click **Egress policy**.\n7. Click **Add an egress rule**.\n8. In the **FROM** section, set the following details:\n\n 1. For **Identity** , select **Select identities \\& groups**.\n 2. Click **Add identities**\n 3.\n Enter the email address of the\n\n [Security Center service agent](/security-command-center/docs/access-control-org#service-agent).\n\n\n The service agent's address has the\n following format:\n\n ```\n service-org-ORGANIZATION_ID@security-center-api.iam.gserviceaccount.com\n ```\n\n Replace \u003cvar translate=\"no\"\u003eORGANIZATION_ID\u003c/var\u003e with your organization ID.\n 4.
