Pivotal Cloud Foundry IaaS User Role Guidelines
This topic describes practices recommended by Pivotal for creating secure IaaS user roles.
Pivotal Cloud Foundry (PCF) is an automated platform that connects to IaaS providers such as AWS and OpenStack. This connectivity typically requires accounts with appropriate permissions to act on behalf of the operator to access IaaS functionality such as creating virtual machines (VMs), managing networks and storage, and other related services.
Ops Manager and Elastic Runtime can be configured with IaaS users in different ways depending on your IaaS. Other product tiles and services might also use their own IaaS credentials. Refer to the documentation for those product tiles or services to configure them securely.
Pivotal recommends following the principle of least privilege by scoping privileges to the most restrictive permissions possible for a given role. In the event that someone gets access to credentials by mistake or through malicious intent, LPUs limit the scope of the breach. Pivotal recommends following best practices for the particular IaaS you are deploying.
Pivotal recommends using the CloudFormation templates for Pivotal Cloud Foundry to configure AWS deployments to create users with least privilege. Pivotal also recommends minimizing the use of master account credentials by creating an IAM role and instance profile with the minimum required EC2, VPC, and EBS credentials.
Note: If you choose not to use the CloudFormation templates, Pivotal encourages you to use the permissions determined by
PcfIamPolicy section of the Ops Manager CloudFormation template to create users with appropriate permissions. Additionally, follow AWS account security best practices such as disabling root keys, multi-factor authentication on the root account, and CloudTrail for auditing API actions.
See the table below for more information on the two CloudFormation templates.
|Template Source||Location||User(s) Created||User Purpose||Uses IAM Role||Additional Documentation|
