[Create a Private Service Connect Secure Source Manager instance](/secure-source-manager/docs/create-private-service-connect-instance).\n2. [Create a VPC Service Controls perimeter](/vpc-service-controls/docs/create-service-perimeters).\n\n### Required roles\n\n\nTo get the permissions that\nyou need to configure Secure Source Manager in a VPC Service Controls perimeter,\n\nask your administrator to grant you the\nfollowing IAM roles on the organization:\n\n- [Access Context Manager Admin role](/iam/docs/roles-permissions/accesscontextmanager#accesscontextmanager.policyAdmin) (`roles/accesscontextmanager.policyAdmin`)\n- [Project Creator](/iam/docs/roles-permissions/resourcemanager#resourcemanager.projectCreator) (`roles/resourcemanager.projectCreator`)\n\n\nFollow best practices\n---------------------\n\nCareless enablement of VPC Service Controls can cause problems with existing\napplications and could potentially cause an outage. We recommend that you plan\nenablement carefully and allow ample time to gather data, conduct tests, and\nanalyze violation logs. Make sure that stakeholders from your\nVPC Service Controls operations team and your applications team are available for\nthe task.\n\nFor more information on best practices, see\n[Best practices for enabling VPC Service Controls](/vpc-service-controls/docs/enable)\n\nAdd your project to the perimeter\n---------------------------------\n\n1. In the Google Cloud console, go to the **VPC Service Controls** page.\n\n [Go to VPC Service Controls](https://console.cloud.google.com/security/service-perimeter)\n2. On the **VPC Service Controls** page, select the perimeter you want to use\n to protect your project.\n\n3. On the **VPC Service Control enforced config detail** page, click **Edit**\n in the **resources to protect** section.\n\n4. Click **Resources to protect** and add your project ID.\n\n5. Click **Save**.\n\nAdd Secure Source Manager as a restricted service\n-------------------------------------------------\n\n1. In the Google Cloud console, go to the **VPC Service Controls** page.\n\n [Go to VPC Service Controls](https://console.cloud.google.com/security/service-perimeter)\n2. On the **VPC Service Controls** page, select the perimeter you added your\n project to.\n\n3. On the **VPC Service Control enforced config detail** page, click **Edit**\n in the **Restricted services** section.\n\n4. Click **Add services**.\n\n5. In the **Specify services to restrict** dialog, select the checkbox next to\n Secure Source Manager. You can use the filter query to locate Secure Source Manager in\n the list.\n\n6. Click **Save**.\n\nAfter you update a service perimeter, it can take up to 30 minutes for the\nchanges to propagate and take effect. During this time, the perimeter might\nblock requests with the following error message: \n\n Error 403: Request is prohibited by organization's policy.\n\nWhat's next\n-----------\n\n- Learn more about [Private Service Connect](/vpc/docs/private-service-connect).\n- Learn more about [Connecting to VMs without external IP addresses](/solutions/connecting-securely#external)."]]
