Use tags to manage access to purchase orders

You can use attribute-based access control (ABAC) to manage access to your purchase orders. When you create your purchase orders, you can tags with key-value pairs. You can then create IAM policies and specify the tags. For example, if you add the project key and assign it a value of test, your IAM policies can explicitly allow or deny access to any purchase order that has this tag.

To add tags to new purchase orders or update existing ones, see Adding a purchase order and Editing your purchase orders.

Example: Use tags to allow access

The following policy allows the IAM entity to add, modify, or tag purchase orders that have the project key and a value of test.

{
    "Version": "2012-10-17",
    "Statement": [{
        "Effect": "Allow",
        "Action": [
            "purchase-orders:AddPurchaseOrder",
            "purchase-orders:TagResource",
            "purchase-orders:ModifyPurchaseOrders"
        ],
        "Resource": "arn:aws:purchase-orders::*:purchase-order/*",
        "Condition": {
            "StringEquals": {
                "aws:RequestTag/project": "test"
            },
            "ForAllValues:StringEquals": {
                "aws:TagKeys": "project"
            }
        }
    }]
}
Example: Use tags to deny access

The following policy denies the IAM entity from completing any purchase order action on purchase orders that have the project key and a value of test.

{
    "Version": "2012-10-17",
    "Statement": [{
        "Effect": "Deny",
        "Action": "purchase-orders:*",
        "Resource": "arn:aws:purchase-orders::*:purchase-order/*",
        "Condition": {
            "StringEquals": {
                "aws:ResourceTag/Project": "test"
            }
        }
    }]
}
