# Creating permission sets
<a name="creating-permission-sets"></a>

You can manage AWS account access by using [permission sets](https://docs.aws.amazon.com/singlesignon/latest/userguide/permissionsetsconcept.html) in AWS IAM Identity Center. A *permission set* is a template that helps you deploy one or more IAM policies to multiple AWS accounts. When you assign a permission set to an AWS account, IAM Identity Center creates an IAM role and attaches your IAM policies to that role. For more information, see [Create and manage permission sets](https://docs.aws.amazon.com/singlesignon/latest/userguide/permissionsets.html) (IAM Identity Center documentation).

AWS recommends creating permission sets that map to the different personas in your business.

+ [Developer permission set](#developer-permission-set)
+ [Production permission set](#production-permission-set)

The following permissions sets are snippets from an AWS CloudFormation template. You should use this code as a starting point and customize it for your business. For more information about CloudFormation templates, see [Learn template basics](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/gettingstarted.templatebasics.html) (CloudFormation documentation).

## Billing permission set
<a name="billing-permission-set"></a>

The finance team uses **BillingAccessPermissionSet** to view the AWS Billing console dashboard and AWS Cost Explorer in each account.

```
BillingAccessPermissionSet:
  Type: "AWS::SSO::PermissionSet"
  Properties:
    Description: Access to Billing and Cost Explorer
    InstanceArn: !Sub "arn:${AWS::Partition}:sso:::instance/ssoins-instanceId"
    ManagedPolicies:
      - !Sub "arn:${AWS::Partition}:iam::aws:policy/job-function/Billing"
    Name: BillingAccess
    SessionDuration: PT8H
    RelayStateType: https://console.aws.amazon.com/billing/home
```

## Developer permission set
<a name="developer-permission-set"></a>

The engineering team uses **DeveloperAccessPermissionSet** to access non-production accounts.

```
DeveloperAccessPermissionSet:
  Type: "AWS::SSO::PermissionSet"
  Properties:
    Description: Access to provision resources through CloudFormation
    InlinePolicy: !Sub |-
      {
        "Version": "2012-10-17",

              },
              "Null": {
                "cloudformation:ImportResourceTypes": true
              }
            }
          },
          {
            "Effect": "Allow",

            ],
            "Resource": "*"

        ]
      }

## Production permission set
