**To apply a stack policy**

The following ``set-stack-policy`` example disables updates for the specified resource in the specified stack. ``stack-policy.json`` is a JSON document that defines the operations allowed on resources in the stack. ::

    aws cloudformation set-stack-policy \
        --stack-name my-stack \
        --stack-policy-body file://stack-policy.json

Output::

    {
      "Statement" : [
        {
          "Effect" : "Allow",
          "Action" : "Update:*",
          "Principal": "*",
          "Resource" : "*"
        },
        {
          "Effect" : "Deny",
          "Action" : "Update:*",
          "Principal": "*",
          "Resource" : "LogicalResourceId/bucket"
        }
      ]
    }
